Mark did a good job, he put the damp proofing in. Unfortunately it did not solve the problem. He suggested getting the drains fixed at the front of the house, so we did this. That didn't solve the problem either. We then got a roofer in , he thought the water was coming down the chimney, so we are trying to fix that now. It seems that no one really knows where the damp is coming from ! We were pleased with what Mark did, it just didn't solve our problem.
