Maguire Company Inc.

Maguire Company is a Newton-based, family-owned plumbing, heating, and mechanical contractor now in its third generation; the company says it was founded around 1922 by Michael J. Maguire and is now led by master plumber Dennis V. Maguire. Its Massachusetts plumber license is verified active, and its BBB profile carries an A+ grade, with the bureau recording 104 years in business. The reviews back up that longevity: several long-time customers describe using Maguire for decades — one for 22 years, another for more than 40 — citing dependable, on-time service, including for rental properties during cold-weather emergencies. One reviewer, a local electrician who hired the company for his own home, said he'd seen firsthand how knowledgeable the crew is across both plumbing and HVAC work. Recent reviews describe a wide range of specific jobs handled by name: Kevin diagnosing a ceiling leak and catching an improperly set toilet at the same visit; Luis diagnosing a water pressure problem, installing a pressure-reducing valve, and fixing everything the same day; Chris replacing a kitchen faucet, fixing a gas leak, and adjusting a boiler's hot water temperature in one visit; and Andy completing preventive maintenance on a mini-split system. Across dozens of reviews, the same themes repeat: technicians who show up on time, explain what they're doing, and clean up when they're done. The one clear exception is old: a 2015 review on Angi described being stood up for a scheduled visit and a furnace with a burning smell that the technician chose to let 'burn off' rather than repair. It's the only negative account on file, and it predates the rest of the written history by nearly a decade. For plumbing and heating work in the Newton and Boston area, this is a century-old, family-run operation with a verified license, an A+ BBB rating, and a large, current, specific written history — with only one clearly dated complaint standing against it.
