  • Thomas was a great help in getting our water back to our apartment. He was very professional, informative, and solved the issue of our broken water heater. I would highly recommend Quality First for any plumbing needs!

    Ethan Martinez
  • I really appreciate when I get the call prior to arrival time with service appointments. I’ve found it doesn’t always happen, but Q1SG said they would call prior, and they did. Thanks to Thomas for his knowledge and presentation of options, also for getting things running again!

  • We called Quality First in the midst of an emergency, Sunday morning. Our water heater was failing (it appeared), leaking, and damaging our wood floors and subfloor. Even on a Sunday (without a prior appointment), Damon got us scheduled for a technician arrive that very same morning! That was the beginning of their great service.
    Tyler, our service technician, was fantastic! He immediately diagnosed the issue and confirmed our assessment that the water heater needed replaced. After a few hours we were all set up with a brand new unit. The unit itself is high quality and workmanship by Tyler is top notch. He (Tyler) was friendly, professional, courteous, and most importantly-very good at his craft. This isn't our first time using Quality First, and for good reason, it won't be our last!

  • Phil did a GREAT job. He was early for our appointment and explained the service that I needed. He got the parts he needed and replaced the water heater the same day.

    Thank you Phil

  • Brad, Carson, Emilio, Tony, Thomas and David did outstanding work replacing my HVAC unit and water heater installation along with fixing a leaky shower faucet in my condo. Answered all my questions, high integrity, did the job right, always making sure I was happy with the work. Quality First have become my "go to people" for plumbing or HVAC work. They really care! And take pride in what they do.

  • Ray did great work on a tough job replacing a network of lead pipes in my 98 year old house that were not up to code. There were a number of unexpected issues that he resolved without extra charges to me. I would highly recommend him to anyone in need of a solid plumber with many years of experience.

    Michael McNelis
  • Ray was fantastic! Found the source of the water leak, repaired it, etc! He was extremely professional, and explained everything in detail. I would highly recommend this company!

  • Thomas and David both excelled professionally and socially. They did a job well done and we are very pleased with their work. They completed the task efficiently and with great quality. Both were also very easy to converse with.

  • Thomas and David both did an amazing job fixing my leaking kitchen sink. Not only that but Thomas also did a great job explaining how to fix minor sink issues. I loved how easy they were to chat with and open to any questions we had.

  • Brad was so great! He was fast and polite and was even very sweet to my very nosy 4 year old

    Faith Schenck
  • When Thomas and Marcos arrived, right away I felt at ease. They were professional, courteous and confident. I had an idea I had a condensation issue but didn’t know if that was the leaking problem in my crawl space. Thomas and Marcos went into the crawl space and, within a couple of minutes, identified the condensation pump as the problem, found a hole in the pump’s hose as the leak origin and replaced the hose. All within about a half hour. I knew I wanted to Join the Club so, Thomas had already started the service by checking my sump pump and pipes in the crawl space. He found the sump pump was not running and was 3/4 full of water. He took care of that issue as well.

    I am so pleased not only with the excellent job they did, but also with the many recommendations Thomas gave me for preventive maintenance in my home. I really appreciate their professionalism and expertise. I’m glad to join the Quality First Service Club!

  • It is rare to obtain quality service these days. One may feel at a disadvantage the moment repair folks step through the door.

    One wants the job done right the first time with professionalism and honesty.

    Brad came to my home on 8/18/2022 and provided excellent service-clogged kitchen drain-professionalism, plumbing advice, and conversation.

    Thank your Brad, Quality First, for your service.

    Victor Cooper
  • Long time customer of Quality First Service Group and this last visit did not disappoint. Thomas and Carson were clean, professional, knowledgeable, and helpful. I’ll add compassionate to that list because not only did they leave things cleaner than they found them, but they also found and rescued a frog and released it outside. Overall, we couldn’t be happier with the install of our new hot water heater. Thanks

  • Phil and Chris came to our home to fix a plumbing problem. They were on time, friendly, and professional. They quickly fixed my problem and checked out the rest of our faucets, toilets, etc to make sure we wouldn't have problems with them. I've had Quality First come out for multiple issues and always received excellent service.

  • I got great service from the folks at Quality First Plumbing today. I found my hot water heater leaking earlier today and they got out to me and installed a new one on the same day. They were very courteous and professional. They cleaned up after themselves and did an excellent installation job. Thanks!

    Mike Rogers
  • To date, all of our experiences with Quality 1st has been top notch. From scheduling, to the work performed, they are their name. We feel fortunate to have found them.

    Heidi H.
  • I have recommended quite a few people to use Quality 1st Plumbing. Everyone I have recommended raves about them. The plumbers they send out are different from the plumbers you get from other companies. They are on time, professional, and the type of people you don't mind having in your home. I have used Quality 1st Plumbing for several larger installs, as well as some basic problems with a sprinkler system. They always do a great job. I have used Howie since he started the company, so 2 or 3 years now. The plumbing company I used before would fix something and then have to come out and fix it again. It was not a big deal, but Howie made the company Quality 1st so that people would understand that quality is the main selling point. If you want it done right, and done right the first time, call him. If something isn't done correctly the first time, Howie goes way beyond the call of duty to make it right. I have seen him fix things for free, even when the company was not at fault, just to make sure his customers are happy.

    Patrick J.
  • I rarely write reviews for companies unless they make a lasting impression and I must say that after years of plumbing service headaches, I'm happy to have found a company that provides all that's expected and more. The service call was professional from start to end and I really appreciate that estimates over the phone. More specifically, your technician Steve was one of the more professional service technicians that I have ever encountered. He was not only knowledgeable and very helpful, but I didn't feel like I was interacting with a used car salesman. He was very efficient, clean and respectful of my home. What a great first impression that will ensure I use Quality 1st again.

    Heather W.
  • I have known Howie for a few years now, and I have been using Quality 1st Plumbing pretty much since he started the company. He has always been a gentleman to speak with. He takes time to explain what needs done and how he can help. I feel like he is fair and responsive.
