What Abacus Builders and General Contractor does
Abacus Builders and General Contractor is a privately held residential general contractor founded in 2001 and headquartered at 190 Old Colony Avenue in Boston, Massachusetts. The firm specializes in ground-up new construction, full gut remodels, insurance restorations following fire or flood damage, roof deck and porch construction, design build services, and exterior envelope solutions, roofing, siding, and masonry work. Its core geographic market is explicitly restricted to the Boston Metro and MetroWest areas, where it has completed over 2,300 projects across roughly 24-25 years of operation, including multi-unit luxury condominium developments in South Boston, Everett, and Quincy.
The company serves two primary customer segments: residential property owners and developers seeking new construction, renovation, or restoration services (primary), and insurance companies and property managers requiring trusted contractors for post-loss restoration (secondary). Projects are priced through custom fixed-price quotes, with average build costs referenced at approximately $250 per square foot for certain developments. Revenue is earned through one-time project contracts rather than recurring licenses or subscriptions, and the sales motion is consultative, relying on direct website inquiries, phone calls, Google reviews, and platforms such as Angie's List and Houzz for lead generation.
Abacus operates without proprietary technology platforms, leveraging long-term partnerships with Boston-area architects (Context Architects), engineers (CEC Engineers), and material suppliers (Pella Windows, James Hardie, Trex, GAF Roofing) to deliver projects. The firm is owner-led by Nick Cary, supported by a small management team including an office manager, project manager, and additional crew members. There are no disclosed funding rounds, indicating bootstrapped organic growth. Marketing emphasizes a multi-channel digital presence including YouTube construction timelapses, Instagram, TikTok, LinkedIn, and Facebook, alongside active community engagement with South Boston organizations such as ONEin3, Notre Dame Education Center, and the South Boston Collaborative Center.
