Hi all, I have a bit of a problem!
I've recently moved into a 1970's semi. In the last couple of months the wall surrounding the chimney breast on the first floor seems to have developed rather a large amount of damp:
I understand the previous owner had the lead flashing around the chimney replaced fairly recently (you could see a small amount of recent water damage around the unplastered chimney in the loft), but the wall in question looks like the paint is a couple of years old. I had new loft insulation installed right before it started, but I don't think this is to blame as the chimney is damp above the loft insulation (by testing with a damp meter).
I do have an oil boiler that I believe is vented through the chimney.
I have just started to strip the paint as mould has started to appear, and the damp seems to go all the way up, and is now starting to affect the (artex) ceiling, which I REALLY don't want to touch! The walls on the other side of the chimney are mostly wallpapered so its harder to see the damage.
Looking from the ground, I can't see a chimney cap, could this be the cause with all of the recent heavy rain, or does it look like something else?
If I find the root of the problem and sort it will it all dry out, or am I likely to have to replaster?
Many thanks in advance for any help!
