Percolation Tests questions, answered by experts

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.

Asbestos was most commonly produced and integrated into building products from the 1920s to the late 1980s. In reality, asbestos use should have ceased much sooner because asbestos was linked to cancer in studies produced as early as the 1950s. You can even extend that number past the 1980s due to stockpiled materials and because some countries treat asbestos use differently. It may also be found more in commercial applications than residential.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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.

Costs depend on the number of samples, property size, and lab processing fees.
