NAICS 321911 – Wood Window and Door Manufacturing covers the production of interior and exterior wood windows, doors, and related millwork components designed for commercial, institutional, and residential applications. This sector includes the fabrication of solid wood, engineered wood, and composite wood products such as hinged, sliding, and specialty doors; single- and multi-pane windows with wood frames; and custom millwork assemblies used in building envelope systems. In government contracting, these products are essential for renovation, new construction, and historic preservation projects across federal facilities, including courthouses, military barracks, VA medical centers, and national park infrastructure. Demand is driven by compliance with energy efficiency standards, architectural specifications, and sustainability requirements for federally funded buildings. No contractor data is available to identify top performers in this NAICS code within the government contracting space. The competitive landscape likely includes a mix of small businesses specializing in custom millwork, regional manufacturers with federal certifications, and larger firms with diversified building product portfolios. Many contractors in this space operate under small business set-asides due to the specialized, labor-intensive nature of wood window and door fabrication. No agency data is available to identify primary buyers in this sector. However, procurement activity is typically tied to the General Services Administration, Department of Defense, Department of Veterans Affairs, and the National Park Service, particularly for projects involving facility modernization, historic restoration, or new construction under the Unified Facilities Criteria. The market is characterized by fragmented competition with high barriers to entry due to material sourcing, quality control, and compliance with ASTM and ANSI standards for weather resistance and structural performance. Opportunities exist for contractors with expertise in custom fabrication, LEED-aligned materials, and experience delivering to federal architectural specifications. Demand remains steady in preservation-focused projects and energy-efficient retrofits, with growing emphasis on sustainable wood sourcing and low-VOC finishes.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 321911 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
