Ostroski Plumbing & Heating Inc.

Ostroski Plumbing & Heating is a North Billerica family business run by Greg Ostroski — a 2025 Reddit post describes the owner handing out his own cell number and being "extremely kind and helpful," with the poster staying loyal after Greg went out of his way for them on a house with undisclosed issues. The name says it plainly: this is both a plumbing and a heating outfit, and the reviews bear that out in roughly equal measure. The company holds a registry-verified, active Massachusetts plumbing license. Most calls described in the reviews are urgent — a failed water heater, a leaking pipe, a furnace that won't run — and the recurring theme is speed: callers describe technicians arriving within the hour or getting same-day service, even on short notice. Recent reviews from this summer describe a plumber arriving in under an hour to fix an issue without trying to sell unnecessary extras, and another calling the quotes quick and the work good. The reviews aren't just quick fixes, either. In a January 2026 review, one homeowner describes Greg finally diagnosing a years-long steam-heat hammering problem that multiple other plumbers and HVAC companies had failed to solve. Tankless water heater installs, furnace cleanings, boiler servicing, and leak diagnosis inside walls and ceilings all show up repeatedly across the 167 reviews on file dating back to 2022, most naming individual technicians — Brent, Stephen, Rob, Nick, and office coordinator Tina — by name. One clear exception stands out: in an October 2023 review, a customer describes a crew swearing on the job, not protecting the floors, and speeding away afterward in a way that drew a complaint from a neighbor. It's an isolated account against an otherwise long, consistently positive stretch, but worth knowing about. For plumbing or heating work that needs someone there fast — from a failed water heater to a heating problem nobody else could figure out — this is a family-run local outfit with an active state plumbing license and a long list of repeat customers.
