## The honest read

Dunphy Plumbing & Heating is Bill Dunphy — a West Harwich plumber who, by his own account, runs the company himself and does the work rather than sending a tech or a subcontractor. The state registry lists him as holder of an active Massachusetts journeyman plumber licence, #31699-PL-J, and his site puts his hands-on experience at more than twenty years across Harwich, Dennis, Chatham, Brewster and Yarmouth.

What customers write about first is the phone. In an August 2026 review, a homeowner whose gas water heater quit on a Friday afternoon and flooded the basement had two other companies quoting Monday or Tuesday; Dunphy answered and had it fixed the next day. A 2023 caller reached him on a Friday night over Christmas weekend and had him at the house by 10am the following morning, and another 2023 customer got a July 4th repair done in time for the party. A May 2026 couple who hit a boiler and plumbing leak the day they got into town describe him arriving immediately and declining to sell them anything they did not need.

The work clusters around water and heat. Water heaters run through the reviews in every form — a warranty hybrid electric unit he ordered, installed and hauled the old one away for in March 2026, a three-zone water heater and boiler, a tankless unit in a June 2025 job, and a twenty-year-old shower faucet he tracked down to match the rest of the bathroom's fixtures. On the heating side, a 2023 customer's failed gas furnace became a new furnace and matched A/C system installed within a week; others describe an oil-to-gas conversion in 2022, heat pump cleaning and repair, and gas lines run to a grill and to a fireplace converted from propane. BuildZoom shows 21 permits pulled, mostly gas, water-heater and plumbing work across Cape Cod towns.

The pricing notes are unusually specific for a plumber. A January 2023 customer said the invoice for a next-day faucet replacement and a new refrigerator water line came in lower than expected; a 2023 reviewer called the price for a same-afternoon water heater repair reasonable; a 2026 reviewer said the same about a three-zone water heater and boiler.

Two things are worth settling before you book. The company advertises 24/7 emergency service on its own site while its HomeAdvisor profile's FAQ states there is none, so ask directly what after-hours coverage means. And the operation is small by design — one licensed plumber plus a helper named in several reviews — so a scheduled job may sit behind an emergency. The written accounts live almost entirely on Google, where 62 ratings average 4.7; the Angi and HomeAdvisor mirrors carry none.

**Strengths:**
- After-hours response — owner answers the phone nights and weekends
- Water heater work — hybrid, tankless and multi-zone installs handled end to end
- Owner on the job — Bill Dunphy states he does the work himself
- Gas line fitting — grills, fireplace conversions and oil-to-gas changeovers
- No upselling — reviewers report only the needed work quoted
- Invoices under estimate — several customers call the bill lower than expected
- Verified plumber licence — MA journeyman 31699-PL-J active in the registry
- Hard-to-source parts — matched a 20-year-old faucet to existing fixtures

**Concerns:**
- Emergency coverage disputed — HomeAdvisor's FAQ contradicts the company's 24/7 claim
- One-plumber shop — scheduled jobs share capacity with emergency calls
- Single review platform — Angi and HomeAdvisor mirrors carry no reviews

**Where sources disagree:**
- The Google listing averages 4.7★ across 62 ratings, while every one of the 31 written reviews on file is 5★ — the star-only ratings behind that average include scores no written account explains, so the written material reads more uniformly positive than the platform headline.
- BuildZoom publishes two licence lines for this business: an active #31699 journeyman plumber licence and an inactive apprentice plumber licence #30414 (Class A) it says was at one point cancelled. The state registry verifies 31699-PL-J as active in William Dunphy's name; the inactive entry is a superseded apprentice credential, not an action against the current licence.
- The company's own site advertises 24/7 emergency service, and multiple reviewers describe after-hours and holiday callouts, but the HomeAdvisor profile's FAQ states no emergency services are offered.
- HomeAdvisor is a byte-identical mirror of the Angi profile and both show zero reviews ('This pro is new'), which sits against a Google history running back to 2021.
- Merged-listing residue: the 62-rating Google figure and the 31 written reviews come from listings for the same West Harwich business, now consolidated — the counts describe one operation, not two, and should not be added together.
