“I had The Plumbing Doctor do a range of things over a few visits. This included major outflow pipe replacement, snaking of the main kitchen drain, replacement of a toilet, replacement of a shower fixture, and some other minor items. They did great work, provided good background info on what they were doing, and were very prompt—highly recommended.”
