Hendo Construction INC

Hendo Construction is a very small Holliston outfit — the Better Business Bureau records a single employee — and its owner, Carlos Duy, is the name customers write about. Its Massachusetts home improvement contractor registration, number 212563, is active and verified against the state registry in the company's own name. The work the reviews actually describe is exterior: siding, trim, gutters, decks and painting. In August 2024 a homeowner with a house built in the 1890s said Hendo found rot at the back and fixed it stronger than before, finished quickly, changed out three of the last original windows and did a neat trim job inside. In October 2023 another described a 15-to-20-year-old deck: several mahogany boards replaced, the whole deck including railings and spindles sanded back to its natural state, then two coats of natural stain, all finished in two and a half days by the owner and one worker. In September 2025 a customer had an old deck taken down and a new one built, and said Carlos explained everything he was going to do and cleaned up completely at the end. A June 2026 deck client said adjustments made along the way were accommodated without fuss. Pricing transparency is the other recurring note. A November 2023 siding-and-outdoor-lighting customer said everything was explained upfront with no hidden cost or added fees; an August 2023 siding customer said much the same and praised the cleanup afterwards. Two caveats concern the record rather than the work. All 22 written reviews sit on Google, all are five stars, and several are a single line — there is no independent second platform to cross-check against. And the BBB opened its file only in May 2024, grading the company A while citing length of time in business as a reason, so this is a young public record rather than a long one. Roofing leads the company's own website, but no review on file describes a roof.
