Provost Plumbing

The company says it's been fixing pipes and heating systems out of Concord, MA since 1960, when Leonard R. Provost and his wife started it; today it says the business is still family-run, led by their son and son-in-law William R. Coombs, who joined in 2009 and holds master plumber and master sheet metal licenses. The company also describes itself as veteran-owned. Reviewers keep naming the actual people who show up — Russ, Bill, Mike — rather than praising in the abstract. In a March 2026 review, a homeowner described calling Provost for a second opinion after another HVAC company had shut off their heat over a nine-year-old boiler; Russell was at the house that same day, walked them through why he disagreed with the earlier diagnosis, and worked through cheaper fixes before recommending a replacement. Older accounts tell a similar story: in a 2018 review, a customer described Russ diagnosing and fixing a stubborn tub drain other services had given up on; in a 2020 review, Mike found a low-disruption, cost-effective fix; and in a January 2018 review, Mike repaired a steam heating system in one visit for less than his own estimate. On HomeAdvisor, where the company has a longer public track record, it holds a 4.8-star average from 137 ratings, 84% of them five stars. The one sour note on file is an August 2017 review where a customer called the price very high and said a technician initially tried to charge a consultation fee before the office corrected the error — worth asking about pricing and fees up front. The company's own site lists a Massachusetts plumbing license number, but that hasn't been independently verified against the state registry, so it's worth confirming directly. For plumbing and heating repairs — water heaters, boilers, steam systems, stubborn drains — this is a company whose customers keep calling back the same technicians by name over nearly a decade of reviews. Its site also lists kitchen and bathroom remodeling among its services, though the reviews on file describe repairs and installs rather than full room renovations, so ask specifically about remodel experience if that's the job.
