I am having problems with leaks and now mold in our house. The landlord has refused to fix saying it's just a cosmetic fix. I'm not sure why mold which is now growing on the ceiling is considered cosmetic. I've even had the local council in who said I should just wash it with bleach. Perhaps being American I am just not used to this - mold is serious to us and seems the norm here. Is it my responsibility or the landlord? Thanks!!
