Percolation Tests FAQs, answered by experts

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

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. 

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed.
