Asbestos testing costs $250 to $850 on average. The visual inspection alone costs $100 to $500 and testing costs about $20 to $80 per sample, so the size of the area and the number of materials being tested have a big impact on the cost. A certified inspector visually assesses the area, takes samples for testing, and provides a report with the results. If the report finds asbestos, the inspector will also provide recommendations for how to move forward.
An asbestos refurbishment and demolition survey costs $600 to $1,500+ and is required before any renovation or demolition projects. This survey tests all potential asbestos-containing materials in space.
There are several types of asbestos tests:
Strongly consider testing for asbestos in the following situations:
Undamaged and undisturbed asbestos-containing materials (ACM) are not dangerous. However, when the ACM is disturbed, hazardous fibers become airborne and dangerous. If you suspect your home contains ACM, leave it alone and contact a certified asbestos contractor to inspect and test it safely.
Asbestos is tested in a lab using methods that detect the fibers microscopically. Sample requirements differ depending on the laboratory, but most labs request a 1" to 2" square for materials like ceiling tiles, drywall pieces, or flooring material. For dust and other materials, labs typically ask for about 1 tablespoon or a quarter size amount.
The most common methods for asbestos testing are:
You can collect samples for testing yourself with DIY kits that cost $50 to $250, depending on the number of samples. However, due to the dangers and serious health risks associated with asbestos-containing material (ACM), it's best to hire a certified professional to inspect, test, and report.
Most home inspectors do not test for asbestos, but they typically will alert you if they see suspected asbestos-containing materials in the house. Some home inspectors may offer asbestos testing as an extra service for an additional cost if they are also trained and certified to provide asbestos inspections.
Asbestos testing takes one day to several weeks for the lab testing. Most labs offer tiered pricing based on how quickly you need the results. An asbestos inspector typically spends 30 minutes to 3+ hours collecting samples, depending on the area size and the number of materials being tested.
Due to its associated health risks, asbestos is highly regulated, and testing should be conducted by a qualified professional. Follow these guidelines when looking for an asbestos testing company near you:
