Dampness in Wall

pmking_uk · 23-06-2008, 16:55

There are 'streaks' gradually appearing at the top of part of my kitchen wall by the ceiling. The plaster is starting to flake. The bathroom is above the kitchen but I can't find any obvious signs of leaks after lifting a floorboard. There is some damp but can't work out where it's coming from. Any suggestions? Photo's should be attached. Thanks.

Hey PMking

Its really hard to tell because your pictures dont indicate any orientation, and they are really really small.

On the wall with the cracks, is that an outside wall too, and is it a cavity wall?

If it is, can you take a big picture of the outside wall?
