About Our Commercial Cleaning Company

The Story of Jack’s

Jack Schmitzer started his one-man cleaning and maintenance company in 1952; today there are more than 400 eager professionals and we’re proud to say we’re one of the leading commercial cleaning companies in Northeast Wisconsin. Jack would be proud!

Today, Lauri Struck, Jack’s daughter, runs the company with a real hands-on, the-buck-stops-here attitude, and she’s very active in day-to-day operations. She has the same skill in hiring good people, and the same high expectations of their work.

We provide cleaning and maintenance services every day of the week, 24 hours a day, in order to meet the demands of our customers. (Actually, we make it a point not to stop there. We get a lot of gratification by exceeding customers’ expectations!)


Jack’s stays on top of what’s happening in the professional cleaning industry and the Northeast Wisconsin communities. We’re active members of these organizations:
