Hi
I have recently had the floor joists changed at my front door as they were rotton the property is 1920 s and apparently this is a common fault.
When the workman took the skirting off so he could replace the floorboards a large peice of the wall fell off. On closer inspection there was a large area that was powdery to the touch and was loose from the wall.
I live in an upstairs flat and there is only a single brick wall between mine and nextdoors hallway. Nextdoor say they have no damp however they do have wood panelling. There is no heating at the front door the only heat being the radiator at the top of my stairs
I have took all the loose plaster off and am now left with about a square yard of brick, its cold to the touch but not wet.
What is the best way to repair this wall?
Cheers
Dora :D
