A water heater that broke on a Saturday got a phone call back within a half an hour — the homeowner who wrote that November 2024 review had not expected to hear anything until Monday, and says they were there Monday and everything was done expertly. Kevin M Cashman Plumbing & Heating works out of Tyngsboro. Two September 2024 reviews land on the same two things: the job was completed quickly, and the price was very fair. A December 2024 review describes a new install of a tankless combo gas heating water system by Navien, done in time before the cold weather came, and adds that when a pipe burst in those cold days in December 2024 they came without hesitation and fixed the problem. Brian is the name that comes up in the September 2024 reviews — one says he has helped their family repair leaks and old pipes proactively, and serviced their boiler to keep the house warm in the winter. Its Massachusetts plumber license 3743-PL-C is expired on the state registry. Water heaters, a burst pipe and a boiler in winter are the jobs 2024 customers describe hiring them for.

Brian is the best plumber I know. He has helped my family repair leaks, old pipes proactively to avoid future damages in my home. He also serviced my boiler to keep my house warm in the winter. He is the only person I will call for a job in need. The service is top notch. The value for what you pay you wonâ t find anywhere else. Heâ s got years of experience and to find someone who is skilled in a trade and honest with you is incredibly hard to find. Do yourself a favor and call them.
