Can anyone give me any advice please? I have a back to back property that has had damp issues. It has a damproof course. About 3 years ago we had the chimney condemned, we were using it for a gas fire. We had the chimney capped and decided to have an electric fire instead as it's only used very rarely. I have noticed an increase in the damp. We installed trickle vents in the windows to improve the air circulation. The chimney breast is inbetween the houses on an internal wall. I have been to the property today and removed at least 3 layers of plaster of varying depths. The base coats were very damp and the exposed brick also feels damp. I have had my roofer check the stack and he said the cap and the pointing are ok. Can anyone tell me if this will be contributing to the damp throughout the property (2 up 2 down) and if so could anyone please tell me whst could be causing it!! Many thanks, Joanne.
