Hi all, I recently bought my first house and after a few months living here I noticed some water damage in my living room, which backs onto my ensuite. I have had a look behind my wall through the powerpoint and a vent in the wall and could see mould growing. I think there may have been a leak at one point because I can see a few patches on the wall and maybe they didnt let it dry fully before closing it up.
I would like to have a go at removing the mould and water damaged bits myself. The picture attached shows where the mould is growing behind the wall.
my question is, how far up and how far around the shower do I have to remove? My concerns are mostly about waterproofing especially in the corners where old and new villaboard would meet.
Also, any tips on this kind of project or dealing with mould would be appreciated.
