I purchased my first home 4 weeks ago and had been removing my basement tile when it was brought to my attention that they might be aspestos. I had them tested and they are. I cannot afford $5. per square ft. to have them removed. What is the safest way to go about doing this myself or should I just cover it with carpet and leave it undisturbed? I've already removed approx. 50 tiles myself with no mask or gloves and a fan on. How bad is this stuff?
