Quackenbush Co

What Quackenbush Co does

Quackenbush Co., Inc. is a privately held general mechanical contractor founded in 1932 in Buffalo, New York, and continuously operated by four generations of the founding Quackenbush family. The firm delivers mechanical construction services including process piping (from 1/4-inch stainless tubing up to 36-60 inch pipe), HVAC installation and service, design-build, sheet metal fabrication, engineer-procure-construct delivery, and ongoing maintenance and emergency repair work for industrial, commercial, institutional, and government clients across the Northeastern United States.

The company operates a 40,000+ square foot ASME/NBI Code compliant fabrication facility at its 495 Kennedy Road headquarters, enabling off-site prefabrication of up to 90% of piping assemblies, skidded modules, and equipment modules before jobsite delivery. Its core technology stack includes BIM/Virtual Design Construction with CAD-based design verification and 3D laser scanning for jobsite layout and existing-conditions capture, supporting collision avoidance, schedule compression, and 100% x-ray tested welds. The firm holds ASME S-symbol and R-symbol certifications and maintains AWS Certified Weld Inspector credentials, qualifying it for boiler, pressure vessel, and nuclear work.

Quackenbush generates revenue through project-based professional services contracts awarded via competitive bidding and direct negotiation with owners, general contractors, and facility managers. Pricing is quote-based and project-specific with no publicly disclosed rates. The go-to-market motion is enterprise field sales, anchored by a deep project portfolio that includes Greenpac Mill (ongoing since July 2013), West Valley Nuclear Services Company, Buffalo Sewer Authority, FMC Corporation, Niagara Refining LLC, Erie County, University of Buffalo, and Burchfield Penney Art Center. Revenue streams span new construction, design-build, prefabrication services, and recurring maintenance and emergency repair work, with the 11-50 employee headcount and single Buffalo headquarters constraining the firm's addressable geography to the broader Northeastern region.
