Founding owners, husband and wife team Bill and Kathleen, started as ordinary customers, looking to upgrade their own home with replacement windows and replacement patio doors. Seeking an energy-saving window and door solution, they found a series of poor contractors and a need for an improved service that customers can rely on. Bill and Kathleen felt that they could do it better – and they have been revolutionizing the home improvement industry one customer at a time for 20 years. American Vision Window is now the number one window replacement company in California and Arizona, and service areas include Ventura County, Los Angeles County, Orange County, San Diego County, Greater San Jose Area, and Arizona.
