I am starting to get worried about my mother-in-law. She has been having problems with her sewer lines, and every time she uses her washer it backs up into her laundry room. Her carpet has gotten soaked several times, and it is even starting to seep up the drywall. Already I am smelling mold down there, and I sure hope it’s not black because black mold in houses is extremely toxic! She has got to get those sewer lines fixed, and after that she needs to get someone in there to test that mold. I would hate to see her start to have health problems.
