Cost To Insulate Garage

The average cost to insulate a garage is $4,500, according to BobVila. Prices will typically range from $2,000-$6,000 in the U.S. Let’s look at a few factors below that could impact the total cost.

How Much Does It Cost To Insulate A Garage?

Homeowners often choose to insulate their garage areas for numerous different reasons. One of the most common reasons is to reduce energy needed to heat and cool the home. Other homeowners may choose to reduce noise in the garage that invades other areas of the home. Adding this insulation can also increase the value of one’s property.
Insulating a garage is a common investment, with an average price tag of $4,500. Larger spaces or complex installations can cost more than $6,000 total. This guide will go over installation, benefits and how to save money on this project.
Here are the typical costs of garage insulation:
  • Lowest Cost: $2,000.
  • Average Cost: $4,500.
  • Highest Cost: $6,000.

Garage Insulation Cost

Garage Insulation Cost Factors

Many factors go into figuring out the exact costs of insulating garage doors, walls and ceilings. These factors are outlined below.

Garage Size

Size of the garage is undoubtedly the most influential factor when estimating the cost of an insulation installation. Typically, a bigger garage will call for more insulation. For instance, it will always cost more to insulate a 600-square-foot space than a 400-square-foot space.

A small, single car garage (average of 240 sq. ft.) will cost between $572-$6,600 for installation. Two-car garages can end up costing anywhere from $780-$9,000. Three-garages, meanwhile, can cost up to $15,000, depending on insulation type and material.

Type Of Insulation

There are five main types of insulation that homeowners will choose from, with many individuals opting to mix and match types in order to best fit the space. However, mixing and matching insulation types can result in a wide range of costs.

Batt insulation is always the cheapest option, costing anywhere from $0.65-$2 per sq. ft. This insulation type is usually used for both walls and ceilings. Rigid board insulation is known as the most expensive option, with costs ranging from $5.75-$15 per sq. ft.

Insulation Material

There are nine standard material types used for insulation. These types include fiberglass, cellulose, blue jean, sheep wool, wood fiber, rockwol, polyisocyanurate, cork and polystyrene. Fiberglass is one of the cheapest options, while cork and polystyrene are the most expensive. These materials can range all the way from $0.40-$15 per sq. ft.

Insulation R-Value

R-value is a term that many homeowners will not be familiar with, but it is important to know when installing insulation. R-value measures how resistant a material is to transferring warmth. Higher R-values will keep in heat more effectively.

The R-values of the different materials mentioned above range from 2.2-7. Spray foam has the highest R-value, but it will also come with the highest price tag.


Location of the installation will influence the price, of course. Accessing some areas could require more time and effort, meaning additional labor hours will be tacked on. Garage doors are easy to access and insulate, which results in the lowest cost of any part of the garage installation.

Homeowners should expect to pay $500-$700 for the door installation. Floors will cost between $600-$900 to insulate, while ceilings cost a bit more, ranging from $260-$3,000. Walls typically cost the most to insulate, with costs expected between $780-$9,000.


Labor is one final piece of the total cost of this project. Labor costs are dependent on material and type of insulation. Typically, labor will cost $300-$4,000.

Additional Cost Factors To Consider

Some garage insulation installations will come with unexpected costs. Homeowners should keep the following items in mind when budgeting for insulation:
  • Energy audit.
  • Soundproofing.
  • Installing drywall.
  • Weatherstripping.
  • Mold remediation.

Cost Of Garage Insulation Types

All garage insulation types offer different advantages and price ranges. Let’s breakdown the common types of garage insulation right here.


Batt insulation is commonly referred to as “batts” or “rolls”. This type utilizes a flexible blanket-like insulation that is best suited for easily accessible areas. Batts and rolls can be used in non-standard areas, so the material will have to be cut to size.

The blankets come in high, medium and standard-density constructions, made from fiberglass, rock wool and other similar materials. Batt insulation can be fitted quite easily to the specific areas, but it may be hard to fit in unusual or hard-to-access areas.

