The recent weather in NY has caused me some water damage. Trying to decide what needs to be done. The house is a 1960's split level. The damage is in the foyer and half bath that is at ground level. Some water seemed to be pooling up from below the floor and seeping in around the floor tiles there. At first I wasn't sure where it was coming from. I was worried there might be a crack in the foundation, or that it was coming in under the sliding door to the back yard. Right next to this area is a part of the house that includes a basement. The basement has a sump pump. The first thing I did was to get a plumber to examine the pipes and pump and he found a problem there. It seems likely that the pump was not operating properly and some water was spraying out of the pipes inside the house, which then soaked the basement wall and the ceiling and therefore the floor above. I fixed this and the leaking has stopped, but that area was drenched and I can see and smell mold. What are the steps I need to take to repair this type of a problem? I am thinking I probably need to tear up that floor and completely redo that bathroom.
