Jansky Mechanical Corporation

A one-employee Quincy shop whose name keeps getting passed along by neighbors. Jansky Mechanical works out of 48 Cross St in Quincy under Robert Jansky, whose Massachusetts plumbing licence — 15288-PL-M — is active in the state registry. The company says it started in 2005 and now covers plumbing, heating and HVAC from Boston and Dorchester down through Canton, Milton, Braintree, Weymouth, Randolph and Hingham. The written history is short and old. HomeAdvisor holds exactly two reviews — a 4.5 average that is really one five-star and one four-star — and the newer of them dates to August 2018, when a customer wrote that the crew "did a thorough job and finished on time." The other is from December 2007. Those two are all anyone has written down. What is current is word of mouth. In March 2026 a Quincy neighbour answering a Nextdoor request for a small, independent, licensed plumber passed along Robert Jansky's name and number — the kind of unprompted referral that often tells you more than a star average, though it is one person's say-so and nothing more. The BBB page grades the business A+ with no complaints and no government actions listed, and describes a corporation incorporated in September 2005 with a single employee. That last detail is the practical one: this is a small shop, not a dispatch operation, and availability is worth asking about up front. Beyond the state-verified plumbing licence, the rest of the credentials are the company's own telling — a journeyman's licence, a master sheet metal licence, and refrigerant, oil-burner and OSHA 30 certifications, all self-reported rather than registry-checked. HomeAdvisor's category list runs to HVAC alongside plumbing, including central A/C and thermostat work. A reasonable call if you want a licensed, owner-run plumber for Quincy, Boston-side and South Shore work and you do not need a long public review trail to feel comfortable. Before booking, confirm scheduling and — if you are calling about heating, A/C or ductwork rather than plumbing — ask what he handles himself, since the plumbing licence is the one credential confirmed with the state.
