Percolation Tests questions, answered by experts

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.

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.

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
