5.0 Chuck W. Mooresville, NC

When our Water Heater went down during the coldest time of the year, I used Angi to request an estimate. John from Water Heater Experts was the first to call and, though I had not considered it in the past, sold me on the idea of the tankless system. He had an answer for all my questions regarding finance and made it easy to afford this upgrade. He showed up late due to prior service calls, but he was committed to getting it installed and working before he left. Thank you, John and Water Heater Experts......Looks GREAT, Works GREAT!

5.0 Stephen B. Weddington, NC

John Gallagher did an outstanding job installing my Rinnai tankless water heater. He spent a lot of time educating me on tankless water heaters. I got six different quotes and he was the most reasonable and the most knowledgeable of those I spoke with. I would highly recommend him to anyone having a plumbing need, especially a tankless water heater installation. I was so impressed with him that I'm having him come back to fix two things that previous plumbers did incorrectly.

5.0 T P. Charlotte, NC

We noticed our water heater had a leak in the morning. We decided to replace it and started a search early afternoon of the same day. Fortunately, we came across with John who came to our house by the evening. He took out the old unit and installed the new one and finished most of the installation on the same day. He came back the next day to finish the job. He also contacted us the next day to follow up the next day The cost below is net of tax credit and other incentives. We are quite happy we found him.

5.0 Kate C. Cornelius, Nc, NC

John was responsive to my outreach, offered a variety of options, and completed the job within 48 hours. He completed quality work that passed the first inspection, and job was at a reasonable price.

0.50 Colby A. Charlotte, NC

This company shows a lack of follow through and has poor communication.

5.0 Steve C. Denver, NC

John, came on a Sunday and worked late into the night to get our tankless water heater installed and operational. Fair pricing, subject matter expert on the systems, dedicated to good work and generally pleasant experience working with John and his company. Highly recommend.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
