"I had a water softener and filtration system installed in my home. It's fabulous! Austin was very reliable and friendly. He was extremely efficient. I'm so happy with my system, and with Jones Air and Water."

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"Mayo Plumbing is different from all the rest. They use data and research to inform their work. Before calling Mayo I had two different plumbers look at our new (very old) house. The first said, "St. Louis has hard water - you NEED a water softener." The second said, "St. Louis has great water - you DO NOT need a water softener." Mayo said, "What did the test results say? No one can tell you you need a water softener without testing your water first." BINGO. They tested our water and determined we DO NOT need a water softener. Same approach for our broken shower. The mayo plumber actually researched the issue, spending time with the paperwork and on the phone with the Kohler rep to determine exactly what we need to do, before making a wild guess and upselling us. I've never seen a plumber like this - these guys are SMART and will be our go-to provider!"

"I was impressed from the moment the owner introduced himself and his assistant to the time they left my home dirt and soot free. Not only did they do a fine job cleaning he also checked the dryer vent. Will call them again next year.

"Sam replaced a water heater that was under an enclosed counter area after removing the old water heater, and replaced a damaged circuit breaker for what seemed to be a very reasonable price. Many difficulties arose that were not anticipated and he handled them all in an extremely professional manner. Definitely someone to keep on my contact list."

"Did a fine job installing water heater, but then the installer apparently did not push out the air in the lines through the house. The faucet in the kitchen then loss water pressure since there was debris from the old water heater in the lines. I was told there would be no charge when they came back to investigate for the inspection fee, but there was. I made my case and then it went away. Overall, they did a great job with the work. Ted and Glen are the ones I would want back. Very experienced at the trade."
