We live in a mid-terrace built in the early 1900s. It has had a damp proof course treatment and this appears to be working effectively. Our problem is in the upstairs bedroom and the front room.
• Upstairs there is a brown stain that that runs vertically down the wall.
• Downstairs in one section of the living room wall (vertically) the plaster has bubbled and if you wipe the wall a powder residue comes off on your fingers. This is only 1.5 meter section width over the whole wall 5 meters.
Both sections of the wall (upstairs and downstairs) are along next doors chimney breast. Our house does not have a breast remaining. Next door no longer use a coal fire, but instead have an electric one in place. They don’t appear to have any problems on their side but its wall papered so not sure if this hides a multitude of sins?!
The chimney stack was removed last summer, and the roof retiled and sealed. We left it 6 months took the plaster off to the brickwork and then re-plastered and painted. However a year on we’re back in the same nightmare.
Someone has suggested that this could be next doors salts coming through. However this doesn’t explain upstairs to me.
I’m sick of throwing good money, time and effort at this wall please could someone advice as to what we should do.
• What do you think it is
• How to resolve it
Whilst it’s tempting to wall paper it I’ve a feeling the brown stain would penetrate anyhow.
Thanks in advance
