How to Air Seal an Attic

Throughout many homes, there are plenty of spaces that air can enter and exit. While tiny cracks and crevices may not seem like much, their combined effect can make a big impact on your home’s energy use. Air leakage in the average house has the cumulative effect of leaving a window open 24/7. Luckily, there are several ways to reduce outdoor air infiltration – one of which involves learning how to air seal attic crawl spaces.  

In the winter, attic insulation installation and air sealing can prevent heat loss that can save nearly a third of the energy your furnaces use. The same goes for the summer, where many homeowners have to spend big money trying to keep their space comfortable. Air sealing combined with proper insulation and adequate ventilation can save you about 15% on your monthly bills, which can translate into thousands of dollars over the course of a few years. It can also prevent pests from entering your home, provide even heating and cooling from room to room, improve your indoor air quality, and save you money on HVAC repairs. 

So, is air sealing the attic worth it? And if so, how do you approach this project? The first step is identifying air leaks around the house. 

Detecting air leaks in your home

One simple way to discover an air leak is with smoke. If you turn off the AC and any fans in the house, you can light a stick of incense and move it around common problem points and watch for places where the smoke begins to move erratically. 

These places can be around windows, doors, cracks in the walls, ceiling, or floors. In the attic, you can check around light fixtures, electrical connections, and near vents, chimneys, or other fixtures that go through the attic floor or ceiling. The attic space in your home shouldn’t have conditioned air, so places such as the attic hatch and vents that lead up through the ceiling are just important to seal off. 

Another way to spot air leaks is to look for dirty or damaged insulation. However, you should never handle insulation without proper protection for your hands, face, and eyes. Older, existing insulation may contain asbestos, but even newer types of asbestos can irritate your skin and eyes, or damage your lungs if you breathe it in. 

An experienced contractor can perform this job efficiently, and they know how to handle all types of insulation safely. They have the experience and tools, such as thermal leak detectors, to make short work of this task. They can also ensure your attic still has adequate ventilation after you seal air leaks and add insulation. This will keep warm air from overstaying its welcome in the attic and prevent costly repairs from water damage. 

How to seal air leaks

Caulk can be used to seal cracks that are smaller than a ¼” in width. You can use weather-stripping to create an air barrier in cracks and spaces around doors, windows, and the attic access. For larger holes, such as the ones around lighting fixtures, you can use spray foam insulation, but installing it properly takes experience, and it can get expensive fast if you don’t use it wisely. 

For homes with single-pane windows, the cost of replacing each one can add up quickly. A more budget-friendly approach is to use window wrap on windows and to replace them with more energy-efficient models as you can in the future. Cracks in the floor can also cause a lot of air leakage, and there are a variety of fillers you can use depending on the type of flooring you have.

Sealing air leaks in your home is a long, time-consuming process, and hiring a contractor can save you a lot of time and energy while ensuring the job is done correctly. Of course, air sealing attic spaces can only go so far when it comes to keeping conditioned air inside your home. If you have insufficient ventilation or insulation, you likely won’t see the dramatic difference in your energy bill that you’re hoping for. 

The importance of insulation

Regardless of how well you can seal off air leaks, heat transfer can still occur unless you incorporate proper insulation. The team of insulation experts at Attic Construction understands how to properly install insulation and air seal attic spaces in your home as well as identify areas that are underinsulated. We will inspect places your HVAC system uses, such as inside an exterior wall, throughout the crawl space, in the attic, and around the air ducts. Even if you have existing insulation, it may not be sufficient. 

We can help you determine when to remove damaged insulation or supplement it, and educate you on which insulation will give you the best value for your money. We can blow in fiberglass insulation into wall cavities and fiberglass batts throughout your attic space. We will also inspect your ventilation system and make any repairs to ensure it’s up to the job. Insulation in the crawl space can prevent warm or cold air from entering your house from below as well as prevent a plumbing pipe from freezing weather. 

Once we’ve ensured you have adequate insulation and ventilation throughout your home, sealed any air leaks, and made necessary repairs to your ductwork, you should notice an immediate difference. Are you ready to experience the many benefits of air sealing attic spaces? This project will improve air flow for your AC and heater and prevent contaminants and allergens from affecting your indoor air quality, as well as lower your monthly energy use.

What Is The Most Eco-Friendly Insulation?

Just about everyone knows how important recycling and driving energy-efficient cars are to reducing your environmental impact, but did you know that your home’s insulation building material could also make a big difference in decreasing your carbon footprint? 

In this article, we’ll go over how having the right amount of insulation can help decrease your home’s CO2 emissions and talk about which types are the most eco friendly insulation materials. 

How Insulation Can Help Reduce Your Environmental Impact

Having enough insulation in your home is important to reducing your energy consumption. Because insulation determines how hard your heating and cooling systems have to work to keep your home at a regular temperature, installing the right home insulation materials can reduce your carbon emissions (and your energy bill).

Homes with proper insulation are better protected against outside weather, which means they only use a fraction of the energy to keep homes at a comfortable temperature. It’s estimated that buildings in the US with good insulation slash CO2 emissions by 780 million tons per year.1 

The problem is that only one in every ten homes in the US currently has the right amount of insulation needed for this kind of energy efficiency.2

So how can you tell if your home is underinsulated?

Signs Your Home Needs New Insulation 

Here are some things to look out for to determine whether or not your home has enough insulation:

  • Drafts in the house
  • Uneven temperature from room to room
  • Cold walls and floors 
  • High energy bills 
  • Poor sound barrier

If your home shows any of these signs, it’s likely that you’re wasting energy (and money!) due to poor insulation installation, and it’s time to replace it. 

How the Insulation Material You Choose Impacts the Environment

Having enough insulation in your home is important to lowering your home’s energy consumption, but not all insulation materials are equally as eco-friendly. Some materials actually risk increasing your environmental impact. 

To explain why, let’s take a look at spray foam.  

The Environmental Downsides of Spray Foam Insulation

Spray foam rose has risen in popularity as a form of insulation in recent years because of its vapor barrier and air sealing abilities. Unfortunately, these properties come with downsides for the environment. 

Spray foam gives off a ton of greenhouse gases, which depending on its chemical makeup, can be up to 1,400 times more damaging to the environment than carbon dioxide.3 Spray foam is also often treated with a variety of harsh chemicals to help keep them from becoming flammable. These chemicals can have a negative impact both on the environment and the air quality of your home if off-gassing occurs. 

The good news is there are a number of alternative insulation options that are much better for the environment.

Eco-Friendly Insulation Material   

When it comes to looking for an environmentally friendly insulation, here are some important factors to look for:

  • Material Quality – Insulation that is environmentally friendly will be made out of recycled material and have minimal chemical treatment. 
  • R-value – Materials with a high R-value will be better able to regulate heat flow in your home and therefore better at reducing your energy consumption. 
  • Longevity – Insulation that lasts a long time can reduce overall waste as it won’t need to be replaced as often.
  • Price – When looking at sustainable insulation materials, it’s important to make sure that you pick one that fits your budget.

