Hennigan's Plumbing & Heating, LLC

Hennigan's Plumbing & Heating came up on Nextdoor the old-fashioned way: in an April 2025 post out of Centerville, a poster recommended Keagan Hennigan by name and passed along his phone number. The company works out of Carver and holds Massachusetts plumber licence 5007-PL-C, active on the state registry under the company's own name. BuildZoom shows one permitted project for the business — a 2017 kitchen job in Braintree, where a leaking drain and the water piping were replaced and capped for new base cabinets. That is the plumbing side of a renovation rather than a single fixture swap. Its BuildZoom profile also lists mechanical work, sheet metal work and HVAC, which fits the heating half of the name. A sensible call for licensed plumbing tied into a kitchen or bath project around Carver, or for heating work alongside it. Ask for a couple of recent local references, and get the scope and proof of insurance in writing before anyone starts.
