Since our neighbours had their fascias and guttering done when it rains it is like a waterfall coming off our gutter and leaving water to gather on the ground. The problem is that the drainpipe is at their side of the houses (we're in semis) and the guttering on their house is not at a significant drop to clear the water away it's straight all along. When we have had someone to look at it he advised that the water is just gathering between both houses and therefore causing overflow when it rains. The neighbours will not fix this so what is the solution. We have no grid at our side to clear the water away to if we put a drainpipe in. I even thought of getting a water butt! Any thoughts?
