Southcoast Building is a two-person outfit out of Assonet — builder Roy Cabral and business manager Mike Bicho — that takes on a limited slate of new custom homes, ADUs and major additions each year, with projects the company says start around $200,000. Cabral brings 39 years on job sites, Bicho 35 years in business and finance; together they say they've built or put under contract more than $9 million in homes and additions since starting the company in Westport in 2020. Twenty Google reviews spanning 2022 to mid-2026 run five stars straight through, and the same pattern repeats across that span: Mike answering the phone and returning calls promptly, Roy running a tight crew. Reviewers from those years described full custom-home builds — customizing layouts and finishes with Roy walking them through progress on-site, a complete gut renovation plus a 3-bedroom addition that stayed on budget and schedule — alongside a recurring, more specific thread of window and door work: a 16-window-and-front-door job, a 4-unit investment property's full window replacement that came in under two competing bids, and an MBTA Rail project window swap. On the roofing side, customers described same-day roof replacements — one done ahead of a solar install, one for a business needing a new roof and exterior doors on short notice — with cleanup mentioned almost every time. A 2022 review noted Southcoast accommodated an FHA 203K renovation loan without friction. The company's Massachusetts Home Improvement Contractor registration (203047) is active in the state registry, and the Better Business Bureau gives it an A+ rating. BBB's own profile also lists a Massachusetts Construction Supervisor license and a Rhode Island contractor's registration, plus a founding date of April 2020 as an LLC with Michael Bicho as owner — details the company echoes on its own site, along with a stated service area running from Westport and Dartmouth down through New Bedford and Fall River. Anyone reaching out should ask about current scheduling given the company's stated small-batch approach — Southcoast says it deliberately limits how many builds it takes on each year.
We had a great experience working with Mike and Roy throughout the construction of our home. Even though the home was already planned when we purchased it, they made the process of customizing the layout and choosing finishes easy and enjoyable. Roy was always happy to walk us through the progress whenever we stopped by, and both he and Mike took the time to answer our questions and keep us informed throughout the build. They were knowledgeable, easy to work with, and genuinely cared about making sure everything was done right. We're very happy with our new home and would definitely recommend Southcoast Building to anyone looking for a quality new construction home.
We cannot say enough good things about Mike and Roy with Southcoast Building. From start to finish, they were absolutely amazing. We met with a few contractors, but after our first sit-down with Mike and Roy, we knew they would be the team we wanted to work with. They stuck to the agreed-upon timeline, stayed on budget, and their communication was seamless throughout the entire project. They were incredibly transparent and trustworthy. Our project was a complete gut of our existing house and a 3-bedroom, 2-bathroom addition with a brand new kitchen. The workmanship was outstanding, and every crew and subcontractor they brought in did amazing work. If Mike or Roy ever noticed a potential issue or improvement on the blueprints, they took the time to sit down with us and walk through practical, well-thought-out solutions together before moving forward. As a young couple who had never built before, I was expecting the process to be overwhelming, but they made everything feel smooth and manageable. They took the time to explain things, answered every question, and truly had our best interests in mind. We felt confident and supported every step of the way. We would highly recommend them to anyone looking for honest, reliable, and high-quality builders. We are excited for the many years to come in the home Southcoast built for us.
I had a great experience working with Mike and Roy from start to finish. Roy and his crew came and did a great job. They were conscientious and professional. They didn’t just plop the windows in place but they corrected and replaced any imperfections be it rotting wood to leveling out prior window defects. They would definitely be on my call list for any other renovations needed. Not only did they install the windows but painted the trim and walls if there was any chipping. Roy even repaired a flapping siding strip we had on the side of the house without knowing how we would repair it. He did it without us asking and it was much appreciated. They put in full days, cleaned as they went. If anyone has renovations to be done, don’t hesitate in calling them.
Great experience! Competitive quote, timely scheduling, and professional workmanship. We couldn’t be happier with our 16 new windows and new front door.
Southcoast Building LLC, did an excellent job installing my windows. They are very professional.
