Rockridge Builders offers a wide range of design, engineering and construction services to residential, commercial and industrial clients throughout the East Bay. The scope of its projects runs from small kitchen and bathroom remodels to new custom homes and businesses. Competitive pricing and a fierce dedication to quality work and service has earned the company a growing base of satisfied customers who are quick to refer others, says owner Bill Hinkamp.

Mr. Hinkamp is a lifelong design/build enthusiast and a graduate of UC Berkeley’s College of Environmental Design. He founded Rockridge Builders in 1976 and says he’s since built a highly regarded reputation among local homeowners, architects and engineers. “We’ve completed more than 1,000 projects over the years, ranging from commercial tilt-ups to Victorian restorations to custom homes.”

Company Philosophy

“We believe there are three elements that go into a successful project. First, the project must be built to the highest possible standards. Second, the job must be successful as a value project for us and the client. Third, customers must refer us to their friends and associates in years to come. This won’t happen unless we make it our mission to achieve complete customer satisfaction on each job. We do this by providing superior communication, workmanship and attention to detail.”

Serving all of Contra Costa County including Concord, Richmond, Antioch, Walnut Creek, Pittsburg, San Ramon, Danville, Brentwood and Martinez.
