He was absolutely on time, friendly, knowledgeable. He went way beyond the call when we discovered that the placement of the drain pipe would interfere with the new vanity installation. His efficient solution was to re-route the pipe through the wall and around a corner...complex, but beautifully executed. He also had a huge variety of standard and non-standard parts right on his truck, eliminating the time (and cost) of a trip to the plumbing supply house. I would recommend Dave Miller to anyone without any reservations!
