卖家给的解释,请各位给个意见:The closet was never repaired for water damage. The patch work done was for running an internet/TV cable to that room from the basement. For some strange reason, only one small spot registered a high moisture reading with no clear water marks. My contractor had opened up the wall and did not discover any visible water leaks. He did not take any photographs as it was not necessary. The closet has now been re-patched and repainted. Additionally, I have given a 6 months warranty on it. A new moisture-reading has not been done. Possible reason for a higher reading could be because of a weeping/breathing hole/brick at that particular spot or just a route of some draught in the walls. There is no physical water leak and we should not be overly concerning.
