3R Plumbing and Mechanical

3R Plumbing and Mechanical works out of Pembroke, handling both plumbing and heating/cooling calls across the South Shore — the kind of business people call when a furnace quits in January or a water heater starts leaking at the worst possible moment. One reviewer describes the company as Veteran-owned; owner Ross appears by name across dozens of reviews, usually as the first call that gets things moving, backed by a recurring crew (Nick, Kaio, Marc, Kevin, Mitch, Yaz, among others). The volume here is real: Google shows 4.8 stars from 416 ratings and Thumbtack another 4.6 from 96, and the written record backs that up. The same names keep showing up for water heater swaps, tankless installs, furnace and boiler replacements, AC installs, and the occasional gas leak or burst pipe. A homeowner who rebuilt a fire-damaged house in Marshfield credited Ross, in a 2023 review, with handling three bathrooms, two kitchens and several gas appliances and with helping sort out the insurance side. More recently, a 2026 review describes a tenant left without heat and hot water for 24 hours getting a technician back the next day with the part already in hand. A few things are worth asking about before booking. The company's Massachusetts plumber license is registry-verified expired, and the Better Business Bureau gives it an F grade with 3 complaints on file. A handful of reviews spanning 2024 into 2026 also describe steep diagnostic or quote pricing: a 2024 review says a $650 charge for an hour of diagnostics came with no further explanation, another from the same year describes a $1,500 quote for a leaking vanity drain that a second plumber later did for $375, and a 2026 review describes being steered toward an unplanned AC cleaning after already paying roughly $2,000 for a heating-system repair. For routine plumbing and HVAC work — installs, replacements, and off-hours emergencies — the reviews back a crew that shows up and explains what it's doing. Get a second number for anything billed as pure diagnostics, and ask about the license status up front.
