For over 103 years, USSI has continued to fill the vacuum in contract cleaning.
The story of USSI is the story of every American dream. In 1912, Charles Herschel, a European immigrant, founded the United States Window Cleaning Company. Today, USSI is a full-service janitorial company cleaning over 30 million square feet across 600 locations each day.
As one of the largest privately-held cleaning contractors in the region, USSI continues its tradition of delivering superior customer service in every building, every day.
