Attic Insulation Removal: What Goes into the Process?

Written by Kevin on October 14, 2021. Posted in Attic Insulation, Insulation removal. No Comments on Attic Insulation Removal: What Goes into the Process?

If you can’t recall when your attic insulation was installed or augmented, it may be time to consider removal. Insulation can often be supplemented rather than replaced, but removal is a must if there are signs of water damage, mold, or infestations. Additionally, older insulation and insulation that’s dirty, damaged, or past the end of its life expectancy may need to be replaced. Not only will this help improve the energy efficiency of your home, but it will also reduce utility bills as well.

While you can remove your attic insulation yourself, it may pose risks to your and your family’s health. A team of skilled professionals can remove existing insulation in a single day and is able to accurately gauge dangers and weaknesses in your attic environment.

Let’s take a look at the stages of attic insulation removal, starting with figuring out what type of insulation you have and what condition it’s in.

1. Identifying Your Insulation

Not exactly sure what type of insulation is keeping your house temperature regulated? With a quick visual inspection, you can usually determine what kind of insulation you have. You may also be able to tell whether you need to add additional insulation or if it has tell-tale signs of needing removal and replacement.

To plan attic insulation removal, you need to consider both its format and its base material. Common types of attic insulation are:

Batt and roll – Often pink or gray, batting insulation is also known as blanket insulation. It’s created from flexible fibers formed into layers that are cut to standard widths and laid flat between joists in your attic. It’s most often made from fiberglass, but its base material can also be mineral wool, plastic fibers, or even cotton or sheep’s wool.¹
Blown-in – If it looks loose and lumpy, you’ve got blown-in, or loose-fill, insulation. It’s often made from cellulose (gray and dull), fiberglass (white with a slight shine), or rock or mineral wool (colors range from white to brown or gray).²
Spray foam – You can find hand-held spray foam in cans at your local hardware store to fill in small leaks and holes, but spray foam insulation is also installed commercially with pressure sprayers. It has a rigid surface and is often yellow-beige in color.
Combo platter – Because the insulation is often augmented over time, you may have multiple types in your attic. One common mix is blown-in on top of batt and roll. So, you may need a little gentle excavation to determine your insulation’s true identity.

If your inspection results in a “none of the above” answer and you live in an older home, you could have a dated type of insulation that contains chemicals or asbestos. As such, this type of insulation, which includes vermiculite and balsamic wood, should be removed immediately.³

2. Inspecting the Attic

Once you’ve determined what kind of existing insulation you have, the next step is evaluating its condition and the presence of any hazardous materials. This includes looking for:

Water damage or mold
Rodent or other pest infestation
Punctures, tears, and signs of aging or shrinkage in the insulation
Foreign objects like wood chips or nails mixed in with the insulation
Asbestos or hazardous chemicals from outdated insulation materials

While a quick visit to your attic can help uncover some of these issues, a professional attic inspection is critical to ensure potential hazards are correctly identified.

3. Creating a Removal Plan

The removal process is either done by hand or machine, which determines the attic insulation installation cost and time it’ll take to complete the process.

Removal by machine requires a high-powered vacuum with a large-diameter hose that can make its way up into the attic. This is the most efficient method, and can be used when you have:

Blown-in insulation with no foreign objects in it
Accessibility within and to the attic for worker movement and vacuum hose insertion
No hazards present (such as mold, animal waste, asbestos, or chemicals)

Workers will need to remove and bag old insulation by hand if you have:

Batt and roll insulation
Foam insulation
Blown-in insulation with construction detritus or other materials mixed in
Health hazards that can be further stirred up in the air by vacuuming
Attic areas with too little space or too many obstructions for vacuuming

Hand removal generally costs more because it requires more time and labor.

How Long Does Attic Insulation Removal Take?

For a 1,500-square-foot attic, professional removal of blown-in insulation without hazardous complications can take as little as 4 to 6 hours to complete. However, the time it takes to remove attic insulation is generally dependent on a variety of factors, including:

Attic size and access
The degree of obstructions, such as ducts, pipes, pillars, or debris
Type of insulation
The volume of insulation needed to be removed
Removal method (by hand takes longer than vacuum)
Presence of hazards

Health and Safety Considerations

Even in the best of cases, removing old insulation involves dealing with airborne fibers that are harmful to skin, eyes, and lungs. As such, workers must abide by standard safety precautions when removing insulation, which consist of:

Wearing protective gear like coveralls, heavy gloves, goggles, and respirators
Sealing off the rest of the house during the insulation removal
Draping and adding a protective covering to surfaces where a vacuum hose runs
Taking frequent breaks in warmer months to avoid heat exhaustion while suited up
Washing arms, hands, and face in cool water to discourage fiberglass absorption

Additionally, if asbestos is found in the attic, an asbestos abatement provider will have their own stringent health and safety practices to avoid any health concerns.

Attic Insulation vs Wall Insulation: What’s the Difference?

Written by Kevin on October 10, 2021. Posted in Attic Insulation. No Comments on Attic Insulation vs Wall Insulation: What’s the Difference?

When most people make a plan to insulate their homes, the attic is the first place they think to install that fluffy pink material.

But did you know that improperly insulated walls can also cost you time, energy, and money in the long run? That’s because walls, like attics, are major components in regulating heat flow in your home.

For the most cost-efficient, comfortable living environment, it’s best to insulate both your attic and your walls. That said, there are important differences between attic insulation and wall insulation that you should know about.

In this short guide, we’ll cover the important differences are location, type, and R-value requirements.

Location, Location, Location

It may seem obvious that attic insulation is installed in the attic, while wall insulation is installed in the walls. However, given the unique features of both spaces, it’s worth going over their layouts in more detail before you start replacing your existing insulation.

Attic Insulation

In many modern homes, the attic is the large rectangular or square space beneath the roof and above the main living space. The following are the main components of the typical attic:¹

Rafters
Perpendicular joints
Sheathing made of plywood

To properly insulate your attic, install new insulation between the attic’s perpendicular joists. You may also want to do an attic insulation installation between wall joists and around windows.

Walls

Although there are several types of walls, wooden walls are the most common in the modern home. A wooden wall’s layout dictates where insulation should go.

Most wooden walls contain the following:²

Top and bottom plates
Studs (wall, cripple, and trimmer)
Fire blocks

To properly insulate your walls, install home insulation in the spaces between wall studs. You may also need to hand-cut smaller pieces of insulation so that you can insulate small cavities around windows and doors.

Material Type

Given the distinct layouts of attics and walls, you’ll likely need different types of insulation to properly insulate these two spaces. This is because walls are largely uniform in terms of the spacing between studs while attics may feature irregular spacing or obstacles between joists.

Below, we’ve broken down the most common home insulation types for attics and walls.