Here’s how some of the top eco-friendly insulation materials compare based on these metrics:

  • Fiberglass (best option)
    • Made of between 40-60% recycled glass 
    • Has an R-value of between 2.2-4.3 
    • Can last up to 100 years 
    • Made out of low-cost material
  • Cellulose 
    • Made up of between 82-85% recycled paper 
    • Has an R-value between 3.2-3.5
    • Can last up to 30 years4
    • Made out of low-cost material
  • Cotton 
    • 85% recycled fibers and 15% chemically treated plastic 
    • Has an R-value between 3.4-3.7
    • Can last up to 100 years5
    • Made out of higher-priced material
  • Mineral Wool 
    • 75% recycled building material 
    • Has an R-value between 3.7-4.2 
    • Can last up to 100 years 
    • Made out of higher-priced material 

Which Insulation Material is The Most Eco-Friendly?

While having an insulation material made out of recycled contents is important, what matters most is finding an effective but affordable insulator that will help you reduce your long-term environmental impact. 

All the insulation types listed above have different strengths, but the fiberglass insulation product is the only one that meets all the green insulation standards. If you’re interested in installing insulation, learn more about fiberglass insulation costs here.

Cellulose vs Fiberglass Insulation

Insulation is essential to help protect your home from outside weather and keep your energy bill from skyrocketing. But not all insulation materials are made equally. If you’re undergoing a new construction project, you need to know which type of insulation fits your home’s unique requirements. There are many types of wall insulation materials from insulating concrete forms to foam board, as well as many types of attic insulation, including loose fill fiberglass insulation vs foam, blown in insulation, and more. 

Each insulation type has its own set of benefits and disadvantages that affect whether or not it’ll fit well with your home. Finding the insulation material that best suits you and your family’s unique needs can make all the difference in creating a safe and comfortable home environment.

To help you figure out which insulation product is best for you, we’re going to be comparing cellulose vs fiberglass insulation. 

The Basics of Fiberglass Insulation

If you’ve seen pink, cloud-like material in attics before, this is not an industrial form of cotton candy—this is traditional fiberglass insulation. Fiberglass is one of the most popular kinds of insulation and for good reason. It’s a low-cost but effective way of regulating the temperature in your home. 

But what is fiberglass attic insulation exactly? 

Fiberglass is a material made of tiny pieces of mostly recycled material such as glass that has been melted down, combined with other materials like sand and limestone, and then woven into long strands, giving it a cotton-like appearance.

Fiberglass comes in many different forms, but the two that are most commonly used for home insulation are batts and loose-fill fiberglass.

Fiberglass Batts

Batts are made up of large rolled-up sheets of fiberglass held together by either aluminum foil or adhesive paper.1

Batts are the most commonly used form of fiberglass insulation in homes because they make installation quick and convenient. Batt insulation is designed to fit between standard-sized joists, which means all you need to do to install is to unroll it and then attach.  

One downside to this type of insulation, though, is that it’s difficult to customize these pre-made rolls to fit different shapes. This makes it hard to install in attics with pipes or other obstructions between joists. 

That’s where loose-fill fiberglass comes in. 

Loose-fill Fiberglass 

Like batts, loose-fill fiberglass is also made up of tiny fibers of recycled glass. Instead of being woven into long blankets, though, they’re cut into small pieces which are then blown into place using an insulation-blowing machine. 

Loose fill insulation allows for people who cannot get batts installed in their attic due to obstructions or other reasons to still be able to enjoy the benefits of fiberglass insulation.

Pros and Cons of Fiberglass

One of the many reasons fiberglass is a popular choice among homeowners and attic professionals alike is that there are many upsides to fiberglass and only a few downsides.

Cellulose vs Fiberglass Insulation Pros and Cons
Fiberglass Insulation Pros Fiberglass Insulation Cons
Cost effective and low-cost material Doesn’t work effectively when wet and until it has been professionally dried
Helps decrease your energy bill by 40% Improper self installation and handling can lead to health problems
Last up to 100 years in ideal conditions Loses R-value in extreme cold and temperature changes2
Lower risk of it catching fire or developing moisture-related problems Loses R-value when compressed or packed densely2
Excellent noise insulation
R-value between 2.2 and 4.3
Fiberglass batts are less prone to settling
Cellulose Insulation Pros Cellulose Insulation Cons
The cost is 75% lower than fiberglass Needs to be chemically treated to be pest-repellant
Comes in small pieces and easy to install Flammable material and a fire-risk
R-value ranges between 3.2 and 3.5 Settles after installation which decreases its effectiveness
Loses less R-value when compressed2 Ineffective when wet and mold can grow easily
Maintains R-value even in extreme cold2 Creates a lot of excess dust

Advantages of fiberglass include:

  • Cost-Effective and Energy Saver – Not only is fiberglass made up of a relatively low-cost material, but it’s also such an effective insulator that it can help decrease your energy bill by 40%, helping you save money in the long run.
  • Long-Lasting – Fiberglass is extremely durable and can last up to 100 years in ideal conditions. Unlike other insulation materials, it also doesn’t shrink over time.
  • Non-Flammable & Moisture-Resistant – Though fiberglass may look like cotton, it’s primarily made up of glass, which means there’s a much lower risk of it catching fire or developing moisture-related problems in humid weather. 
  • Noise Insulation – Fiberglass is an extremely effective insulator not only when it comes to protecting your home against weather, but also against unwanted noise. Whether you live in a busy part of town with lots of traffic or you’ve got a loud generator right outside, fiberglass insulation can help keep your home a quieter and more peaceful place. 

Disadvantages of fiberglass include:

  • Ineffective When Wet – If your fiberglass becomes significantly wet due to a leak in your attic, the insulation will not be able to work effectively until it has been professionally dried.
  • Self-Installation Can Be Dangerous – Because fiberglass is made up of tiny glass fragments, it can be dangerous to handle it without taking safety precautions and improper handling can lead to health problems like rashes or respiratory damage. That’s why it’s always best to consult an expert or insulation contractor while installing fiberglass insulation.

What is Cellulose Insulation?

Cellulose is another popular form of home insulation. It’s typically made from 82-85% recycled material like newspaper or tiny fragments of wood.2 These are then shredded and fiberized so they’ll be able to pack tightly together and stop the flow of heat. 

While there is only one type of cellulose insulation, there are several different ways to install it:

Old Home Installation (Blown Dry)

For homes with a pre-existing structure, part of the siding will have to be removed, a row of holes will be drilled into the wall, and then insulation can be blown in dry.

New Home Installation

  • Damp-sprayed – Moisture is added to the tip of an insulation spray nozzle, activating the starch in the cellulose. It’s then sprayed over the cavities in your home. 
  • Dry-netting – A net is blown full of dry cellulose and then stapled over openings in the building.

The best method of cellulose insulation installation will depend on what kind of home you have and what tools are available to you.

Pros and Cons of Cellulose 

While there are certain advantages of having a paper-based insulation, there are also some notable disadvantages. 

Advantages of cellulose include:

  • Low-price – Because cellulose is primarily made out of paper, it’s an even more inexpensive form of insulation at about 75% of the cost of fiberglass.
  • Easy Installation – Cellulose comes in small pieces and there are many ways to install it, so it fits well with most homes’ structures but can be very messy to install. 

