Strong Builders is a one-owner operation based in Upton that homeowners hire for the big stuff — additions, decks, screened porches, basement remodels — the kind of project where a house grows a room instead of just getting refreshed. Run by Jack Whealan, the company states it brings more than 30 years of building and remodeling experience to each job, and its self-reported service area stretches through the Blackstone Valley and MetroWest towns: Northbridge, Grafton, Hopkinton, Westborough, Holliston and a dozen more nearby communities.
What stands out across the 27 reviews on file — spanning 2021 to 2026 on Google, Angi, HomeAdvisor and Houzz — is how often the same two project types repeat: additions and decks, built with a level of hands-on involvement customers mention by name. A 2024 review describes a 16x18-foot family room addition with a cathedral ceiling where Jack was on-site every day and did almost everything himself — framing, siding, windows, roofing, sheetrock. Another 2024 review, a bigger job adding a family apartment, a screened porch, and a new bedroom and bath, says he handled about 90% of that one solo too. Deck work comes up just as often: a rotting carport and deck rebuilt into a one-car garage with a composite deck in 2025, a second-story screened deck in 2022 that navigated the town's permitting process in Grafton, and a straightforward deck teardown-and-rebuild going back to 2021.
Communication and pricing come up unprompted, across different years and different reviewers: several describe clear quotes, no cost surprises, and Jack staying true to his original numbers even on jobs that ran into town permitting. One 2022 review said the experience "renewed my faith in contractors." A kitchen remodel from early 2026 and a basement remodel with an added bathroom from 2023 both drew the same praise — a clear plan up front and steady attention to detail through to the finish.
There's no complaint on file here: the company holds an active Massachusetts home improvement contractor registration, carries an A+, accredited rating with the Better Business Bureau, and its Google, Angi and HomeAdvisor scores all sit at 5.0. The one thing worth confirming directly is scheduling — Jack does much of the physical work himself, so lead time on a bigger project like an addition or a full remodel is worth asking about up front.
For a homeowner planning an addition, a deck, a screened porch, or a basement buildout in the towns Strong Builders serves — Northbridge, Grafton, Hopkinton, Westborough, Holliston and more — this is a long, detailed review history built almost entirely on that exact kind of project, worth a call to check current availability.
