MacLellan Plumbing & Heating is a family-owned Weymouth plumbing and heating company that says it has served the South Shore for more than 25 years, covering Weymouth, Braintree, Milton, Hingham and Quincy. The state registry lists Massachusetts master plumber licence 10311-PL-M in the name of Martin MacLellan, and BBB grades the company A+. Google shows 4.4 stars from 9 ratings. The most recent review is a complaint. In August 2025, a customer said Marty repaired a leaking toilet tank in October 2024, the fix lasted only until May 2025, and they had to call again. The older reviews are positive. A February 2023 customer said the company helped figure out a leaking furnace and repaired it efficiently, and a September 2023 reviewer said a leak was fixed quickly. In a November 2022 review, a customer said the office called back the same day and talked through the problem even though no one was available to come out. A 2021 reviewer said Marty explained the installation in detail.
I hired Marty to do a toilet tank repair because it was leaking. And the first repair happened in October 2024 . The first fix only lasted from October 2024 to May 2025(around 7 months). They come in again to replace the seal again because the toilet is leaking again in May 2025. Unfortunately, the leak has returned yet again as of late July 2024, despite both prior repairs. This second repair lasted barely 2 months. At this point, I’ve paid nearly $450, and I’m still left with the same unresolved issue. That’s incredibly frustrating, especially since this was supposed to be a straightforward fix. The owner refuse to take ownership on his work and blame it on everything else. So please do not hire this company.
Responsive. Fixed our leak quickly. Super. Won't use anyone else.
I can't say enough about MacLellan Plumbing and Heating. They went over and above helping me figure out a leaking furnace problem and then repaired it efficiently. The technicians were helpful, knowledgeable and courteous. VERY high praises for this company. Maureen A.
Great customer service. I left a message asking for a visit. They called back the same day, and even though they did not have the availability to come and provide service, they took the time to discuss the issue with me at length and provided useful advice, feedback and proposed alternative service providers.
Marty is experienced and explained every bit of process and installation questions in details. Highly recommend.
