Our Story

A1 Window Cleaning was started by 6th generation Nevadan, Ian Callahan. As a new college student at the age of 19, Ian was having trouble finding a job that would work with his school schedule. With the last $100 in his wallet, he bought some window cleaning gear, learned how to clean, and hit the streets. Within a year’s time, his business turned into a full time business venture. After finishing school, Ian loved being an entrepreneur and decided to keep developing and expanding the company. In 2013, Ian’s father Mike ended a 22 year long career at IGT and joined Ian as a business partner. Ian and Mike decided to change the company name from CalFlex Window Cleaning LLC and started Callahan Enterprises LLC that is the parent company to A1 Window Cleaning. A1 Window Cleaning is still the same owners and crew, just a new name.Finally, A1 Window Cleaning/Spifco has entered into a work agreement with Mitch Bergstrom and A1 Window Cleaning. A1 Window Cleaning is now the Trusted and Exclusive window cleaning provider for A1 Window Cleaning and Spifco.
