Percolation Tests FAQs, answered by experts

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

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

The Environmental Protection Agency (EPA) banned the use of asbestos pipe insulation in certain applications in 1975. It released further bans in 1989 and 2019. While asbestos pipe insulation was common from the 1930s to 1970s, its use fell off after the 1970s due to public concern and the EPA's actions.

No, not all popcorn ceilings have asbestos, but a vast majority do. The Environmental Protection Agency (EPA) banned its use in 1973, although it still may have been used up through the early ‘90s. But, in general, homes built or remodeled before the early ‘80s likely utilized materials with asbestos. That being said, a professional test is the only way to determine for sure.

Most manufacturers stopped putting asbestos in linoleum before 1980 due to public concerns about its toxicity. However, the Environmental Protection Agency (EPA) didn’t ban asbestos-containing products until 1989, and a comprehensive ban was not announced until 2024. This means that homes built after 1989 may still have asbestos in their flooring.