Disadvantages of fiberglass include:

  • Not Pest Repellant – Since cellulose is not naturally pest repellant, it’s often treated with chemicals like boric acid that claim to ward off rodents and bugs. In reality, boric acid does little to repel rodents, leaving your home vulnerable to a potential infestation. 
  • Naturally Flammable – Cellulose is also treated with chemicals to help make it more flame resistant, but because it’s made of paper, it will always pose more of a fire-risk than a non-flammable insulation material. 
  • Settles After Installation – Cellulose insulation tends to settle by several inches after it’s installed, which causes it to decrease in effectiveness. 
  • Mold Grows When Wet – Like fiberglass, cellulose is ineffective when wet, but unlike fiberglass, it can also be dangerous. The paper base of cellulose provides the perfect environment for mold and mildews to grow and the boric acid used to treat it can become corrosive when in contact with water.
  • Excess Dust – Because cellulose is essentially made up of finely shredded paper, it creates a lot of dust when it’s being installed, which makes it difficult to clean up and can turn it into a breathing hazard for those installing it. 

R-Value: The Role of Thermal Resistance

One of the most important considerations when comparing different types of insulation is R-value. R-value measures the thermal performance or resistance of a material, or in other words, its ability to keep warm places warm and cold places cold.

Materials with a higher R-value will more effectively insulate your home, helping you keep a more regulated temperature indoors and a lower energy bill. 

Different insulation materials have different ways of combating heat flow and therefore different R-values. Fiberglass’ R-value tends to range between 2.2 and 4.3 depending on the density of the material, whereas for cellulose, the R-value ranges between 3.2 and 3.5. 

This means cellulose insulation has a slightly higher average R-value than fiberglass, but high-quality fiberglass provides better thermal resistance than high-quality cellulose. 

Should I Choose Fiberglass or Cellulose Insulation?

While both fiberglass and cellulose insulation have their own benefits and can be useful in different environments, overall, fiberglass has much more advantages as compared to its downsides.

Fiberglass installation is an affordable, easy-to-install form of insulation that is compatible with most homes and protects against a lot of the dangers caused by poor insulation materials.

Because of this, we recommend fiberglass over cellulose for high-quality insulation that will last. And if you haven’t considered blow in insulation vs spray foam, read our recent blog to understand the difference between these two types of insulation, to make the most informed choice for your home.

Attic Insulation & Air Sealing: Should You Do Both?

Picture this: it’s a cold winter morning and you’re leaving for work. You just made some coffee and you want it to stay warm for the drive. What do you do? You pour it into a tumbler and seal it with a lid on top. 

This tumbler keeps your coffee warm much the same way attic insulation and air sealing do for your home. 

The stainless steel interior of the tumbler works like proper insulation, helping to keep heat from escaping or entering through the sides of the cup. The rubber sealing of the lid works like your home’s sealing, keeping out cold air while helping keep the warmth inside from seeping out of any gaps. 

Both insulation and sealing work in their own ways to help maintain a regular internal temperature and they’re essential parts of creating optimum energy efficiency. In this article, we’ll go over the different ways attic air sealing and proper attic insulation help stop the flow of heat and which is more important for keeping your home comfortable. 

What is Attic Insulation?

Insulation works by creating a thermal barrier between your home and the outside world. This barrier helps reflect the weather outside your home and maintain the indoor air quality and temperature inside, so you’re heating and cooling systems won’t have to work as hard to keep your home comfortable. 

However, according to Energy Star, 9 out of 10 homes in the U.S. are underinsulated.1 This means most people are likely overpaying for their energy bills due to their home’s inability to properly regulate temperature. 

The good thing is that existing insulation technology has come a long way in the last few decades and there are many insulation options for homeowners. 

Signs Your Home’s Insulation Needs Updating   

If you aren’t sure whether or not your home is properly insulated, here are some warning signs of poor insulation to look out for: 

  • High energy bills 
  • Drafts indoors
  • Temperature fluctuates from room to room
  • Cold interior walls or floors 
  • Visible joists in the attic 

If your home shows any of these signs, it might be time you had your insulation replaced. 

Types of Insulation

Insulation is not a one-size-fits-all kind of business. It comes in a variety of different materials, each of which works to regulate the temperature in your home differently:2

  • Fiberglass batts – Fiberglass batts may look like big rolls of cotton but they’re actually made of tiny pieces of fiberized glass. These fibers are spun into long blankets for easy installation. 
  • Blown-in Fiberglass – Blown-in fiberglass insulation is made up of the same material as batts, except instead of coming in big rolls, they come in small pieces that are blown into place. They’re popular for being one of the most affordable and effective forms of insulation. 
  • Cellulose – When examining Cellulose vs Fiberglass insulation, Cellulose is made of extremely finely shredded pieces of newspaper that have been fiberized to stick together and block heat flow. It’s a cheap and simple-to-install form of insulation, but it doesn’t survive well in humidity or against pests. It is actually a common misconception and marketing strategy to try and position cellulose as a pest retardant. 
  • Spray Foam – Spray foam insulation provides an airtight seal and is completely waterproof. Unfortunately, it does also come with a higher price tag, is typically used for industrial use only, and can be difficult to install without professional assistance. 

What is Attic Sealing?

Even if your home has high-quality insulation, it may not be enough to keep the temperature in your home regulated. In fact, it’s commonly thought that if you add up all the gaps and leaks in the average home’s envelope, it would be the equivalent of leaving a window open all year.3

So how can you tell if your home has a sealing problem?

Oftentimes, the signs of poor attic air sealing are similar to those of poor insulation—drafty rooms, high energy bills, uneven room temperatures—so it can be difficult to tell whether the problem you have is because of bad insulation or sealing. 

To determine the root cause, you may need to do some investigation.

Identifying the Source of Your Air Sealing Problem

Most of your air sealing problems are going to come from the parts in your home where there are natural gaps, such as where walls meet or where pipes disrupt the structure of your home.4 

There are a number of different tests you can do to figure out if you have a gap in one of these areas.

Visual Inspection

The simplest way to find significant gaps in your home’s sealing is by conducting a visual inspection of places where sealing problems commonly occur, including:5 

  • Kneewalls 
  • Soffits
  • Door and window frames
  • Plumping, wiring, and pipes 
  • Chimneys or furnaces
  • Baseboards
  • Switchplates
  • Attic hatch 

If you notice a hole in any of these places, make a note of it and come back later to seal it. 

The Light Test 

If you’re not sure where to look for gaps in your home’s sealing, the light method can be incredibly helpful. Simply turn on light fixtures in a room where you suspect there’s a leak and observe from the outside where the light shines through. Wherever you see the light shining is a place that needs to be sealed. 

The Paper Test  

If you specifically want to see how energy efficient your outside-facing doors and windows are, you can use the paper test. All you need to do is shut your window or door on a piece of paper and then try to pull it out. If the paper comes out all in one piece, the door or window will need to be properly sealed. 

The Smoke Test  

For air leaks that are difficult to locate, you can try a smoke test. Here’s the procedure:

  1. Wait for a day when the outside weather is cool and windy.
  2. Turn off all combustion appliances and block off all exterior-facing windows, doors, and chimneys.
  3. Turn on all exhaust fans that blow air outside.
  4. Light an incense stick or sprinkle talcum powder in the air around the edges of the room. Where you see the smoke or powder moving out of the room, there’s a leak that will need to be sealed up. 

