How Much Does an Asbestos Inspection Cost?

An asbestos inspection costs $501 on average but can range from $143 to $1,744, based on our analysis of 338,754 quotes from licensed inspectors.

If you suspect your home has asbestos, the first step is to get an asbestos inspection. Asbestos is a highly toxic substance that can cause serious health problems when disturbed. If your home was built before the 1980s, there’s a real chance it contains this substance. You’ll want to get it removed as soon as possible.

What is an asbestos inspection?

An asbestos inspection tests a home’s air, dust, and suspicious physical materials for the presence of asbestos. Asbestos is a mineral used for its fire-resistant properties in home materials like floor tiles, insulation, pipe insulation, and asbestos shingles.

When asbestos is disturbed (such as during home renovation), the airborne fibers it releases can lead to extremely serious health hazards like lung cancer and mesothelioma.[1]

Its use in many building materials, such as spray-on fireproofing and insulation, has been outlawed since the 1970s.[2] But it wasn’t until 2024 that most remaining uses of asbestos were finally banned.[3]

If you find out your home contains asbestos, you can have it contained, removed, or (in certain cases) leave it in place. You should never attempt to remove asbestos on your own. Justin Chau, a realtor in San Gabriel, California, says, “Homeowners should avoid trying to DIY remove asbestos as harmful chemicals are involved. They should instead contact experts.”

How much asbestos inspections cost

The national average cost for an asbestos inspection is $501. However, the cost can range from $143 to $1,744, depending on factors like location and type of testing.

Factors impacting asbestos inspection costs

If you have a very large house, the testing locations are inaccessible (e.g., behind a wall or under a floor), or if the inspector has to travel a long distance, then your asbestos inspection could incur additional fees.

Factors that can increase the cost of your inspection include:

Types of testing

There are three main types of asbestos tests: air, physical sample, and dust. Each test has its own fee, and you may need multiple testing kits.

• Air testing tests a home’s air for the presence of asbestos using a special air filter. It can cost as little as $200 or as much as $800, depending on how large your home is.
• Physical sample testing is the most common type of asbestos test, costing $250–750. It involves removing samples of suspected materials (like insulation or pipe covering) and sending them to a lab.
• Dust testing requires the inspector to wipe dust from around your home. It usually costs $120–$180.[4]

Size of your home

Larger homes take more time to inspect and may require more individual tests to cover all areas suspected of contamination.

Market location

Busier markets with more demand for inspectors will drive up inspection prices. However, if your home is in a remote area, the inspector may charge extra for travel time.

How accessible the inspected areas are

The inspector may need to access areas like the crawlspace and attic, or even underneath floors or inside walls. If they have to pry up floorboards or open walls to access the testing site, they’ll likely come with an extra fee.

Asbestos inspection costs vs. other inspections

Signs you might need an asbestos inspection

Asbestos can be found in many building materials, especially those used before the 1980s. There’s no obvious way to tell whether or not a home contains asbestos without contacting a home inspector.

As Casey Callais, a residential inspector at Constructiva Inspections in Austin, Texas, says, “Any good inspector must be trained on what to look out for when inspecting a house that may be old enough to have asbestos. It is most often seen in exterior siding tiles but also can be found in older popcorn ceilings, linoleum tile, and vermiculite insulation. If the inspector calls it out as a possibility, it needs to be evaluated by professionals such as an abatement company.

If you’re buying or selling an older home, getting an asbestos inspection is a good idea just so everyone understands present and future risks. Buyers want to know if they’re on the hook for expensive remediation if they decide to renovate in the future, and it’s a big advantage for sellers to tell buyers that their home is asbestos-free.

Although asbestos can be incredibly toxic, undamaged asbestos materials are generally harmless. If you have intact asbestos-containing material in your home, and it’s in good condition, it’s likely not a health hazard, and experts suggest just leaving it alone.[5]

What happens during an asbestos inspection?

An asbestos inspector will mainly sample the air and dust of your home and send it to a lab for evaluation. They’ll also take small samples of any materials they suspect may contain asbestos.

