How It All Started
Over two decades ago, Jason was working at Stockton Honda when a life-changing opportunity came his way. A longtime family friend—who owned a successful window washing business in the Bay Area—offered to pass it down. Jason had worked for him as a teenager, learning the trade and developing a passion for quality workmanship. When the friend was ready to retire, he entrusted Jason with the business and all its trade secrets.
With Brenda’s support and four little ones at home, Jason stepped out in faith and launched Casper’s Window Washing Services. It was a leap into the unknown, but he knew that with hard work, integrity, and trust in God, he could build something lasting. And he did.
Meet Our Founders
Casper’s Window Washing Services is built on a foundation of family, faith, and hard work. Jason and Brenda Casper have been married for over 25 years and are proud parents of four. Jason, a Fremont native, and Brenda, born and raised in Stockton, have made it their mission to serve their community with honesty, reliability, and care. Together, they’ve created a business that not only supports their own family but gives back to others through church, community service, and the values they live by every day.
