You can’t identify asbestos by looking at it. Only scientific testing of a sample can confirm asbestos. Follow the golden rule: if you think it might be asbestos, treat it like it is asbestos.
If you’re renovating, repairing or demolishing a building that may contain asbestos, get a sample tested before you start work. It is cheaper and easier to deal with asbestos if it isn’t a surprise.
Sealed asbestos that is in good condition is low risk. Asbestos is a risk if damaged, weathered or disturbed.
Use a professional to take a sample and get the material tested.
Two groups of people can test samples:
The results should be on a Certificate of Analysis endorsed by the National Association of Testing Authorities (NATA).
The cost for scientific testing of asbestos at a NATA accredited laboratory is between $40-$140.
