Dube's General Contracting works out of Nashua on the kind of projects that run for weeks rather than days — additions, attic and garage conversions, whole-house siding, decks and porches, kitchens and bathrooms, and window and door replacement. Its Google profile averages 4.8 stars from 83 ratings, the Better Business Bureau grades it A, and its BBB page lists a Massachusetts home improvement contractor registration, number 199509, as that bureau's record rather than a verified one.
The reviews read like the same people over and over: Josh in sales and estimating, Adam as project manager, and a crew named again and again — Paul, Bruce, Evan, Patrick. Customers describe daily updates, an online portal showing schedule and photos, and project managers on site through the job. A June 2026 customer had a 600-square-foot attic finished around a complicated roof line and said the multi-month schedule held. Another that month had a chronically leaking skylight removed and the damaged roof, wall and ceiling rebuilt for less than they expected to pay.
The range is unusually wide for a firm this size. In a 2025 review, a customer had a detached garage converted into a commercial kitchen and office; another had a home resided in custom-cut James Hardie to match an unusual original style; a 2024 customer had 12 windows replaced across six rooms; and in a 2023 review, a customer had exterior rot repaired and a badly built deck levelled. Several describe the company coming back long after the fact — a February 2026 customer had baseboard caulking on a four-year-old sunroom addition fixed within a couple of weeks of asking, and a 2024 customer had repeat visits to solve a fireplace draft after an addition.
The two serious complaints are both from the same period and worth reading. In a December 2022 review, a customer said they paid a $9,800 deposit in July for a screened porch, then chased updates into September without a start date. In a September 2023 review, a customer who spent six figures on an exterior and siding project said the finished result looked great but that it took more than twice the quoted time, that items reported as ordered had not been, and listed code problems — a dryer vent left venting into the wall, a stove exhaust covered by house wrap. A November 2022 four-star reviewer, happy with the result and the budget, called the scheduling haphazard.
For a multi-week renovation where you want one project manager and daily visibility, this is a deep record with a lot of specific, repeat business behind it. Get the schedule, the deposit terms and the inspection sign-offs written into the contract, and ask who is on site each day.
