Although the inspector appeared thorough during the walkthrough, the final report feels disappointingly vague. Many sections include phrases like “Limited View” or recommend “further review by a specialist” or “professional testing by another party.” I expected that by hiring a specialist, the...

Percolation Tests questions, answered by experts

While it's possible to cover asbestos tile with carpet, it's not recommended. Encapsulating tile beneath carpet doesn't eliminate the health risks. Over time, the asbestos tiles could degrade, releasing fibers into the air and potentially contaminating the carpet. Disturbance during carpet installation or removal might also release fibers.

Clear the area for access and inform the testing team about the building’s history and renovations.

Some pros may recommend covering a popcorn ceiling that tests positive for asbestos with beadboard ceiling planks or drywall. The cost to install a beadboard ceiling averages more than $5,000, but you likely will pay more than the average for the installer to deal with the asbestos safely. Installing a beadboard ceiling or new drywall will disturb the asbestos and release some microscopic fibers, so the installer will need to take precautions.

Epoxying over asbestos tiles is generally considered a safe option when done correctly. Epoxy acts as a sealant, encapsulating the asbestos tiles and preventing the release of asbestos fibers into the air. The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.

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