  • Average Cost: $0.65-$2.00 per sq. ft.


Blown in insulation is constructed of either fiberglass or cellulose that is blown into cavities in walls. This material is used to fill gaps in the insulation. Blown in insulation is ideal for attic spaces filled with nooks and crannies that are difficult to navigate through.

Cellulose blown in insulation is the most affordable option for home and business owners because it is made of recycled materials. Once it is installed, this insulation can last up to 25 years with very reliable performance overall.

  • Average Cost: $1.65-$3.80 per sq. ft.

Foam Board

Foam board is very popular but be sure to check out the R value of any board you are using for maximum efficiency. You have to choose the right thickness of board to ensure it seals properly so it is effective against vapor. Depending on local building codes you may need board that is two to four inches thick.

  • Average Cost: $2.40-$3.75 per sq. ft.

Spray Foam

Spray foam insulation is unique in that not only does it act as an insulation barrier, but expands into tiny gaps and cracks.  This seals off many of your home’s air leaks, to keep you cooler in summer and warmer in winter.  Open cell spray foam expands to an incredible 100 times its original volume in just seconds.

The primary components of spray foam are an organic chemical compound made from petroleum extracts and water.  It is mixed and blown onto the inner wall and attic surfaces to seal the home and insulate it.

  • Average Cost: $3.15-$7.50 per sq. ft.

Rigid Board

This can be an expensive choice for garage installations. In fact, rigid board is only recommended for garages that are waterproofed or completely finished since it’s not water-resistant. This is a good soundproofing material, though, and that’s why some homeowners choose this type.

  • Average Cost: $5.75-$15.00 per sq. ft.


In areas like Arizona radiant barrier insulations are especially effective. Many homes have their cooling ducts running through the ceilings and attic areas. In these cases keeping the attic cooler is absolutely critical in having an energy efficient home.
Radiant barriers alone can reduce energy costs as much as 5-10%. Using a radiant barrier in combination with another insulation type is a great way to maximize the homes thermal efficiency and reduce energy costs year long.
  • Average Cost: $700-$2,900 total.

Insulating A Garage

Benefits Of Garage Insulation

If you often spend most of your time in the garage than what it takes to leave your car and go inside, then an insulated door, at the very least, needs to be on your shopping list. Modern garages often tend to serve as not only a parking space, but a craft room, rec room, workshop, and a showplace for your cars and much more.

Based on the time of year and your climate, you may want to heat or cool your garage to make it more comfortable. Your garage is one of the biggest rooms of your home, so why not maximize the use. If you cool or heat your garage, then you need an insulated garage door to minimize heat transmission through the door and keep your costs for cooling and heating lower. Whenever you combine the benefits of insulated garage doors with an organized garage, you will have endless possibilities.

Energy Efficiency Of An Insulated Garage Door

Insulated doors have a lot of benefits for attached garages. The insulation in the home reduces transmission of heat into your garage, and the insulation within the garage door limits that transmission even more. If your garage door isn’t insulated, then that is a barrier that keeps your cool or warm air in, and one less barrier to get money from your wallet.

Even if the garage door is insulated, if there aren’t proper door seals in place, then you may be costing yourself money. The most common seals are the threshold, bottom, and weather stripping. These insulating devices are inexpensive and simple and can provide comfort and save your money.

Less Noise In Your Home

If you have an attached garage and a living space above or next to the garage, then insulated garage doors will offer noise buffering. Just like insulation keeps in the cold out and the heat in, insulation also keeps the noise out as well. If you live next to a noisy neighborhood, then you should consider an insulated door.

Stronger Garage Doors

Your garage door strength will depend on the rigidity and strength of your construction material and how it was constructed. For instance, a single layer steel door isn’t as strong as an insulated door with triple or double layer construction.

The double layered garage door is normally made of galvanized steel with polyurethane or polystyrene insulation on the inside. Even though it is called a double layer, it actually contains a third layer of plastic or vinyl on the inside for cleaning ease and looks.

