Live in a terrace. Next door man is a bit grumpy he lives alone as do I so I have to deal with him
Anyway rainwater is coming into my hall and stairs upstairs causing damp and mould
My builder had a good look and the leak is from mr next door’s broken roof tiles - no idea if he’s got damp too We both own our houses as far as I know
Except neighbour won’t engage He’s not interested in fixing it
Any ideas what I can do ? Who to speak to to make him get it sorted?