Attics

As stated above, an attic space is often irregularly spaced. Due to this layout, the following insulation types are most commonly used in attics:

Loose-fill – Perfect for small spaces and irregular cavities, loose-fill insulation is constructed from various recycled materials, including fiberglass and plastic. The most common way to install loose-fill insulation is with a hose and blower. The loose-fill installation is simply blown into spaces in need of adequate insulation. However, if you’d like to save money, you can install loose-fill insulation by hand instead of hiring a professional for blown installation.
Blanket – When most people think of easily installable insulation for an attic space, they picture blanket insulation. This type of insulation comes in two forms: batts and rolls. Batt insulation is insulation cut into panels, while roll insulation comes in pre-cut rolls. If the space between joists is relatively uniform, blanket insulation can be ideal. However, if the space is irregular or filled with obstacles, blanket insulation may not cover every square inch.

Walls

While blanket and loose-fill insulation can be good for walls, the best insulation for walls is foam board or rigid foam insulation.³

This is because foam board insulation is moisture resistant, making it perfect for basement walls and/or walls exposed to the elements.

Foam board insulation has the following properties:

Constructed from various synthetic resins, such as polystyrene
Easy to apply with a special adhesive made specifically for foam boards
High R-values compared to the material’s thickness

R-Value Requirements

An insulation material’s R-value is a measurement of its ability to regulate heat flow. The higher its R-value, the more efficient the insulation material is at reducing heat flow.

Due to their different properties, attics and walls have different R-value requirements. These requirements largely stem from the home’s location, but, in general, wall R-value ranges are lower than attic R-values.

Let’s take a look at a few R-value ranges for attics based on location:⁴

Zone 3 – Comprising most of the South, Zone 3 homes have attic R-values between R30-R60.
Zone 5 – Homes in Zone 5 are largely located in the West and Mid-Atlantic. They require attic R-values ranging between R38-R60.
Zone 7 – Constituting the northernmost parts of the contiguous U.S., homes in Zone 7 have attic R-values between R49-R60.

While these three zones have three different sets of insulation R-value requirements for attic spaces, homes in any geographic area can benefit from wall insulation with R-values between R13-R15 for 2X4 walls and R19-21 for 2X6 walls.

Attic Construction: For All Your Insulation Needs

How Much Does It Cost to Remove Attic Insulation?

Written by Kevin on September 20, 2021. Posted in Attic Insulation, Insulation removal. No Comments on How Much Does It Cost to Remove Attic Insulation?

The cost to remove old insulation from attic spaces will vary based on the type of insulation, where you live, and whether it’s a single service or part of a replacement project. To that end, a very basic price range for insulation removal is $1 to $2 per square foot.

When determining whether or not insulation removal is worth the cost, determine the type of insulation currently in your home, if it needs to be completely replaced or simply added to, and if it contains any hazards or toxins that may spread during removal.

If your attic insulation isn’t doing its job, getting it in tip-top shape is a critical investment that can reduce your heating and cooling costs while improving your home’s comfort. While you may want to remove your attic insulation yourself, it is highly advised to leave this job to the professionals. Let’s figure out whether you need it removed, and what goes into estimating the cost.

How Long Does Attic Insulation Last?

There are many factors involved in pricing an attic insulation removal project, but the first question is: do you actually need your insulation material removed?

When attic insulation hits the top of your to-do list, it’s often because you’re feeling the signs that your home is under-insulated, whether that’s higher than normal electrical bills or a persisting draft. Usually, the fix is adding more home insulation on top of what’s already there, rather than removing it.

When basic home maintenance is taken care of, modern types of attic insulation don’t require frequent replacement. However, insulation in older homes may need a makeover, especially if it is damaged insulation or filled with harmful chemicals. To that end, let’s take a look at the life expectancies of certain types of insulation:

Spray foam – Spray foam insulation lasts up to 80 years. It’s air-tight, mold-resistant, and does not absorb moisture. If it requires removal, it’s generally due to pests or damage from construction activities.¹
Fiberglass – Can last 80 to 100 years, but may begin to fail after 15 to 20 years. It can be damaged by moisture as well as gravity over time. Its effectiveness is dependent on it staying light and fluffy. Unless it is water or pest-damaged, it’s generally safe to leave in place while adding insulation on top, as needed.
Mineral wool – Lasts 30 to 80 years, depending on its variety and base material. It’s also prone to moisture and mold growth. New insulation can be applied over it if it’s dry and undamaged.
Cellulose – Lasts 20 to 30 years, but will begin to degrade after about 15 years. Cellulose insulation is vulnerable to moisture and mold. If dry and undamaged, insulation can be applied on top of existing attic insulation as needed.

When Does Attic Insulation Need to Be Removed?

Separate from whether your insulation is nearing the end of its life expectancy, some types of insulation need to be carefully and thoroughly removed based on damage. Plus, some older types of insulation can be potential hazards to your and your family’s health due to the presence of asbestos and other chemicals.

In general, there are four reasons why you may need to remove and replace your attic’s existing insulation.

#1 Removal Due to Hazardous Types of Insulation

While owners of newer homes needn’t be concerned, attic insulation in an older house may need removal since many homes were insulated with types of insulation that pose safety hazards. These include:

Vermiculite – If your home contains vermiculite insulation, the safest option is to have it removed by asbestos abatement professionals. Although the EPA recommends testing and only requires certified asbestos abatement if the results are 1% or higher asbestos. Even at lower amounts, regular insulation removal methods will produce airborne asbestos in your home so you’ll need to take the proper safety protocols, such as isolating the area.²
Balsamic wool – Made from cedar tree shavings, balsamic wool insulation was popular in mid-20th century home construction but is now known to contain carcinogens.
Cellulose – Made from recycled newspaper, older cellulose insulation may pose a fire hazard.

Since drafty homes are often corrected by adding insulation on top of existing insulation, your home may contain hazardous insulation under the newer coverings. A professional inspection can help you find whether or not you have potentially hazardous insulation in your home.

#2 Removal Due to Water or Mold

Insulation materials are designed to resist humidity and moisture, but an unattended water leak can lead to mold. The presence of mold in your insulation is a danger to your family’s health and is another circumstance that warrants professional removal. Spores of mold within your old attic insulation may cause:

Headaches
Coughing
Digestive problems

#3 Removal Due to Pest-Infested Insulation

Animal urine and droppings create a toxic environment that will impact your home air quality over time as well as break down both insulation and structural materials. Rodents and insects can also tunnel through and eat into attics and insulation as they nest and proliferate.

If there is significant evidence of pest infestation, you may need complete insulation removal to return your attic to a clean and safe state.

#4 Removal Due to Other Damage

Though durable, insulation becomes vulnerable when it is punctured or begins to break down to open up space between points of insulation.

For instance, if your roof was poorly installed, it can send wood chips into the insulation. These holes allow both moisture and dirt into the insulation, which compromises its ability to repel moisture and creates an environment where mold can grow.

How to Tell if Your Attic Insulation Needs Removal

There are signs to look for in your attic that will help you figure out whether your insulation needs removal and replacement.

