I have used Black Mtn Plumbing for years, on many tasks big and small (replacing my water heater, reseating toilets, installing garbage disposals, even small valves - you name it!) They always show up on time and do the job right. They clean up and keep me informed. They think through everything for me. Their guys are friendly and helpful, patiently answering all my questions. I value how careful they are with their work, they take the time to do things right.