Before the inspection, they’ll turn off your HVAC system to prevent the circulation of disturbed asbestos and cover the area with plastic sheeting to prevent contamination. After they sample any suspected asbestos materials, they’ll repair and seal the damage to avoid continued exposure.

Because disturbed asbestos is so dangerous, the inspector will likely ask you to leave the house during testing. Asbestos particles are microscopic, so an asbestos inspection isn’t like a conventional home inspection that involves an inspector looking at parts of your home.

The asbestos inspector will look at areas and materials that they suspect may contain asbestos, such as:

• Shingles
• Textured paints and finishes (e.g., popcorn ceilings)
• Insulation
• Pipe coatings
• Floor tiles, backing, and adhesives
• Protective barriers and gaskets around furnaces and wood-burning stoves

After your asbestos inspection, the inspector will prepare a detailed report on their findings, including any lab results.

You should receive this report within 1–3 days of your inspection. Ask your inspector about timelines for the tests they plan to use to make sure that results will arrive fast enough for you.

My home has asbestos. Now what?

While undamaged asbestos materials aren’t dangerous, their presence does mean that you won’t be able to renovate without doing expensive asbestos removal first. If you’re buying a home with asbestos, you may want to ask the seller to remediate the asbestos before the sale proceeds.

Removal

If you want the asbestos removed, you’ll have to hire a certified asbestos abatement pro. They’re specially trained to safely remove the asbestos, dispose of it, and leave your home uncontaminated.

It's safest to leave the home during asbestos removal, so it might be most convenient to have the remediation done after the seller moves out and before the buyer moves in.

Alternatively, you could get an estimate from an asbestos removal service and negotiate a price credit to do the removal yourself. Don’t worry if the seller refuses to remove the asbestos or even pay for the service — you still have options.

If you opt to remove the asbestos, a certified asbestos abatement pro can do so for an average of $2,238:

• Indoor asbestos remediation: $5–20 per square foot
• Exterior asbestos remediation: $50–150 per square foot

In extreme cases, whole home remediation can cost over $5,700.[6]

Containment

If you feel comfortable leaving the asbestos in place, you could opt for a process called containment or encapsulation. This involves coating the asbestos materials in your home with a special adhesive to prevent the asbestos from spreading through the air.

Containment is often the safer option, especially if the asbestos material is in good condition and unlikely to be disturbed. Removal, especially if done improperly, presents a greater risk of asbestos fibers being released, which poses a major health hazard.

But if you’re planning on remodeling or making major changes to your home that are likely to disturb the asbestos material, you’ll probably need to hire an asbestos removal expert.[5]

Containment is 15% to 25% less expensive than removal, costing about $2–6 per square foot, and can be done relatively quickly.[6]

How to find an asbestos inspector

Asbestos inspectors have to be specially trained and certified by the EPA. Always confirm that your asbestos inspector has the necessary licensing and certification.

You can ask friends and family for a referral to an inspector they’ve used. Many real estate agents will also be able to connect you with a dependable local asbestos inspector.

If you can find multiple asbestos inspectors in your area, get multiple estimates to get the best price. And always check online reviews.

Key questions to ask your asbestos inspector:

• Are you EPA-certified?
• How much experience do you have doing asbestos inspections?
• Is it safe for me to stay in the house while you conduct your inspection?
• How much testing do you think I’ll need, and how much will it cost?
• How much does the inspection cost, and what is included?
• What areas of my home might harbor asbestos?
• Do you have access to all the areas you need to test?
• How long will it take to get results back for the asbestos tests?

The bottom line

Finding asbestos in a home you’re buying or selling isn’t necessarily a deal-killer — but it is a serious matter. You need to establish if the asbestos is contaminating the space, and the first step is getting an asbestos inspection.

While a basic asbestos inspection costs an average of $501, costs can quickly add up if you need a lot of testing. Your safety is worth it, though, as asbestos can be extremely dangerous.

Never try to remove asbestos material yourself, no matter how expensive it is. Leave it to the trained experts.
