Hi,
I have noticed a run of external bricks which are quite damp (so damp that moss is growing on them). This is a run about 2 bricks wide running the vertical length of the wall (which is a bout a single storey, as it is above our side return roof). Pictures attached.
This is our bathroom wall. Internally, a large mirror, about 4 feet long, is glued (I think) to the other side of the wall. There is a gap between the wall and the mirror at the top.
We have an odd problem internally above the mirror, where a brown sludge appears on the paint work. It can be wiped away, but it soon returns.
I am wondering whether the wall behind the mirror has become damp from condensation when we shower/bath, and the plaster is wicking the damp to the external brickwork. Is this possible?
(I can't see what else might be causing the problem).
I suppose the mirror needs to come down (which doesn't seem like much fun) so I can take a better look. If that is the problem, what should I do?
Many thanks.
