Any ideas what could be causing this damp patch?
It's on the top stairway heading up to the attic (which was converted into an office before we bought it)
It first appeared a few months ago and hasn't got any bigger (in fact it starts to recede a bit when it's dry & warm..)

Anyone else had anything similar??
