1900 semi detached house, external south west facing first floor corner, this room was plastered and decorated three years ago and now this. Any thoughts on what I need to do? We're likely moving a three year old in here soon, so OH is keen for some action. Cheers.
Worth bearing in mind these problems can come from above. I've had a couple of them where the problem turned out to be weeping radiator joints on the floor above. Took a long time to find it, in the mean time I had stripped the plaster off and replastered with a waterproof filler.
