Bay Area Siding & Window Contractor

Bay Area Siding Company is a Larkspur-based contractor specializing in the exterior of your home — siding and windows — across the San Francisco Bay Area. We treat every project as a wall system, not a cosmetic cover-up: what keeps weather out, what holds up to fog, sun, and fire exposure, and what still looks right in ten years. If you’re comparing contractors, start here, then dig into the specific service you need.

What we do

We install and replace siding and windows for homeowners, and we handle multifamily and commercial exteriors. These are the areas most homeowners come to us for:

Siding replacement & installation — the full tear-off-and-re-side decision, and how to choose a material
James Hardie fiber cement, LP SmartSide, fiber cement, vinyl, and wood siding
Window replacement — Anlin, Milgard, Andersen, Marvin, and Pella
Multifamily & commercial exteriors — large-scale, tenant-occupied projects

Why homeowners choose us

The value in a re-side isn’t the new color — it’s what happens behind it. When we tear off old siding, we take it to the sheathing and inspect the water-resistive barrier and flashing, correcting problems before the new cladding goes on, and we install to manufacturer specification so product warranties stay valid. You get a clear written scope up front and one project manager from the first walk of the house through the final walkthrough. If a lower-cost material is the right call for your project, we’ll tell you.

Built for Bay Area conditions

Coastal fog and salt air, inland heat and UV, seismic movement, and wildfire-hazard zones each put different demands on an exterior. We match materials and details to your specific microclimate and confirm fire-zone and permit requirements with your local building department before we start — accurate guidance, not one-size-fits-all promises.

How your project goes

Estimate & walkthrough. We walk the house, talk through materials and goals, and give you a clear written scope.
Planning & permits. We confirm any fire-zone or permit requirements with your local building department before work starts.
Tear-off & inspection. We remove the old cladding down to the sheathing and inspect the water-resistive barrier and flashing.
Corrections. We repair any damaged sheathing, barrier, or flashing before the new material goes on.
Installation to spec. Your siding or windows are installed to manufacturer specification, which keeps product warranties valid.
Final walkthrough. We review the finished work with you and make sure it’s right.
