Servicing Marshfield, Duxbury, Scituate & the South Shore
Watch Our Work
Real Biviano jobs across the South Shore — modular homes set in a single morning, decks, and finished interiors. No stock footage. This is the crew that shows up.
The 4-Hour Set
"11:15am, all done." Foundation in the ground, then the crane sets the modules and the house is weather-tight the same day. One family handles all of it — permits, engineering, demo, and the build — start to finish.

"I have talked to people who absolutely highly recommend this Company. Excellent, professional service."
Why Biviano GC
The Biviano family has been building homes on the South Shore since the 1960s. Owner Michael Biviano Jr. learned the trade from his father — every lesson rooted in respect, fairness, honesty, quality, and pride. Today, those same values guide every project we take on.
Our Family. Your Home.
Most contractors hand you off — to a separate engineer, a permit expediter, three subs, and a project manager who eventually stops calling back. We don't. Biviano is one Marshfield family that keeps your whole project in-house: plans, permits, engineering, demo, and construction. You make one call. We handle the rest — and we stand behind it long after the job's done.

What Homeowners Say
"We tried to get our deck replaced but no company would call us back. Then we went to Biviano General Contracting and they immediately responded and gave us a low-stress, no-hassle estimate to replace our 520 sq ft deck. Michael Biviano was extremely professional and a pleasure to work with. We asked if they could have it installed by Thanksgiving and they did. The crew was awesome. They started 10/31, demolished the deck in a few hours, framed it out, and finished on 11/6. Never seen a crew work so hard. We were so pleased that we're already planning our next project; residing our house. I would proudly recommend them."
"Mike and his crew did a great job expanding and remodeling our kitchen. We love our new space! Easy to communicate with and very responsive to all our questions. We highly recommend and will definitely use them for future projects!"
"For the past 2 years we have enjoyed our new kitchen and dining area that Biviano General Contracting LLC made a reality. Through design and build Mike and team were great partners. Highly recommend."
"Building our new house in Humarock with Mike Biviano was a happily ever after journey. From start to finish Mike was very professional. Always available to answer questions, go over thoughts and ideas. Mike builds a high quality home with attention to detail. Once the house was placed on piling it was completed 10 and a half weeks later and we moved into our new dream home."
"Mike came by on short notice to check out a concerning crack in my ceiling. He was responsive, knowledgeable, and kind — exactly what you want in a contractor. Whole heartedly recommend!"
"Mike and his crew were great to work. We had our entire back deck redone, added a roof, heaters, and motorized screens. It looks amazing. Mike was responsive, honest, and it felt like he always had our best interest in mind when sharing ideas and weighing the pros and cons. We'd highly recommend this group."