How to Seal Gaps in Your Home’s Envelope

After you identify where the leaks in your home’s sealing are coming from, there are a few steps you can take to mitigate the problems, including: 

  • For large gaps, like those around knee walls and soffits: Using proper protective gear, fill a garbage bag full of fiberglass insulation and stuff it into open cavities until the bags fit tightly. Follow Attic Construction’s guide for a full breakdown on fiberglass insulation cost. 
  • For heat-sensitive areas, like those around chimneys and water heaters: Seal gaps with lightweight aluminum foil, making sure to leave a metal dam between the area and any potentially flammable insulation.
  • For smaller holes, like those around plumbing and wires: Use an expanding foam or caulk to fill up cavities.

Always make sure you’re performing these insulation fixes safely, using the proper protective gear. If you have any questions, reach out to the experts at Attic Construction.

Attic Insulation vs Air Sealing: Which Is More Important?

Both insulation and sealing work together to regulate the temperature of your home, but which is more important when it comes to keeping energy costs in your home down? 

To answer that question, we’re going to revisit our tumbler analogy from earlier. 

Let’s say you were to take your hot coffee with you to work in a non-insulated container, like a mug or paper cup. Since there’s no insulation to keep the heat of your drink from leaking out the sides, where it is surrounded by winter air, your drink will quickly lose heat and will likely be cold by the time you arrive at work.  

If, on the other hand, you were to bring your drink to work in an insulated tumbler without the lid, your drink will still cool down while you drive but at a much slower rate, so your drink will likely still be warm enough to drink by the time you arrive at the office. 

The reason for this is insulation does a lot more work to regulate temperature than sealing does as it covers more surface area in your home. As long as the gaps in your home aren’t major and clearly visible from the outside, having high-quality insulation is going to be a more essential part of keeping your home’s temperature regulated and your energy bill down.

Breaking Down Attic Insulation Removal Cost

Older homes offer significant benefits—vintage architecture, affordable cost, and a rich history behind them. The one thing you may not love about your older home? The existing insulation.

Your home’s insulation is a vital aspect to proper temperature control and energy efficiency. If you’ve noticed that your attic space is particularly drafty in the cooler months, but feels like a sauna in the summer, it may be time to remove and replace the old insulation. 

While this can sound intimidating, it’s actually a very routine part of home ownership.

Before jumping into this project, you probably want a general idea of what the bill is going to run you. Continue reading for a full breakdown of attic insulation removal costs.

How Does Insulation Removal Work?

In order to determine a cost estimate, it’s important to understand what this process entails. Though every home is going to have a unique situation, most insulation removals will follow these four steps:

  • Preparation – Preparation is key to a successful removal and long-lasting replacement. The cost of your insulation removal is going to partially depend on how much prep work must be done before the job can even begin. The preparation procedures will correlate to how damaged or infested your current insulation is—since many older homes can have contamination and rodent infestations in these areas.
  • Removal – Depending on the type of insulation you’re dealing with, such as fiberglass batt insulation, foam insulation, or batt insulation, the removal process can vary. For contaminated blown-in insulation, a vacuum device is used to carry the material out of your home in a safe, contained manner. This may be cheaper than the removal of batt insulation, which is rolled up by hand and taken away. Your cost of removal will ultimately depend on
  • How much old attic insulation is currently in place
  • Levels of the contaminated insulation, mold and moisture
  • The amount of labor needed to get the job done
  • Replacement – Once your old insulation is removed, it will need to be replaced as soon as possible. Pricing of the replacement process will depend on several factors:
  • How much insulation is used
  • The R-value of the materials
  • Any rodent-proofing procedures needed
  • Decontamination measures
  • Clearing of debris from the area

The Bottom Line – The process of insulation removal can be complicated. Each step will have its own specifics that may affect the overall price. Time, tools, and level of contamination are the biggest factors to consider when determining cost. 

The Relationship Between Price and R-Value

Replacement is a big part of insulation removal, and typically you’ll want everything done at once to keep your home properly temperature controlled. This means that you’ll have to take the type of insulation and its R-value into consideration when estimating your final cost.

If you’re not an expert on attic insulation, you may be wondering what exactly is R-value. The answer isn’t too complicated. 

R-value is a unit used to measure insulation performance.

In the United States, different areas fall into R-value categories. Depending on the climate, each region is numbered 1-7 (1 being the warmest, 7 being the coldest). Once you know which category your home falls in, you can find the proper R-value needed to insulate your attic by using the chart below:

  • Zone 1 – R-value should be between R30 and R49.
  • Zone 2 – R-value should be between R30 and R60.
  • Zone 3 – R-value should be between R30 and R60 (California is in this zone).
  • Zone 4 – R-value should be between R38 and R60.
  • Zone 5 – R-value should be between R49 and R60.
  • Zone 6 – R-value should be between R49 and R60.
  • Zone 7 – R-value should be between R49 and R60.

Finding your specific R-value is where things get a little complicated. Every type of insulation is going to come with a different R-value per inch of insulation. 

With that in mind, the general metric used to determine R-value is: ft.°F. h/BTU. 

The Bottom Line – Not too complicated, right? All you really need to understand is this: the higher the R-value, the better the insulation (and subsequently, the higher the cost).

How Do Types of Insulation Differ in Cost?

When it comes to pricing, the type of insulation you go with is going to make a difference. For a  general idea, here’s the rundown on different forms of insulation, and how their costs coincide with quality.

  • Batt and roll – This type of insulation is typically going to work best for the standard home. Batt and roll insulation is usually made of fiberglass, which is a flexible, sturdy, and easy to install material. Fiberglass batts and rolls fit nicely in the beams of unfinished walls and floors, making them the perfect choice for attics. The cost for installing batt insulation is higher as it is more involved.
  • Blow-in or loose-fill – Blow-in or loose-fill insulation is commonly recommended for older homes. This is because old attics tend to have more obstructions and structural inconsistencies, which can make laying down batts and rolls difficult. Blow-in insulation requires specific machinery to fill in gaps, but is typically more affordable than batting insulation.
  • Cellulose – This type of insulation is typically cheaper, but there’s a reason why. Cellulose is made from shredded newspaper, making it particularly dusty and hard to work with. While regular cellulose insulation is cheap, a densely-packed installation is going to cost more. This method is often done because cellulose tends to settle after installation, causing it to lose its original thickness and leave your home more vulnerable to outside temperatures. Cellulose also cannot be turned into batts or rolls, making it a more complicated installation process.

The Bottom Line – Every insulation material has a unique pricing and R-value. Fiberglass batts and rolls are typically a good, cost-effective option, though older homes may require blow-in due to their structure. Cellulose can be a cheaper alternative, but it’s likely to deteriorate faster and leave a bigger mess.

What Is The Average Price For Attic Insulation Removal?

Keeping variables in mind, there are some general ranges you can expect the final bill to fall between. Pricing will typically be broken up into these four categories:

  • Square footage
  • R-value of new insulation
  • Type of materials and tools used
  • Labor (hours worked and employees needed)

Your attic insulation costs will most likely increase when labor and additional materials are tacked on, as well. Labor will typically cost a few hundred dollars, though the size of your attic and the number of workers needed can affect this number. 

