Serving Denver and beyond Sewer Repair Company Denver

I would hire this company 100% again Feb 20, 2026

Jon came out to check a sewer leak and was great with explaining everything in detail (I’m out of state) and giving me all the details as well as numerous choices on how to correct the problem. I would hire this company 100% again due to him!

Friendly, Thorough Service Feb 1, 2026

Friendly, thorough. Cleaned out a block in the main plumbing line (tree roots 😬). Coming back to scope, etc.

Zach Was Awesome Jan 28, 2025

Zach was awesome. Our laundry and furnace rooms flooded due to blockage in our main sewer line. I called no less than 11 companies that advertised 24x7 emergency service. None of them actually has 24x7. Quality First was the only company that called me back and sent a tech. Zach was incredibly friendly, professional, courteous, and thorough. Give that guy a raise. :o)

His confidence and knowledge were tremendous Oct 11, 2024

I had a home inspector out for the house I was under contract to buy, and he discovered a sewer in severe disrepair. I called Quality First to come out and quote replacement of the sewer, and Thomas was who they sent. He checked over the report from the home inspector, reviewed his notes, and did a diagnosis all his own which led him to a proposal for replacement. I knew this would be a massive project, but Thomas explained exactly how he and his team would take on the project and assured me it was something they could handle without issue. His confidence and knowledge and reassurance were tremendous, and I’m so glad I called Quality First and got to do business with Thomas!

I knew who to call Sep 13, 2024

I woke up this morning to a backed-up main sewer line. Having had Quality First out to our house in the country in the past for 2 different jobs, I knew who to call. They were able to get me on their schedule and had Josh G show up 3 hours later. He was very professional and extremely thorough given that we're on a septic system. I will continue to call Quality First for all my plumbing needs.

Friendly and Customer-First Attitude May 5, 2024

Carson came out to help us with sewage backing up in our basement. I really appreciate him coming out on short notice for a late night call. He was able to get the water draining again. Although there were some struggles and unexpected issues on his part, he maintained a very friendly and customer-first attitude. Update 5/4: Sewage started backing up in our basement again. We contacted Quality First and they sent out Brandon to try and resolve the issue under warranty. Unfortunately, the issue wasn’t with our own plumbing but with the shared main sewer line for the building. Brandon called in Chris to help diagnose the issue and found the clog over 200 ft away from our basement drains. Together they made a very great team, were very transparent throughout the entire process, were very friendly, had excellent customer service, and expressed genuine concern for their customer. Overall, we’ll definitely reach out to them and this company for any future issues and maintenance.

Sewer Inspection Service Included Jun 8, 2023

I had a sewer inspection service that was included when I bought a new furnace last year, so there was no charge. The tech, whose name is Brad, did a quick look in the line to the main and it checked out good.

They were very knowledgeable and personable Dec 6, 2022

Marcos, Phil, and Carson came to descale my sewer line and do other plumbing repair. They arrived on time and took care to protect the area around their work. They were very knowledgeable and personable. They finished the job quickly. I would re-use this company.

Great service and honest assessment Dec 6, 2022

Was referred to Quality First by our neighbor who has used them for a while. Had some plumbing backup issues in our basement mechanical room. They were able to respond same day and provided great service and an honest assessment of the main line to the sewer as well as options for both short and long-term. Carson W. was our technician and is a very polite and professional young man. I will be requesting him for any future services that are part of our annual membership. J Farr

Fantastic service pros Jun 30, 2022

Zach Duran and Chris Rivera are fantastic service pros - they are effective, efficient, friendly, skilled, and professional. Due to a “belly” discovered in the mainline of the building, techs are sent out to keep everything in tip-top shape - I trust these guys implicitly.

They Were Both Very Helpful Jun 29, 2022

Had the pleasure of meeting Thomas and Chris today to get a second opinion on sewer line work. First, I must say they did a great job acknowledging our pets and were respectful with our dog training (this stuff matters for animal lovers like us!). As far as professionalism, Thomas and Chris were both easy to talk with, explained the steps well, and were able to answer questions I had. They were both very helpful, and I appreciated their time today.

They were very honest Feb 26, 2022

Thomas and Phil replaced our sewer line. They explained everything and really helped us through the entire process. I plan to keep using them, as they were very honest.

Excellent service from your technician Feb 25, 2022

Excellent service from your technician, Zach Duran. He got to our home sooner than expected and handled our sewer backup quickly and efficiently. He even cleaned up afterward. Thanks
