I have moved into my flat 6 months ago and have noticed a damp patch slowly getting worse in my bathroom. The bathroom has 9" solid brick external walls and the damp patch is on a wall that the next door neighbours have a shed next to. The shed has a sloping roof with no gutter and is positioned about 6" from the wall.
What are your opinions on whether this could be causing my damp patch?
