Fast COVID Disinfecting & Sanitizing Services

Ensure your medical office, manufacturing facility, warehouse, restaurant, or other commercial space is COVID-free.

The team at our cleaning agency uses electrostatic foggers from Clorox and Victory to disinfect every surface in your facility. Additional hand-wiping by our PPE-equipped cleaners further sanitizes high-touchpoint areas like phones, doorknobs, and shared surfaces.

Our sanitation methods are CDC and EPA-approved for your safety and peace-of-mind.

FREE facility surveys available! Call our cleaning company at (503) 691-0776 today.

They are available at any time with any concerns, and I’ve never had any. I would highly recommend their commercial janitorial services.
