I recently put fitted wardrobes into my bedroom (wall to wall). Since this has been done, I am finding my shoes have white marks on them, some of my clothes are starting to have mould marks. The wardrobe has not been lined and is next to an outside wall (actually the wall of an old coal shed). I have started leaving the coal shed open thinking this would help to circulate the air, but the walls of my wardrobe are always cold and they are starting to have little mould patches. I didn’t have a problem until the fitted wardrobes were installed. Will this be rising damp or condensation? Please note I live in the bottom floor flat and it’s a very old building.
