Provost Plumbing

Provost Plumbing is a plumbing and heating company based in Concord, MA. In a 2026 Google review, a customer said their HVAC company had been unable to fix a 9-year-old boiler and shut the heat off, and Russell was at the house later the same day they called Provost for a second opinion. That 2026 customer said Russell started with a thorough cleaning and checking the gas settings, and had the boiler and heat back up and running after only a few hours. A recent Google customer said the company made a house call on a holiday weekend. The company's own site says it was founded in 1960 by Leonard R. Provost and his wife and has continued as a family operation, with Delfina Nellie Provost as company president. The site also says it is certified in carbon monoxide testing and repair. Its MA plumber license 4745-PL-C, in the name of Provost Plumbing Heating & Cooling Inc., is expired on the state registry.

In a 2022 HomeAdvisor review, a customer said a leaky gas water heater past its expected lifetime was replaced rather than repaired, and that the tank had zero issues one and a half years later. A 2020 HomeAdvisor customer said Mike gave advice about a low-disruption, cost-effective solution and got the work done quickly. In a 2018 HomeAdvisor review, a customer whose bathroom tub would not drain after several services failed to fix it said the job was about replacing parts of a 90-year-old cast iron pipe, and that Russ called ahead with arrival updates. In a 2018 review about a steam heating system, a customer said Mike replaced a broken water level sight glass on the furnace and 2 radiator float valves, balanced the system, and fixed the problem in one visit for less than his estimated price. In a 2017 HomeAdvisor review, a customer said the price was very high and the technician tried to charge a consultation fee, which the office confirmed was an error. That 2017 customer also said they were very uncomfortable with the company's preferential pricing for customers enrolled in its plans.
