internal wall - that was external has 2 spots where the paint work has peeled - any ideas?

is the affected wall a cavity wall? if so something bridging the cavity and allowing damp to track or allowing damp dripping down the cavity a bridge across to the surface? Presume side of wall in pics was originally outside? then a cavity tie, if fitted properly, should have been fitted to slope down across the cavity to assist and damp to drain *out* of the building and not inwards.. Such a tie could have a big dollop of mortar from alterations stuck across it too making a bigger better bridge for damp to concentrate on?

hope it helps Jim

In the corner, behind your wine rack unit, is there an old vent through the wall? It looks like damp is getting onto the plaster surface, but not from through the wall. Like condensation in the room gathering at the door opening. It could be coming up from the floor, but would imagine seeing it climb up the wall from the skirting, which it doesn't look to be doing that, from what I see in your photographs.

It is low down on the wall, so it's either climbing up or dripping / running down the surface or right behind the plaster. I know this is going to far, but have looked behind the skirting to see if it is damp behind there?

That's the only things I can glean from the photos'. Unless I come down and have a look for myself, I'm stuck. :-)

As a general cure-many, a simple option is to use oil based undercoat for the patch. Emulsion and oil paints are permeable to different things, and susceptible to different things. After that you might or might not emulsion over it ok.

Thank for all the info.

I am thinking its down to the cavity wall. There is a pipe that runs though the wall - behind the baskets and into the utility room and this is in line with the issues.

The sides of the wall, the other side in the utility room, lower down do feel cooler than the top half. The skirting is held on with grabit sealant and I would have thought if there was damp, the sealand would have lost grip.

There though is no damp in the utility room. Nothing on the walls and been round them.

I am also thinking that maybe there was a air brick at some point and the hight could be about right. The lino floor in the utility room has been pulled up due to the leak and this issue only seems to be in one area which just happens to be in a corner that is on a external wall.

Nto sure how I can fix this but I am thinking of having the external walls filled with cavity filler.

thoughts?

Get the damp sorted out before even thinking down that road any further.

That's my thoughts too.

You say a utility room on the other side of the wall. Is there a tumble dryer in the room? If yes, then is it vented to the outside of the house? It's just that where the damp sort of patch is forming is just a nice height for either rising damp or condensation gathering in humid room. Which normally happens beside and on windows or low down next to and on doors and doorways.

It could also be a pet rubbing themselves against the wall on the way out the door. It's a nice height for that as well. :-)

Thanks everyone

Well, I have found the issue. Pulled out a cabinet today thats at the side of the main wall, and guess what - leaking pipe. Its dripping down onto the side of the wall, and soaking up the wall. I think the wall insulation that I put round an opening has absorbed alot of it.

Just stripped it, dried as much as I can.

Only noticed it as I decided to pull up a piece of kitchen cabinet kickboard. Thank god I did. Looks like it may have started as a small drip and got worse.

Stripped as much as I can out of it and will now hopefully monitor it as it drys.

Fingers crossed it drys all ok.

Saves you checking for self-abusing animals... :-)

Good - when its dry, look at insulation.
