Percolation Tests FAQs, answered by experts

Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.

Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing.

The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.

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

In the event of suspected or confirmed asbestos contamination on the body, it is imperative to take immediate measures to reduce health risks. To avoid further exposure, carefully remove contaminated clothing and shower thoroughly to remove any asbestos fibers. Seek prompt medical attention, and inform your healthcare professional about your suspected asbestos exposure. Since asbestos-related health issues can take years to surface, regular medical check-ups are advised for anyone with a history of exposure.

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.
