Damp Proofing Question
Damp through external wall
Hi guys i need some advice. I noticed paint bubbling up from the external hallway wall on the side of the window when i tried rubbing the paint off the wall i found a patch of damp area on the wall it seems to get worse when there is heavy rain..think its the pointing that's gone outside can anyone shine some light on this and best solution for this??
The best thing to do is to have a damp test conducted to see if the damp course has failed. A local builder should come and have a look with a damp meter for free. If the damp course has gone the plaster inside is usually hacked off to the height of 1 meter. Then re-instated when it has dried out and the damp course has been fixed. It would also be a good idea to re-point any areas that need doing. Hope this helps, James - Bricks and Mortar.

It might be the pointing, or if it's below the window, it might be the window cill has perished and needs fixing/sealing.
