Definitely Will Call Allen Service Again
Service on Sunday to repair a hose bib. The technician, David, did an excellent job explaining the work needed, and he identified a couple of other minor plumbing repairs that could be quickly handled. He was very knowledgeable and did an excellent job explaining each of the repairs. He executed the work efficiently and, based on my post-repair review, the workmanship was also excellent. Definitely will call Allen Service for any future plumbing work.

Brian Deters
Happy to Have a Functioning Kitchen Sink
Arrived on time and was very polite! He was upfront about what needed to be done and gave me several options to choose from to have either a long-term fix or short-term cheaper fix. We had some janky plumbing under our kitchen sink, so I opted for the better fix. This way, if it clogs, it will be much easier to access. Happy to have a functioning kitchen sink! You don’t realize how much you use/need it until you can’t use it!
Heather Cramer

Antoine Garcia

Joshua Datko
Excellent, Thorough Same-Day Service
Allen was able to get us a same-day appointment according to a window that worked for our schedule. Mason, our technician, was timely and did an excellent job—he was very thorough in his assessment and explanation of his findings, reviewed a range of options for addressing the plumbing issue, and went above and beyond to fix things for us that day. No pressure to invest in unnecessary or expensive treatments but offered a range of choices. He was very pleasant and easy to work with, respectful of our home and time, and even great with our dog. Will plan to work with Allen Service, and hopefully Mason in particular, anytime we have a plumbing issue in the future!
Michael Brinker
He Was Outstanding
We recently had the pleasure of working with Matthew Mish for our plumbing needs, and he was outstanding. From start to finish, he was courteous, honest, and highly professional. He arranged everything efficiently and made sure the job was done right. It's not always easy to find someone you can trust, but Matthew exceeded our expectations. He’s definitely someone we will ask for with any of our future plumbing needs. Highly recommended!
Jeffrey Lund
He Went Above and Beyond
My technician Carson was so prompt and helpful. I think the company in general was really responsive, which I appreciated, but he went above and beyond. He worked through my broken sink issue and was informative along the way. He was extremely polite and efficient. I would absolutely ask for him again!
Dorothy Green
Had a great experience with Lance
I am a professional landlord and own many houses in Denver and Aurora. Had a great experience with Lance at Aurora Plumbing today. Arrived on time and same-day service. The company probably charges a little much, but they were there and did the job for me.
Scott Lukes
Aurora Plumbing/Quality First Plumbing is great.
Aurora Plumbing/Quality First Plumbing is great. They show up on time, they communicate clearly and their pricing is fair. Lance McCartney has worked at my home twice and both times I have been impressed. He is efficient with his time, he is polite and friendly and kindly answers all questions.
Jacque Campbell
Chris was awesome
Chris was awesome. Worked like a dog all day and took care of our problem, and he was professional and thorough! Ask for Chris if you have plumbing problems!
Marianne Melton
Very knowledgeable and thorough
Gavin is very knowledgeable. He went through all the questions I had with my plumbing, checked everything out, and gave me a detailed estimate of everything I requested. I had him replace the hot/cold faucets on my washer, and he did a great job. He recommended several things which I will follow. He even paid attention to my cat, CJ. I would definitely recommend Gavin for any home plumbing concerns.
Sheryl Pitts
Great Service
Great service. Zachary was very professional and fixed my problem with my plumbing in a timely manner. Very satisfied.
Katherine Gorski
I Will Continue to Use This Company
This has been the first time I’ve used this plumbing service. Rick was here today for the 2nd time in two weeks. He is patient and kind, very friendly and respectful, and he answered all of my many questions. He worked hard to get me a good discount for the new work since the original work did not completely solve the issue. As a result, I will request him and continue to use this plumbing company in the future.
Karen Knudsen

Clint Schaeffer
Josh was great!
Josh was great! Kept us informed and took care of a complicated plumbing issue. Very thorough and complete.
Dale Crawford
Kind, Courteous, and Truthful
Lance and his assistant were kind, courteous, and gave me a truthful assessment. Unfortunately, the bid was well above what I was ready to pay. They called their manager, but it was still too high. My sense of Lance is that he's a good plumber.
K Hansen
Their Technician, Zach Duran, Was Fantastic!
We had a plumbing issue and Quality First was at our doorstep within 24 hours. Their technician, Zach Duran, was FANTASTIC! He was informative, kind, and helpful! He proceeded to solve the problem within minutes of his arrival. I highly recommend!!!

Had an amazing experience with Dan
Had an amazing experience with Dan. He was extremely knowledgeable, professional, and friendly. He took great care of us after needing a valve replaced.

Real nice and explained everything. I do miss Aurora Plumbing. I'm sorry you merged.
George VanSlyke
Very professional and clear
Zach was very professional and explained everything clearly and had great preventative tips. He’s a go-to for any plumbing problems.
Bob Wakefield
Richard D. Was Excellent
Richard D. was excellent. He walked through everything with me and explained what he was checking and why. He also walked through the portion of the estimate with me and what they were for and what was included. The survey didn't have his name on there, so I'm not sure why the survey portal isn't up to date with all technicians.
I can provide his full last name to staff at Quality 1st Plumbing to ensure he receives his recognition.
