Percolation Tests FAQs, answered by experts

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Professional asbestos testers or environmental consultants are the best people to call to test for asbestos. An asbestos testing company specializes in collecting and analyzing samples and will be the most qualified to do the job for you. An environmental consultant may not specialize in handling asbestos, but should still have the knowledge and know-how to safely collect a sample and send it off for analysis.

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.

Testing and analysis take 10 days to 2 weeks. Expedited services are available for urgent situations typically requiring higher fees.

While asbestos can’t be directly absorbed through the skin—the fibers are too big—skin contact can still produce symptoms. Contact dermatitis can flare up in sensitive individuals but in most cases, the danger from asbestos comes from inhaling the fibers, or dust, that is produced when asbestos is disturbed. If you touch asbestos by accident, immediately wash yourself and your clothes.
