Wondering if anyone can help me. I've noticed an increasingly bad damp musty smell coming from behind my cabnets in my kitchen next to the washing machine. I thought there might be a leak from the pipe leading into it and called a plumber round. He pulled the machine out and everything was intact. On the wall behind the machine was mould that looked like black soot. We touched the wall & everything was bone dry. No sign of any wetness. He said everything looked fine. Also it didn't appear that the smell was coming from behind the washing machine after all. I am currently unable to use the drawer which is situated next to the washing machine because the smell is so bad when I open it. The smell is localised in this area, I can't smell it anywhere else. I don't know what my course of action is. Do I have to rip off the cabnets & floor tiles to see if I can source the cause or is there a less destructive means? I'm in a ground floor tenement flat with a basement space underneath. Could there be rising damp and would this only affect one area? The wall in question is an interior wall between the kitchen & bedroom. Argh! Help.
