Percolation Tests FAQs, 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.

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

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.

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.

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.
