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.

It's okay to live in a house with asbestos siding as long as it's intact. Asbestos siding in good condition poses minimal risk since the fibers remain bound. If the siding is damaged, or deteriorating, or if renovations are planned that may disturb it, the risk of exposure increases significantly. Consult a professional asbestos inspector to assess the situation and provide recommendations.

It can be safe to live in a house with asbestos as long as the asbestos-containing materials are in good condition and not disturbed. Asbestos is only dangerous when it becomes airborne, which happens if the material is damaged, crumbling, or disturbed during renovation work. If you suspect asbestos is present, it's important not to disturb it and to have it professionally inspected.

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

It is strongly advised not to touch or disturb asbestos-containing materials unless necessary. Asbestos fibers can be released into the air when the material is damaged or disturbed, posing serious health risks if inhaled. It is best to leave any handling of asbestos to trained professionals who can remove the asbestos safely.
