Master Cleaning Services

 Performance that Delivers Peace of Mind 

Responsive, reliable, & flexible master cleaning services for your facilities.  

Reliability Comes Standard

Anyone can clean a floor or take out the trash. It is how we do it—day in, day out—that separates us from the rest. Our care is the difference between a place that simply looks clean and a space that feels amazing.

Details Drive

Consistent attention to detail matters: the disinfection of handrails, the dusting of blinds, the cleaning of upholstery, the polishing of floors . . . the details are important to us because they are important to you.

About Us

Since 1993, we have embraced a philosophy of relationship building rather than a focus on servicing a “winning bid.” It is about achieving excellence every day. That is how we hold up our end of the bargain, and that is how we have built lasting relationships with our customers from day one.

Founded in Denver, Colorado in 1993 as Kleen-Tech Building Services, the company quickly established itself as a trusted janitorial services provider. Over the years, we have developed and refined numerous systems, processes, and tools that enable us to continuously improve and better serve our customers. In 2019, Kleen-Tech underwent  a change of ownership and organizational structure.


Under the newly formed Kleen-Tech, all of the organization’s defining systems, processes, tools, and culture, along with its first-class leadership remain in place. We are proud to service customers located throughout the United States with over 1,000 employees providing the Kleen-Tech brand of service to more than 20 million square feet of commercial and government facilities.

Pencil in Hand

“Kleen-Tech’s focus on continuous improvement and enhanced efficiency creates true partnerships. When we came under economic pressure, Kleen-Tech worked with us to revise custodial services to meet our specific needs and budget.”
