B.M.W Builders

B.M.W Builders is a husband-and-wife design-build firm in Harwich run by Ben Welsh, who handles construction, and Tiffany Welsh, who leads design; the company holds an active Massachusetts home improvement contractor registration and describes itself as a boutique firm specializing in custom homes, kitchen and bathroom renovations, additions, and basement work across Cape Cod. The reviews are almost entirely built around Ben's hands-on craftsmanship across a wide range of projects. A July 2025 review described a primary bathroom repair and remodel after a customer's realtor specifically recommended the couple. An August 2025 review described a home addition and remodel completed on time and on budget, with Ben described as thorough and meticulous when unexpected issues came up. Other reviews describe a full upstairs bathroom and basement conversion into an entertainment area with a game room and bar in 2022, kitchen renovations and new windows and decks over what one reviewer called several projects together, 24 new window installations, a new deck build, and a siding repair job. One customer described BMW transforming a long-neglected newly purchased home "into an oasis," praising both the Welshes and their subcontractors as punctual and flexible through frequent add-ons. Several reviewers describe repeat business spanning years — one said BMW had done several renovations in their home over four years "with outstanding results." The company's own website gives two different answers about how long it's been in business — the About page says over 15 years, the homepage says over 25 — so that's worth a direct question if longevity matters to you. Every one of the fifteen written reviews on file, running from 2021 through 2025, is five stars, and Google shows the same perfect rating from 19 ratings. There's no complaint anywhere in that history. For anything from a single bathroom to a full addition, this is a small, hands-on team with a long, consistent track record behind it.
