D&G Exteriors is a Beverly-based exterior specialist — roofing, siding, windows, decks, trim and gutters — with John (and often Shane) named as the crew leads across a remarkably deep record of reviews. The thing that keeps coming up isn't just craftsmanship, it's restraint: several homeowners describe being told a targeted repair would do the job when a full roof or siding replacement would have been the easier upsell. The record runs to 156 reviews from 2023 through today, 66 of them in just the last six months, with zero negative in that stretch. Its Massachusetts home improvement contractor registration is active, and it holds a 5★ average on both Google (161 ratings) and Thumbtack (15 ratings). The specifics are what carry it: an Ipswich homeowner whose roof had leaked through a valley for years despite prior repairs finally got it fixed when John reworked the flashing detail properly; another described being handed a phased plan that tackled urgent roof and water damage first and siding and windows later once budget allowed; a 100-year-old Ipswich home got new siding and rebuilt trim done in a way that "respects the character of the house while actually protecting it," and held up through two storms afterward. On a 14-window Marblehead job, the homeowner chose D&G after interviewing five contractors because John was the only one who measured every opening rather than eyeballing it; in Hamilton, after getting quotes from six or seven companies, a homeowner picked D&G because John was the one who explained not just what they'd do but why. Coastal-exposure homes get called out specifically — jobs in Gloucester, Manchester-by-the-Sea, and Beverly's own shoreline weather. There's little here to flag as a concern. The closest thing to a wrinkle across dozens of reviews is one customer noting a siding, door and window project ran a little longer than planned — attributed to the crew being "really diligent about doing it right," not to any fault. For roofing, siding, window or deck work anywhere on the North Shore, especially a coastal-exposure home, this is about as deep and consistent a record as they come — the main thing worth checking is scheduling, given how in demand the reviews suggest they are.
We put a standing seam metal roof on our Salem colonial and it's the best decision we've made on this house. Looks incredible, snow slides right off, and we're done thinking about our roof for the rest of the time we live here. John was great about explaining the differences between metal and shingles without pushing us either way. Really happy with D&G Exteriors.
We had a section of our roof that was leaking every time it rained hard from the east. John came out, found the problem, and had it repaired within a week. No pressure to replace the whole roof, just fixed what needed fixing. Leak is gone. Really appreciated the honest approach.
Called them about some siding that blew off during a storm. They came out fast, matched the existing material, and patched it so you can't even tell where the damage was. Quick, professional, reasonably priced. Exactly what you want in that situation.
Needed a deck torn down and rebuilt in Manchester-by-the-Sea. The old one was unsafe. Soft boards, wobbly posts, the whole thing moved when you walked on it. D&G built a new composite deck that's solid, looks clean, and should last a long time without the maintenance headaches we had with the old pressure treated wood. They also adjusted the layout so we actually have room for a table and chairs now, which the old deck never really allowed. Smart design and solid execution.
What an awesome job D&G did on our roof. The work was top of the line. They were done in 1 day even though there was a lot extra work that had to be done before the roof could be replaced. I would not hesitate to hire the group of workers again. They have a great team working with them
