My council house has a water heater in the bedroom. It must have been leaking for a long time because by the time I noticed the kitchen ceiling was soaking wet. When the council came round the riped part of the ceiling down and all of the wooden joists and ceiling were moldy! They have replaced the boiler and patched the ceiling up in the kitchen! Only problem now is I get a really bad smell in every room downstairs. Mainly the living room. Could this be the mold? Its driving me mad! Thanks.. all the best Mart
