Hendo Construction INC

Hendo Construction is a Holliston, Massachusetts exterior remodeling shop run by Carlos Duy, offering roofing, siding, gutters, trim, painting, decks and custom countertops for homes and small commercial spaces. Its Massachusetts home improvement contractor registration is active, and the Better Business Bureau rates it A — not yet accredited, with the bureau citing its relatively short time in business (the file opened in 2024) rather than any complaint as the reason it isn't higher; no complaints or government actions are on record. The written record, more than twenty Google reviews stretching back to 2022, keeps returning to two kinds of jobs: decks and siding. Reviewers describe Carlos and his crew tearing down and rebuilding decks from scratch, and in a 2023 review, stripping and sanding an old mahogany deck — including its railings and spindles — before applying two coats of natural stain over two and a half days. On siding, a 2024 review described the crew finding hidden rot on the back of an 1890s house, fixing it stronger than before, swapping out three of the home's last original windows, and finishing the trim work inside, all done quickly. Multiple other reviews on siding replacements emphasize the same thing: costs explained upfront with nothing added later. The tone across reviews is consistently about communication and follow-through — reviewers mention Carlos personally explaining each step, adjusting to their preferences mid-project, and cleaning up fully when finished. A 2025 review even described a same-night repair-and-paint job on an entire office. A solid pick for exterior work — siding repair or replacement, deck rebuilds, trim and painting — in the Holliston area, backed by a verified license and a deep, consistently positive review history.