The Bottom Line – It’s important to keep in mind that these numbers are averages. Each attic is different and has its own unique situation. Getting a consultation is the best way to determine what insulation removal is going to cost you, since every job will be slightly different. 

Attic Insulation Removal: The Main Takeaway

While averages can help you get an idea of cost, every insulation removal service is going to be different. Variables such as square footage, materials, and contamination can affect your total once the job is complete.

Removing old insulation may be pricey, but the benefits will save you money in the long run. Energy costs when heating and cooling your home will drop significantly if you have proper insulation, particularly in vulnerable areas like your attic. Old insulation can also pose health risks, due to rodent infestation and other contaminants that you may not be aware of. 

It’s always best to schedule an inspection prior to making changes to your insulation. A professional will be able to determine exactly what work needs to be done to ensure your home is safe, clean, and protected from the elements.

Tips For Removing Attic Insulation By Hand

Removing your attic’s old insulation is a task many homeowners face at some point. After a while, the materials used to insulate your home can begin to lose their effectiveness. From normal wear and tear, to more serious issues like vermin and contamination—a lot can go wrong in this vulnerable area of your home so you may want to consider attic insulation removal.

If you’re considering an insulation removal by hand, you have the option of doing the job yourself or hiring a trained professional. 

For the differences between these two methods (and everything else you should know about the process) continue reading for some helpful tips on removing attic insulation by hand!

Types of Insulation

Understanding the type of insulation material you have will determine whether or not removal by hand  is possible. Depending on its material and structure, your current insulation will most likely fall into one of these two categories:

  • Insulation that can be removed by hand – Batt and roll insulation—also known as insulation blankets—are strips of insulated material that are shaped to fit between the slats and boards of your home. This is the only type of insulation that can be removed by hand, due to its rigid structure.
  • Insulation that can’t be removed by hand – Some types of insulation that fall into this category include blown-in foam insulation, loose fill fiberglass insulation, and cellulose insulation. Due to the scattered structure of these insulation types, they cannot be efficiently disposed of by hand. Instead, an industrial hose is used to suck up these materials and leave a clean slate for new insulation to be installed.

Can You Remove Batt Insulation Yourself?

The short answer is yes—batts are typically the only type of insulation that homeowners can realistically remove themselves. With that being said, it’s still recommended that most people hire a professional to clear out any type of older insulation.

Why is this? There are a few different reasons that make professional services more beneficial than a DIY removal. Some of the biggest concerns include:

  • Safety – Removing insulation isn’t a risk-free job. Mold, vermin, and hazardous structures can all pose threats to homeowners attempting this task on their own. With a professional, you’ll have the comfort of knowing your home is in good hands. Plus, you won’t risk being exposed to a rodent infestation, unhealthy air quality, or falling through a loose floorboard (yikes!).
  • Better tools – When you remove batt insulation by hand, there’s usually some debris leftover. If your old insulation was contaminated by mold or pests, any remains can be potentially harmful if they aren’t taken care of. A professional removal company will have the tools needed to fully clean up the area—such as a professional vacuum, decontaminating chemicals, rodent-proofing methods and proper trash bags for removing your old attic insulation. 
  • Replacement – If you’re removing your old insulation, it likely was too old or wasn’t the best material for the space. Hiring a professional to remove your existing insulation will allow for a proper inspection of the situation, and give you the option to install a higher quality replacement.

How to Remove Insulation By Hand

Whether you’re determined to brave this task alone, or you’re considering professional help—you may be curious to know how insulation removal is done. 

Removing batt insulation by hand will commonly require a three step process:

  • Preparation – Before your removal can even begin, you’ll want to take some precautions within the attic space. Clear any furniture and other boxes from your attic. This will help create space and avoid any unnecessary damage or contamination of items.
  • Rolling – Batt insulation will typically be rolled up piece by piece and disposed of in secure bags. If you have contaminated insulation in any way, you’ll want to avoid any contact with your skin. Wearing a mask may also reduce the risk of toxic air entering your lungs.
  • Vacuuming – Any leftover debris can be vacuumed up at the end of the process. An industrial hose (similar to those used for blown-in insulation) will be brought in by professionals to ensure the area is completely clear at the end of the job. This step may be difficult for those removing their insulation themselves if they don’t have the proper equipment.

Get The Job Done Right with Attic Construction

While batt insulation can be removed by hand, that doesn’t make it any easy feat. Thoroughly clearing your attic of old insulation will be difficult without the right tools. You may also want some of the additional services a professional can offer you, like rodent proofing, decontaminating, and attic cleaning services.

Removing Blown In Insulation From Attic: How It Works

So you’re looking to remove your old blown in insulation. This is a decision many homeowners make each year, particularly those living in older houses. Leaving old attic insulation in your home can lead to drafty winters, hot summers, and even pose safety risks in certain situations, and can even disturb the indoor air quality. Not many look forward to removing attic insulation, but it’s worth considering, especially if the current insulation has been there for a long time.

While batting insulation can be rolled up and taken away, blown in—also known as loose fill—insulation is a bit trickier to remove. The job can be done, however, as long as you have the proper equipment, a professional insulation removal team, and take all the necessary safety precautions.

If you’re interested in this process, but want to learn more about it, read on for everything you need to know about removing blown in insulation.

Why Remove Your Blown In Insulation?

Before you commit to a damaged insulation removal, you may be curious about the benefits that come along with this process.

When insulation is past its prime, its effectiveness and safety are significantly reduced. Some of the biggest reasons homeowners choose to remove their old attic insulation include:

  • Lower energy bills – When damaged insulation isn’t working to its full capacity, it can cost you a pretty penny in utility bills. This is because proper insulation makes heating and cooling your home much easier and more affordable. When there are gaps in your insulation, outdoor air is able to seep through the walls and affect the temperature inside. It’s no surprise that cranking the heat in the winter and air conditioner in the summer isn’t doing any favors for your wallet. That’s why paying for the removal of old insulation, and installing something more effective will ultimately save you money in the long run and provide better home efficiency.
  • Rodents – Old insulation can pose safety risks when pests are involved. Rodents often burrow into the insulation of older homes, particularly in areas with little traffic—like attics. Additionally, a few rodents can quickly turn into a rodent infestation. Removing infested insulation and replacing it with something more hygienic will prevent these pests from spreading disease and other germs throughout your home.
  • Contamination – In addition to rodents, it’s possible for other contaminants to live inside your insulation, as well. Some of the most common infestations found in blown in insulation are mold and mildew. Contaminated insulation can cause unhealthy indoor air quality throughout your home, and put you at higher risk of leaks and water damage.

Attic insulation removal cost can also be high but it might make a significant difference in your health and your home. The main idea – Removing blown in insulation has quite a few benefits. Ridding your home of worn–out or contaminated insulation can improve your energy bills, clear out pests, and improve air quality.

When Should Blown In Insulation Be Replaced?

