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

"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"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."

"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."

"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."

"I canâ t say enough great things about Minuteman Water Heaters! I had extended family in town when my water heater blew on a Saturday. They responded quickly and professionally. For a weekend emergency they were also very reasonably priced. The entire process was so smooth. I would recommend them to anyone. Many thanks again!"

"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."

"Finally a great company you can rely on to get the job done! I have used them for my multi-family home for years and have always been so happy to have this wonderful team of people to help me out. From Joanie in the office to all the great plumbers, Brandon, TJ, Kyle, Jorge to name a few they are all so professional, friendly and knowledgeable. They are easy to work with, they call you 1/2 hour prior to arrival, cover their boots when they are in your home and have a low monthly charge for their service plan, which is worth every penny. Brandon has been out the most and he is a wealth of knowledge. He had so many issues to figure out this go around and he found all the issues in a methodical way. He's straight up trustworthy too. One leak was from the tenants toilet and needed a new flange and was pulled and set, and an old cast iron pipe cut and replaced with new pvc drain line. Another leak was from an old laundry valve which left a lot of water in the basement who knew?! An old shower valve was causing the rattle and was replaced. Lastly the for the other toilet problem, he suggested I buy a toilet and he would install it saving me hundreds of dollars! He even gave me the brands that he liked for toilets. Brandon even checked my furnace, gave me some suggestions and gave me a quote on the water heaters that are close to replacement. It was like having a family member checking to make sure everything was okay in the house! Thank you to Boston Standard for all the hard work!"
