## The honest read

E.F. Winslow Plumbing & Heating (also doing business as E.F. Winslow Home Services, with a design-studio arm for kitchen and bath work) is a Cape Cod home-services company based at 947 MA-6A in Yarmouth Port. The company describes itself as family-owned and operating since 1971, working across plumbing, heating and cooling, electrical, generator installation, and kitchen and bathroom remodeling.

Customers who hired them describe consistently thorough, specific work across those trades. Google and Houzz reviewers from 2018 through early 2025 credit the company with a full master-bath renovation that included a steam shower and a gas boiler install, a mid-winter furnace repair after a gas flue kept failing, an urgent AC fix completed overnight at a vacation rental between guest turnovers, a water heater installation and code-compliant plumbing repair, and electrical work replacing lighting and outlets. Reviewers repeatedly note prompt scheduling, clear communication, and technicians who finish work as promised — Google shows 4.3 stars from 3 ratings and Houzz shows 4.2 stars from 14 ratings, with a Houzz Award and two Houzz Badges attached to the profile.

More recently, though, the picture is mixed. The single review from the last six months — dated June 2026 — describes the opposite experience: two scheduled appointments with no one showing up and no communication from the company. Two older reviews, from 2018 and 2019, also mention minor scheduling friction — a job that ran a little longer than expected and a repair that waited on parts — though both still rated the work positively overall.

Licensing is worth confirming directly before booking. The company's own site lists six Massachusetts registration numbers across its trades, and BuildZoom's permit records (3,283 tracked projects, a BZ Score in the 89th percentile of Massachusetts contractors) show its Home Improvement Contractor number as active. But the only number the state's own registry returned a match for in this scan — 12298, which the company's site labels 'Master Plumber' — comes back as an expired HVAC/sheet-metal license held under an individual's name with no evidence connecting that person to this business, so it should not be read as a confirmed credential either way.

For plumbing, heating and cooling, electrical work, or a bathroom remodel on Cape Cod, E.F. Winslow has a long and mostly well-documented track record — worth asking specifically about current scheduling and confirming the active license number directly with the state before committing to a date.

**Strengths:**
- Multi-trade reviews — plumbing, HVAC, electrical and remodel work praised 2018-2025
- Emergency response — reviewers describe fast fixes at midnight and mid-winter
- Detailed remodel work — cited steam-shower master bath and gas boiler install
- Long operating history — self-reports serving Cape Cod since 1971

**Concerns:**
- Recent no-show report — a June 2026 review cites two missed appointments
- Licence not confirmed — the state's only matching record is expired and under another name
- Occasional delays — two older reviews mention parts or scheduling running long

**Where sources disagree:**
- Houzz lists a licence number (Ma Lic #: 7939) that matches none of the numbers the business publishes on its own site or that appear on BuildZoom.
- The only state-registry hit for a number the business self-reports (12298, self-labeled Master Plumber) is typed as an HVAC/sheet-metal (SM-M1) license, shown expired, and held by an individual (Joseph N Lamparelli) with no evidence connecting them to this business — this cannot be stated as this business's verified or lapsed credential.
- BuildZoom marks license #3281 (Plumbing Business, matching the business's own 'Registered Plumbing Corp: 3281') as 'License Not Verified' even while showing it Active with a May 2026 expiration, and separately calls its Home Improvement Contractor license #132379 its own 'Verified License' — the two directory claims carry different confidence despite both matching numbers the business self-reports.