Understanding when an attic insulation removal is necessary can be tricky. It’s important to know which key warning signs to look for when examining your insulation, such as:

  • Holes – If you’ve noticed bare spots where your blown in insulation is missing, this is a clear indicator that it needs to be removed and replaced. When your insulation has holes, outside air has a clear entryway to your home, leading to uncomfortable temperature shifts.
  • Moldy spots – When visible mold is growing on the surface of your insulation, it’s time to start fresh. Mold spots may be black, brown, or gray depending on the types of mold or fungi and the severity of the outbreak. Any color inconsistencies are generally a bad sign when it comes to insulation.
  • Droppings – The presence of rodent droppings around insulated areas will be one of the biggest indicators of a pest infestation. Chewed-up areas can also signal that vermin are living among the insulation. Knowing how to find rodent entry points is important to properly insulate those areas and prevent infestations.
  • Temperature – If your home is drafty, hot, or generally uneven in terms of temperature, this may be a sign that your insulation isn’t working properly. Certain parts of your home should not be warmer or cooler than others when insulation is distributed evenly.
  • Color – In addition to discolored spots, the overall hue of your insulation can suggest what condition it’s in. If the bright pink or white color of the material has become pale and dusty looking, this may mean it’s time for a replacement.
  • Leaks – Leaks or moisture in your ceiling can be a sign of damage to insulation, particularly in the attic.

The main idea – There will be many visible signs when your insulation needs replacing, such as dark spots, holes, and faded color. Leaks and temperature inconsistencies in your home may also be related to insulation issues. If you have a rodent problem, insulation is one of the most common places these pests like to hide, which may be another reason for insulation removal.

How Does Removing Blown In Insulation Work?

Now that you understand why you should remove your old blown in insulation, it’s time to learn how this removal is done. The process can be completed in three basic steps

  • Preparation – Preparing the area is crucial to a smooth removal job. These removals can be messy, and having the proper precautions in place will help to keep the rest of your home clean and sanitary when disposing of old insulation. Some preparation steps that your removers will take may include:
  • Laying down plastic sheeting
  • Moving furniture and other personal belongings out of the area
  • Setting up a secure vacuum outside of the home
  • Vacuum removal – Since blown in insulation cannot be removed by hand, a 23 horsepower vacuum is needed to dispose of the old materials. Once the vacuum is stationed in a safe place outside your home, a 6-inch diameter hose is attached and brought into the insulated space. From there, your technicians will begin vacuuming out all the old insulation, including any debris that scatters during the process. The old material will travel through the secure hose and be deposited into insulation removal bags, without tracking any contamination throughout the rest of your home. This process is secure, safe, and hygienic when done correctly by trained insulation professionals.
  • Replacement installation – Once the old insulation is removed, you’ll typically want a replacement installed shortly after. Along with new insulation, you also have the option to get your area rodent proofed and have any entry points sealed off. In terms of replacement, there are two main options for your new insulation:
  • Blown in – For older homes with obstructions and structural inconsistencies, new blown in insulation will typically be recommended for maximum coverage. Using fiberglass insulation will help your replacement last longer than other materials-like a cellulose insulation.
  • Batts and rolls – If your space is composed of relatively normal slats and boards, you may want to switch to batt and roll insulation instead Keep in mind that  installing batts and rolls tends to be more expensive and labor intensive. 

The main idea – Removing your old blown insulation is a three-step process. First the area must be prepped. A vacuum is then used to remove all the old insulation materials. Finally, you have the option to get new insulation installed.

Why Should You Get New Insulation Installed After Removal?

Just as old insulation can pose a threat to your home, having no insulation at all is equally risky. Though old insulation removal will eradicate any pest and mold infestations, temperature issues can only be resolved with the proper replacement of insulation materials.

With no insulation in your walls or attic space, you may run into problems such as:

  • Extreme temperatures indoors
  • Reduced value of your home
  • Increased noise pollution
  • Wasted energy usage 

Taking care of your home’s inner mechanisms is crucial to maintaining its equity, as well as your own personal comfort. Rather than waiting to get a replacement down the line, it’s best to have new insulation installed immediately after removal.

The main idea – Simply removing your old insulation is not a complete fix. Installing a new, high quality replacement will be a necessary next step to take after removal is complete.

Out With the Old, In With the New: Removing Blown In Insulation In a Nutshell

If you live in an older home, it may be time to remove your old blown in insulation material. A proper replacement will help lower utility bills, retain the value of your property, and keep you and your family comfortable all year round.

comfortable all year round.

When left untreated, contaminated insulation can also pose health risks, such as rodent infestations and mold outbreaks. If you suspect your home has fallen victim to either of these issues,  insulation removal should be scheduled as soon as possible. Rodent proofing and attic cleaning services can also be added to your replacement installation if desired. These services will help keep your home protected from these pests in the future.

hen it comes time to remove the old existing insulation, it’s best to get the help of an insulation removal service to ensure it’s being done properly and safely. The same goes for hiring an insulation service or professional for insulation installation.

How To Remove Batt Insulation

Have you inspected the insulated areas of your home recently?

For those who live in older homes, you may want to consider taking a look at your attic or crawl space—or hiring a professional to do so. Insulation can only last so long, and after several decades it may become worn out, torn, or even contaminated. Removing old insulation is the best way to start fresh and improve the temperature and air quality within your home.

But how does it work? 

Some people choose to remove their old attic insulation themselves, but this can be a difficult process that may pose safety risks to those who are untrained. For more information about how a professional will perform this job, read on for everything you need to know about how to remove batt insulation.

What is Batt Insulation?

Depending on the type of insulation material you currently have, the removal process is going to look a bit different.

The most common form of insulation is called fiberglass batt insulation. Batt insulation is typically made from fiberglass or mineral wool. This material is cut into strips that fit perfectly between the slats and boards of standard homes, particularly in walls and attics.

Batt insulation is different from blown in insulation because it’s installed piece by piece. Blown in insulation will typically require an industrial hose to spray the material into more misshapen areas. The same logic is applied to each type of insulation’s removal process, as well.

How is Batt Insulation Removed?

The professional removal of batt insulation will typically require three steps:

  • Preparation – Be sure to prepare your attic space before insulation removal. All furniture and personal belongings must be stored elsewhere until the process is complete. Laying down plastic sheeting in and around the area is another step that will keep your home safe and clean while removing the insulation.
  • Hand removal – The next step is a very important and difficult labor task, which is removing batt insulation by rolling up each individual piece by hand. The blankets are then transported out of the home in secure disposal or garbage bags.
  • Vacuum – Finally, a vacuum is used to clear up any debris that was scattered during the removal process. This step must be thoroughly performed to ensure no leftover materials contaminate or compromise the new insulation once it’s installed.

Following the removal process, you’ll want to have new insulation installed as soon as possible. Without proper insulation, you run the risk of extreme temperatures, draftiness, and higher utility bills in your home. 

Why Should You Hire a Professional to Remove Your Insulation?

Although it’s possible to remove batt insulation yourself, there are benefits that come with hiring a professional to do the job. Insulation removal can be a difficult process, and opting to DIY this task will pose several risks:

  • Contamination – Older existing insulation may be contaminated with mold or mildew if moisture has found its way into the area. Safely disposing of this contaminated material can be tricky without the proper equipment. If you see discoloration on the surface of your insulation, it’s best to call a professional to remove it so you don’t risk breathing in anything dangerous.
  • Pests – Another health risk when removing old insulation is pests. Rodents often borrow into the insulation of older homes, and dealing with them should not be taken lately as it can quickly turn into a rodent infestation. Additionally, these vermin can potentially spread disease to you and your family. A professional removal company will have the proper rodent proofing materials to decontaminate the space and prevent any future infestations.
  • Risk of falling – Many attics lack the proper support needed to walk around freely. When you choose to remove insulation yourself, you run the risk of falling through crevices and getting hurt. A team of professionals will be able to set up a safe workplace and avoid any accidents while on the job.

