Duncan Plumbing & Heating Inc

Duncan Plumbing & Heating is a family-owned plumbing and heating company based in Norwood, Massachusetts, that says it has been at it for 35 years, run hands-on by master plumber Dwight Duncan. Better Business Bureau's file backs up the tenure, putting the company at 36 years in business with Dwight Duncan listed as owner, and gives it an A+ rating even though the company has never sought BBB accreditation. Its own site lists ten towns it covers, including Norwood, Canton, Dedham, Needham, Sharon, Walpole and Wrentham. On Google, the company holds a 4.4-star average across 14 ratings. In a September 2025 review, a customer called in the morning and Dwight answered immediately; by noon, a technician was on site working on the boiler, and the customer praised the efficiency and communication. A month earlier, another customer described a technician named Jeremy handling a multi-faceted plumbing project at a condominium complex, calling the work quick and thorough. In an August 2024 review, a customer described a technician who double-checked and examined a plumbing issue that had been causing trouble for months before pinning down the cause. Not every account is positive. A 1-star review from October 2023 described being hung up on repeatedly within a ten-minute span while trying to reach the business for service, and warned others not to bother calling — a notable exception in an otherwise consistent run of praise, including a November 2022 review describing a quick on-site visit with the needed parts already on the truck. BuildZoom lists two active Massachusetts licenses for the company, a Plumbing Business registration (#3111) and a Master Plumber license (#13384), both with an expiration on file of May 2026 — a directory listing, not something verified against the state registry directly, so it's worth double-checking given the phone-reachability complaint above. For plumbing or heating work in Norwood and the towns it says it covers, the reviews point to a company that generally moves fast and does careful diagnostic work under its owner's direct involvement. Confirm they're answering the phone reliably before booking, since that's the one recurring gap in an otherwise strong record.