Grab a flashlight and take a look in your attic space. You may need removal if you can identify:

Crumbling insulation – Your old attic insulation may be expired and need replacement if it crumbles when touched or has other signs of damage due to aging.
Moisture – If you can see visible water leakage or damage, or you can smell or feel the moisture in the air, you may need the removal of insulation and mold treatment.
Mold – Mold may or may not be visible to the eye. You may see it as black spots or streaks on the insulation. (For fiberglass insulation, black coloration might be dirt that is accumulating based on the presence of an air leak.)³
Unwanted guests – If you can see or smell evidence of animal waste, nests, or tunneling, you may need to remove current insulation and possibly repair any damage to the structure from pests. This may not be a surprise to you if you’ve already heard the pitter-patter or chewing of these pests when the house is quiet.

However, the best test is going to be a professional inspection and report. A professional can help identify any potential problems that you may not be able to easily see, smell, or hear yourself.

How Is Attic Insulation Removed?

Inspecting and preparing the attic space for insulation removal is a critical first step to this process. If there is significant infestation or contamination to clean up and protect the rest of the house from, your removal rate will reflect that.

Depending on the type of insulation or damage, removal can be done by machine or by hand. However, bagging insulation and removing it by hand is more time-intensive, and thus more expensive.

Some things to consider when deciding whether to use a machine or remove the insulation by hand include:

Contaminated insulation – If it contains materials such as wood chips, insulation must be bagged and removed by hand.
Batt insulation – Batting must be rolled up and taken out by hand.
Blown insulation – Machine removal involves vacuuming blown insulation with an industrial device that keeps the insulation contained until after it leaves the home.

How to Estimate Your Attic Insulation Removal Cost

So how much does it cost to remove attic insulation? As we noted at the beginning of this article, the average price range for attic insulation removal is $1 to $2 per square foot. Costs can range upward if the condition of the insulation is particularly poor. When pricing your specific project, factors that affect the quote include:

Amount of insulation – Your price per square foot may be impacted by just how much insulation is currently present. For instance, if previous homeowners have already added blown-in insulation over fiberglass batting, that will require more labor to remove.
Removal process – Does the current insulation require removal by hand or can it be vacuumed out? Generally, by-hand removal will cost you extra since it requires more labor and usually takes more time.
Vacuum truck access – If machine removal is used, the process will involve running a six-inch-diameter hose through your attic. The hose is connected to a vacuum device in a truck outside your home. If this is not possible due to space issues, then your attic may require removal by hand rather than a machine.
Attic access – How easy or difficult will it be for workers to enter and move through your attic space? Will they encounter pillars, pipes, debris, or other obstructions? This can affect both the methods used and the amount of labor involved in your job.
Presence of hazards – If hazards such as mold, asbestos, or animal waste are present, removal may need to be done by hand and may require additional steps and safety considerations, such as quarantining the house for a designated period of time.

How Attic Construction Professionals Can Save You Money

Removing insulation that contains mold, animal feces, or asbestos requires careful handling to protect the workers and prevent contaminants from spreading through your home during removal.

Removing Blown In Insulation from Your Attic: Everything You Need to Know

Written by Kevin on September 18, 2021. Posted in Attic Insulation, Insulation removal.

Blown-in insulation fills every nook and cranny of your attic—which seems like a great idea right up until you decide to take it out!

Removing blown-in or loose-fill, insulation is a hot, uncomfortable, and dirty project. The process, time, and blow insulation removal cost depend on factors including the size and accessibility of the space as well as the removal method you use.

Whether you’re working with professionals or tackling it yourself, it’s helpful to understand both the steps involved and the tools needed to do the job. In this short guide, we’ll cover everything you need to know.

#1: Inspect Your Attic Insulation

An important part of learning how to remove blown in insulation from your attic is understanding the possible dangers involved. Attics are dusty at the best of times, but if yours has water damage or signs of pests making themselves at home, it poses health and safety hazards. Look for:

Signs of infestation – Blown-in insulation can be a cozy material for mice, squirrels, and other unwanted guests. If you can see or smell signs of nesting, urine, or droppings, then the process of attic insulation removal will release additional toxins into the air during removal of old blown insulation.
Mold or water damage – If you see black streaks or spots, or any sign or smell of water damage in the attic, the insulation removal could stir up mold spores.

If you are removing spray foam insulation, you must proceed with caution. Old blow insulation can actually cause damage to your health if dealt with incorrectly. Both of these issues are dangerous to workers and can result in airborne toxins spreading to the rest of your home. If present, they may impact the removal method you choose.

#2: Evaluate Your Working Environment

The access to and within your attic can affect the time you or a professional will need to invest in the job. A large unfinished attic with few obstructions that allows workers to move freely is going to be a different job than a small crawl space riddled with ducts and pipes.

Assess the work environment of your attic, including:

Vacuum access – The machinery will be located outside, often in a truck or trailer. Is there space where a vehicle or machine can be situated so that the hose has a window or other point of entry to the attic?
Obstructions – Does your attic look like an octopus convention? Is it riddled with ducts, pipes, cabling, or wiring? And are those items in good repair or fraught with loose connections?
Freedom of movement – Will removal workers be able to stand and move easily throughout the attic? Are there nooks and crannies that will be difficult to access?

#3: Determine Removal Method

The preferred method of removing blown in insulation is by machine, using a vacuum process to suck the insulation out of the attic. This is the most efficient option and can save both time and money.

If you’re doing the removal yourself, you’ll need to rent a high-powered insulation vacuum. These are usually gas-powered and they’ll typically come with around 150 feet of hose to reach from the attic to the vacuum outside. Larger ones may come in their own trailers to haul to and from your home.

In some circumstances, however, you’ll need to bag the insulation by hand rather than using a vacuum process. This will be the case if your existing insulation contains:

Airborne toxins – If mold or animal waste is present, they can be stirred up and released more into the home through the vacuuming process.
Water – If the insulation material is saturated with water, the vacuum will not be able to pull it cleanly through the hose.
Foreign objects – If the insulation has been penetrated by objects such as wood chips or nails during roofing or other home construction projects, those objects could interfere with or damage the vacuum.

#4: Understand Health and Safety Considerations

Remember that even in the best circumstances, old insulation removal involves stirring up fibers that you don’t want to swallow or have on your skin.

The most common types of blown-in insulation are fiberglass, rock wool, and cellulose insulation material. Although fiberglass is popular, it’s also a carcinogen that can damage your eyes, skin, respiratory system, and lungs.

Protection during the removal process includes:

Skin coverage – If you’re tackling insulation removal during the warmer months, it’s going to be an uncomfortably hot job, but you need to keep your arms and legs as well as your hands fully covered.
Breathing protection – Use a respirator rather than a simple fabric or plastic face mask to prevent lung damage.
Washing up – Use cool water to wash your hands, arms, and face. Warm water can open your pores and allow your skin to pull tiny particles deeper.¹

Quick tip: When fiberglass touches you, it can cause a stinging sensation. Scratching or rubbing it will push it into your skin. Wash the area instead, following the protocol above.

#5: Rent and Buy the Tools You Need

To safely remove your blown-in attic insulation, you either need to fill up a shopping cart or find a single item: a trusted professional attic removal team.

