We have used Black Mountain for decades! Water heater went out on a Thursday night, and they arrived early on Friday morning with a replacement. I appreciated the options given by the office staff, and chose to replace the 13 year old unit. Everything was explained as the replacement was being accomplished. The garage was left neat and tidy and the job was done in about 4 hours. I would recommend Black Mountain, and have, to anyone needing a plumbing company,
