Hello,
I have some damp issues with my flat and I wonder if you can give me some advice.
1) Flat above leaked into my bathroom and the wall is very wet, wallpaper is coming off and mould is growing. Some part is so wet, the plaster has turned liquid. The flat above has stopped the leak but what do I need to do to fix the walls? Is drying the wall and replastering enough?
2) A corner of the bedroom is showing some black mould rising from the floor to the ceiling. The flat is on 2nd floor so surely, this can't be rising damp? I have cleaned the wall before and painted with damp seal before wallpapering over. But this has now come back. What can be the root of this?
Many thanks in advance for any advice you can give me!