If you’re removing your old attic insulation yourself, you need to gather:²

A rented high-powered insulation vacuum
Extra rented hose and connectors if needed for your attic access
Insulation bags that fit the vacuum
Gas to power the vacuum
Coveralls
Respirator
Protective goggles
Heavy-duty work gloves
Headlamp
Duct tape
A good friend

Although running the vacuum in the attic is generally a one-person job, a friend to help throughout the process is a must-have. That person can keep an eye on the vacuum for any clogs in the hose or connection issues, make sure the insulation bags aren’t overfilled, and replace them as needed when removing old attic insulation.

#6: Get It Done!

You’ve gathered up everything you need and had a good breakfast. If you’re ready to jump into your first workday, follow these steps:

Preparation – Move the vacuum close to the door or window you’ve selected for access and clear the path. If you’re running it through the house, lay down protective material. Close all other doors and windows in the house.
Suit up – Make sure you’ve got all your protective gear, and suit up as soon as you’re ready to work in the attic space.
Vacuum – Make sure you’ve got someone to check on the machine down below as you turn it on and begin vacuuming. Take a logical path through the attic space that helps you set small goals and appreciate as you complete each area.
Pause for glitches – You may need to pause to navigate around obstacles, replace insulation bags, or address clogs or leaks in the vacuum hose and connectors.

While you’re in the removal stage of your existing insulation, there are some ways to make the process go as efficiently as possible:

Stay alert – As you make your way through the attic, take a moment to carefully inspect each area in all directions: left, right, up, and down. Look for nails sticking through the roof or floor joists, and for any weakness in surfaces that you walk or put weight on if your attic doesn’t have a finished floor.
Keep inspecting – The middle of the job isn’t a great time to realize there is mold or infestation present, but the fact is, you may only see signs of these hazards as you move further into the attic and remove some insulation. If that occurs, observe what you can and take a break to reevaluate whether you need to call in professionals who can work safely in and fully clean up a toxic environment.

At the end of the day, there are no magic tricks to removing blown in insulation from attic easily or in a snap—aside from hiring a professional.

Once you’re done, you’ll be a critical step closer to making your house a home that uses less energy and provides more protection and comfort!

#7: Clean Up and Dispose of Removed Insulation

It’s not the fun part, but at least you can see the light at the end of the tunnel! Clean up for insulation removal includes:

Vacuum removal – Move the hose back outside and prepare the machine to be returned.
Cleaning attic surfaces – To avoid stirring up remaining fibers, use a damp clean method like a wet shop vac to do a final clean-up of your attic. Ensure proper ventilation so surfaces can dry cleanly.
Undressing the house – Remove any protective sheeting or drapes used inside the house carefully and give family members the all-clear!
Disposal of insulation bags – Contact your city or county waste management organization to find out how to dispose of the old insulation. You may end up with a half dozen or more full garbage bags if you have a particularly large attic. Transport them via a trailer if you need to bring them to a disposal site to prevent any transfer of unhealthy particles from the bags to your vehicle interior.

Ready to Partner with Professionals on Attic Insulation Removal?

Your smartest first step in an attic insulation project is to obtain a professional opinion. While dedicated DIY’ers can take on projects like this, the potential for hidden health hazards makes it vital to get a second set of eyes on your attic before work begins.

Should I Remove My Old Attic Insulation: A Helpful Guide

Written by Kevin on September 14, 2021. Posted in Attic Insulation, Insulation removal. No Comments on Should I Remove My Old Attic Insulation: A Helpful Guide

If you own a house with an attic, chances are that you don’t visit the space very often. Maybe you use it as storage—a place to stash your boxes of keepsakes, dusty old furniture, or holiday decorations that just don’t fit anywhere else.

But even if you only go up into your attic every once in a while, it’s hard to miss its most important feature: the insulation. And if you suddenly notice an off-odor or extreme temperature in your attic, you might suddenly start to wonder, “Should I remove my old attic insulation?”

Whether you want to avoid attic insulation removal costs or you’re interested in doing a home improvement project, this article is here to help. We’ve put together this complete guide to walk you through the reasons why it’s important to remove old attic insulation and how you can do so safely in order to replace your attic insulation.

Remove Old Attic Insulation for Better Heating and Cooling

The primary reason for removing old attic insulation is to ensure that your home is heated and cooled properly. With age, attic insulation typically deteriorates, meaning that it loses its ability to effectively regulate temperatures and insulate your home. Ordinary deterioration can be caused by shifting or settling insulation materials, or even environmental factors like excessive moisture or damage from direct sunlight.¹

Regardless of the cause, the unfortunate reality is that attic insulation does not last forever. Instead, it eventually needs to be removed and replaced for adequate home temperature control.

Removing old attic insulation has these added benefits: ²

Other Reasons to Remove Old Attic Insulation

Aside from natural wear and tear or environmental degradation, there are several other reasons why removing old attic insulation is a good idea. In these cases, attic insulation removal is not only important for effective installment but also a necessary step for the health and safety of your family.

Asbestos

While not all insulation material contains asbestos, it is more commonly found within older homes. Asbestos fiber was popular in construction before the 1980s because this natural mineral is resistant to heat, electricity, and corrosion. These qualities that make it an effective insulator, however, also make it quite dangerous and toxic to the human body.³

Both non-cancerous and cancerous diseases and other health problems can result from exposure to high quantities of asbestos over time.⁴

Although the health risks of asbestos are well known now, they weren’t always, so the mineral can be found in older buildings and homes. The most common kind of asbestos insulation that might be found in an attic is vermiculite insulation, though not all types of this insulation contain asbestos. Nevertheless, it is always better to err on the side of caution and at least look into testing your older insulation for asbestos to be sure of its contents.

Mold

Unfortunately, mold is commonly found in indoor environments like homes. Moldy attic insulation can result from a variety of factors that are more likely to occur (or become more severe) over time, including:

Humid climates
Improper venting
Leaks from heating and cooling systems
Extreme storms

If mold has made its way into your attic insulation, removal is crucial. The moisture that eventually leads to the development of mold can cause the rapid deterioration of insulation, rendering it much less effective.

More importantly, mold exposure can pose many health risks in humans, ranging from mild to severe allergic reactions and long-term upper respiratory issues.⁵ If you have contaminated insulation in a crawl space or attic, it is essential to get it removed by an insulation professional right away.

Pest and Animal Infestation

Critters are another common menace that may warrant attic insulation removal. Infestations are particularly common in older homes, where it is more likely that there are weak spots in the roof or attic exterior.

Possible unwanted intruders include:

Raccoons and squirrels – These are the most likely among the larger animal inhabitants of attics. Raccoons and squirrels like to use attic spaces as dens and nests, particularly in the warmer months (“birthing season”) as mothers seek to protect their newborns.⁶
Mice and rats – It’s not uncommon for these other rodents to make attics their temporary or permanent home, especially in the colder months as they seek refuge from the inhospitable temperatures outside.
Bats – For these creatures, attics function just like caves, with plenty of dark spaces and places to hang.⁷
Insects – Wasps, hornets, and termites are also known for choosing attics as nesting spaces.

