Percolation Tests questions, answered by experts

Many homeowners may never have to test their homes for asbestos. Asbestos particles are only dangerous if they become airborne. If you plan to do construction or notice damage to piping, siding, or drywall, you should hire a specialist to test for asbestos.

If you plan to remodel your home or have any concerns, you should have your home tested for asbestos just to be safe.

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.

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.

According to the Environmental Protection Agency (EPA), you should contact the following officials to report a case of asbestos exposure:

Asbestos subject matter experts in your state
EPA regional office
Toxic Substances Control Act (TSCA) Assistance Information Service Hotline via mail, email, or phone
EPA’s Asbestos Ombudsman via phone or fax

If asbestos is found, it is crucial to consult with a professional. They will provide recommendations for appropriate abatement actions, which may include safe removal, containment, sealing, or enclosure. All actions must be planned and executed in accordance with local regulations for handling asbestos.
