About Bay Area Siding Company

Bay Area Siding Company is a Larkspur-based siding and window contractor serving homeowners across Marin and the greater San Francisco Bay Area. We focus on one thing — the exterior envelope of your home — and we treat it as a wall system, not just a new skin: what keeps water out, what holds up to fog, sun, and fire exposure, and what still looks right in ten years.

Who We Are

We’re a locally owned exterior-renovation company based in Larkspur, Marin County. Our work centers on siding installation and replacement, window replacement, and larger multifamily and commercial exterior projects across Northern California. Because we specialize rather than generalize, the crew that quotes your project is fluent in the details that actually determine how a re-side performs — flashing and water-resistive barrier integration, correct fastening and clearances, and how each material behaves in a specific Bay Area microclimate.

What We Install

Siding. We install James Hardie fiber cement (including the HZ10 line formulated for California), other fiber cement, LP SmartSide engineered wood, natural wood, T1-11, vinyl and insulated vinyl (including CertainTeed lines), and aluminum and mobile-home siding. When you’re weighing options, we’ll tell you honestly where a lower-cost material is the right call and where it isn’t.

Windows. We install Anlin, Milgard, Andersen, Marvin, and Pella, plus aluminum replacements — retrofit or full-frame depending on your openings and goals.

Multifamily & commercial. We handle large-scale re-siding and window replacement for apartment owners, HOAs, and property managers, with phased scheduling that keeps occupied buildings livable during the work.

How We Work

Every project starts with a walk of the house and a clear, written scope — what’s being removed, what we expect to find behind the old cladding, and how the new system goes on. On a re-side, tear-off exposes the sheathing and the water-resistive barrier and flashing so we can inspect and correct problems before new siding covers them. We install to manufacturer specification, which is also what keeps product warranties intact — for example, James Hardie’s transferable substrate limited warranty and its ColorPlus finish warranty when installed to spec.

Serving the Bay Area

From Marin and the North Bay through the East Bay, Peninsula, and South Bay, we bring the same standard to every job. If you’re planning a siding or window project, we’d be glad to take a look and give you a straightforward estimate.
