Chad Knowles did an outstanding job working on our plumbing issues. Our water pressure was way too high due to problems with the pipes and valves near it. We also had him install a garbage disposal, fix some leaking faucets that had been leaking for a very long time. While installing the garbage disposal he noticed…
Amazing experience with Heil. Water pouring out of the side of the house by the outdoor spigot at 7pm meant we had to turn the water off in the whole house. Scheduled online for a 7:30-3 window the following day. We called first thing asking if we could narrow the window so we could make arrangements with work, and…
Jake was thorough and he accomplished all our goals. He was polite and easy to have in the house. I would be pleased to have him return to do more work when it is needed. Both times I have called Heil you have given me prompt, expert service.
Friendly service.
The service was efficient, and I was kept informed the entire time. I would recommend Heil to my neighbors

We call Heil for all our plumbing needs — and there have been a LOT in our new old home. Jake is always meticulous, reliable, knowledgeable, professional, courteous and friendly. We request him every time. Thanks for being a service provider we can trust our house to!
Eric B was fantastic. He came to fix our kitchen and down at least 30 mon on the phone with Delta, and they gave g him the complete run around! He figured out it was defective. He gave us guidance on purchasing a new one (we went with Moem this time—we’ve always had good luck with their products). I called Heil this…
Heil Plumbing has wonderful customer service and fast professional services. We needed a total replacement of the water line to our house. It was a complicated job on an older home. Work was done with minimum digging. The new work is more accessible and should last a very long time. Highly recommend this company.
Happy with the service. Easy scheduling, nice people. When the specialists came, I knew I was in good hands. Knowledgeable and professional.
Eddie was great! He not only solved our issue quickly he pointed out arenas of concern.
Friendly and efficient. Honest with initial quote compared to what was actually needed saving me money. Completed entire job in a very timely manner.
Quality service, friendly and honest, and decent prices.
Eddie was fantastic and professional. He was able to fix the issue in no time
Clean, professional, friendly. Couldn’t have asked for better service.
We had a serious leak where the ceiling collapsed. We called Heil Plumbing in a panic. They sent Jeffrey out. He arrived and took care of the problem all the while informing us what he was doing and why. The problem was identified and fixed quickly. We are so appreciative. Thank you Jeffrey. Heil Plumbing will be the ones to call moving forward.
He was through and fast! Great to work with
Excellent job!!!!!! Very professional and remarkable service!!!!!!! Highly recommended to anyone and family!!!!!
I was smelling gas under my stove and my water heater was not working. Israel answered my call and helped get a technician out right away all while being polite and professional. Jeffrey showed up first thing in the morning of the scheduled service day with a smile and eagerness to fix the issues. He took the time…
Jeffrey Thomas came to our house and provided excellent service and information. I couldn’t be happier about my experience with Heil Plumbing.
Jeff Thomas is awesome. He did a fantastic job installing a pressure relief valve for my house that will prevent future pinhole leaks and other damage to my pipes. Hands down one of the best plumbers I’ve come across. He always solves the problem timely and in a way that makes sense (to me, a non-plumber), and…
Very comfortable recommending Heil. Good service, professional and polite plumber, fixed everything quickly, explained everything that he was doing, and charged a reasonable amount of money. Will use again for plumbing emergencies
Seth was a great professional with a friendly demeanor and patient attitude, knew his trade well and got the job accomplished to our satisfaction. Happy that I went with Heil Plumbing
Jeff Thomas was professional, smart, only charged for reasonable costs, and cleaned up afterwards. We will use Jeff Thomas again for plumbing work.
Extremely professional and very prompt service. Others in my neighborhood use these guys. I will absolutely call them if I have further needs
Eddie Heil and Heil Plumbing are incredible! I have used Heil plumbing for over 10 years on multiple jobs and they are responsive, experts at what they do, and always professional. I give Heil Plumbing my highest recommendation!
He did good on finding leaks in water pipes.
Punctual, even for an early call. Professional, courteous, & fast in completion of the service rendered. Explained every pros & cons then delivered. HIGHLY RECOMMEND! BTW, Eddie was awesome! UPDATE: 3/31/25 Seth did an awesome job of providing a ‘peace of mind’ repair to a corrosion serious leak. I may move forward…
Tech arrived on time, gave clear feedback and pricing was pretty good. Overall very pleased with service.
If you need any plumbing work, use this company! They called me back right away, answered my questions and got me someone to my house quickly. The plumber, Ken G was amazing. He had a great attitude and I felt very comfortable having him in my home. He immediately got to work and found the problem and fixed it for a…
Can’t say enough good things about Joe Welch, he was awesome! Great work!!
Eric did a fantastic job helping identify the source of the leak quickly and was very knowledgeable. The leak was not plumbing-related, and he was very forthcoming with his information. I will absolutely call again for future issues.
Eric was outstanding, getting my plumbing issues taken care of in a professional quick manner
Eric did an amazing job figuring out where water condensation was coming from as well as getting the fire suppression re-certification done! Super happy with the work and WILL be calling Heil back for any future issues! Thank you!
Came on time, assessed the job fairly, and completed the work efficiently and well. Thank you to Nick and Chase from Heil.
