Sorry that this is a boring one...
I live in a downstairs flat conversion and our upstairs neighbours have been there for 3 years. Before they moved in we had issues with water pouring through the ceiling into our bedroom which ruined bedding and ceiling but they dealt with it and assured us it was fixed - it happened about 3 times.
So, this evening I was putting the baby to bed when water started pouring through again, it dripped on the duvet and a cushion before I could get a bucket. I immediately told the lodger upstairs who said he’d been running a bath and would stop. The owner is away but I left him a message and he called back pretty quickly. His lodger had filled him already in so he knew that this had been an ongoing issue and he went on to say that the previous owners had completed many botch jobs that are slowly coming to light - including the patch job of this leak. He was very apologetic and said he would be happy to share any costs with me when he gets back. I didn’t agree or disagree to this but said I would call back with more information later.
My AIBU is even though the previous owners did shoddy work, surely he should pay for the plumber and other damages as the leak came from his property?
