Percolation Tests questions, answered by experts

Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.

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.

Professional asbestos testers or environmental consultants are the best people to call to test for asbestos. An asbestos testing company specializes in collecting and analyzing samples and will be the most qualified to do the job for you. An environmental consultant may not specialize in handling asbestos, but should still have the knowledge and know-how to safely collect a sample and send it off for analysis.

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.
