Percolation Tests questions, answered by experts

Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.

Costs depend on property size, test types, and additional services like mold sampling.

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.

Through air sampling devices and surface swabs in key areas of concern.

Asbestos itself does not typically leak from a roof. However, if an asbestos-containing roof is damaged or deteriorated, it can release asbestos fibers into the air. This can occur when the roof is disturbed, such as during maintenance or repairs, or due to weathering over time. Exposure to airborne asbestos fibers can be harmful to health, so it is important to address any damaged asbestos roofs promptly and safely.
