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

"What a great experience! I needed a water heater replaced ASAP, and Mike and his team replaced the heater quickly, with no issues, and at less than half the price of the next lowest bid. I'd highly recommend Mike's Plumbing."

"Company responded fast to an emergency. My heat pump/hvac unit failed in 90deg temperatures. Technician came and diagnosed that system is 20 years old and needed replacement. Sales team was excellent and helped pick the right system for my budget. New system was in stain less than a week. Will hire this company again"

"We decided not to go tankless but E&R did a great job installing a new 50 gal Rheem heater. Very quick and clean install. I will use them again in the future."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"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."

"The firm responded immediately to my inquiry and arrived at the scheduled appointment date, assessed the necessary repair, went to the closest plumbing supply house and obtained the necessary materials and returned promptly that day to make the corrections. The crew was courteous and professional."

"Installation of tankless water heater was completed in a very efficient manner. Service was priced fairly and the owner Augie was personally involved from start to finish.

"I cannot recommend Mark more! We called him for a dishwasher installation and pipe repair. He quoted us reasonably - and was generous with his work and time when what we thought was a simple job turned out to be much more complicated. He was absolutely a pleasure to work with - communicative about the issue and his solution, flexible with scheduling, and just an all-around nice guy. We will not be hesitating to call him in the future - our go-to-guy for all plumbing needs."

"Repairman, Andrew, came and located the problem. The ignitor had burned out, so the burners would not light. Andrew did not have the part in his truck but was able to fit in a used part from another furnace to give me heat until he got the other part. I got a call the next day and scheduled a time to put in the exact part. Again, repairman was within the stated time window. Heat working well."
