Sorry. I have a couple of patches of damp in the kitchen. The first is very strange. It is at the bottom corner of a completely internal dividing wall.
The other side is showing no signs of damp, but i suspect this is because it has been painted with a few layers of silk paint.
Where is this damp coming from? A couple of thoughts are 1. The damp course (injected) has failed, but can damp really get into an internal wall in this fashion? 2. The damp course is sound but water is leaking aove the wall and settling on the damp course. Less likely i think.
The other damp patch is on an external wall. It starts behind the washer and dishwasher and has extended out to the wall alongside.
When i originally discovered this damp patch there was a fence post attached to the house outside. When i took that off, much of the mortar was missing behind it, so I repointed the whole corner and reattached the post. However this hasn't sorted the problem, in fact it is getting worse.
How long can you expect an injected damp course to last? Im not sure how old this one is, but most of the plastic caps have gone from the injection holes. Is it possible to have it redone? Would this need the plaster hacking off inside? And how much would this cost? The house has solid walls.
The reason I am anxious to sort it now is that the house is on the market and short of offering the surveyor sexual favours, he will spot the damp and the buyer will insist on a discount. I'd rather sort it out myself.
