Asbestos Testing Cost by Test Type
The cost of an asbestos test includes several elements, including a visual inspection, sample gathering, sample testing, and a report on the findings. Sometimes the source of the asbestos contamination is obvious and a professional can begin by testing a direct sample. Other times it is difficult to determine the extent of an asbestos contamination or its source, so a local asbestos testing pro will essentially need to start from zero, testing everything.
Here's what you can expect to pay for asbestos testing by test type:
| Type of Asbestos Testing | Average Cost Range |
|---|---|
| Air | $200–$800 |
| Dust Sample | $120–$180 |
| Physical Sample | $250–$750 |
Air Testing
Testing the air in your home for asbestos usually costs around $500 but can be as low as $200 and as high as $800, depending on the size of your home and the extent of sampling required. Your inspector will take a sample of the air in your home using a special filter, and then they will send it to a lab so technicians can check for asbestos particles.
Dust Sample Testing
Dust sample testing usually costs between $120 and $180, including labor. Your inspector will gather dust that has settled in your home for testing and send it off to a lab for evaluation.
Physical Sample Testing
You can expect a physical sample test—the most common type of asbestos testing—to cost between $250 and $750. A professional will come to your home for testing and collect several samples (for example, scraping off part of a popcorn ceiling or removing some insulation from pipes). They will send the physical samples to a lab, and technicians will analyze them and report back with results.
Asbestos Testing Cost Factors

A few different factors can impact how much your asbestos test will ultimately cost.
Home Size
More materials need to be inspected and tested when a property is larger. This includes air testing. In a larger home, you could need air tests from several areas. It becomes expensive when there is contamination spreading through the house by way of a ventilation system, often requiring the entire house to be tested.
Accessibility
Easy access means a less expensive asbestos test. If the inspector cannot easily get to the items that need testing, this can drive up the price. Testing for asbestos in a basement with an old gravity furnace is easy. Performing the same type of test in the space between the attic and the roof, less so. These pros will add a hefty surcharge if the inspection requires any alterations to walls or floors.
Location
Your geographic location will impact the cost of an asbestos test. Here are some average prices in cities around the United States:
| Location | Average Cost |
|---|---|
| Seattle, WA | $200 – $770 |
| Los Angeles, CA | $210 – $530 |
| Phoenix, AZ | $190 – $550 |
| Bridgeport, CT | $310 – $870 |
| Wilmington, DE | $260 – $660 |
| Atlanta, GA | $220 – $600 |
| Indianapolis, IN | $200 – $300 |
| Minneapolis, MN | $180 – $370 |
| Denver, CO | $190 – $380 |
| Nashville, TN | $170 – $990 |
In addition to asbestos testing costs varying by city, an inspector may also charge more if you are far away from them or live in an out-of-the-way rural area.
When to Have Your Home Tested for Asbestos
Asbestos tests confirm the presence of asbestos so you can figure out which steps to take to remove it. Tests are most effective when performed during times when there is likely to be a high concentration of airborne asbestos. You will want to test if you suspect your home contains asbestos materials, before (or sometimes after) doing any sort of renovation that will require demolition, and possibly prior to buying a new house as part of the general inspection process.
If evidence points toward asbestos, such as finding a warning label or being confirmed by a previous owner, testing is a logical response. The main reason a homeowner would want to test for asbestos during any sort of demolition work is to avoid disturbing material and causing asbestos to become airborne, posing a severe health risk.
Where Is Asbestos Commonly Found?
According to Angi customers, 31.1% of homeowners have had their ceilings tested for asbestos, and 16.8% have had insulation throughout their home tested. Other common areas for testing include drywall and siding. It’s important to test for asbestos throughout your home to prevent serious respiratory problems, so call an asbestos removal company for professional testing ASAP.
Why You Should Hire an Asbestos Testing Pro
Hiring a professional asbestos testing service may cost more upfront, but you benefit from accurate results, safe handling, and peace of mind. Professionals have the expertise and equipment to detect asbestos without putting you or your property at risk.
Here’s why it’s ideal to hire a professional asbestos testing service
Asbestos testing requires careful sampling, proper containment, and lab analysis to ensure accurate results. Here are some of the top reasons to work with a pro:
Testing specialists ensure samples are collected safely without contaminating your home or exposing occupants.
They have the training and tools needed to properly handle and transport samples for lab analysis.
Working with a professional ensures you get reliable results and clear guidance on next steps, whether removal or monitoring is needed.
Bundling asbestos testing with inspections, home renovations, or removal services can help save on overall project costs.
If you want to DIY some prep tasks for asbestos testing
If you’d like to handle minor prep work yourself to save time and labor costs, here are a few tasks you can take on:
Clear the area where testing will occur, removing furniture, appliances, or personal items.
Note visible areas of concern, such as damaged insulation, ceiling tiles, or flooring, to guide the testing process.
Ensure pets and children are kept away from the area during testing to maintain safety.
Next Steps: Finalize Your Project With an Asbestos Pro
Be prepared to discuss with a pro the areas of your home you suspect may contain asbestos, as well as the type and condition of materials, since this affects testing methods and safety precautions.
If your budget allows, ask your pro about optional services such as full-home inspections, air quality testing, or clearance testing after removal.
Make sure the areas to be tested are accessible and free of clutter, since proper sampling requires direct access to surfaces and materials.
Plan for potential unexpected costs, including additional sampling or lab analysis if initial results indicate widespread or high-risk asbestos presence.
