Ok it sounds bad, but has anyone bought an old house with these problems? The house is part early 19thC and part 17thC. The cellar is airy and smells ok (not damp), brick floor, but floods a bit when the water table rises. I could live with that with a sump pump maybe? The other problem is the house doesn't have foundations the way modern houses do. Plenty of old houses were built like this, it's a good solid house, no damp, loads of similar properties around here with people living in them, and it's been there for centuries. I've renovated 19thC houses before but nothing this old. I'm in a bidding war for it. Any advice from anyone who's actually done this?
