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

"Discovered our 6 yo gas water heater developed a leak. Decided to call on these guys as they provide the annual maintenance for our A/C and furnace. Called early AM and they were able to have a service technician on-site within 3 hours. After inspecting the tank and finding the source, the technician proposed the replacement options. Although most seem costly, the technician did a great job of explaining the work involved and how much time it would take. After doing some research, I went with these guys....and everything went to plan. Was able to schedule an appointment that worked for our schedule. The same technician came back out with another colleague. The entire job took about 5 hours. They answered all my questions. And they worked very neat. Yeah, they weren't the 'cheapest.' But, they corrected some previous issues, worked efficiently and completed the job correctly and in relatively quick time. They new exactly what to do and how to do it. Very good experience. Thanks, SILA team!"

"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!"

"I spoke to Lou Schede about a horrible sound coming from my washing machine when the hot water was on. I'd already had an appliance repair man in, who suggested that I contact a plumber. I was on and off the phone with Lou all day, sending pics of the valves etc and communicating with the super in my building. Eventually it was determined that the issue was not with the plumbing overall, but was limited to a faulty valve. I believe I have found in Lou Schede a true master in the service industry. Someone who is willing to put the time in to figure out the source of a problem, without any sort of upfront payment. Because of Lou's integrity and the level of verbal service provided, as well as his willingness to speak with me patiently and clearly, this will be my first call in the future when I am ready to do the inevitable renovation of this condo."
