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

"Jordan and his crew responded quickly and discussed various options. We decided to replace the old conventional water heater with a modern tankless system. I could not be more happy with the same day service, honesty, craftsmanship and professionalism of the team. Thanks for the reference."

"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."

"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."

"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing 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."

"Chris from CMK Plumbing and Heating is very professional. His work is clean and neat. The quality of his work is excellent. He is very responsive and his pricing is fair. I would definitely call on him again and would gladly recommend his company."

"Had oil heat system replaced to tankless, after converting to gas. Job was done perfectly, finally have unlimited hot water supply, and we have since used blue bear for other small plumbing jobs as they come up."

"My water heater died (leaked) late Wednesday nite. Thursday I called numerous plumbers-left messages, Burke's called back and by Friday afternoon I had a new water heater installed. I am in a mobile home and some plumbers said they don't service mobile homes."