Aside from seeing the actual culprits themselves, signs of pest and animal infestation include:

Droppings or urine
Scurrying or squeaking noises
Nests made from organic materials
Disturbed or damaged insulation

Although certainly a nuisance, pest and animal infestations are also a serious problem that can result in extensive damage to your attic and your existing insulation. After such an infestation, old attic insulation will likely need to be replaced.

Even if no damage is readily visible, it’s important to replace any insulation that could contain droppings, as pests and animals can be vectors for disease.

What is an Attic Insulation Calculator?

Written by Kevin on September 10, 2021. Posted in Attic Insulation. No Comments on What is an Attic Insulation Calculator?

Your attic is an essential space—it’s the place to store everything from holiday decorations to camping equipment and the first line of defense against a high energy bill.

That said, your attic can wreak havoc on your wallet if it’s not properly insulated. This is because your attic’s insulation helps regulate your home’s heat flow. In short, an under-insulated attic can greatly drive up energy costs.

But how do you know how much insulation you need to properly insulate your attic?

The answer: an attic insulation calculator.

Knowing what an attic insulation calculator is and how it works will greatly benefit you when it comes to insulating your attic.

Calculating Insulation Requirements

Although it sounds like an intricate machine, an attic insulation calculator is simply a mathematical formula that lets you know roughly how much insulation you’ll to properly insulate your home.

In its most basic sense, insulation consists of any material placed in a home’s gaps or crevices in order to regulate heat flow. Without proper insulation, heat escapes from your home in the cold winter months and enters your home during summer.

To calculate insulation requirements, follow the steps below.

#1 Measure Your Attic

If your attic is square or rectangular, measuring your attic should be a piece of cake. Simply measure your attic’s length and width and multiply those two figures together to yield your attic’s square footage.

If your attic consists of triangular spaces, you’ll need to measure the height and width of each triangle. Then, divide the base in half and multiply it by the triangle’s height to yield the area’s square footage.

#2 Measure Current Insulation Levels

If your attic’s uninsulated, you have no old insulation to measure. But if you have existing insulation, take your insulation’s measurement by measuring from the attic floor to the top of your insulation. With this information in hand, you’ll know how much more insulation you might need to improve your energy efficiency.

If you’re unsure of how much more insulation you’ll need, consult the Department of Energy’s insulation chart.

#3 Calculate

To calculate how much insulation material to purchase, simply divide your attic’s square footage by the square footage of insulation in the manufacturer’s package (assuming you’re purchasing pre-cut batts or rolls). This will give you a rough estimate of how much insulation you’ll need and how much you can expect to pay for proper insulation.

You now have an easy and efficient attic insulation cost calculator.

Beyond Square Footage: Calculating Insulation Needs By Material

While the above calculator can give you a rough estimate of how much material you’ll need, the specific amount will vary based on the material you choose to insulate your attic or crawl space.

Though there are several different types of attic insulation, the most common include:¹

Blanket – Made from fiberglass, natural and synthetic fibers, and mineral wool, blanket insulation comes in two forms: rolls or pre-cut panels known as batts. Inexpensive and easy to apply, blanket insulation material is perfect for spaces between joints, studs, and beams.
Loose-fill – Constructed from cellulose fiberglass and mineral wool, loose-fill insulation is ideal for areas that are already finished or areas with obstacles or unusual designs. Although you can install loose-fill insulation by hand, it’s most commonly installed by blowing the insulation from a blower attached to a hose. Loose-fill insulation is perfect for attics.
Spray foam – Similar to loose-fill insulation in that it’s perfect for attics, spray foam insulation is typically installed via small spray containers. Spray foam insulation is manufactured from various materials, including phenolic and polyurethane.
Reflective – As its name implies, reflective insulation works by reflecting heat away from a home. It’s made from various materials including foil kraft paper, cardboard, and plastic film, and regulates downward heat flow exceptionally well.

These different materials also have different insulation R value types. A measurement of an insulation’s effectiveness at regulating heat flow, R-value is a useful tool when deciding between different types of insulation and the amount of insulation you’ll need.

It’s best to consult an insulation chart to determine precise R-values and costs, but in general, materials that have lower R-values, such as blanket insulation, cost less per square foot per R-value than materials with higher R-values, such as spray foam.

Calculating R-Value

To calculate R-value, divide a material’s thickness in meters by its thermal conductivity. R-values are measured in ft. °F. h/BTU. In general, the higher a material’s R-value, the better it is at reducing heat flow.

While your R-value differs based on a number of factors, chief among these is your home’s location. For instance, while attics in the Upper Midwest and New England require insulation with R-values ranging between R49-R60, attics in the Deep South require insulation with R-values ranging between R30-R60.

Attic Construction: For When You Need The Right Measurement

Although doable, calculating your attic’s insulation takes time, energy, and money. Besides, why take the chance that your calculation is slightly off?

Fortunately, Attic Construction is here to help. By making sure your attic’s insulation requirements are met, Attic Construction’s the only attic insulation calculator you’ll need.

Is Asbestos in Your Attic Dangerous?

Written by Kevin on August 23, 2021. Posted in Attic Insulation. No Comments on Is Asbestos in Your Attic Dangerous?

As a homeowner, you have numerous tasks on your to-do list, from finishing your basement to finally replacing that burnt-out porch lightbulb.

If you only use your attic to store holiday ornaments, its problems may be the last thing on your mind. But if your neighbor or contractor mentions that your insulation looks like it may contain asbestos, you might be left wondering, is asbestos in the attic dangerous?

The short answer is yes. Long-term exposure to asbestos can cause serious health problems.¹

In this guide, we’ll explain the ins-and-outs of asbestos, its potential health hazards, and the best way to remove the harmful substance from your home. If you don’t know what asbestos in an attic looks like, our team is here to help.

What is Asbestos?

Before the 1980s, asbestos fiber was commonly used as a building material. Builders previously used asbestos because it resists electricity, corrosion, and heat—making it an ideal insulator.²

This naturally occurring mineral is toxic—and unfortunately, its tiny particles make it easy to inhale. Over time, constant exposure of harmful asbestos fibres can lead to lung disease or a number of other health problems.

While the risks of asbestos are now well-understood, if your home was built before the 1980s, your insulation could still be a cause for concern.

If asbestos is in an attic, it’s usually in vermiculite insulation.³

Not sure what material was used in your attic? Take a look to see if it has the following characteristics:

A pebble- or stone-like texture
A light-brown, greyish-silver, or gold hue
Shiny flecks throughout

If you find what appears to be vermiculite insulation in your attic, don’t immediately panic.

Not all vermiculite insulation contains asbestos. A house built after the 1990s is less likely to have an asbestos problem. However, it’s always best to be cautious and take the necessary safety precautions when testing your insulation material.

Health Impacts of Asbestos

Vermiculite insulation that contains asbestos is most dangerous if disturbed. For example, dedicated DIY-ers may try to replace their insulation material on their own. But removing the old insulation means sending asbestos fibers into the air.

