NMTI General Contractors

NMTI General Contractors works out of Middleton, doing roof work but also full home projects — additions, kitchen remodels, decks, foundation repairs — for towns on the North Shore. The line that keeps showing up in its reviews: crews that show up, communicate constantly, and leave the site spotless when they're done. Its written record runs 2021 through late 2025 — 22 Angi and Google reviews, every one on file a straight 5 stars, with Ramon, Juan Carcamo and Wilson named again and again as the people homeowners actually dealt with. The jobs range from small (a garage gable's flashing, a gutter repair) to large: one homeowner hired them to replace an entire roof after Ramon diagnosed hidden water damage under the shingles that other bids missed, another had them take down a wall and reroute plumbing for a full kitchen remodel while also patching a foundation crack, in a 2022 review, and a third describes a 3rd-floor master suite addition, in a 2024 review. On a large, complex Victorian roof, in a 2023 review, the crew started before dawn and worked past dark to finish in 2.5 days. Angi lists the company as veteran owned and operated and OSHA certified, and its Massachusetts home improvement contractor registration is active. Ratings differ by platform — 4.3★ from a dozen Google reviewers against a perfect 5.0 across 38 on Angi — worth knowing going in, though nothing in either points to a bad job. One thing to flag before calling: Angi's own profile page gives two different numbers for how long NMTI has been around — 24 years in the About text, 28 in its Business Highlights badge — so don't take either as gospel; ask directly. For anything from a leaky roof to a full remodel that needs multiple trades coordinated under one crew, NMTI's record backs it up — just confirm scope and timeline with Ramon or Juan before signing.
