McNish Building & Development

The most telling thing about McNish Building & Development is the size of what it takes on. In July 2024 the city issued a certificate of occupancy for three residential dwelling units at 11 McLellan Street in Dorchester, a job carrying a valuation of $755,715 — new construction, not a kitchen refresh. Two years earlier the same crew was stripping a Dorchester house back to sheathing for James Hardie siding, PVC trim, fourteen replacement windows and new front and back entry doors at $163,550, and refreshing a Commonwealth Avenue condo for $36,450. Its Massachusetts home improvement contractor registration is active and held in the corporation's own name. BuildZoom scores the company 105, which it places in the top 8% of Massachusetts contractors, and shows 23 projects on file. The company describes itself as established in 2010, a generational family business, and minority owned and operated with certification from the City of Boston — its own statement, not something confirmed here. It works as a design/build firm, running projects from concept through completion, with a service list that stretches from bathroom and basement remodels through decks, siding, windows, roofing and spray foam to accessory dwelling units and full additions, across Boston and a ring of nearby communities. Houzz puts its typical job between $15,000 and $50,000. The gap is written feedback. Across four sources there is exactly one published review — five stars on Houzz — and BuildZoom carries none at all. For a company with this much permitted work, that is a thin paper trail from customers, so lean on the permits instead: ask for the addresses of recent Dorchester jobs, and for references from the multi-unit work if your project is anywhere near that scale.
