Chiswick & Fulham Roofing in London

I engaged Nick Flynn trading as Chiswick and Fulham Roofing to replace front and back guttering on a 3 storey Fulham terrace house. First place time it rained water poured from all joins at both front and back. It turned out he had fitted incompatible, wrong size guttering. This was an appalling job and Flynn’s response completely unprofessional. I would not touch the guy again with a barge pole.
