About 18 months ago we had new upvc gutters,soffits and fascias fitted to replace old asbestos. We employed a contractor who did an excellent job he fitted deepflow gutters to match the council owned property to our right (we are mid terrace.) All was well until our opposite neighbour decided to have hers done. There have been a number of issues we have had to contend with but our main concern is that they have fitted standard gutters.
To join this standard gutter to our deepflow they have cut notches out of our gutter and squeezed it into standard joints is this an acceptable method please advise
