# NMTI General Contractors

**Trade:** Roofing · **Address:** 35 Village Rd #100, Middleton, MA 01949, USA · **Phone:** (781) 502-8779 · **Website:** https://nmticonstruction.com/ · **Languages:** English

**Rating: 4.2/5** (medium confidence) — from 22 reviews across 5 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.
100% of sentiment-scored reviews read net-positive. Last 6 months: 0 reviews, 0 negative.

## The honest read

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.

**Strengths:**
- Hidden damage — spots issues under shingles other bids miss
- Named crew leads — Ramon and Juan repeatedly praised
- Spotless cleanup — crews leave job sites clean
- Multi-trade projects — handles additions and full remodels
- Veteran owned — Angi lists veteran owned and operated

**Concerns:**
- Years-in-business mismatch — Angi's About and badge disagree

**Where sources disagree:**
- Angi's profile states 24 years in business in its About text but 28 in its Business Highlights badge
