Family-run since 1922 — now three generations under a master plumber
What does plumbing work cost in Greater Boston?
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Maguire Company Inc.. Use it to sanity-check bids, then get the real number in writing.
Maguire Company has been fixing Newton-area plumbing and heating problems since 1922, when Michael J. Maguire started the business; the company says it's now family-owned across three generations, led by master plumber Dennis V. Maguire. The volume alone says something — 36 reviews on file average close to perfect, and the same names recur review after review: Kevin, Chris, Dave, Andy, Luis, Anthony.
What people describe most often is attention that goes past the original call. One customer phoned about water stains on a garage ceiling and got the leak traced AND a nearby toilet — set incorrectly — reset in the same visit. A local electrician who has hired Maguire at his own home describes watching the crew handle both small jobs and winter emergency boiler swaps firsthand. Reviewers who've used the company for a decade, 22 years, even 40 years, describe the same pattern: on-time arrival, clean work, technicians who explain what they're doing before they start.
The written record does include an older complaint. In a 2015 review on Angi, a customer described being repeatedly stood up for scheduled furnace maintenance visits and felt the quoted price ran about $300 above a competitor's — a genuinely bad visit, even if it sits well outside the recent run of five-star write-ups.
Its Massachusetts plumbing license is active, and the Better Business Bureau lists the company at an A+ grade. On its own site, Maguire also points to affiliations with Associated Builders and Contractors, Habitat for Humanity, and an ESGR Above and Beyond Award for supporting employees who serve in the National Guard or Reserve.
The mix skews toward residential plumbing repairs — faucets, water heaters, toilets, pressure-reducing valves, gas line work — with heating and mini-split maintenance handled by the same crews. For anyone in Newton or the greater Boston area weighing a call, this reads like a shop people keep coming back to for decades, with one dated exception worth knowing about before booking a maintenance contract.

Fantastic, reliable service. They always go above and beyond to solve the issue at hand. Highly recommend!!!
Called Maguire because of water stains on garage ceiling. Kevin from Maguire found the source of the leakage and also found that a nearby toilet was incorrectly set, which he reset. I was very happy with ease of scheduling as well as quality and thoroughness of service.
These folks do exactly what they say and they do it on time.
They clean up after themselves and smile as they go.
Dennis and Anthony and Dave and Jack represent this company with elegance.
Pricing is reasonable.

We’ve been using Maguire for many years for all of our heating and plumbing needs, and they are always prompt, efficient, and courteous. Our most recent plumbing problem was dealt with most professionally by Kevin, who came shortly after we called the office about a leaking toilet . He diagnosed the problem, gave us an estimate, went to get the parts, and completed the repair. We have complete confidence in the Maguire team!
