I've just had a large chunk of ceiling in the hall come down. Happened while the house was unoccupied. No apparent reason. It's the original lath and plaster. Had it been a normal flat ceiling I'd just have replaced it with plasterboard - but this is the bit that goes under the stairs so is a complex shape in places. And is way beyond my skills.
Is this the sort of thing I could claim on the house insurance for? Or just fair wear and tear?
