Why San Francisco Homes Are Different
San Francisco’s housing stock runs older than almost any major U.S. city. In neighborhoods like the Richmond, Sunset, and Noe Valley, many homes were framed before 1940, which means window openings are rarely square, framing is often redwood or fir that has shifted over decades, and retrofit work has to account for plaster walls instead of drywall. Homes in the western neighborhoods sit in daily fog, so wood frames rot faster there than in the Mission or Potrero Hill, where afternoon sun bakes south-facing sashes and causes paint to chalk and seals to crack.
Terrain matters too. Crews park on grades in Russian Hill and Telegraph Hill, carry sash and glass up staircases in Glen Park, and stage materials on flatbed carts for homes in the Marina where driveways don’t exist. Many San Francisco HOAs and the city’s Planning Department require design review for visible window changes, especially in historic districts. We’ve worked under those rules enough to know that the written spec and the permit path have to be sorted before the first old sash comes out.
Our Main San Francisco Services
Most San Francisco homeowners call us for two things: replacing windows that have stopped sealing against the fog and wind, and installing new patio doors that open a flat or a rear room to the yard. Each service has its own page with pricing and what to expect on site.
Window Replacement in San Francisco
Replacing windows in San Francisco usually means pulling original sashes from openings that haven’t been touched in 40 or 60 years, then fitting new units into framing that has settled. In the Sunset and Richmond, we see a lot of wood rot at the sill and sash corners from decades of fog. On south-facing slopes in Bernal Heights, failing seals and warped vinyl are more common from heat. Every replacement starts with a written price that covers the full install, including trim and disposal. See the full breakdown on our Window Replacement in San Francisco page.
Window Installation in San Francisco
New window installation in San Francisco covers everything from a single kitchen sash to full-floor builds in a newly framed addition. The biggest variable we see is the rough opening: in older homes the rough opening is often out of square by a quarter inch or more, which means shimming and flashing have to be done right or the window binds. On hillside lots in Diamond Heights and Twin Peaks, wind load matters more than in flat parts of the Mission. Our Window Installation in San Francisco page covers process, products, and written pricing.
Patio Door Installation in San Francisco
Patio doors in San Francisco work hardest where a rear yard, deck, or roof terrace already exists. In Noe Valley and the Castro, we replace old aluminum sliders with multi-point locking doors that seal against the evening fog. In the Richmond and Sunset, the typical job is a rear door that has swollen, stuck, or rotted at the threshold. Install includes leveling the track, flashing the opening, and ensuring the door locks without a deadbolt fight. Read more on our Patio Door Installation in San Francisco page.

FAQs About Window Company in San Francisco
Most San Francisco homeowners get a written estimate within a few business days of calling. Schedules vary by neighborhood and season, but you’ll get a firm appointment time, not a four-hour window. Call (817) 686-2228 and we’ll set the date on the phone.
Replacement windows that match the existing size and style usually do not need a permit. Changing the opening size, adding a new window, or altering visible street-facing windows in a historic district often does. We sort the permit path before any work starts so you’re never left holding an open hole and a stop-work order.
No. The price we put in writing before work starts is the price you pay, unless you ask for additional work that wasn’t in the original scope and we agree to it in writing. If hidden rot or framing damage shows up, we stop, show you, and re-quote before touching it. Call (817) 686-2228 for a free estimate.
