I've recently begun researching asbestos because I think that our siding is the old asbestos shingles. No problem there, I know it's pretty safe. However, I tend to freak out, and I've started remembering some things that might be a problem. Most recently, when we had satellite television set up, the installer drilled a hole through the shingles, right into our living room. Would that be enough to have caused problems? More worrisome is something I worked on about 5 years ago. I stripped wallpaper off from one bedroom, and the walls were all different--one wall was wood planks, one looked like plaster, and two were something that I couldn't identify. It looked sort of like concrete, but it was softer--almost kind of crumbly when I scraped the paper off with a putty knife. I covered everything with joint compound to texture it and cover over all the differences between walls (looks awesome, if I do say so), but now I am wondering if that crumbly stuff was asbestos. Now, I do tend to get myself worked up in a tizzy, so I keep telling myself to calm down. However, without knowledge, the mind goes to bad places. So can anyone help me? Am I guaranteed to leave my children motherless? Looking for common sense, not professional medical opinions!
