Who We Serve

Colliers International has utilized 21st Century Janitorial for more than ten years, during which time they have provided our properties(approximately 7000,000 SF) with excellent and efficient full-service janitorial cleaning. I highly recommend 21st Century Janitorial Services to handle your cleaning needs.

Kevin Huchingson

President and CEO of Colliers International

I have had 21st Century Janitorial Services INC for a while now in my building. I would recommend their services to anyone who ask about them. They are on top of every detail within the cleaning. 21st Century is by far the best cleaning company we’ve had.
