The wall separates to rooms and is not on the outside of the building, my house has recently been surveyed by the people that are about to buy it and i have been told that there is a possible damp problem, can anyone please help me as to where this damp patch may have come from. The floors of the house are timber with a 3ft void beneath that, so i cant see that it can be rising damp as the floor/walls do not come into contact with the earth below. I had the cavity wall insulation installed 12 months ago and was wondering if that will have affected ventilation. If anyone can help i would be really grateful

The damp patch is just above the skirting board on a ground floor, i have had a roofing problem about a month ago but this was on a chimney stack and no where near where this damp patch is. The wall paper is coming away from the wall as well. I dont have a condensation problem in the house at all, and this seems to be the only wall affected, the central heating pipes run under the floor. im at a loss as to what it might be

new air bricks where fitted at the same time as the cavity wall insulation was done im wondering if it is a ventilation problem, i have been told before that cavity wall insulation can sometimes make things worse.

how big is the damp area? how damp are we talking? whats the weather been like since you noticed the area in question? does the wall border any bathrooms or kitchen or utility? have you had any remodelling done lately? have you hung any pictures run any screws or nails into the dry wall and possibly put a pin hole puncture in the plumbing? a roof leak? is the entire wall soaked up and down?

I am not sure if your house is 2 levels or just a single level house, but when roof problems occur any leakage can often appear in places a long distance from where the actual roof problem was. The water travels along rafters and then will drip on to other things like electrical conduit and show up in the most pecular places. Other things that can cause this type of damp is a leaking pipe in the attic or in the wall. Again if the leak is in the attic it can travel a long way and appear in what you would assume to be an unrelated spot.
If you can I would cut open the wall at the damp spot and investigate but chances are you wont see anything much unless the leaking pipe is there. If you are sure the problem has been fixed then path the hole up with sheetrock and it should stay dry.
good luck.

We had this problem in our house about the same age. It was the ventilation under the floorboards. Try clearing the crap out and sorting out the airbricks so theyre not blocked. Make sure air can flow to the walls and also check for leaking pipes/radiators that may be the cause. This'll save you thousands from a dampproof course that may not even fix the problem.

It COULD be condensation if you live in a humid area but this time of year I think a leaky roof is more likely.

If you can, go under your house and look up at that spot, see if it is wet or damp, if so, the damaged parts will have to be replaced.
It happened to us.
