AfterWindow Company in San Francisco, CA
San Francisco’s window and door work is unlike anywhere else in the Bay Area. The city’s housing stock runs from 1880s Victorians with original sash windows to 1930s steel casements in the Sunset to postwar tract homes in Visitacion Valley, and each era brings its own fastening, flashing, and profile problems. Add the fog belt, salt air, and strict historic preservation rules, and you need a window company that plans for the city’s conditions before the first estimate. Call (252) 675-6980 to talk through what you’re seeing.
Why San Francisco Homes Are Different
Most San Francisco homes were built before modern window standards existed. The Victorians and Edwardians that line the Mission, Noe Valley, and Pacific Heights typically have single-pane wood double-hung windows with counterweights in the jambs. Those weights rust, the cords snap, and the sashes swell shut after decades of fog. In the Sunset and Richmond, the original 1930s and 40s steel casements are flush with the stucco, and by now many are rusted shut or leaking at the frame. Swapping them for modern vinyl or fiberglass units almost always requires custom panning and stucco repair, a detail that out-of-town crews routinely miss until the job is half open.
San Francisco’s damp, salt-laden air means wood rot and rust are the real enemies, not thermal extremes. The city rarely freezes, but the wet winters and morning fog keep frames saturated for months. Poorly flashed installations fail visibly within a few seasons, especially on the west side where wind-driven rain hits windows head-on. And if your home is in a designated historic district or is a rated building, any street-facing change can trigger a Planning Department review. Replacement windows may need to match the original wood profiles and colors, which changes both the product selection and the permitting path. We plan for all of this before we quote, so the written price you receive already accounts for San Francisco’s requirements.
High-rise and mid-rise work adds another layer. Post-1970s buildings with aluminum storefront or curtain-wall systems need engineering coordination and HOA approval before anyone touches a frame, and large window assemblies carry strict seismic anchoring requirements. Our team is used to working with building management, not around them.
Our Main San Francisco Services
Homeowners in San Francisco call us most often about three jobs: replacing windows that have outlived their seals, repairing windows that won’t stay open or won’t close, and replacing front doors that no longer close with confidence. Each service has its own page with pricing and San Francisco-specific details.
Window Replacement in San Francisco
Replacement work in San Francisco is shaped by the building’s age and the street it faces. A Sunset stucco home with rusted steel casements needs custom panning and stucco tie-in, while a Marina flat with original wood sashes may call for a like-for-like wood replacement to clear historic review. We carry professional-grade lines including PGT and CGI so we can match the right product to the building rather than pushing one brand. The written quote you get accounts for flashing, trim, and any stucco or siding repair the job requires. Details are on the Window Replacement in San Francisco page.
Window Repair in San Francisco
Fog-city repairs are usually about moisture, not impact. Stuck sashes, snapped counterweight cords, rotted wood frames, failed seals that fog between the glass, and rusted operators on old casements are the calls we take most often from the Richmond, Outer Mission, and Glen Park. We repair what can be repaired and say so plainly when a replacement makes more financial sense. Every repair carries a written guarantee, and if it fails within the year, the second visit is free.

Front Door Replacement in San Francisco
A San Francisco front door has to do three things: close securely, seal against wind-driven rain, and suit a building that may predate standard door rough openings. We measure for out-of-square frames, rot at the threshold, and hardware that no longer engages cleanly, then quote a Therma-Tru or ViewLux door sized to the actual opening. The old door and hardware are removed and hauled, and the new door is installed with new weatherstripping and a threshold that keeps fog out. See Front Door Replacement in San Francisco for full pricing and process.
