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

"I recently had a tankless water heater installed by G&C, and I couldn’t be more impressed! From start to finish, they were professional, kind, and incredibly efficient. The team arrived on time, explained everything clearly, and worked with precision and care. They left my home spotless and made sure everything was running perfectly before they left. It’s rare these days to find a company that combines expert craftsmanship with genuine customer service, but they truly deliver both. I would highly recommend them to anyone looking for reliable and trustworthy plumbers. I’ll definitely be calling them again for any future plumbing needs!"

"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"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."

"Outstanding. From the original estimate of services to be performed by Eric A to the install work, which was NOT an easy job, performed by Gil, Luis & Chris it was excellent job well done! Gil kept in contact with me throughout the job and provided his cell phone in case I had any other questions. As a small business owner I pay attention to details and know how important customer service is and this team from Cotti-Johnson were top notch. I cannot recommend them highly enough."

"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."
