Mana Mechanical Service Inc

Mana Mechanical's story is told in permits rather than reviews. BuildZoom counts 37 permitted projects for the Randolph company at 57 Rockefeller Street, 33 of them inside the last three years — 17 in 2023, 11 in 2024, four in 2025 and one so far in 2026 — at a typical permit value near $6,050, with Melvin Martinez listed as owner. Read what those permits actually describe and a plumbing shop appears. Bathroom and kitchen rough-ins, water heaters, combi boilers, gas piping, drain and vent work, pulled across Brookline, Braintree, Milton, Revere, Malden, Brockton, Needham Heights and Taunton. Worth flagging: BuildZoom's own summary line calls the company mostly an HVAC and home-addition outfit, which its own permit descriptions do not bear out. If you are calling about a heating system rather than gas and pipe work, establish that first. On paperwork, take care. BuildZoom lists a Massachusetts Master Plumber licence, number 12507, class Master, and shows the status as active — but the site expressly marks that entry "License Not Verified" and says the expiration date it saw was May 2026, which has since passed. That is a directory's record, not a registry check made here, so ask for the current licence number and confirm its standing yourself. The other thing to know is that nobody's account of the work appears anywhere: BuildZoom reports no customer reviews for the company, and no review site here carries any either. The permit trail says a genuinely working shop that pulls its own paperwork and keeps at it year after year; it says nothing about how the finished job looks or how the crew is to deal with. A reasonable call for gas fitting and residential plumbing around Randolph, Milton and Braintree. Before booking, ask for the licence number and its current status, and ask for two or three references from the towns in that permit list.
