The contractor delivers routine and specialized cleaning services for administrative, operational, and support facilities, including high-traffic public areas, technical offices, and alternate control centers. Their expertise includes the use of EPA-registered disinfectants, OSHA-compliant waste handling, and scheduled deep-cleaning protocols aligned with federal facility management guidelines.
