DASTIA-SIIVOUS OY

DASTIA-SIIVOUS OY provides professional janitorial and facility cleaning services to U.S. government installations, with demonstrated experience supporting diplomatic missions under the Department of State. The contractor delivers comprehensive custodial operations including surface disinfection, waste management, restroom sanitation, floor care, and high-touch area decontamination in accordance with federal hygiene and safety standards. Their technical expertise lies in scalable cleaning protocols compliant with OSHA and CDC guidelines, use of EPA-registered disinfectants, and adherence to federal facility maintenance benchmarks. Specialization in secure environment cleaning—particularly in sensitive diplomatic settings—suggests familiarity with access-controlled facilities, biohazard protocols, and strict operational timelines. The contractor’s primary agency relationship is with the Department of State, where they deliver mission-critical cleaning services to maintain sanitary and secure conditions at overseas and domestic diplomatic facilities. This indicates an established capacity to operate under stringent security protocols, coordinate with federal facility managers, and comply with international operational requirements. DASTIA-SIIVOUS OY’s market focus is narrowly aligned with NAICS 561720, which encompasses commercial and institutional janitorial services. Their positioning is that of a specialized facility services provider focused on government-contracted custodial work, particularly in high-security or mission-sensitive environments. They do not appear to diversify into broader facility management or maintenance sectors. The entity is structured as a 2K firm based in Vantaa, Finland, with no publicly listed government certifications. While its physical headquarters are outside the United States, its contract activity confirms active participation in the U.S. federal procurement market for cleaning services, suggesting a cross-border operational model supporting U.S. government overseas missions.
