I am really stuck for what to do with two walls in my bedroom (which are also outside walls). The room has had a constant problem with rising black mould appearing in the corner of the room and along the bottom of both walls.
A few years ago, someone stripped the old wallpaper off, put up a foil lining on the original wall and wallpapered over it. It worked for a while but the mould had now been back for a couple of years. Last year I got a new window installed, I'm hoping this will have helped the problem, becuase when the old window was there it had thick condensation appearing every day, now there is none.
I am left with a corner that is stained with black mould, and when I peel away the wallpaper I can see the black mould growing underneath. I know that I should remove the wallpaper because it is bad for my health as I am sleeping there, however, I am worried that when I remove the wallpaper I will be left with the silver foil and won't be able to paint over it. I can't afford to hire a tradesman right now, so I'm not sure if I should just remove the mould from the current wallpaper and seal it in?
Hi basilpot2020 Firstly, you need to have the bedroom window open at all times to reduce the moisture content in the room Secondly, short term you need to run a de-humidifier in the room to reduce moisture adsorbed in the room fabric Thirdly, you need to remove the paper and foil and redecorate with a breathable paint and treat the mould as it appears. If your bedroom walls are solid it is unlikely that you will cure this problem. Regards S