The triple layered garage door will sandwich insulation between 2 layers of wood or steel. The outer layer can be created to match your home, and the inside is smooth. The higher R-value and highest soundproofing come with this strong garage door option and it is the ultimate insulated garage door.

DIY Or Hire Professional For Garage Insulation?

This can be a DIY task, as long as you know what you’re doing when it comes to installing insulation. Knowing exactly how to insulate this area, though, often requires years of experience. In most cases, hiring a professional for the job is the more cost-effective option.

  • Your utility knife will be able to cut through the boards quite easily.
  • Place the rafters on the left and right sides of the garage, just like the insulation.
  • Use a staple gun and ladder to install the vents on top of the rafters.
  • You will need one staple for every 8-10 inches for security.

Step 4. Prepare Insulation

  • Place your insulation outside of the garage at this time.
  • Use your utility knife to cut the insulation so it fits between each rafter.
  • Place pieces of identical square footage to the left side of the garage.
  • Place the perimeter pieces on the opposite side of the garage.
  • This will help you from spending too much time searching for each piece.

Step 5. Install The Insulation

  • Install the insulation you placed on the left side of the garage first.
  • Install it in the rafters below the rafter vents.
  • You may be able to push it into place if you have batt insulation.
  • Align the front of the piece with the rafter front so the back of the insulation faces downward.
  • Rigid foam can face either direction.
  • Grab the irregular perimeter pieces of insulation, placing them between the rafters.
  • After insulation, check the entire ceiling for any gaps.
  • Fill any gaps with leftover pieces of insulation and rafter vents.

How to Tell The Difference Between Cellulose and Asbestos Insulation

With asbestos still being used as a very commonly used fire retardant and a very popular insulator right until the end of the 1980’s. It was very versatile, affordable and it could be used in tiles and blow it with another material, vermiculite.

Differences Between Asbestos And Cellulose Insulation

Before we review the differences between asbestos and cellulose insulation, it is worth comprehending the properties regarding each of these materials.

Asbestos Insulation

Many people do not know that asbestos is, in fact, a natural mineral. asbestos is in general terms flexible and soft but also has great corrosion resistant and heat resistant properties. From the early 1950’s for a period of nearly forty years, the construction industry used asbestos as an insulator and fire retardant. When you view older buildings and houses, you will still find asbestos in drywall, tiles, tile grout and in the attic. That being said, so long as there are no damage or wall cavities exposing asbestos fibers in the living areas of the property, it is deemed to be safe. However, it becomes a very serious health hazard when asbestos particles become airborne and are able to reach the areas of the proeprty you occupy.

Cellulose Insulation

As an asbestos alternative, cellulose insulation is made from many different materials including cardboard, hemp, straw, newspaper, and many other different materials. When a paper-based cellulose mix is utilized by builders, it is treated with something called boric acid to give it fire resistance properties.

The two most common forms of cellulose insulation include dry cellulose and that is also known as loose-fill insulation. Builders will use a blower to blow the cellulose into the wall through holes. it can also be used to fill wall cavities. Wet spray cellulose is something builders use to apply to walls that have been newly constructed. The primary difference between dry cellulose and wet spray is that water is added during the spraying process. it provides a better seal for the prevention of heat loss.

Like asbestos, cellulose works well within pipes, walls and around wiring. it assists in both suppressing fires and both insulating your home. Cellulose also utilizes material that is recycled and that is a big advantage for owners of buildings looking to go green.


So now you understand the differences in the ingredients, they do look very similar when they are inspected. Although it is a different insulator, there are similar issues with vermiculite attic insulation as it is a very difficult proposition to see whether asbestos is contained within. The best thing to do is not to touch it but obtain the services of a professional to extract some samples and get a confirmation as to whether it contains asbestos. If asbestos is contained, you will want to seriously consider instituting a program of asbestos management or to completely remove the asbestos.

What To Do Next

When more than ten square feet of asbestos, you need the services of a professional abatement company. When you are handling larger projects, there is an extremely high risk of exposure and contamination not only to you but also those around you.

