Early History

Sun Boss Corporation is the oldest patio construction company in Southern California. John Kain founded the company and started the company based on building a better product to provide solar protection to the exterior of local homes here in Southern California. Over the past six decades, Sun Boss has been developing solar protective products that ultimately provide a great deal of shade, protection and unique outdoor and indoor living areas.

Products that often qualify for federal tax credits by making your home a more efficient and comfortable place to live.

From the most basic solar powered attic ventilation system, to the most extravagant third story home addition built to bring in the sunset views, yet allow year round comfortable living. Sun Boss has worked vigorously to make your home the most efficient and comfortable home it can be.

The last six years he has managed not only the local jobs but also our installation crews. Every one of our installers are professionally trained to specifically install our products.
