I have a terraced house with a cellar. For 2 years it has been dry with an occasional slight smell of damp. About a month ago it filled up with about an inch of water. Over the weekend I dried it out completely, but this evening water has started to flow in through the party wall, about 4 or 5 litres in half an hour. I went next door and asked the lady if her cellar is dry. She went to look on her own and pronounced it dry. I'm not sure if I believe her.
What do I do? The water is definately coming from the party wall on her side. Will the buildings insurance investgate this? What does the party wall act cover?
