Hi. There's a wall in my house that has damp at the bases. I had a dpc put in and had it replastered with lime plaster which has helped somewhat. I also had a radiator put it, which may have helped. However, the damp problem is still there in one wall particularly. This is an extension adjoining a kitchen. Either side is a concrete floor. I suspect the floors are bridging the DPC. Also, the external wall was rendered, not really allowing the damp to go anywhere. I want to sell up but I know the survey will say "damp" mercilessly! Is there anything I can do. Could the floors be cut away from the floor to stop the bridging? Any ideas gratefully received! Thanks very much, Ed.

It’s difficult to say without seeing it, but the damp proof course could be too low. You may benefit from another damp proof course being a bit higher to stop the concrete floor bridging the DPC. Also, we would need to have look to see if the brick work is porous where the wall was rendered, because it could be allowing rain water to penetrate through, causing internal problems. We would be happy to come out to do a free survey to assist you further.
