We lost some guttering at the beginning of the year due to the heavy snow and at the same time had a wc on the external wall replastered.
We did have some damp come through the new plaster to the external wall and as gutters had been replaced and the externall wall had dried out, I used some stain block and decorated.
However, we now have damp back and the wall does feel slightly damp - the cause of the damp is definitely resolved.
Is my only option to solve this would be to hack off all the plaster back to the stone wall and replastered?
