MDAC Construction Inc

MDAC Construction is a Medford general contractor whose reviews keep circling back to one thing: roofs. Nearly every third-party account on file, whether from Angi, HomeAdvisor or Google, centers on the same person, Marcio da Costa, walking homeowners through the work himself. On Google, the company holds a 5-star average across 18 ratings, and a July 2026 review credits da Costa with matching existing molding and laying new flooring in an older house with what the homeowner described as real care and attention. Earlier reviews from 2024, mirrored across Angi and HomeAdvisor, describe full roof replacements finished in a single day - on-time crews, a willingness to reschedule the final walkthrough around a homeowner's own schedule, and job sites left clean afterward. Its Massachusetts home improvement contractor registration is active, verified directly against the state registry under MDAC Construction Inc. BuildZoom independently confirms the same registration number, issued this April, and names Marcio da Costa as the owner. Angi and HomeAdvisor separately list a different trade license number for the business - a construction-supervisor-style number typically held by the individual overseeing the work rather than the company itself, so seeing two different numbers side by side isn't unusual. The company's own site advertises a wider menu - kitchen, bathroom, basement and attic remodeling, siding, and decks alongside roofing and general construction - but the third-party record so far only backs up roofing and that one flooring job. Anyone considering a larger remodel would do well to ask for recent examples of that specific work before booking. For a roof replacement or repair around Medford, the reviews describe a contractor who shows up, explains the process himself, and finishes on schedule.
