Percolation Tests questions, answered by experts

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.

You can tell if old flooring has asbestos if thick black flooring adhesive is underneath the tiles. However, homeowners should not cut into linoleum floors to look for this adhesive. Instead, hiring a specialist to test the floors is the only safe way to determine if old flooring has asbestos.

It is not recommended to drill into asbestos siding because doing so can release hazardous asbestos fibers into the air. The safest way to handle asbestos-containing materials is to have a professional remove or encapsulate them.

If your home was built before 1989 and still has original vinyl, there’s a high probability of asbestos mixed into the old flooring, which can harm you and your family if it’s disturbed from removal. If you suspect that you have asbestos, you’ll want to call in an asbestos removal expert to evaluate the situation.

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.
