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

"He called us early morning and by early afternoon we had a new hot water heater. Very professional. I would recommend to all."

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

"Chris Keith and his workforce did a great job of installing my tankless forced hot water heater. The job was completed on time and on budget!"

"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."

"I had a great experience with Wicked Plumbing. They came to my house on time, and replaced my broken water heater with a new one."

"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."

"Fixed leaking water connection to dishwasher and installed a 2 stage sediment filter. Highly responsive to our requests and good communication before, during, and after the repair. We will be using them again."

"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."

"In April 2026, our broken cast iron pipe needed to be replaced, but we didn’t know how extensive the repair would be. From Angi's referrals, we called Full Swing Plumbing who arranged for Nick, one of their plumbers, to come to our house that same afternoon. Full Swing waived the dispatch fee. Nick used his endoscope camera to see the extent of the problem. (They had a coupon on their site which offered this one-time, free service.) After a couple hours, they were able to identify the problem, present a few solutions, as well as a final estimate before they left that day. We agreed on the approach and set a date for the following week. Nick and his co-worker were friendly, deeply knowledgeable, and hard-working. They communicated well, taking photos for us throughout the process. They cleaned up everywhere, completed the job in one day, and they kept to their price. Everything worked well from the single visit."
