Mario M Martin

Thirty-eight permits and not a single review. Mario M Martin has been pulling paperwork across Greater Boston for years — Everett, East Boston, Charlestown, Brookline, downtown Boston, Marblehead — and nobody has written down what it was like to hire him. His Massachusetts home improvement contractor registration and his construction supervisor licence are both active, and both are held in his own name. That combination matters: the construction supervisor licence is what lets him touch structural work, and his permit history leans that way. A $450,000 gut renovation in Everett that rebuilt a third floor. Brick cutting and pointing in East Boston, masonry repointing on a Brookline rear elevation. Kitchen and bathroom renovations with new electrical and plumbing in Boston's Fulton Street buildings. Typical permit value sits around $11,000, so the everyday work is much smaller than the headline jobs. In Marblehead he replaced stairs at 15 State Street in June 2023 under an Old and Historic Districts Commission emergency authorization — historic-district work, filed as a commercial permit. The matching demolition permit for that same address, D-11, carries a status of suspended. Two things worth raising before you call. First, a real share of this work is commercial rather than residential: a certificate of occupancy for a marijuana retailer and a $350,000 demolition-and-framing job at the same Malden address, and a daycare fit-up in Wakefield. Second, two Boston filings are code-enforcement work — removing an illegal basement unit to correct a violation, and confirming a building's occupancy as a two-family — which tells you he takes on the paperwork-heavy jobs, not that anything went wrong on his own. For structural or historic-district work in Greater Boston, the licensing and the permit trail are the strongest things going for him. What is missing is any customer voice at all, so ask for three recent homeowner references and, given the range, ask specifically about jobs the size of yours.
