About Us

Carpet Cleaning

Donley Building Services was started in 1990 by Mike and Sandy Donley. Since that time each of their five children have had a hand in helping grow this christian based buisness.

Since moving to O’Fallon, Missouri in 1997, Donley Building Services has expanded service to include all of St. Louis County, St. Charles County, Warren County, and Lincoln County. In the last few years, our janitorial service has grown by 15% because of our highly trained and committed staff, dedicated and devoted leadership, and our concentration on customer service. The success of this focus on client satisfaction is evidenced by our high percentage of repeat customers. Any building cleaned by Donley Building Services will be a safer, happier, healthier, and more productive work place.

Donley Building Services floor care service has tripled in size in order to meet customer demand. Keeping a building's floor surface, whether its resilient flooring, natural stone, ceramic, or carpet, is vital to any manager maintaining the integrity and life of a facility. By tailoring services based on our 20+ years of experience in the industry to the over 20 million square feet of commercial space we service, we are continuously able to exceed customer expectations.
