Our Mission

At CFS Site Services, our mission is to protect the integrity, safety, and compliance of offices, laboratories, and critical environments through ISO 9001-certified facility services. We deliver reliable, scalable solutions including commercial janitorial services, day porter programs, handyman services, and utility technician staffing—customized to support the evolving needs of modern workplaces.

Our team specializes in GMP sanitization, critical cleaning, and contamination-controlled services for highly regulated environments, including cleanrooms, laboratories, data centers, pharmacy compounding rooms, manufacturing facilities, and vivariums. By integrating science-based cleaning methodologies, regulatory best practices, and continuous quality oversight, we help organizations maintain audit-ready facilities, reduce risk, and protect products, people, and processes.

CFS Site Services is trusted by life sciences, biotechnology, pharmaceutical, healthcare, and high-tech organizations seeking a single, ISO-certified facility services partner capable of supporting both routine janitorial operations and complex controlled environments.
