NAICS 238150: Glass and Glazing Contractors

NAICS 238150 – Glass and Glazing Contractors encompasses specialized construction services involving the installation, repair, and replacement of glass, windows, curtain walls, storefronts, skylights, and structural glazing systems in commercial, institutional, and federal facilities. This sector plays a critical role in building envelope integrity, energy efficiency, and aesthetic design, often requiring precision engineering, thermal performance compliance, and adherence to ASTM and ANSI standards. Contractors in this space typically work under prime construction contracts, subcontracting to general contractors or directly to federal agencies on renovation, new construction, and modernization projects. The work demands certified installers, advanced glazing techniques, and coordination with architectural and structural teams to meet stringent building code and security requirements. Top contractors in this sector include DAP Construction Management LLC, Elbow Grease Enterprises, LLC, AAECON General Contracting LLC, Sauve Construction LLC, Extreme Government Solutions LLC, and Kennedy Glass DMV, LLC. These firms range from small businesses with niche expertise in historic glazing restoration to mid-sized contractors with capabilities in large-scale curtain wall installations. The competitive landscape is characterized by specialized technical proficiency, local market presence, and demonstrated experience with federal building standards. Primary federal buyers include the General Services Administration, Department of the Interior, Department of Agriculture, Department of Veterans Affairs, and Department of Defense. Demand is driven by facility modernization programs, energy retrofit initiatives, security upgrades, and maintenance of legacy infrastructure, particularly at courthouses, VA medical centers, national parks, and military installations. The W071 Endist Kansas City contracting office also plays a notable role in regional procurement. The market offers consistent opportunity density due to the lifecycle-replacement nature of glazing systems and the growing emphasis on sustainable, high-performance building envelopes. Contractors with expertise in low-E glass, seismic glazing, blast-resistant systems, and LEED-compliant installations are well-positioned to compete, especially where local presence and small business status enhance eligibility for set-asides.
