San Rafael Window Installation & Replacement

Windows built for how San Rafael actually lives

San Rafael is one of our closest markets. Our crews are based in Larkspur, minutes down the 101 from Terra Linda, Sun Valley, Gerstle Park, and the hillside neighborhoods above downtown. That proximity means shorter drives, tighter scheduling, and a team that already knows the housing stock here, from older downtown cottages to the mid-century Eichler tracts of Terra Linda. Bay Area Siding Company installs replacement windows across all of it.

The problems we replace windows to solve

Most homeowners call us because something has stopped working. Drafts around old sashes drive up heating bills. Failed insulating seals leave fog or condensation trapped between the panes, a sign the window has lost its gas fill and can't be repaired. Single-pane glass, still common in San Rafael's older and mid-century homes, radiates heat out in winter and lets it in during a warm inland afternoon. Windows painted shut or racked out of square won't open for ventilation or egress. And on shaded or north-facing walls, chronic moisture can rot wood frames and sills from the outside in. New windows fix the root cause instead of patching around it.

Choosing the right replacement windows

Energy performance. California's Title 24 energy code applies to replacement windows, so new units are dual-pane with a Low-E coating that reflects heat while keeping rooms bright. In the Bay Area's mild climate that combination cuts drafts and hot spots without making a home feel dark. We help you match glazing to each exposure rather than ordering one spec for the whole house.

Frame materials. Vinyl offers strong insulation value for the price; fiberglass and aluminum-clad wood add strength and a slimmer profile; wood-interior windows suit period and higher-end homes. For Terra Linda's Eichlers and other mid-century homes, we focus on preserving the clean sightlines and expansive glass that define the look while upgrading the thermal performance behind it.

Retrofit vs. new-construction. Retrofit (insert) installs reuse the existing frame for a faster, less invasive job; new-construction installs go back to the rough opening when frames are rotted or you're changing sizes. We recommend based on what we find, not a default.

Our process

1. Consultation at your home to review goals, exposures, and problem windows.
2. Precise measurement of every opening.
3. Product and energy selection, matching frame, glass, and operation to each room.
4. Permitting — window replacement in San Rafael typically requires a building permit, which we help coordinate.
5. Removal and prep, protecting your interior and inspecting frames for hidden rot.
6. Installation with proper flashing and air-sealing so the assembly sheds water and stops drafts.
7. Finish and walkthrough, confirming smooth operation and clean lines.

Local considerations in San Rafael

San Rafael's housing is unusually varied, and the right approach changes by neighborhood. Terra Linda's Eichler and mid-century homes were built with large runs of single-pane glass; replacing that glazing is one of the biggest comfort and efficiency upgrades available, provided the mid-century character is preserved. In the hills above the city, some parcels fall within designated fire hazard zones. Cal Fire released updated Fire Hazard Severity Zone maps for the area in 2025, and where a home sits in the Wildland-Urban Interface, California's Chapter 7A standards apply to exterior windows, generally calling for dual-pane assemblies with at least one tempered pane and ignition-resistant frames. We confirm whether your address is affected before specifying product.

Why homeowners here trust us

We're a Marin-based contractor, not a call center routing crews from across the bridge. Being in Larkspur keeps us close and accountable in San Rafael. See finished work in our project gallery, and read about our full Marin coverage on our service areas hub. We handle exteriors comprehensively, so if your project also involves James Hardie siding or siding replacement, one team can coordinate both.

Frequently asked questions

Do I need a permit to replace windows in San Rafael? In most cases yes. Window replacement typically requires a building permit, and we help coordinate it as part of the job.

Can you keep the mid-century look of my Terra Linda Eichler? Yes. We prioritize slim sightlines and large glass runs while upgrading to energy-efficient dual-pane units.

What if my home is in a fire hazard zone? Where a home falls in the WUI, we specify windows that meet California's Chapter 7A glazing requirements. We verify your zone first.

Retrofit or full-frame — which is right for me? It depends on the condition of your existing frames. We assess each opening and recommend the less invasive option when it's sound.
