Husband found a radiator pipe leaking. Turned it to stop the leak but accidentally opened it, causing black crap to explode all over newly painted walls & carpet. Called our insurers for advise and was told not to clean the carpets but to dry as much as possible and await call back within 48 hours. Never receive any call within 24 hours. Just checked my email with one plain email saying we aren’t covered on our accidental policy as diy or faulty workmanship aren’t covered. We’ve left carpets as advised so no the black crap has well n truly dried in and now they say we aren’t covered!! Any advice. I feel totally fleeced by the insurers 😡
