Customer Reviews

Faced with a slab leak and the knowledge that further slab leaks could occur even if we fixed this one, we had David Gray Plumbing come out and re-pipe our entire house. Their quote was a bit higher than what we received from some of the other teams who came around to assess the work but we were convinced that they would be faster, more thorough, and take greater care. They completed the work in two full days without a hitch. I would recommend them to anyone needing major plumbing work.
