Percolation Tests FAQs, answered by experts

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

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.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.
