Trusted San Francisco window installers, free in-home quotes, licensed & insured pros, workmanship warranty.
Window installation in San Francisco has to fight one thing above all: damp. The city sits in a cool marine climate with gray skies, morning fog, and mild temperatures most of the year. That constant moisture finds every gap in old windows, and it shows up as condensation, fogged glass, and mildew on the sills.
San Francisco homes skew old and ornate. Think Victorian and Edwardian flats in Noe Valley, the Mission, the Sunset, and the Richmond, many with the iconic bay windows the city is known for. A lot still have their original single-pane wood sash. You feel it as drafts off the fog, high PG&E bills, and street noise that never quiets down. New windows put a stop to all of it.
Vetted local crews only. The same background-checked installers who measure your home are the ones who fit the glass.
Upfront written pricing. You get a line-item quote before we order, with no surprise fees tacked on later.
Your installer handles any San Francisco permits. We file with the San Francisco Department of Building Inspection, manage the Planning review for street-facing windows, and keep the job to Title 24.
Lifetime workmanship warranty. If the install ever fails, your installer comes back and fix it, on top of the manufacturer's coverage.

San Francisco sits in a Title 24 coastal climate zone. Winters are mild and wet, summers are cool and foggy, so your windows need to seal out damp air and drafts more than they need to block heat. Here is the window package we recommend in a San Francisco:
| Spec | Recommended for San Francisco | Why |
|---|---|---|
| Glass coating | Low-E 366 spectrally-selective | blocks solar heat, keeps interiors cool |
| Frame material | Vinyl or fiberglass | mild, salty coastal air, corrosion-resistant |
| Gas fill | Argon | better insulation against the heat |
| U-factor target | ≤ 0.28 | exceeds the California Title 24 requirement for your climate zone |
| SHGC target | 0.22 | beats the code cap, and it is what blocks the sun |
In San Francisco, a tight seal and a low U-factor matter most. That combination stops cold, wet air from getting in and keeps condensation off the glass on foggy mornings. Local power runs around 40.9 cents per kilowatt-hour, one of the steepest rates in the country, so sealed, efficient windows pay you back faster here than in most cities.
Window installation in San Francisco usually runs $550 to $950 per installed window, or $10,000 to $20,000 for a full home. Prices sit at the higher end because of the city's steep local costs, tight parking, and the custom sizing that Victorian and Edwardian openings often need. Bay windows and historic sash cost more than a simple square swap. With local home values near $1,250,000, quality windows are worth doing right the first time.

San Francisco is stricter than most cities. A building permit is required for every window replacement here, even a same-size swap. If your windows are visible from the street, the Planning Department also reviews the design to make sure it fits the building, and homes in historic or landmark categories face extra review with rules on materials like wood sash. Permits are filed with the San Francisco Department of Building Inspection, and the work follows California's Title 24 energy code. Your installer handles the permit, the Planning review, and code compliance for you.
