Recommended Customer Reviews

Best plumbers! They are always professional and fast. They are my favorite vendor! Reliable, honest and trustworthy! I am a property manager, and they are the plumbers for all of my commercial properties! I highly recommend them!

Great customer service. Lizzie in the office was able to get service for my client right away. The guys are super professional. Will definitely use again!

Sierra came out and repaired a leaky pipe in my kitchen. They did a great job and I haven't seen any leaking since. I'm happy with the service and would call them again.

I am a property manager and am responsible for the oversight of 5 commercial multi-tenant buildings and 1 residential property. Sierra plumbing has met all of our plumbing needs with no issues. Their staff all the way from
dispatch to management gage been responsive and very professional. The technicians have been communicative and thorough. They are reasonably priced and go the extra mile to ensure that I am happy as a customer. They have been a breath of fresh air to deal with; especially with the way the industry has drastically changed since COVID. I truly believe you will be happy with their services if you choose to try them.

Contacted these guys about installing a septic system, and they gave the HIGHEST bid which was downright offensive. My average bids to do the job were $45k to $50K. Sierra came in at $102K.
When I called them on it, the owner began claiming the ""costs"" for materials were over $45K, and then insinuated I ""probably have never done this before.""
Well, I have. And I had done my homework, and I know what this stuff should cost.
It is my opinion, I believe they did what many contractors do. When they saw a custom home in a nice neighborhood, they just jacked the price up as high as they thought they could.
I would not recommend this company based on the bid I got.

Top notch company from large projects to small they are my go to plumbers. Quality work they stand behind.
