# Old School Plumbing & Heating

**Rating: 4.2/5** (high confidence) — from 24 reviews across 5 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.
92% of sentiment-scored reviews read net-positive. Last 6 months: 2 reviews, 2 negative.

## The honest read

Old School Plumbing & Heating works out of 19 Main Street in Dennis Port and holds a registry-verified, active Massachusetts plumber licence (4933-PL-C). The company describes itself as a team of four lifelong friends and Cape locals led by Master Plumber Sean Arone, covering residential and commercial plumbing, heating, gas lines and boilers with 24/7 emergency availability, and it self-reports serving the Cape from Falmouth to Provincetown.

What the review record is built on is emergencies. In a January 2025 review, a homeowner who found an active gas leak mid-day wrote that Sean rearranged the schedule so the crew could come the same day, arrived with the parts needed, and had the gas safely restored. A December 2024 reviewer, elderly and without heat at 29 degrees, said he offered to be there within an hour and kept in touch by text until the crew arrived and fixed the valve. A February 2025 caller reported phoning about a leak around 8am and having two plumbers at the house by 9:30. An October 2024 reviewer described a weekend failure of a Navien tankless heater being got running again.

The routine work draws the same notes. Reviewers in 2024 and 2025 describe a dishwasher, washer and dryer hooked up in a small cottage crawl space; a whole house re-plumbed with new shower hardware and an outdoor shower added; a new bathroom put into what one reviewer called a tricky antique home; a 35-year-old water heater replaced; an outside faucet fixed the day after the call. Tidiness and clean-up come up again and again, as do the technicians by name — Austin and Julian appear across several reviews.

The honest counterweight is recent. The two newest reviews on file, both from 2026, are one-star. The more serious one, from May 2026, is a service complaint rather than a workmanship one: the reviewer says an appointment was agreed for a specific date and time, nobody showed, and calls went unanswered. The other, from July 2026, is not about the work at all — the writer says they never hired the company and is complaining about how one of its trucks was driven. Neither describes a botched job, but the scheduling complaint is worth raising when you book.

For a Cape homeowner facing a gas leak, a burst pipe or a dead water heater, the pattern in the reviews is a company that answers the phone and turns up fast. Confirm the appointment in writing and ask who on the crew is coming, and check the current licence status yourself before work starts.

**Strengths:**
- Same-day gas response — 2025 reviewers had gas and heat restored that day
- Fast dispatch — a 2025 caller had two plumbers on site by 9:30am
- Whole-house repiping — a 2024 reviewer had the entire house re-plumbed
- Tidy work — reviewers repeatedly note thorough clean-up and care indoors
- Named crew — technicians Austin and Julian are praised by name
- Verified licence — Massachusetts plumbing licence active on the state registry

**Concerns:**
- Missed appointment — a May 2026 reviewer says nobody showed or replied
- Recent reviews — the only two from 2026 are one-star
- Driving complaint — a 2026 reviewer was cut off by a company truck

**Where sources disagree:**
- BuildZoom places the business in South Yarmouth, MA 02664 while the company's own site gives 19 Main Street, Dennis Port, MA 02639.
- BuildZoom categorises the company as HVAC, mechanical and sheet metal work, which does not match the plumbing-and-heating services the company and its reviewers actually describe.
