Manganaro Midatlantic

What Manganaro Midatlantic does

Manganaro Midatlantic, LLC is a regional specialty trade subcontractor and wholly-owned subsidiary of Manganaro Building Group, LLC, an employee-owned (ESOP) commercial construction firm founded in 1958 and headquartered in Beltsville, Maryland. The firm delivers drywall, masonry, acoustical ceilings, doors/frames/hardware (Division 8), Division 10 specialties, and painting/wall covering/coating services on commercial construction projects, working directly for general contractors and project owners across the Mid-Atlantic region (with sibling entities covering the Northeast, Southeast, Florida, Georgia, and Tennessee, and affiliates CAGE Building Group and Prehung Doors, LLC extending reach into Tennessee drywall and Maine door manufacturing). Its technology stack is conventional construction-trade execution: conventional scaffolding, swing stages, hydro-mobile platforms, and structured pre-construction through close-out project management, with no proprietary software product disclosed.

Manganaro Midatlantic generates revenue through project-based subcontracts awarded largely via competitive bidding against general contractors such as Clark Construction, Hourigan, Branch Builds, and Barnhill Contracting. Pricing is determined by scope, materials, and labor estimates per project rather than published rate cards, making revenue lump-sum and episodic in nature. The customer base spans healthcare facilities (Maine Medical Center, UMMC Stoler Center, Inova Women's Center, Carilion Franklin Memorial), higher education institutions (UVA Darden, MassBay Community College, UNC Kenan-Flagler), federal and local government (Charles R. Jonas U.S. Courthouse, Richmond International Airport, Ronald Reagan Airport), and commercial/hospitality projects. Multiple service lines are typically bundled into single-source contracts per project, reducing coordination overhead for general contractors and supporting repeat-bid relationships.

Its go-to-market is relationship-driven enterprise field sales executed by regional business development managers and presidents, with the firm's 65-year brand, ABC STEP Platinum safety recognition (six consecutive years), and dense regional craftsmanship awards serving as primary commercial signaling. The company also operates Manganaro Academy as an internal training pipeline and has integrated vertically via the 2022 acquisition of Prehung Doors, LLC to internalize door manufacturing for multi-family residential and commercial jobs. Financial scale is not publicly disclosed; the firm is a privately held LLC under ESOP ownership with no outside equity backing identified.
