Window Company in San Rafael, CA
Westlight Windows & Doors is the San Rafael window company built for homes that sit in a valley, not on the coast. Our crews work in the specific conditions that define San Rafael: afternoon heat that runs 15-20°F hotter than Sausalito or Tiburon, winter bay winds that chew through old wood frames, and hillside fire zones where a simple window swap can pull a Marin County permit review. If you’re replacing windows or doors here, the product spec matters more than it does ten miles south. Call (903) 354-7134 and we’ll walk you through what your house actually needs.
Why San Rafael Homes Are Different
San Rafael doesn’t age the way coastal Marin ages. Terra Linda, the large planned community built mostly in the 1950s and 60s, still carries original single-pane aluminum sliders in many ranch-style tract homes. Those windows were under-insulated when they were installed and now run far past their functional life, especially under San Rafael’s inland heat load. Downtown and Canal district blocks add Craftsman bungalows and Spanish Colonial homes from the 1920s-40s, where wood-frame windows and doors show seasonal rot and paint failure from winter rain and northerly bay winds.
The bigger variable is fire-zone compliance. Large portions of Dominican, Sun Valley, and sections of East San Rafael sit within CAL FIRE-designated Very High Fire Hazard Severity Zones. On those parcels, a window or door replacement often triggers Marin County building department review for fire-rated assemblies: tempered or multi-pane glass, non-combustible frames, and ember-resistant gap sealing. A contractor who only does flatland Title 24 work in Petaluma can get a permit flagged here because the fire-hazard overlay requires a closer look at the rough opening before the county signs off. That single requirement is the biggest cost and spec driver separating San Rafael jobs from San Anselmo or Novato work.
Our Main San Rafael Services
Most San Rafael homeowners call us for one of three jobs: swapping failed windows, installing new-construction windows during a remodel, or replacing a front or patio door that no longer seals or swings true. Each service has its own San Rafael page with pricing and details.
Window Replacement in San Rafael
We replace windows that fog between the panes, stick in their tracks, or let afternoon heat pour through uncoated glass. San Rafael’s valley position pushes summer temperatures well above coastal Marin, so we spec low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) more often than we would in Sausalito. In fire-zone neighborhoods, replacement glass may need to be tempered and the frame assembly may need ember-resistant detailing before the county approves the permit. Read the full breakdown on our Window Replacement in San Rafael page.

Window Installation in San Rafael
New-construction and remodel window installation in San Rafael means working with framing that has settled, openings that are no longer square, and exterior stucco or siding that has to be cut back and re-sealed. On hillside lots, we also see more wind-driven rain against the window plane, so flashing detail gets more attention here than on a flat lot in Novato. Every San Rafael installation gets a written price before work starts, with measurements and opening conditions confirmed at the walkthrough. That process, start to finish, is on the Window Installation in San Rafael page.

Door Installation in San Rafael
San Rafael doors deal with afternoon sun on west-facing entries and winter wind against north-facing ones – both failures show up as warped slabs and failing weatherstripping within a few seasons. Older Spanish Colonial and Craftsman homes downtown often have non-standard rough openings, so we measure and order to the actual frame rather than forcing a stock door into a 1930s opening. In fire-hazard zones, entry door assemblies may need non-combustible or ignition-resistant materials to clear permit. Details and local pricing are on the Door Installation in San Rafael page.

Brands We Service in San Rafael
We carry eight manufacturer lines and stock common parts for ViewLux, PGT, CGI, and CWS locally, so San Rafael orders don’t sit in a warehouse queue for standard sizes. Impact-rated PGT and CGI are common in hillside fire-zone specs; ViewLux and CWS cover a lot of the mid-century and Spanish Colonial replacements. See the full list on our brands page.
Pricing for Window Company in San Rafael, CA
These are the price ranges we quote most often in San Rafael. Every customer gets a written, line-item price before any work starts – no revised invoices at the door.
| Service | Typical range in San Rafael |
|---|---|
| Single window replacement | $850-$2,800 installed |
| Standard vinyl window | $450-$750 |
| Standard aluminum window | $500-$850 |
| Premium window (fiberglass/composite) | $900-$2,400 |

What pushes a San Rafael quote toward the top of those ranges is usually fire-zone compliance: tempered or multi-pane glass, non-combustible frame materials, and ember-resistant sealing all add cost and permit time that a flatland replacement wouldn’t carry. The Kingswell Guarantee applies on every one of these jobs: written price before work, a committed arrival window, a clean site, and a written guarantee on the completed work.

FAQs About Window Company in San Rafael
Most San Rafael estimates are scheduled within a few days, depending on weather and how full the crew calendar is. Call (903) 354-7134 and a real person picks up 24/7 – no chatbot, no voicemail box – and can book your walkthrough immediately. Estimates are free and the written price is firm before work starts.
Yes, often. A like-for-like window replacement can be a simple swap elsewhere, but in San Rafael’s Very High Fire Hazard Severity Zones – Dominican, Sun Valley, and parts of East San Rafael – the county overlay review frequently requires fire-rated assemblies and a structural check of the rough opening. We handle permit paperwork as part of the job. Call (903) 354-7134 to confirm whether your parcel falls in the zone.
No, and that’s the whole point of the Kingswell Guarantee. We write the price before any work starts after measuring the actual opening and confirming the condition of the frame at the walkthrough. If hidden rot or framing damage appears mid-job, we stop, show you what we found, and price the correction in writing before proceeding. You approve every number before it happens. Call (903) 354-7134 for a free estimate.

What San Rafael Customers Say
"Two bedroom windows that never opened and one that wouldn't stay up. All replaced in an afternoon. The crew was clean, hauled off the old frames, and the quote held."
- Colette Rhee"Got quotes from three companies. Westlight wasn't the cheapest but they were the only one who measured everything carefully and put it all in writing. Worth it. No surprises on install day."
- Craig Dillard"Our sliding patio door had come off its track years ago and we just lived with it. New one is smooth as butter. They hauled off the old one and vacuumed up before they left."
