The Bay Area's most trusted window company.
Founded in 1989, Golden State Windows has spent more than three decades installing windows, siding, and doors across the San Francisco Bay Area — trusted by over 8,000+ homes.
From a single truck to the Bay Area's standard.
Our founder started installing windows on the San Francisco Peninsula in 1989. The promise was simple: do work he'd be proud to put his name on. More than three decades later, that same standard governs every project — whether it's a single sash on a Victorian or 60 openings on a new-construction estate.
We're 100% employee-led. Every measurement, every install, every warranty visit is handled by people on our payroll. That continuity is what allows us to back our work with a true lifetime warranty.
Three rules we don't bend.
Engineered, never assembled
Every install begins with measurement, modeling, and material selection. We earn the work by treating it as engineering, not handywork.
No subcontractors. Ever.
The crew that walks your home on day one is the crew that finishes it. Continuity is non-negotiable.
Transparent pricing
Fixed-price contracts. Itemized line-items. No change-order surprises after the deposit clears.
