Damp at base of walls - Help!! It's confirmed a few things we've already thought of and suggested a few new ideas. I also tell a lie about the survey. I completely forgot to mention that we had a surveyor out to do a report on that crack you see at the bottom of the window, since it came up on our mortgage survey. The problem was found to be a leaking sewer down the side of the property, which was saturating the ground water and causing very slight movement. It's all been rectified now, but no other source of damp was mentioned at the time. I may give the guy another call and get him to come out again.

The damp seems to spread out from that exact area, and it has only happened since we've had the heavy rain.

My thoughts are that the DPC could have been put in as a solution to this, which is why we saw evidence of damp having been there, but none recently. The place was dry as a bone when we moved in.