The professional contractor will quickly and safely remove the asbestos and with the set-up of barriers surrounding the work area to prevent tenants from coming into contact with asbestos. Reverse airflow will be used to keep the asbestos fibers from spreading. They will then wear equipment with special protective qualities and cleanse the area with HEPA filter vacuums and then properly dispose of the asbestos.

Does Fiberglass Insulation Need To Be Covered?

Does fiberglass insulation need to be covered, or is it safe to leave it exposed? The answer depends on how you use the space where the exposed fiberglass is located. You often see that homes have exposed fiberglass insulation in the basement or attic. Pink, fluffy batts wedged tightly between studs, rafters, and joists insulate the space against exterior temperature changes Read on to learn more!

Fiberglass Insulation In Spaces That Are Unoccupied

Builders leaving fiberglass insulation exposed are in compliance with building codes because as long as the insulation is undisturbed. The American Lung Association agrees. This means if your attic or basement with exposed fiberglass insulation is used for storage only, there’s no need to change anything.

Exposed Fiberglass Insulation In Occupied Spaces

What if the previous owner of your new home used the unfinished basement for storage, but you want to convert it into a gym or playroom? In this case, even if you don’t plan on completely finishing the basement, you should cover the exposed fiberglass insulation for safety reasons, including disturbing fiberglass insulation can send particles into the air that act as lung, eye, and skin irritants and children playing around exposed fiberglass insulation may touch or even eat it, which can be a serious risk to their health.

Covering Fiberglass Insulation

If you decide to cover fiberglass in an occupied living space, make sure you choose a permeable barrier that won’t trap moisture. This allows your home to breathe more easily and helps prevent mold growth. Suggestions for covering exposed insulation include working with an insulation expert to ensure safe, code-compliant results, installing plywood flooring over the floor, installing sheetrock or paneling over the walls and sealing the insulation by stapling a polymembrane sheet on top of it.

Asbestos Insulation Removal

Asbestos removal may become an issue when a material contyaining asbestos is damaged, crumbling or flaking in your home. Read on to learn more about what to do and the costs associated with the removal of asbestos.

Asbestos was used very widely in building materials before the start of the 1970’s. In reality it is actually a carcinogen but can often be found in older buildings among pipe and duct ventilation, vermiculite attic insulation, wall and ceiling acoustic tiles, cement floor tiles and siding as well as floor tile adhesives.

However it is wise that is the asbestos containing materials are in your home are undamaged, leave them alone. According to the Environmental Protection Agency it is far more dangerous to disturb them. In fact in the majority of states you must disclose if asbestos is in your home prior to its sale. But if you are planning a remodel, removing the asbestos will be the best thing you can do if you are going to disturb it in any way.

Asbestos Removal Basics

The first thing to do is to have the material you suspect containing asbestos tested and then have it professionally removed.

  • Speak with the asbestos program in your region as well as the asbestos administrative department in the state where the property is or you can contact OSHA (Occupational Safety & Health Administration) regional office to establish the local regulations and requirements for your area.
  • Find accreited asbestos contractors and inspectors who are trained and licenced in the testing and removal of safe asbestos.
  • Conflict of interest can be avoided by having suspect materials tested by a certain company and the removal completed by a different company.
  • Preparation is key. It may be the case you and your family will have to move out of your house on a temporary basis while the asbestos is being removed from the property.

Getting A Contractor

There is nothing infra dig about using a flooring, siding or roofing contractor for this as long as they are trained and well practices in the removal of asbestos. Before the commencement of work, you will want to ensure you have a written contract clearly expressing the local, state and federal regulations the contractor is obliged to follow including the clean up of your premises and the disposal of the asbestos. At the end of the job, get written evidence from the contractor that the above procedures were completed correctly. Have a licensed asbestos inspector perform a follow-up check as a final step.

Asbestos Removal Costs

An initial inspecton for asbestos costs an average of $600 with prices ranging from $400 to $800 for the US in 2019.

Asbestos removal costs do vary depending on how much needs to be removed. But you can expect an average minimum fee of $2,250 with averages varying on the low to high end at between $1,500 and $3,000.

