Biviano General Contracting LLC works out of 2183 Ocean St in Marshfield and is hired for whole-house work on the South Shore — custom modular homes, decks, additions, kitchens and baths, accessory dwelling units, and coastal house elevations. The company says the Biviano family has been part of Marshfield's building and real estate community since the 1960s and that it has been building and renovating homes for over 40 years, and it describes itself as family-owned, run today by Michael Biviano Jr., who worked alongside his father.
What homeowners write about most is speed paired with finish quality. One Marshfield-area homeowner described a 520 sq ft wooden deck that other companies would not even return calls about: the crew demolished it on 10/31, framed it, and finished on 11/6. Another said a deck that had become a safety hazard was redesigned with updated materials after the owner came out to look at it himself. Others describe a back deck rebuilt with a roof, heaters and motorized screens, and a beach house that was raised.
The modular-home side draws the same comments. Two homeowners reported new builds finished on time and within budget, one moving in nine weeks to the day from the first design meeting; a Humarock homeowner said the house was completed ten and a half weeks after it was set on piling. Kitchen and bath renovations come up repeatedly, including a full kitchen and dining area, and a rebuild after major water damage covering tile, wood floors, custom woodwork, painting, plumbing and electrical.
Michael Biviano is named personally in most of these accounts — managing crews, coordinating permits, inspections and subcontractors, and staying reachable. One homeowner 3,000 miles away said he kept both her and her father in Marshfield informed while the laundry was moved from the basement to a second-floor bedroom in under two weeks. A 2025 reviewer said the company held the licensing needed to finish a deck near conservation land after a previous contractor could not.
The record is uniformly positive: 30 reviews on file from 2023 to 2026 across three sources, with a 5.0 Google average from 33 ratings and no negative comments. Two things are worth clarifying up front. The 40-year tenure is the company's own statement, while the reviews on file begin in 2023. And one 2026 review credits the build to "Biviano Modular Builders" rather than the LLC named here, so it is worth confirming which entity signs your contract. For a South Shore homeowner planning a deck, a kitchen, an addition, a modular build or a coastal elevation, ask for a written scope covering plans, permits and engineering, and for references on a project the size of yours.
