Get matched with top tankless water heater repair pros in Stamford, CT

"It went very well! Doug was on time, friendly and professional. He found a problem which we will have repaired soon."

"When we realized our water heater was leaking, Aldo's was fast both to respond to the inquiry and to get us a replacement; within 36 hours, we were back to having hot water with a new tankless setup. Pricing was within the range we expected and the team was very communicative; I'd hire Aldo's plumbing again!"

"Professional, courteous, responsive, and fair price. I highly recommend and will use them again. E and R Plumbing was 1 of 3 companies recommended to me by HomeAdvisor and I contacted them because they had the best reviews. Almost immediately, I received a call from Rich and while he was on the phone, he asked me to send over pictures of my 16 year old Water Heater Tank that needed to be replaced. He quoted me a fair price for both a Tank and Tankless water heater and I decided to go Tankless. Rich and two colleagues showed up the next morning, removed the old Water Heater Tank and built out a plywood mount to install a new tankless water heater directly behind where the old tank was, taking up less space. Rich and his colleagues completed the job exactly as described, and Rich called later that afternoon to make sure everything was running great!"

"Matt was great. Very responsive, professional and efficient. Installed a new hot water heater for us is no time. And a very fair price!"

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"Oct. 6 2025 it went quick. I received an estimate of The job first. The work was done correctly. It didn't take long. If I need plumbing service again. I would contact Cassidy plumbing & Heating."

"Tom was terrific....repaired boiler....cost reasonable.....explained everything so clearly so that even this 88year old understood it....experience with company from start to finish was a pleasure"

"Lou and his technicians were great. They provided timely, accurate quotes and explained everything about improving our hot water service and all of our options. The technicians came on time for all appointments and were incredibly helpful. They explained everything to my wife and I, and were very helpful. We would hire them again for any plumbing needs."
