Get matched with top tankless water heater installers in Cohasset, MA

"We have had several Sila visits in recent months - all exceptional. VISIT 1: We had old pipes and valves that limited our dishwasher, so we had that replaced. While there, the Sila agent suggested we replace some of the attached lines and managed to streamline our hookups by removing some of the unneeded valves and connections no longer needed. VISIT 2: We similarly had a great visit and instal from David, who did a very beautiful install on our new water heater. He removed the broken unit, improved the connection design, put in improved valves and labelled each with a tag, then tagged other connections through the basement."

"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."

"Amazing experience all around. Easy to schedule and to work with, good deal and amazing work installing a tankless water heater. I will definitely call for any future needs."

"Great sales rep and installation team. Easy to work with and up front with their price and work."

"I called Ryan for my water heater leaking. He came within the same day, ready to go and replaced it quickly. He provided a great service and affordable price. Highly recommend him for any plumbing needs."

"I am a new homeowner that was looking to complete a few projects around my new home but wasn't sure where to get started. I recently had a heat pump installed and integrated to my existing oil furnace by Blue Bear. The Blue Bear project manager helped explained the difference between fully electric heat pump systems and dual fuel heat pump systems, both options were Mass Save eligible so I would be able to benefit from an instant rebates and not have the hassle of filing rebate applications! Blue Bear took care of it all! We chose a dual fuel heat pump system and the installation looks great! I look forward to saving on oil consumption this fall/winter! Everything went well with our HVAC install and now Blue Bear will be installing a whole home well water water filtration system in my home! We look forward to getting rid of the water staining in our toilets and showers! The Blue Care maintenance plan was a no brainer to sign up for! I highly recommend Blue Bear! 5 out of 5!"

"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!"
