Hi, we live in a flat and a few days back our washing machine started leaking. We only discovered it when downstairs flat owner came to say that there is a leak on their ceiling and walls. We've paid for leak repair and now have to pay for redecoration of that flat and I accept this responsibility. The dispute however is about the cost of repair - they invited the painter without agreeing the quotation with us and having done a quick check I have a reasonably lower quotation for the same job. Our insurance doesn't cover 3rd party damage so have to pay cash. Where do I stand in terms of disputing costs? if it makes any difference, it's not a council block.