Without property safety precautions, these asbestos fibers can be inhaled into the lungs and cause serious health problems.

The four most common health impacts from asbestos exposure include:⁴

Asbestosis – A non-cancerous condition that includes difficulty breathing because of scarring in the lungs.
Pleural Disease – A non-cancerous condition that includes the thickening of the membrane around the chest cavity and lungs as well as a build-up of fluid around the lungs.
Mesothelioma – A rare type of cancer that can impact the lining of the chest cavity, the lungs, the abdominal cavity, or other internal organs.
Lung Cancer – A type of cancer in which a malignant tumor obstructs airways.

With most of these conditions, it can take a minimum of 15 years to develop symptoms and receive a diagnosis.

So it’s best to have your house checked for asbestos particles even if you’re not experiencing exposure symptoms. The cost of professional asbestos removal is certainly worth it when considering the risk it can have on your health.

Who Is At Risk?

Asbestos is toxic and can be extremely dangerous. However, not all people exposed to asbestos develop health problems. A person’s risk for developing a health problem from exposure depends on multiple factors, including:⁵

How long and often a person is exposed
The amount of asbestos in the air
Whether the person has a history of respiratory conditions
Whether the person smokes
How long it has been since the exposure

Often, asbestos-related health conditions arise from years of exposure in the workplace.

However, home-related exposure is still possible and can still lead to health problems.

What To Do If You Suspect Asbestos

Even if you’re not sure if your attic insulation contains asbestos, it’s important to take precautions.

If you’re concerned there might be asbestos in your attic, the first rule is to leave it alone. Any disturbance could lead to scattering asbestos fibers into the air around you.
Until you have your insulation inspected by an accredited asbestos expert, restrict access to the attic. Don’t store anything in the attic or move your pre-existing storage boxes.

Avoiding all contact with the insulation is the most important step you can take to keep your household safe. Do not remove the insulation yourself, and be aware of disturbing it through other house renovations. Performing any renovations near the asbestos such as drilling, hammering, sanding, and more could disturb it and send fibers into the air.

Instead, call a professional to help you safely remove and replace asbestos insulation.

Cost to Remove Asbestos Insulation in Your Attic

Written by Kevin on August 19, 2021. Posted in Attic Insulation. No Comments on Cost to Remove Asbestos Insulation in Your Attic

When you find out that you have asbestos insulation in your attic, your first thought is that it must be removed immediately. Your second thought is how much is asbestos abatement going to cost?

We know the idea of asbestos lurking above you is disturbing—after all, you’ve heard countless stories about the dangers of asbestos exposure such as lung cancer and other illnesses. And, while asbestos is indeed hazardous, we’re here to reassure you that the insulation in your attic can be dealt with without risking your physical or financial health.

In this blog, we’ll explain the cost of asbestos removal and the proper steps to take if you suspect asbestos material is lurking in your attic.

The Cost to Remove Asbestos Insulation in Attics

We’ll come out with the bad news right away—we can’t give you a precise quote for removing asbestos from your attic ceiling.

As we’ll explain, asbestos removal is a multi-step process involving, at minimum, an asbestos inspector and a certified asbestos removal professional that can take care of the old insulation.

Therefore, the asbestos removal cost will depend on several factors including:

Where you live – Because of the potential health hazards, asbestos remediation is never a DIY job. And just like car insurance and real estate, the cost of asbestos removal services varies between geographic regions.
The contractors you hire to inspect and remove – Your local market features contractors with varying degrees of experience and various demands on their schedules. No matter what, it’s important to hire an asbestos contractor from a reputable asbestos disposal company who has completed the Environmental Protection Agency’s asbestos training to have your asbestos removed.1 Beyond that, look for professionals with good reviews and affordable rates.
The size of your attic – Do you live in a two-bedroom home with a relatively small attic? You’ll likely be looking at a lower overall asbestos removal cost than would the neighbor with the 1,000 sq foot attic above their mini-estate.
The amount of insulation you need to remove – You might think that your attic’s square footage is the only factor involved in the volume of asbestos contamination and the cost of removing asbestos. However, the total amount of insulation depends on the thoroughness of the original contractor’s job, whether they used a mix of materials, and the specific shape of your attic.
The type of new insulation you elect to install – Once you’ve removed the material containing the hazardous material of asbestos waste, you’ll likely want to replace the insulation right away. Otherwise, you’ll risk higher utility costs. Likewise, a lack of insulation protection could expose your home to further damage from humidity, extreme heat, and extreme cold.

Ready to start getting quotes?

Not so fast. In some cases, attic insulation removal is not the best option—and even if it is, it’s important to thoroughly understand asbestos material and the risks of asbestos exposure.

Next, we’ll lead you through a step-by-step guide to finding the best for your specific asbestos abatement situation and budget.

Step 1: Understand Your Insulation

You already know asbestos is dangerous. But do you understand what makes this building material risky?

In short, asbestos is a toxic mineral with fine particles that can easily be inhaled, leading to lung damage and serious health issues. Agitating or removing your insulation can release these particles.

If you’re concerned about asbestos contamination, you won’t want to poke, prod, or remove your old roof insulation yourself or undertake disposal. Instead, take steps to make sure it actually contains this mineral and consider asbestos testing.

There are two types of insulation used in residential properties that may be an asbestos containing material: batt insulation and vermiculite.

Batt Insulation

The good news is it’s very rare to find batt insulation containing asbestos still in use.² The loose-fill style of insulation containing asbestos was far more ubiquitous.

However, if your attic has very old batt insulation, you should get a laboratory test to confirm that it’s asbestos-free.

Vermiculite Insulation

The biggest concern for asbestos in attics is vermiculite insulation.³ Vermiculite insulation is made of small pebble-sized pieces. It’s generally silver-gold or brownish-grey and looks like a mini-accordion.

Like asbestos, vermiculite is a mineral. On its own, vermiculite isn’t harmful. Unfortunately, most of the vermiculite used to insulate attics in the United States from the 1940s through the 1970s came from the same mine in Libby, Montana.⁴ This mine was contaminated with asbestos, tainting all of the vermiculite that came from it.

Step 2: Avoid Disturbing Your Vermiculite Insulation

If you spy vermiculite insulation, your first step is alerting all family members to avoid entering the attic, removing stored boxes, or agitating the insulation.

Why?

Asbestos is at its most hazardous when it’s friable, or easily crumbled. This allows the tiny fibers to break free into the surrounding air where they’re inhaled. The small pieces of vermiculite used in attic insulation can release many asbestos fibers when disturbed.

If the option to leave vermiculite insulation alone exists, the EPA recommends that you do just that.⁵ Think of it like a bumblebee. If you don’t bother the bee, it won’t harm you. However, if you frighten it, you might get stung. If undisturbed, the vermiculite won’t become friable. If you move it around, it can crumble further and release microscopic fibers into the air of your home.

