N7 Construction

Eleven reviews spanning five years and two platforms, and every single one is five stars — that's the record behind N7 Construction, a Melrose, MA outfit built around decks, porches, and the finish carpentry that goes with them. The most recent word, from August 2026, describes the crew swapping a kitchen window for a sliding patio door and building a brand-new deck, arriving early every day of the job. That pattern holds across the years: in a 2025 review, a homeowner who'd struggled to find a contractor they trusted said N7 built their screened porch and left them thrilled; in a 2024 review, another homeowner said owner Fernando replaced a side porch in three days with hands-on oversight of the crew; and in a 2021 review, a customer credited the team with replacing soffits and window trim and rescuing a porch a previous landscaper had damaged. Beyond decks and porches, N7's own website lists a fuller construction menu — framing, siding, roofing, window and door installation, demolition, remodeling, and room additions — across towns including Brighton, Haverhill, Marblehead, and Roslindale. The company says on its site that it has grown steadily since its founding in 2019 and puts its experience at seven years; its Thumbtack profile, where it holds 2025 Top Pro status and a completed background check, states five years instead — a small mismatch between its own two self-reported figures. For a deck build, a porch rebuild, or finish carpentry work, the written record here is consistent and detailed enough to trust; worth asking directly about the broader remodeling and roofing work, since the reviews on file are almost entirely about decks and porches.