Removing your own batt insulation comes with many risks. If you’re hiring professionals to install the new insulation, it may be the best choice to opt for removal services as well, as this will ensure the job is done correctly and safely. 

Professional removal will also be the best choice when it comes to contamination concerns, which can be difficult to handle without the proper know-how.

Is There Too Much Insulation in Your Attic?

Is There Too Much Insulation in Your Attic?

For many homeowners, ensuring their attic space is well-insulated is one of the most cost-effective ways to maximize their home’s energy efficiency. No matter what insulation type you use, proper attic insulation should have the optimal R-value based on your location and home requirements. Whether you use blanket insulation, fiberglass insulation, spray foam insulation, or cellulose insulation, the goal is to achieve the proper depth and ideal R-value for your attic space.

But can you over insulate your attic? Could your existing insulation be too much? While over-insulated attics aren’t as common as under-insulated attics, it is possible to put so much insulation in your attic that it has a negative impact.

To understand why this is the case, we’ll take a closer look at how your attic is supposed to function, why attic insulation is crucial for your home’s energy efficiency and comfort, and how much is too much insulation in your attic. 

How are Attics Supposed to Work?

Before diving into why over insulating is possible, it’s worthwhile to take a brief detour to learn how attics are supposed to work. This explains why over insulating can cause problems. There are two types of attic construction methods; vented and unvented. Understanding which you have has important implications for how and where you insulate.

Vented Attics

Vented attics are the most common type of attic construction. In a vented attic, insulation is placed along the ceiling plane of your home. This leaves the actual attic space above your home’s insulated areas, known as the conditioned space. 

As the name would suggest, vented attics have vents located around the eves of the roof. These vents allow the air in your attic to circulate with the outside air passively. This is important for two reasons. During the winter, those vents allow cold air from the outside to cool down the attic, which keeps the roof cool. If you have snow on your roof and the air in your attic is warm, the snow can melt off your roof and refreeze in your gutters, known as an ice dam.

During the summer, attic ventilation allows excess moisture to rise from your home’s interior and hot air in the attic to vent outside. This has the added benefit of protecting your roof shingles from damage. 

Sealed Attics

A sealed or unvented attic has the insulation installed at the roof rather than the ceiling plane, bringing the attic space into the home’s conditioned area. Unvented attics are less common than vented attics, but they do offer some advantages.

Sealed attics are considered more energy efficient than vented attics. This is partially due to the fact that air-conditioned ducting is brought into the conditioned space of your home, offsetting the energy loss that occurs from leaky ducts.

One thing to note about unvented or sealed attics is that they lack the protection against heat buildup for shingle roofs that vented attics offer. Because of this, some homes with sealed attics utilize a double roof that features a ventilated air space above the insulated roof decking.

Why Is Insulation Important?

Using the right amount of insulation can make your home feel more comfortable and can save you money on your energy bill. Insulation is important because it helps reduce the transfer of heat from the conditioned spaces of your home to the unconditioned outside. This means that your home’s warm air will escape more slowly when running a heater in cold weather. When you are running your air conditioning unit on a hot day in the summer months, your home will stay cooler longer.

The relationship between the transfer of heat and insulation can be found in an insulation’s R-value. The R-value is a rating used to note an insulation material’s thermal resistance, or how well that material resists the heat transfer, per inch of insulation material. Heat transfer is inevitable, but insulative materials slow the process down.

The effect of a well-insulated attic space is greater energy efficiency and comfort. A home with a poorly insulated attic will experience more significant fluctuations in temperature throughout the day. So, in a poorly insulated home on a hot day, the home’s conditioned spaces’ temperature will have a wider range than in a well-insulated home. Because of this, if you’re running your air conditioning, your air conditioner will have to work harder to keep your home’s conditioned areas the same temperature throughout the day. Not only is a well-insulated attic important, but also making sure your attic is safe and free of asbestos attic insulation. 

How Much Insulation is Too Much?

In Southern California, you’ll want to shoot for an R-Value of around 30 for an optimum experience. The California Department of Energy’s 2019 Building Envelope requirements state the minimum R-Value for wood-construction ventilated attic spaces in California is R-22. In contrast, the Environmental Protection Agency’s (EPA) Energy Start program recommends an R-Value between 25 – 38 for homes in Zone 3, encompassing most Southern California areas.

Achieving an R-Value of 30 should offer more than sufficient insulation in the Southern California area, without some of the downsides that come with too much insulation in the attic.

While achieving an R-Value of 30 is optimum, anything over an R-Value of 38 is probably excessive. Here are a couple of reasons why more insulation isn’t necessarily better:

Poor Return on Investment

Return on investment (ROI) is a concept often heard in business for determining the efficiency of an investment. In the context of insulation, determining your return on investment comes down to dividing the benefit it will provide you, namely your energy savings over time, by the cost of the initial investment.

Put simply, achieving an insulation R-Value over 38 in your attic, in Southern California, offers a poor ROI. What you may gain in efficiency is more than offset by the cost of investment into the additional insulation.

If you have attic insulation with an R-Value of 38 and still want to make your home more energy efficient, consider installing a radiant barrier instead. Radiant barriers are great because they block heat from your roof before it can ever reach your insulation. That means less heat will transfer into your home’s conditioned spaces, which will allow your air conditioning system to cool your home more efficiently. 

Poor Ventilation

Ventilated attics need to ventilate. If you’ve got four feet of insulation stacked throughout your attic, it could be impacting how efficiently your attic can circulate air. Ultimately, though, it really depends on the type of insulation material you have in your attic. If you are uncertain about what to do, you may want to look into a professional inspection and replacing attic insulation.

As we mentioned, air circulation is a crucial feature of ventilated attics. That passive air circulation occurs through the vents from your attic to the outside that are located underneath your eaves. 

Blocked vents in a vented attic will lead to poor energy efficiency, moisture buildup in your attic space, and most importantly, it will lead to mold. This is a big issue and may require hiring an attic insulation removal service  to prevent further damage and potential health concerns. 

Better Results Through Proper Installation

If you want the best result from your new attic insulation, focus your attention on how it is installed. Well-installed attic insulation with an R-Value of 30 will always perform better than poorly installed attic insulation with an R-Value of 38. 

Well-installed attic insulation will eliminate air gaps between the insulation and a structural component or between insulation pieces. An air leak can significantly impact your insulation’s performance and lead to moisture problems down the road. As warm, moist air rises from your home’s conditioned spaces, it will escape more easily through that area if an air gap exists. This will lead to the formation of condensation and eventually lead to moisture damage.

A well-insulated attic will have comprehensive coverage of your chosen insulation and be clean and dry. The use of a radiant barrier is also a great idea, as that will reduce the transfer of heat between the roof and insulation. 

