I have a bedroom in the eves of the loft, it is like a square box with one wall that is on the outer wall with a window and the two side walls are just plaster board with a stud wall into the landing with a door in it, the loft has been insulated but the walls that are the bedroom have not, the loft is not damp and there are no leaks from the roof but the bedroom walls are always wet and develop black and grey marks, I have washed the walls but it keeps on happening, I don't understand where the wet is coming from, HELP
