When Inspecting old homes I often come across interesting methods for shoring up sagging floor joists.
There aren’t many things worse than walking across your basement, and suddenly getting your feet wet. Maybe the kids spilled something on the carpet or Fido had an accident. Then you realize there is a lot more water there than either could produce.
The gray, (and sometimes pinkish), stains below the surface of the vinyl flooring around your toilet may indicate water damage. When there are stains around your toilet, there is probably a leak in the wax seal ring that seals the toilet to the plumbing flange at the floor. Continued leaking over a period of time will rot the flooring under your toilet and eventually leak into the ares below.
Floor squeaks are caused by loose floorboards and framing members that move and rub against each other as you walk across the floor. The noise comes from wood rubbing on wood or wood rubbing on nails.
