DeRienzo Plumbing is a Middleborough, Massachusetts outfit that keeps showing up in reviews for one reason: fair, no-surprises pricing on top of showing up when they say they will. The company's own site describes plumbing, heating and gas-fitting work for homes and businesses across the South Shore and Greater Boston, and its Massachusetts plumbing license (5197-PL-C) is active on the state registry.
Reviewers name the same person, Tony, on job after job, and in a cluster of 2025 reviews they describe specific work: replacing a water heater the next day after it failed, swapping two toilets and stopping a bad leak, installing a washer and dryer, and — for one customer who'd just moved in — replacing bathroom fixtures, fixing a leak and replacing an emergency water shut off valve. "Fast responses, great pricing, never late," one 2025 review put it. All ten reviews on file, running from 2025 into mid-2026, are five stars, and the newest, from this past June, calls the pricing "fair and reasonable with no surprises" with the crew arriving on time. Town permit records tracked by BuildZoom show 28 projects, adding a paper trail of completed jobs behind the reviews.
Nothing here raises a flag — no complaints, no pricing disputes, nothing unresolved. One thing worth knowing going in: Tony works with a crew, but he's named directly on nearly every job, so scheduling may still hinge on his own availability.
DeRienzo is a strong call for routine plumbing and heating work — water heaters, fixture swaps, leak repairs — from a South Shore crew reviewers keep coming back to; worth confirming turnaround time for anything outside standard business hours.
