Black Mountain Plumbing, Inc. is on the short list of companies that I would recommend to other people. I have used them extensively, and I have been very happy with them! Most recently, they addressed a blockage problem in my drain line going out to the street. They provided the various options available to me, and eventually I will have to have the roots cut back. They are very knowledgeable, efficient people, and their prices are competitive. They do a great job for me!
