PowerHorse Plumbing LLC

Twenty-eight ratings on Google, every one of them five stars — and a company that has only existed since 2023. That combination is the first thing to know about PowerHorse Plumbing, a Methuen shop run by Justin Pen that the site says serves the Merrimack Valley and southern New Hampshire, doing residential and commercial service, renovation and new-construction plumbing. The jobs people describe are the ordinary emergencies and punch lists of a house. This spring one customer had a pipe break; the owner and another plumber were out that morning, stopped the leak, laid out repair options at different price points, and hauled away the soaked insulation. Another had a run of faucet, shower, toilet and laundry-line fixes — the estimate came back within 24 hours and the work was done inside the week. A landlord used them at an investment property in March and singled out being kept in the loop for the whole job. The credentials check out where it counts: its Massachusetts master plumber license, 16926-PL-M, is active with the state. The BBB page shows an A+ grade, without accreditation. BuildZoom scores the company 93, above 73% of Massachusetts contractors, and its 2025 permits are real gas and plumbing work — a chimney-vented gas boiler swap, gas piping for a tankless unit and two furnaces, and a $25,000 plumbing renovation. Two things to sort out before booking. The company is young: incorporated in September 2023, with the whole review history packed into roughly the past year, so there is no long track record to lean on the way you could with a thirty-year shop. And the corporate plumbing-business registration, #5022, is only a directory's listing — BuildZoom flags it as unverified, with a May 2026 expiration — so ask for current registration and insurance certificates directly. Right call for a Merrimack Valley homeowner who wants a licensed plumber for a leak, a water heater, a boiler or gas piping, and who values a fast estimate and a clean job site. Confirm the business registration and insurance, and get the scope in writing — the reviews suggest that is not where this company struggles, but it is what you check on any two-year-old business.
