"I think ours could double as a bomb shelter." That is how a customer in October 2019 described the deck Walnut Hill Carpentry built for her, after learning that the company over-builds its decks on purpose, for safety and longevity. Decks and porches are most of the work customers describe. Robert deDiego — Bobby, to his customers — runs the Orange, Massachusetts company, which the Better Business Bureau lists at 16 years in business, also trading as Dediego Carpentry, accredited and graded A+. Both state credentials hold up: the home improvement contractor registration, 123507, and the construction supervisor licence, CS-106738, are active on the state registry under his name. HomeAdvisor and Angi list the business as veteran-owned and say it offers free estimates and warranties. The jobs go beyond plain decks. In September 2021 a customer had a flat deck replaced with a 4x8 front porch with solid railings, a rotted and mouldy front door swapped for one with sidelights, and the siding redone in brick. In May 2019 a homeowner had a deck torn down and rebuilt on a tight budget with a carpenter-ant infestation in the middle of it, and wrote that Bobby and his crew were neat and always showed up when expected. Finishing early comes up more than once: a porch built ahead of schedule in June 2023, and an October 2019 job that ran the same way, starting with a formal written proposal and a crew the customer called clean and thorough. Two things to weigh. The written history is dated — the most recent account is from November 2023 — and the platform averages differ a little: Google sits at 4.5 across 8 ratings, while Angi and HomeAdvisor, which mirror one another, both show 4.7 across 9. For a deck, a porch, structural carpentry or a barn repair around Orange and north-central Massachusetts, this is a strong call, and the over-building is the point of hiring them. Ask what the warranty covers, and get the written proposal customers describe before anyone starts.

Wonderful crew. Great work ethic. Love my new deck!
They build my porch ahead of schedule with great quality. The crew was very professional.
Did real good replacing porch, highly recommended for carpentry work
Everyone was professional, courteous, and highly skilled. They built a beautiful front porch, new front door, and replaced siding; we could not be more pleased.
I am happy because I am getting my deck done and he is a very nice man.