Unless you plan to finish your attic and use it as a living space, odds are you don’t spend much time up there. If this is your family’s situation, the EPA recommends that you avoid:⁶

Storing boxes near any place in your attic that will require you to disturb the insulation to move the boxes.
Letting children play in the attic if vermiculite is exposed.

The bonus? You’ll save money by avoiding the cost of asbestos removal.

Step 3: Before Removal, Hire an Inspector

While it’s recommended that you leave vermiculite insulation alone if at all possible, we know there are situations where it must be removed. These include:

Rodent or other pest infestations
Water or fire damage to the attic
Renovation requiring removal of existing structural elements

When you’re ready to hire an asbestos removal company, the first step is finding a qualified asbestos inspector to assess the insulation.¹ They’ll take samples and discuss the removal of the vermiculite with you. You’ll also receive a written summary of their recommendation for removal.

The inspector will also follow up after the insulation has been eliminated to ensure that the job was done correctly.

Step 4: Hire a Contractor

Hiring a contractor to remove the asbestos can be one of the most difficult steps. You need a person who will follow guidelines precisely to avoid contaminating your home with asbestos fibers.

As we’ve noted, the EPA stresses the importance of only choosing contractors certified to remove asbestos. Each state maintains a list of currently licensed contractors.⁷ They also recommend that you get everything in writing from the contractor you select for the insulation removal.

Once again, costs can vary between contractors, so we recommend getting several quotes.

Step 5: Monitor the Home

After the contractor’s work is complete, either the inspector who provided your original evaluation or an independent air testing contractor will need to monitor the air quality of your home.

It’s important to have someone other than the contractor who performed the removal work do this step to avoid a conflict of interest.
For example, if you hire an inspector who works in the same office as the contractor you choose, they might act in their business’ best interest rather than yours. Working with two people who don’t have connections to one another ensures you aren’t caught in the middle.

Keep in mind that this extra visit will likely come at an additional cost. However, it’s more than worth it to ensure your home is safe and healthy.

Step 6: Install New Insulation

The final step in the vermiculite removal process is to install new insulation. We know—it might be tempting to go without insulation, especially if you live in a warmer climate. However, it’s critical for temperature regulation no matter where you are.

The right insulation keeps warm air from leaching into your air-conditioned space and cold air from seeping in from outside. Both of these mean lower energy bills and a more comfortable home.

Your exact insulation needs will depend on the climate where you live and the size of your attic. A professional can advise you on the best insulation for your home.

Call Attic Construction to Finish the Job

Asbestos in Your Attic: Everything You Need to Know

Written by Kevin on August 15, 2021. Posted in Attic Insulation. No Comments on Asbestos in Your Attic: Everything You Need to Know

We love the charm, character, and quirks of old houses. How many new homes have true hardwood floors, built-in cabinets, and stained glass windows?

Of course, squeaky floorboards, dusty attics, and strange room shapes are additional parts of owning an older home. But what do you do if your house contains hidden dangers behind the charming features?

Unfortunately, if you’re buying an older house, asbestos is sometimes part of the deal. This toxic mineral was once prevalent in attic insulation and other building materials, and may still be lurking in your home. Asbestos can be dangerous for you and your family, which is why it is so important to check for asbestos contamination as soon as possible.

But what does asbestos look like and how do you know if you have it? We’ve assembled this guide to help you understand the dangers of asbestos, identify it in your home, and take appropriate steps for safe, professional removal.

What Is Asbestos?

“Asbestos” refers to a group of six different minerals that are made of very thin fibers.¹ Each of these minerals is:

Stong
Fireproof
Heat resistant
Chemical resistant

These characteristics once made asbestos fiber an appealing additive to many construction products.

Like other minerals, asbestos fiber is mined from the earth. It’s found throughout the United States and in many other countries. While the peak of asbestos mining in the U.S. occurred during the 1960s and 70s, the use of asbestos dates to a much earlier time.

A Brief History of Asbestos

Asbestos was first incorporated into pots and cooking utensils over 4,500 years ago by Scandinavian cultures.² 2,000 years later, the Ancient Romans noticed that slaves working with asbestos became ill, although this knowledge didn’t stop its use. The Industrial Revolution spurred the commercial manufacture of asbestos products in the late 1800s. This ubiquity led to the discovery of a link between cancer and asbestos exposure in the 1930s.

Unfortunately, asbestos had become far too popular and valuable, so the industry ignored the warnings from scientists and medical professionals until Congress finally began federal regulations on asbestos in the 1970s.

In 1989, the Environmental Protection Agency (EPA) attempted to ban the use of asbestos in new products and recommended phasing it out in others. The ban was overturned two years later after heavy pressure from lobbyists for the asbestos industry.

Despite the known dangers, asbestos is still included in many products today.

The Dangers of Asbestos Exposure

Long-term exposure to asbestos fibers can cause serious health problems.

The lungs are most seriously impacted by inhaling needle-like asbestos fibers. The three lung diseases closely associated with asbestos are:³

Asbestosis – This chronic condition aggravates lung tissues and creates scarring. It can contribute to cardiac failure and is often fatal.
Mesothelioma – Mesothelioma is a cancer of the membrane that lines the lungs, abdomen, chest, and heart. Almost every case diagnosed in the U.S. is linked to asbestos exposure.
Lung Cancer – Other lung cancers are the leading cause of death among those who have been regularly exposed to asbestos. Smoking cigarettes combined with asbestos exposure makes one even more likely to develop lung cancer.

Signs You May Have Asbestos in Your Home

First things first: the only sure way to know if materials in your home contain asbestos is to get them tested in a laboratory.

However, there are some clues that your home might have asbestos. Do any of the following apply to your house?

Built before 1980
Features popcorn ceilings and textured paint
The exterior is built of cement shingles and siding
Attic insulation is loose fill (i.e., not made of a uniform material like foam blocks)

If so, there’s a greater likelihood of asbestos—and you’re most likely to find this dangerous substance in your attic.

Insulation is the most commonly known asbestos-containing product still present in many homes. Two types of insulation—vermiculite and batt—can contain asbestos, although it’s most often found in the loose-fill style of insulation, vermiculite.⁴

Identifying Asbestos in Your Attic

Although many attics are empty, ignored spaces, some homeowners want to put that square footage to good use. We don’t blame you. A well-insulated attic is a perfect place to store your seasonal decor, clothing, and keepsakes.

So how do you know if it’s safe to put your attic to work for you?

First, we want to be clear that you shouldn’t disturb anything in your attic that you think might contain asbestos. If your attic is finished, look out for ceiling tiles, popcorn ceilings, or other textured paints. These would need to be laboratory tested to confirm the presence of asbestos.

Unfinished attics might have more visible evidence of asbestos.

If the insulation is made from vermiculite, there’s an excellent chance it contains asbestos.
You can identify vermiculite by its appearance. It’s made from small, pebble-like bits. They’re usually about a quarter of the size of a paperclip and are brown, silver, or gold.

Interestingly, vermiculite itself is not harmful.⁵ However, most of the vermiculite used in the U.S. was mined from the same place—a mine contaminated with asbestos.

