We live in a Terraced house and our bathroom outside wall is on next doors side as are most on the street. There isn't an option of an amicable conversation, which woukd obviously be the furst option but sadly this wont happen. There guttering is leaking and splashing up onto our rendering which was re done 6 years ago and quite a large cost. They also have a large tree that is pushing our fence and the roots have pulled up our garden path. I contacted out home insurance and said the guttering issue won't be covered if it damages our rendering as its rainwater and Sainsbury's dobt cover anything in regards to rainwater. What are my options? Is there a formal way to get things resolved? Thank you for reading x
