SL UNITED CONSTRUCTION, INC.

SL UNITED CONSTRUCTION, INC. specializes in precision glass and glazing systems for mission-critical federal facilities, with demonstrated expertise in window replacement, sealing, and high-performance envelope retrofits. The contractor delivers turnkey glazing solutions for institutional and defense infrastructure, including custom fabrication, thermal break installation, and weatherproofing of multi-pane, impact-resistant glazing systems. Their technical proficiency extends to structural glazing, gasketed curtain wall integration, and compliance with ASTM E330 and E331 standards for air and water infiltration resistance. A key differentiator is their ability to execute sensitive, occupied-space renovations with minimal operational disruption—particularly in secure government environments requiring strict safety, security, and continuity protocols. The company has performed work for the Department of Defense, specifically on facility upgrades at military administrative and support buildings, including resource management offices, visitor centers, maintenance facilities, and garages. This reflects a focused engagement with DoD’s installation modernization initiatives, where glazing replacements enhance energy efficiency, occupant safety, and facility resilience. Their relationship with the DoD suggests alignment with Base Realignment and Closure (BRAC) and Energy Savings Performance Contract (ESPC) priorities, particularly in upgrading aging building envelopes. SL UNITED CONSTRUCTION, INC. operates primarily within NAICS 238150, focusing on specialized glazing systems for public infrastructure rather than residential or commercial new construction. Their market positioning centers on government and defense-sector facility upgrades, where durability, code compliance, and phased construction sequencing are critical. The firm does not broadly engage in general construction but instead targets high-skill glazing applications requiring precision installation and adherence to federal building standards. As a Women-Owned Small Business and Woman-Owned Business certified contractor based in El Cajon, California, SL UNITED CONSTRUCTION, INC. leverages its small business status to compete for set-aside opportunities within federal procurement frameworks. The company maintains a regional footprint in Southern California with the capacity to mobilize across defense and federal facility networks, positioning itself as a trusted niche provider for mission-critical building envelope rehabilitation.
