A friend has a 33 year old brick ranch with a full basement.There are cracks in the basement floor, and the linoleum on the floor in one section is lifting, and the floor under it is lifting...3-4 inches. She had some-one come out and they said something about "pirex" (not sure of spelling), and told her to call her insurance co. The insurance company said it's not covered. She had water in the basement a few years ago, and had the drain tiles replaced in a section of the house. She was told it was not a water problem, but that there was mold under the floor. But mold comes from moisture and darkness, doesn't it? Why would her floor crack and come up like that? Someone told her it would be a 10-12 thousand dollar repair job. What should she do, and who should she call for help??
