Koski Janitorial is a cleaning business that was started by a husband and wife team who was determined to build a business that has integrity and provides hard and thorough work. We worked very long hours every day of the week in order to get where we are today. This foundation has helped us to build a business that is founded on dedication to each and every job that we complete!

Our mantra to always to the best job possible has allowed us to build great and longstanding relationships with all of our clients. Since our beginning, we’ve grown quickly as a business, yet we always strive to treat each cleaning job like it’s our only job!
