Percolation Tests questions, answered by experts

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.

Even a single, one-time exposure to asbestos can be harmful and pose health risks. According to the EPA, any contact can increase the risk of developing asbestos-related diseases and certain types of cancer, although the likelihood of severe health issues increases with repeated or prolonged exposure.

The severity of a single exposure depends on factors like the duration, intensity, and concentration of the asbestos fibers. While a small amount is less likely to cause significant damage, a high concentration can lead to serious long-term lung damage. Individual reactions vary, and asbestos-related illnesses may not appear for 10 to 40 years after inhalation.

Given these risks, always take precautions around any material suspected to contain asbestos. Personal protective equipment (PPE) may not be completely effective. If you suspect asbestos is in your home, hire a professional for testing and removal. If you are worried about a potential exposure, consult your doctor.

It is not recommended to drill into asbestos siding because doing so can release hazardous asbestos fibers into the air. The safest way to handle asbestos-containing materials is to have a professional remove or encapsulate them.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

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.
