Get matched with top water heater installers and replacers in Saint Charles, MO

"Did a great job replacing my water heater and was about 30% cheaper than the other bids I got."

"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"Remove electric water heater and install a new high efficiency gas water heater."

"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"Gave a bid at 8 AM and came back with a 40 Gal. water heater 2 hrs. later. Did the work and my renter had hot water in about 35 minutes. Good job. They have got my business. Thanks."

"Amazing experience from start to finish. Super responsive, professional, and easy to work with. The water heater installation was done quickly, cleanly, and exactly as promised. Fair pricing, great communication, and quality work — I’d absolutely hire them again."

"I have been dealing with a recalcitrant shower valve for some time (the manufacturer, Eljer, is no longer in business and the exact cartridge needed is hard to find) thus the main water shutoff valve had been used fairly often. Unfortunately, it broke in the "on" position and began to leak around 4:00 pm one afternoon. I looked up plumbers on "Nextdoor" and began to call. This was the first answer I received and was instructed on how to use the outdoor shutoff. The call ended when he offered to come by to help if I couldn't get it under control in 15 minutes, which I was able to do. He showed up as promised the next morning, quickly replaced the valve with a far superior one in minutes, and efficiently cleaned up the dust produced by having to saw through some drywall. In short, everything done as promised. A true professional, and a nice guy. Highly recommended."
