We have a big ivy problem. Our side return and wall of our house (end of terrace) backs on to another garden where a right funny (not haha) chap lives. He has an ivy which has grown right up over his house obscuring one of his windows and right up our wall and is working its way into our chimney. We really need to get rid as it doesn't help our winter damp problems and could be working into the mortar between the bricks. I've knocked a few times to ask him to cut it down but he's not been in and as it is covering his whole house and garden, I don't imagine he's too bothered. Can we ask him to pay to get it dealt with? Whose responsibility is it? Don't want to be stuck with a massive bill because he hasn't kept his foliage trimmed. (Snort)
