The only sure way to know if your home or property contains asbestos is by testing its material in the lab. There are some clues that may warn you that your house is asbestos containing. Older homes built in the 1920s through the mid-1970s are most likely to be asbestos containing. Asbestos can be found in ceiling stipple, window caulking, plaster, drywall joint compound, vinyl flooring, cement, and shingles.
