Our Story – Chan Drainage

I began working in crawl spaces back in 2006, installing vapor barriers and interior drainage systems. From day one, I developed a passion for solving tough problems and doing the kind of hands-on work most people avoid. That dedication to hard work is what inspired me to earn my contractor’s license, build a skilled and dependable crew, and launch Chan Drainage — a company committed to doing the job right the first time.

At Chan Drainage, we specialize in comprehensive crawl space and drainage services throughout Marin County, Sonoma County, San Francisco, and the greater Bay Area. Our services include sump pump installation, crawl space encapsulation, vapor barrier systems, crawl space insulation, epoxy floor coatings, French drains, interior drainage systems, garage clean-outs, irrigation solutions, and the installation of durable synthetic moisture control products.
Whether you're dealing with excess moisture, standing water, or foundation issues, we’re here to help. If you’ve got a drainage problem, Chan Drainage has your solution.
