Your Local Seamless Gutter Installation Experts

Superior Seamless Gutter is a locally owned and operated gutter installer based in the Northern California Bay Area. Our service areas include Sonoma, Napa, and Marin Counties.

Owner Greg Van Cleave has been in the gutter installation industry for over 30 years. He started working for a local sheet metal company specializing in seamless gutters. After gaining a requisite level of industry experience, Greg took the knowledge he’d acquired and struck out on his own, founding Superior Seamless Gutter in 1986.

In the following years, Greg became established with several select roofing and building contractors in the North Bay Area. These contractors came to value Superior Seamless Gutter’s quality workmanship, quick response times, and reliability.

Seamless Gutter has continued to stay on the cutting edge of the gutter installation business. For example, we developed a unique seamless gutter installation technique that is now an industry trademark, frequently imitated by other companies.

As a customer service-based company, Superior Seamless Gutter takes pride in every job, whether a small residential home or a large hilltop mansion. We use only the best available materials. To top it off, we offer an unmatched guarantee – a lifetime warranty on every seamless gutter system we install! So, if you want only the best in gutter, downspout, and leaf guard installation, you’ve come to the right place!
