Services
Cleanroom Services
Our cleanroom specialists maintain ISO 9001-certified sterile environments through micro-cleaning, sterilization, and contamination control. Using advanced H2O2 fogging technology and Halo Disinfection Systems, we achieve 99.9999% microbial elimination. Our GMP-certified technicians follow strict protocols for pharmaceutical facilities, laboratories, and controlled manufacturing environments.
Data Center Cleaning
Specialized cleaning for data centers prevents equipment failure through subfloor sealing, anti-static floor care, and HEPA-filtered vacuuming. Our technicians use non-conductive cleaning agents and follow strict safety protocols to maintain operational integrity while eliminating dust and contaminants that cause overheating.
Hydrogen Peroxide Fogging
Our H2O2 fogging services use aerosolized hydrogen peroxide to eliminate viruses, bacteria, and pathogens at the molecular level. This method safely sterilizes sensitive environments including healthcare facilities and laboratories, reaching 99.9999% effectiveness against C. difficile spores while being safe for electronics and building materials.
Day Porter Services
Skilled day porters maintain facility appearance through restroom sanitation, trash removal, and high-touch surface disinfection. Our team provides event support and supply management while maintaining non-disruptive cleaning schedules for corporate offices, healthcare facilities, and industrial sites.
