Percolation Tests FAQs, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

When learning how to test for asbestos in a popcorn ceiling, you have an option for a DIY job or to hire a professional tester. You can purchase a kit at a hardware store and use personal protective equipment while doing the test. If you don’t want to risk any potential exposure to asbestos, hire a professional asbestos testing company instead.

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.

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

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.