How to Get Rid of Asbestos in Attics

The idea of asbestos covering your home is disturbing. We want to reassure you that most asbestos-containing materials are only harmful if they’re disturbed or damaged.

If you suspect your home may have asbestos, the best approach is often to leave it alone.

To help you understand, imagine the dandelions that pepper your yard in the spring. Once they turn white, you can blow on them and they release tiny bits of fluff into the air. Think about disturbing asbestos in a similar manner. When left alone, you’re not likely to experience harmful effects. However, when asbestos is disturbed, it releases deadly fibers into the air where you can inhale them.⁶

“Friable” is the term used to describe asbestos that can be crumbled and released into the air. Asbestos is at its most dangerous in this format.

Removal and Replacement

If your attic has vermiculite insulation and you want to remove it, keep in mind that the EPA recommends leaving it alone unless absolutely necessary.⁷ If removing the loose fill insulation is your only option, don’t do it yourself under any circumstances.

If you have no choice but to remove existing asbestos insulation, here are the steps to ensure your safety:

Test the material – Contact a certified professional to make sure you are not dealing with asbestos containing material. If you need help finding one, call your local EPA office. They can point you in the direction of professionals who have completed an asbestos safety course. A professional can take a sample of any material you suspect of containing asbestos and send it to a lab to test for confirmation.
Remove insulation safely – Once your suspicions have been confirmed and you’ve decided to proceed with asbestos removal, a professional will employ what’s known as a negative pressure enclosure. This prevents any loose fibers from escaping and contaminating the rest of your house.
Monitor the air – The contractor who removes the insulation should continue to monitor the air in your home after removal to ensure your safety.
Replace it with new insulation – Today’s insulation isn’t made with asbestos. Consult with a professional to identify the right insulation material for your geographic area, home, and budget.

Other Hiding Spots for Asbestos

While you’re most likely to find asbestos in attic spaces, there’s a chance that other construction materials contain this toxic mineral. If you suspect asbestos in your attic, do your due diligence in inspecting the following areas before you undertake any home renovation projects.

Exterior Surfaces – Asbestos can be found in cement roofing and siding shingles on the exterior of your home.⁸ As long as these are left alone, they’re not likely to pose any risk to you.
Floor and Ceiling Tiles – Asbestos was once used in the adhesive backing on vinyl flooring sheets and stick-on-tiles. Ceiling tiles can also contain asbestos fibers. Pulling up floor tiles can be problematic because you’ll likely scrape the adhesive and release fibers into the air when you remove them.⁹
Textured Paint – Popcorn ceilings aren’t pleasant to look at and they can contain asbestos. The removal of a popcorn ceiling or any textured wall paint containing asbestos must be done by a professional to prevent hazardous exposure.¹⁰ In many cases, it’s better to cover the ceiling or textured paint instead of removing it.
Pipes – Asbestos is commonly found coating hot water pipes in old homes. Old pipes might also be covered with tape that contains asbestos.

What Does Asbestos Insulation Look Like in Attics?

Written by Kevin on August 11, 2021. Posted in Attic Insulation. No Comments on What Does Asbestos Insulation Look Like in Attics?

Lead. Radon. Asbestos. These words scare any homeowner since they indicate serious issues that could lead to expensive home renovation costs.

Toxic asbestos is particularly common in homes built before 1980. Because this mineral is soft, heat-resistant, and relatively inexpensive, it was once a popular material for insulation—particularly in attics. Unfortunately, inhaled asbestos can lead to various long-term health problems including cancer.

So, is asbestos in attics dangerous for your family? What does asbestos insulation look like in attics?

Breathing in asbestos fibers can be a health risk but While it may seem like a burden, the asbestos removal costs far outweigh risking your health. In this short guide, we’ll explain how to identify asbestos insulation in attic spaces and the steps you can take to safely remove this unwanted material from your home.

Identifying Asbestos

First things first: take a look at your attic insulation.

If you have batt or foam board insulation, you’re probably in the clear. Batt insulation comes in a famous fuzzy pink (and in other colors), while foam board insulation is just what it sounds like—boards of foam. In fact, any insulation that comes in uniform sizes that are cut to fill your homes’ unique contours is unlikely to contain asbestos material.
If you have blown-in or loose-fill insulation, asbestos fibers may be an issue. If your attic looks more like a white or gray construction site than a blanket-swaddled chamber, do a little more observation to uncover the likelihood of asbestos.

If you’ve identified blown-in or loose-fill insulation, the next step is to discern whether the fill substance is vermiculite, which commonly contains asbestos exposure.

The giveaway sign of vermiculite insulation is that your attic looks like a gravel path, filled in with a substance with the following characteristics:¹

Particles with a pebble-like shape and appearance
Grey-brown or silvery-gold color, shiny as opposed to other types of blown-in insulation
A lack of paper or another backing to provide it with a uniform structure

Age Matters

Was your home built before the year 2000? Don’t panic!

Since the 1990’s, asbestos insulation has been phased out of use. Research suggests that homes built before the new Millenium are significantly more likely to have asbestos insulation than homes built after.²

This risk becomes larger and larger the further back one goes. For example, a home built in the 1990s is much less likely to contain asbestos material than one built in 1960. It’s important to keep track of insulation age. Replacing attic insulation is very important when the insulation hasn’t been replaced in a long time.

What To Do If You Suspect Asbestos

So you think you might have vermiculite insulation?

While you probably want to take action right away, the last thing you should do is try to remove or replace the insulation material yourself.

Why? Asbestos has been linked to lung diseases including cancer, mesothelioma, and asbestosis. ² And you’re most likely to inhale the fine, toxic particles after disturbing the asbestos, which distributes its dust into the air, contaminating the air quality in your home.

To safely handle asbestos dust, you’ll need proper personal protective equipment (PPE) to protect you from inhaling asbestos fibers. And don’t assume your N95 mask is adequate-if you get particles on your clothes, you could easily transport them throughout your home.

Instead of trying a DIY solution, take the following steps.

Step 1: Leave the Area and Limit Your Exposure

Don’t stand there in your attic Googling pictures of vermiculite.

Immediately remove yourself from the area that you suspect might have asbestos insulation material.

Repeated and prolonged exposure exacerbates the effects of asbestos dust. Therefore:

Refrain from removing or relocating items that are stored in the attic.
Let all household members know about the potential danger.
Keep the door or attic entrance shut until you’ve had a professional assessment.

Step 2: Call a Professional

If you think you might have asbestos, the first thing you need is a professional opinion. It’s still possible that your attic is insulated with another material—and the sooner you know, the sooner you’ll have peace of mind.

If you do need the asbestos insulation in your attic removed and replaced, leave it in the hands of professionals who can safely remove the material while recommending the correct modern material for your home and climate. Removing attic insulation by hand, especially Asbestos removal, can be extremly dangerous when not done properly, so it’s best to call a professional. In general, it’s best to hire a professional for insulation installation and removal, whether it’s fiberglass insulation installation or asbestos removal.
