Noticed some damp starting to form at the top of one of my bedroom walls a few months back, investigated further and found it was a result of nextdoors chimney, next door have removed the top section of the chimney but the damps starting to comeback.
I’m thinking the lower section could do with some re-pointing + there’s no covers on the top so any waters going in and running down (its unused as a chimney so never dries out)
Popped up into the loft again just now, the very top internal brickwork and cement is dry, lower down the cement is almost wet, you can scrap it off with your fingers, main solution is to sort the chimney but once done is there anyway of speeding the drying process up of the wall? Dehumidifier? the attics well vented as it is.
The damp on the walls has never dried out due to the amount of damp in the brickwork above, its not something that has ever recovered once it started.
Neighbours….its doing my head in! If it were my chimney I’d have had it sorted the week it started.
Balls! wrong forum!
