Jack just completed an addition to their home, a recent Google customer said, describing him as organized, efficient, responsive and knowledgeable; that customer said he also built their neighbors' home about six years ago. Strong Builders, which Houzz lists in Upton, says on its website that it builds and remodels homes — new homes, additions, kitchens, bathrooms, basements, garages, decks, screen rooms and porches — with design and plans handled in-house, and that it brings over 30 years of building and remodeling expertise. Its Massachusetts home improvement contractor registration, number 180216, is active on the state registry.
A recent customer said Samuel came out, recognized drainage problems off their roof and offered a very fair price, and that his crew fixed the issues from the prior installation. A 2026 customer said Strong Builders did a full remodel of their kitchen and praised Jack's transparency throughout the process.
A 2025 Google customer said Strong Builders replaced their old, rotting carport and deck with a new one-car garage and composite deck. That 2025 customer described Jack as largely a one-man operation and said the few subcontractors he brought in handled electrical and concrete work. A 2025 Google customer said that on a kitchen remodel Jack was there 6 days a week, 8-10 hours a day.
A 2024 customer said Jack built a 16x18-foot family room with a 16-foot cathedral ceiling and completed almost everything himself, from framing and siding to sheetrock, hardwood floor and painting. That 2024 customer said Jack provided daily updates and was transparent about costs. A 2024 customer said Jack designed and built a family apartment and screened porch and added a separate bedroom and bath to the main house, doing 90% of the job by himself.
A 2023 customer said Strong Builders remodeled their basement and added a bathroom. A 2023 customer said Jack finished a new deck in a week once the materials arrived, with the screws hidden "so the walking surface remains smooth." A 2022 customer said Jack screened in a second-story deck, created the plans and worked with the town to get permits, which the customer said in Grafton is not always easy. A 2022 customer said Jack finished a basement bathroom and refinished the basement floors, on time and on budget.
A 2021 customer said Jack tore down an existing deck and built a new one, coordinating the permit, the supplies and a subcontractor for the footing, and coordinated the building inspector's sign-off.
