"Mr. Floros worked with my schedule on a short timeline to replace our water heater. He professionally negotiated with me about how to get the job done approximately the way that I wanted while still meeting local code. When the job was completed, he cleaned up and took away the old unit. The price was a great value considering the work done."

"Fantastic. Jeff is a pro. Installation went as described in both locations. He came back Immediately when I had a water gauge issue for my water meter ( installed 7 years ago) and replaced it on the spot. Jeff is professional, punctual, cleans up, old furnace removal and does great work. I’m very happy with my 2 new efficient heaters and hot water heaters! My heating costs are down substantially! I’m glad we chose Jeff."

"Justin and Cam, the technicians, did a great job. We have an old farmhouse with a very strange configuration of partial crawlspace and partial full basement, and water was leaking through the fieldstone foundation wall from the crawlspace. They quickly diagnosed that the problem was coming from 1 or 2 zones of the hot water radiator heating system, and they were able to shut off those zones to stop the leak, while allowing the house to still use water for sinks, toilets, and showers. We'll have to do more work later to replace pipes to the radiator but, because they are hard to access, we need to plan ahead for some construction work. I'm fully satisfied that these guys were able to find the problem and give us even a temporary solution that allows us to have our working plumbing again without the basement getting wet. Would definitely work with them again."

"I have had Spencer Home Services work on my house before and they were recently here again on an unrelated issue. Rich came out and solved the problem like any good plumber would. The difference is Rich’s attitude, respectful of our needs and time was outstanding. As a homeowner it’s great to know you can trust your repairman to do a good job."

"I had an incredible experience. My water heater was leaking and ready to let go. Brian had contacted me. He set up an appointment the next morning. The two gentleman ( plumbers ) came in. Removed the old water heater. Installed the New water heater. And updated the vent piping because it was old and out of code. They did a wonderful job. And I cannot speak highly enough of them , the speedy work and their professionalism. I now have a new plumber for all my plumbing needs. Thank you."

"Milltown was exceptionally responsive (before, during and after) the work was performed. Across the Milltown organization, they were responsive to my questions about water heater selection; Mike was responsive and a partner in selecting the best location for the new unit and after, Milltown and Mike were immediately responsive when part of the unit was not operating as expected. Milltown is a solid organization that takes pride in their work."

FAQs for water heater repair or service projects in Wilmington, MA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