Total asbestos removal in a home measuring 1,500 square feet with asbestos in the floors, walls, ceilings, pipes and roof averages $25,000 with costs ranging from $20,000 to $30,000 for the US in 2019.

What R-Value of Insulation to Use for a Garage?

A lot of people usually don’t think of insulating their garage when they are insulating their house but doing so goes a long way in reducing energy costs for the whole house as it offers an additional buffer.

Insulating the Garage

When you have a room built over a garage, it becomes vital to insulate the ceiling of the garage to avoid the heated area above it from losing its heat. When you insulate your garage, use insulation with the exact same rated R-value as that was installed in your home’s ceiling and walls.

While insulating your garage won’t make it essentially warmer unless you include a heater, it will help to provide additional insulated space for the home. A great deal of people enter and exit the home through their garage, the additional insulation will help make the car start easier in the morning. Use the same insulation to insulate the garage that was used for the exterior walls of the home. If the walls and ceiling are closed in, think of using a loose fill type of insulation, as this type of insulation uses a machine to push the insulation where it needs to go through a hole in the sheetrock. Insulate the garage’s ceiling by using the suggested R-value for your area as advised by the Department of Energy.

Exterior Walls

If your exterior walls were constructed from 2-by-4 inch studs, the maximum insulation that can be installed into the wall while keeping its R-value is R-13 or R-15 as these are each made to fit a recess at a depth of 3 1/2 inches. Because insulation fits the width and depth of the recess between studs, when you condense insulation to fit the space, you take away its insulating properties — the trapped air between the fibers.


When you have a room over your garage, its floor rests on boards supported by joists. If the joists are 10 inches deep, the recess can take high-density R-30 insulation, which is 8 1/2 inches thick, more than adequate enough for floor insulation. If the rafters are open to the garage, (boards that support the roof) use R-38 insulation between the them at the roof, if they are at a depth of 10 inches. To add additional insulation inside the garage, using sheetrock install a ceiling and allow access to the space between the new ceiling and the roof. This allows you to add the required insulation. While some ceilings in the southwestern part of the United States require a minimum of R-19 insulation, most attics or ceiling areas require a minimum of R-38 in the ceiling.

Garage Door Insulation

Use specialized foil-backed blanket insulation to fit the inside of your garage door. A lot of garage-door insulation has an R-value between R-8 and R-12, because it is thin enough to fit the space. This will add insulation to the garage door without hindering its functionality. Another option is purchasing a pre-insulated garage door that might have a higher R-value. If you insulate the garage without insulating the garage door will allow any heat collected in the room to escape through the door.

Best Way to Insulate Garages

When insulating your garage, it’s up to you to determine what type of insulation material works best for your garage.

Your overall goals and expectations and what they are will help you choose the insulation that works best in your situation. If you need a conditioned space that will keep cold air out of your home or extra room, a material that creates an air barrier will benefit you most.

Cellulose and fiberglass insulation don’t provide the kind of air barrier you are looking for in this scenario, so a foam insulation is a better alternative.

Insulating A Garage

Although we associate Arizona with heat, for most of the year we have a warm to cool climate. We insulate our homes but insulating a garage is important too. Read on to learn more!

Shared Walls

With the majority of garages only sharing a single wall with the house, the roof of the garage can retain large amounts of heat and that heat may get into your home, causing an increased burden on your cooling system.


Reducing heat is key. A garage roof, often with eaves and peaks together with attic space, it should be relatively simple to get in there you can install fiberglass batt insulation and when the roof can be seen, you can apply some high R-value board between the joists.  Closed-sell spray foam may be applied, though would need the services of a professional company for maximum efficiency.

Carbon Monoxide

This killer gas can be a killer and other gases in your garage can harm the health of your family. The correct sealing of he living space to the garage space is crucial. Some builders use a cavity wall system acting as a return duct for the air in the HVAC – not a good idea! When you insulate walls, you will need the services of a professional to make sure the air flow is correctly rerouted.
