Get matched with top tankless water heater repair pros in Hingham, MA

"Jordan and his crew responded quickly and discussed various options. We decided to replace the old conventional water heater with a modern tankless system. I could not be more happy with the same day service, honesty, craftsmanship and professionalism of the team. Thanks for the reference."

"This was a relatively small water heater repair, and Ryan did an outstanding job. He responded immediately to my request, provided a reasonable quote, was polite, professional, knowledgable, and friendly to deal with. Will definitely hire again if needed."

"Guy did a great job of diagnosing and repairing our State Hybrid Electric water heater. I would definitely recommend his work."

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"Came out the same day and did the repair efficiently and professionally. Technician was very knowledgeable and friendly. No complaints."

"The technician arrived later than expected but he explained that there was an emergency that morning and was courteous once he arrived. The tankless water heater was making intermittent noises and a descaling was done. I haven’t heard noises since so hopefully the water heater will last for many more years. The technician said typically lifespan is only 7-10 years which is shorter than the 20 year I have in mind."

"Same day installation. Called at 10am, 20 year old hot water heater replaced by 3:30 pm."

"Outstanding customer service from start to finish. The plumber was knowledgeable, respectful, and left everything clean after the repair."
