- Serving all Sonoma, Napa, and Marin Counties
Since 1986, Superior Seamless Gutter has been built on hard work, integrity, and tradition. Founded by Greg Van Cleave, our promise has always been simple: deliver honest, highquality workmanship homeowners and contractors can trust across Sonoma, Napa, and Marin Counties.
Cory Thomas has been part of that mission since 1999, working alongside his father before taking ownership as the second generation. He continues to lead with the same dedication to craftsmanship, reliability, and attention to detail that define our name.
As a family owned company, we know gutters are about more than keeping water out, they are about protecting what matters most. That is why the North Bay trusts us for quality materials, quick response times, and a lifetime warranty on every system we install.
We are Superior Seamless Gutter, a legacy of quality, proudly protecting North Bay homes for generations.
Superior Seamless Gutters offers free estimates by knowledgeable estimators who do not work on commission. We are California-licensed gutter installation contractors. Our installers undergo years of extensive training to meet our standards in craftsmanship.
