DJB CONTRACTING INC

DJB Contracting Inc. specializes in roofing systems, building envelope maintenance, and selective commercial construction for mission-critical federal and institutional facilities. Their technical expertise centers on the inspection, repair, and preventive maintenance of complex roof assemblies, flashing systems, gutters, drains, and skylights, with a demonstrated focus on historic and high-value structures. The contractor delivers precision work on building envelopes, ensuring watertight integrity and long-term durability through material-specific remediation, sealant application, and weatherproofing techniques tailored to legacy infrastructure. Their ability to execute sensitive, low-disruption repairs in occupied, protected environments—such as Smithsonian research facilities—highlights a strong command of site-sensitive construction protocols and heritage preservation standards. The company maintains a consistent relationship with the Smithsonian Institution, where they perform specialized roofing and envelope repairs on culturally significant buildings, including preventive maintenance programs for historic structures. They also deliver similar services for the General Services Administration, undertaking both targeted roofing studies and interior modernization projects within federal properties. This recurring engagement suggests a trusted, mission-critical role in sustaining federal asset integrity through proactive, non-invasive interventions. DJB Contracting primarily operates under NAICS 238160 (Roofing Contractors), positioning them as a niche provider of high-performance building envelope solutions rather than general construction. Their work aligns with institutional and federal sectors requiring technical precision over scale, emphasizing durability, code compliance, and minimal operational disruption. They are not engaged in new-build commercial construction but focus on the lifecycle management of existing infrastructure. As a small business structured as a 2L entity based in Upper Marlboro, Maryland, DJB Contracting operates regionally within the federal government’s Mid-Atlantic market. While they hold no formal government certifications, their consistent performance on sensitive federal projects demonstrates reliability, technical competence, and an understanding of federal facility standards and procurement workflows.
