My first encounter with Peter was for a leak in the bathroom sink. While he was there, he recommended replacing the main water shutoff valve which was showing the beginning signs of leaking. He has been back and done that work as well as some other plumbing jobs including another emergency call. He has been courteous and very professional - everything left in pristine order when he leaves. I would not hesitate to recommend him to others and to use him again for even larger projects.
