Owner Greg Van Cleave has more than 30 years of experience in the seamless gutter industry. Prior to establishing his own business, he worked for a sheet metal company for many years. Today, Mr. Van Cleave works alongside his son, estimator Cory Thomas, who says Superior Seamless Gutter has perfected the rain gutter installation process. “There’s really nothing we haven’t seen or addressed. We strive to find a solution for every problem we come across.”

Superior Seamless Gutter works with qualityminded contractors throughout the Bay Area. “Over the past 25 years, we’ve maintained positive working relationships due to our high level of professionalism, workmanship and quick response time,” says Mr. Van Cleave.

Company Philosophy

“We focus on providing the best for our clients, and our pursuit of excellence is evident in everything we do. We have high standards and are proud of the quality of our work. As such, we retain experienced installers who use their extensive training to perform clean, professional installations backed by lifetime warranties. Our estimator doesn’t work on commission—he was a lead foreman for many years, and he’s knowledgeable about the installation process and sensitive to the needs of our clients. Our office staff is available Monday through Friday (7am to 4pm) to offer support to our clients.”
