Beware of 3 Mountains Plumbing. They'll take advantage of your lack of knowledge and your trust. I ended up paying $5,479.00 for a job that was t necessary, that was grossly overpriced, and that they failed to complete. This is in addition to the $2,174 job that I paid them to replace a pipe they ruptured when they snaked it. On July 20th, 2023, I hired 3 Mountains Plumbing to check for a possible obstruction in the sink of the basement. They suggested snaking it. When they did this, they broke the pipe and blamed it on the fact that it was an old, galvanized pipe. I will never know if the pipe broke because it was old or because the twenty-something employee who snaked it did not know how to properly operate the snaking tool. They charged us $2,174.50 to repair it. In the process, they scoped the underground pip, determined that it was channeling, and strongly advised us to replace it. In their estimate, they calculated that they would have to dig a 20-foot concrete trench using a jackhammer. They also said that it would take them â most of the day to complete the first phase of the job, which consisted in finishing the installation for approval by the city inspector. Their estimate for this second project was $5,479.00. Since the underground pipe was not leaking and, according to the plumber, it would take one or two years for it to leak and cause any damage, it was not an urgent problem needing immediate attention. Nonetheless, my partner and I decided to heed the plumbers strong advice to complete this project. Our only condition was that they finished the job by August 10th. We clearly expressed to them that, unless they could commit themselves to completing it by this date, we would not approve the project. They accepted this condition and deadline and completed the first phase of the job on August 1st. It took them a little more than two hours to complete it (rather than most of the day) and the trench they dug was less than 6 feet long (rather than 20). Not only did they grossly overestimate the time and effort it would take them to complete the job but, on top of it, they failed to complete the job by August 10th. They refused to adjust the inflated estimate when I pointed out this large discrepancy between their estimate and the job they actually did. I ended up hiring a different company to finish the job 3 Mountains Plumbing failed to complete on time. The plumber who finished the project commented that it was poorly done and unnecessary because the old underground pipe they urged me to replace was still in good shape. So I ended up paying $5,479.00 for a job that was not necessary, that was grossly overpriced, and that they failed to finish on time. This is in addition to the $2,174 job that I paid for the old pipe they ruptured when they snaked it. As a result of their negligence and abuse, I decided to file a complaint with the Oregon Department of Justice.

Arrived and fixed same day. Good price.

5.0 Irving P. Portland, OR

Nicholas was excellent! Great communicator, accommodating and did great work. I really appreciate how they charge by the job not the hour. I would recommend their hydro jetting option.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
