Fox Valley's Choice for Commercial Cleaning Companies

Our slogan says it all: “Whatever It Takes – Every Day Since 1952.” We do what it takes to get the job done right, and we’ve been doing it that way since Jack Schmitzer started the business in 1952.

Since that time, we’ve grown to become a leader in Northeast Wisconsin, providing commercial cleaning services throughout the area. Our team of more than 400 trained professionals work around the clock at facilities large (in fact, very large!) and small, on contract or one-time basis. There’s nothing we can’t handle, and handle with unparalleled skill.

As a commercial janitorial company, we are your single-source solution for commercial janitorial and facility maintenance services. We serve all different types of industries, each with unique parameters, needs, setups and demands:

  • Commercial
  • Industrial
  • Retail
  • School/Education
  • New Construction
  • Medical Facility

We’re proud to be serving the Fox Valley – including Appleton, Green Bay, Kaukauna, Neenah, Menasha and Oshkosh – and other areas throughout Northeast Wisconsin.
