Massachusetts plumber licence 4874-PL-C is registry-verified active and held in the company's own name, BONAFIDE PLUMBERS, LLC - the licence and the business are the same entity, which is the cleanest form this check can take. Google publishes a 4.9-star average from 98 ratings, and the written record runs from 2021 through 2026.
Customers name two people over and over: Marquis, who does the work, and Anela, who runs the phones and the schedule. A 2025 reviewer who had used them across a condo building for years listed burst water pipes, relocated gas pipes, water heaters, special-order parts for an aging building, sinks and shut-off valves, and described the pricing as fair and reasonable from up-front estimates. Older reviews describe the same range: leaking pipes and valves, a tankless conversion, toilet flange replacements, outdoor faucets, garbage disposals, dishwasher and gas range hookups, and steam radiator and baseboard heater work.
Diagnostic skill is the thread through the strongest accounts, and they are dated. In a 2023 review, a homeowner wrote that four plumbers had failed to find a bathroom leak damaging their kitchen ceiling and that Marquis found it within a few minutes. In a 2022 review, a family in a newly built home who waited nearly two minutes for hot water had a recirculating line run from the water heater to each bath and the kitchen - the reviewer said they then recommended their builder change plumbing contractors. A 2023 reviewer described a bathroom and kitchen roughed in and finished, a water supply line upgraded for building pressure, and a forced hot water loop with a unit heater, radiators and a manifold, all on time and on budget.
The caution in the record is one specific and serious complaint. In a January 2025 one-star review, a customer said they paid over $3,000 to replace a pump, the pump failed a week later, and they were told the company was busy on another job and to call someone else - ending in another $3,000 to fix it. That is a single account against many positive ones, but it is about warranty and callback, so it is worth asking directly what the guarantee is on parts and labour and who to call if something fails.
Worth knowing too: the written record has thinned recently, with one review in the last six months against a much denser 2023-2025 stretch, and the business's own site advertises weekday daytime hours rather than round-the-clock emergency cover.
They are a good call for residential plumbing repairs and replacements, hydronic heating work, and renovation plumbing where diagnosis matters. Get the warranty terms and the callback policy in writing alongside the estimate.
