GM Carpentry & Painting has been working out of Everett long enough to have a history, but almost none of it is written down where homeowners can read it. What the Better Business Bureau publishes is the spine of what is known: the company sits at 30 Baker Road in Everett, Geraldo Mariano is its president, and it has been in business 21 years — started in 2005, incorporated in 2010. BBB grades it A+; the company is not BBB accredited. Through that same profile it offers a wide mix for a carpentry shop: painting, decks, kitchen and bathroom remodeling, and general carpentry. The one outside look at the actual work is old. In July 2018, a Boston.com design story credited Gerry Mariano of GM Carpentry & Painting Inc. as the custom builder on a renovation, working with a designer he partners with often — a small but real sign that the finish work has stood up to a magazine's camera. So the written trail runs long on tenure and short on recent detail. If you are weighing them for trim, a deck, or a kitchen, ask for the addresses of jobs finished in the last year and for references you can call — the kind of specifics this company's public pages do not carry.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from GM Carpentry & Painting. Use it to sanity-check bids, then get the real number in writing.
A typical single-level deck is 12×16 — about 200 sq ft.
