It is possible that the trim sustained some damage, the subfloor was definetly stained. I never thought to try and paint it before laying down the hardwood. Yes I think I do notice it more on humid days, even though my house is airconditioned and generally very dry.
OK- So last October I bought a house and there was wall to wall carpet in it. I go into the dining room and there is a portion of carpet cut out exposing the plywood sub floor. I only need to get 3 feet away to discover why...the smell of cat urine was overwhelming. Well we bought the house...
