# John Smith Plumbing **Trade:** Plumbing · **Phone:** (774) 212-5158 · **Languages:** English **Rating: 4.3/5** (medium confidence) — from 8 reviews across 3 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 0 negative. ## The honest read John Smith Plumbing is a Harwich, Massachusetts plumber holding an active Massachusetts plumbing license (32777-PL-J), verified directly against the state registry under his own name. His permit history places jobs across Cape Cod towns including Harwich Port, Chatham, Orleans, West Yarmouth, South Yarmouth, and Falmouth, with records on file going back to the 1990s. Reviewers consistently point to fast response on plumbing emergencies. In a 2026 review, a homeowner who reached out after seeing his reply to a social-media post said he installed a new water heater within the week at a reasonable price. In a 2023 review, a homeowner described waking up to a leaking water heater and being coached through shutting off the water by phone before he arranged same-day replacement. Another 2023 review described him correctly diagnosing and rebuilding a drain system that a home inspector had missed and a previous renovation crew had installed improperly. In a 2024 review, a homeowner recounted him replacing a failing water storage tank the night after the leak was found, on referral from a retiring plumber. Several reviewers across Google and BuildZoom, dating back to a 2020 review, describe his pricing as reasonable or fair and say they plan to call him again. The written record is thin in volume -- eight reviews across Google and BuildZoom since 2020 -- though every one is five stars and most describe a specific job rather than generic praise. One thing worth confirming directly: BuildZoom's own license page shows the license lapsed since 2016 and states "No active license on file," which conflicts with the active status the state registry itself currently shows under his name -- most likely a stale BuildZoom record rather than an actual lapse. He's a strong call for a Cape Cod homeowner facing a plumbing emergency, especially a failed water heater or a leak needing same-day attention, or a job where a previous contractor's work needs a second look. Given how few reviews exist, it's worth confirming current pricing and availability directly before booking. **Strengths:** - Water heater emergencies — same-day response and install repeatedly praised - Fair pricing — reviewers call him reasonable or fairly priced - Careful diagnosis — rebuilt a mis-installed drain a home inspector missed - Licensed plumber — active Massachusetts license verified under his own name **Concerns:** - Review volume — just 8 written reviews since 2020 - License status conflict — BuildZoom shows a lapse the registry does not **Where sources disagree:** - BuildZoom's licence page for this contractor shows License #32777 as lapsed since May 2016 ("No active license on file"), while the Massachusetts state registry verifies the same license (32777-PL-J) as ACTIVE under holder JOHN SMITH -- the registry is authoritative and the discrepancy looks like stale BuildZoom data, not an actual lapse. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Holds an active Massachusetts plumber license (32777-PL-J), registry-verified under the name John Smith, matching this business. _(confidence: high)_ - [State License Registry](https://occupationallicensingandpermitting.mass.gov/madol/s/license-search-page) — “MA plumber license 32777-PL-J registry-verified active — registry holder of record: JOHN SMITH” - Multiple reviewers describe same-day or next-day response for water heater emergencies and leak repairs. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xSeFRUbGxiSEJSYUdoSmNWYzRMVWhyZERWT2FHYxAB!2m1!1s0x0:0xa37324cdf3abfe1e!3m1!1s2@1:CAIQACodChtycF9oOlRxTTllbHBRaGhJcVc4LUhrdDVOaGc%7C%7C?hl=en) — “5★ I posted in a social media app seeking recommendations for a water heater replacement and thank goodness, I did.
