Hi - I have recently replastered a chimney breast (6 months ago) after buying a new flat. The chimney itself has been removed and the "open" stack lies just above the room in the loft space. I can actually look down the stack from the loft.
There are about three patches of damp appearing (not wet - just stained) two near the ceiling and a third about half way down the wall. The wall itself has a couple of vents at the bottom, so there should be ventilation from the room into the loft space.
How should I resolve this please?
