Percolation Tests questions, answered by experts

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.

Asbestos testing is conducted by collecting samples from materials suspected to contain asbestos and analyzing them in laboratories for confirmed presence.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Testing is crucial to identify harmful asbestos fibers common in building materials from older properties, ensuring safe environments and health.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.