Closing Thoughts

Can you over insulate your attic? The answer is yes! Past a certain point, insulation in a vented attic will do more harm than good. In most of the United States, achieving an R-Value of 38 is more than sufficient. In the temperate Southern California region, an R-Value of 30 tends to be ideal. 

Using more insulation than required doesn’t offer a significant advantage and can detrimentally affect how well your attic ventilates. If you’ve got well-installed attic insulation of a sufficient R-Value and still aren’t pleased with the results, you may want to consider installing a radiant barrier. Radiant barriers are a great way to maximize the benefit you realize from your attic insulation and improve your home’s energy efficiency.

Replacing Attic Insulation 101

If you live in an older home or are experiencing some of the issues we’ll outline below, you may want to consider replacing your attic insulation. For homes with insufficient or damaged insulation, replacing attic insulation can restore energy efficiency and comfort.

Understanding the top signs that it’s time to replace your attic insulation, and what benefits new attic insulation can bring, is often helpful information for homeowners deciding whether this project is right for their home. From a house that is too drafty to energy bills that are steadily creeping higher, you’ll definitely want to keep an eye out for these top signs that attic insulation replacement may be needed.

#1. Rodents in Your Attic

Few things can be as destructive to an attic space as a rodent infestation. Rodents love attics because they’re protected from the elements making them warm and dry, sheltered from predators, and have lots of great nesting materials in the form of insulation or stored belongings.

If you suspect you have a rodent infestation in your attic, don’t wait to deal with it. The longer a rodent infestation is allowed to occur in an attic, the more pervasive and extensive the damage is. 

Signs of a rodent infestation in your attic include:

  • Odd smells coming from your attic space.
  • Scratching or scurrying sounds in your ceiling.
  • Pets paying close attention to your ceiling or walls.
  • Nesting materials in your attic (shredded cardboard, piled and disturbed insulation).
  • Rodent droppings in your attic.
  • Damaged insulation or belongings.

If you’re facing a rodent infestation in your attic, there are three basic steps to fixing it. These are:

  • Rodent proof your attic by sealing off any possible entrances. Be mindful that mice can enter a space as small as a dime.
  • Remediate any existing rodent damage. This includes removing contaminated insulation, disinfecting the attic space, and reinsulating.

If you do suspect you have a rodent infestation, you may want to leave it to the professionals to deal with. Great care must be taken when cleaning up after a rodent infestation, as rodent urine and feces can carry communicable diseases. This is also one of the primary reasons you want to address a rodent infestation when you suspect it, since rodents in your attic actually affect the air quality throughout your home. 

Approach a possible rodent infestation with caution, and be proactive if you find that you are dealing with one.

#2. Mold Growth

If you see mold growth on the insulation material in your attic or surrounding surfaces, such as the framing around the ceiling plane, you’ll definitely need to consider attic insulation removal and replacement.

Mold grows where moisture occurs. Without moisture, mold won’t grow. Mold growth on surfaces in your home is especially bad since it can impact the air quality throughout your home, as well as the durability of your home. 

The growth of mold in your attic is a sign of two things:

  • Your attic insulation needs to be replaced and any mold damage needs to be remediated.
  • The source of the moisture causing the mold needs to be tracked down and addressed.

Putting new insulation down won’t solve your moisture issues. After the old insulation is removed you may need to air seal your attic space. This helps with moisture issues because moisture in attic spaces often occurs in gaps between insulation. These small gaps allow moist, warm air from the conditioned spaces of your home to easily travel up through the air gap. As it moves upward and cools the moisture forms condensation, which builds up and over time will result in mold.

If you aren’t sure where the source of your moisture problems is, be sure to have your attic professionally inspected before putting down new insulation. Without addressing the root issue causing the moisture, you’ll just be back up in your attic dealing with more mold within a short period of time.

#3. Your Home is Old

If you have an old home and have never replaced your attic insulation, it may be time. Though most common types of attic insulation used today are rated for very long life spans, that’s assuming that it is kept in clean, dry conditions. Older homes also have older insulation types, which may not offer sufficient or adequate thermal resistance for your home’s needs.

If you do have an old home, it may be worthwhile to take a quick peek at what type of insulation you have in your attic. Visually inspecting your attic space can tell you a lot of things, such as how clean or dirty the space is, what physical condition your insulation is in, and even what type of insulation you have.

Pay very close attention to whether you have vermiculite insulation. Vermiculite insulation appears like small pebbles, usually grey-brown or silver-gold in color. If you do see vermiculite insulation placed in between the ceiling joists, do not disturb it. Leave your attic space and contact a professional to have your attic inspected for asbestos.

While asbestos isn’t in most insulations, vermiculite insulation made with vermiculite mined in Libby, Montana may contain asbestos and should be treated as such. If you suspect your attic insulation contains asbestos, don’t try to remove it yourself. Limit access to the area and have the potentially contaminated insulation professionally inspected by someone trained and certified for working with asbestos attic insulation.

#4. Your Insulation is Dusty or Dirty

You may not realize it, but the quality of the air in your attic can have a big impact on the air quality throughout your home. Over time, vented attic spaces can get covered with a layer of dust and debris blown in from the outside. That dust will settle onto everything, including your insulation. 

While dust may seem like a pesky nuisance around your home, the dust accumulated in your attic can actually contain contaminants. Specifically, attic dust has been shown to contain environmental contaminants that can date back to when your home was built. Environmental contaminants may include heavy metals, which can be harmful for your health if inhaled. 

Your attic insulation can capture and retain those contaminants, even if you’ve made an effort to clean the rest of your attic. For older homes with dusty or dirty insulation, it’s probably time to consider thoroughly cleaning your attic and replacing the existing insulation. To minimize the health risks of doing so, we recommend having your dirty attic insulation removed and your attic space cleaned by professionals like our team at Attic Construction.

#5. Leaky or Water Damaged Roof

Every homeowner knows that a leaky roof can cause big problems, and needs to be addressed. What you may not realize is that if you have a leaky roof, you’ll probably also need to change your attic insulation. This is because water penetrating your leaky roofing could affect the attic insulation underneath it.

Wet attic insulation is a poor insulator. While some types of insulation, such as fiberglass batt insulation, retain more of their insulative properties when wet than others like cellulose insulation, it’s only a matter of time before your wet insulation becomes moldy insulation. Wet insulation can also transfer moisture to the adjacent framing and building materials, potentially spreading mold growth and deteriorating the integrity of your framing materials.

As a best practice, if you find a leak in your roof have the attic insulation in that area professionally inspected. If the leak has been occurring for some time without being caught, you’ll most likely need to replace the attic insulation and remediate any water damage that occurred.

#6. Insulation Was Moved or Compromised

Sometimes, insulation can be moved or compromised when repairing it, and may not be put back into place. As a result, you may have areas that are not sufficiently insulated. If you notice that the temperature inside your home fluctuates more than it should, it can be an indicator that your insulation was shifted or compromised. As a result, your HVAC system will have to work harder to heat or cool your home, which can impact your energy bills. 

 If your insulation is moved and there is a gap in the insulation, this is another opportunity for mold. Warm air flows to the gaps in insulation and when air is moving in and out of the house, water will condense and feed the mold.
