Percolation Tests FAQs, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Clear the area for access and inform the testing team about the building’s history and renovations.

The cost for asbestos testing typically ranges from $400 to $800. The final price depends on several factors, including the number of samples needed, the size and age of the property, and the professional's expertise required for comprehensive testing. Larger or older properties may have higher costs.

Although the use of asbestos has declined since the 1980s, it remains in several different types of building construction materials for insulation and as a fire retardant. Typically, asbestos can be found in materials such as ceiling and floor tiles, heat-resistant fabrics and coatings, and roof shingles. You may also find asbestos in textured paint and patching compounds.
