Percolation Tests FAQs, answered by experts

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.

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.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.

Asbestos testing takes place in two stages—collection and lab testing. Collection can take less than 20 minutes if a professional manages to get a direct sample. If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.
