Castle Construction is a Mansfield, Massachusetts general contractor run by Bill, whose Massachusetts home improvement contractor registration (#191881) is active, verified against the state registry — HomeAdvisor and Angi both list the same number as valid through May 2028. The company's own site describes residential and commercial remodeling and new-construction work, including kitchens, bathrooms, additions, and outdoor living spaces, and Houzz shows the firm working across dozens of towns beyond its home base, including Sharon.
Reviewers spanning a decade keep landing on the same two things: Bill stays in touch, and he adapts when a job changes shape. In an August 2026 review, a homeowner described a full bathroom remodel — new vanities, tile flooring, and a walk-in shower — calling the crew professional and easy to work with start to finish; days later, another review described the team rebuilding three bathrooms, a kitchen, and a basement after a burst pipe, calling them responsive and willing to make requested changes. Older accounts tell a similar story: a December 2021 review described Bill finishing a basement while keeping the homeowner in the loop, and a February 2016 review called him professional and friendly through the whole project. In a May 2016 account, radiant heating elements found in a ceiling forced a change of plan mid-job; the crew removed the original materials without complaint and brought in a painter to finish the repair a different way.
Worth asking about: a September 2016 review called the pricing on the higher side, even while praising the crew's helpfulness and availability.
With a decade-long, if modest, written history and a verified state registration, Castle Construction is a reasonable call for a Mansfield-area bathroom remodel, basement finish, or post-damage repair — worth a conversation about pricing upfront given the one dated note on cost.
