What drives window replacement cost
- Number of windows: Whole-home replacements are priced per window, so the count is the biggest driver of the total.
- Frame material: Vinyl is the budget choice; fiberglass and wood cost more but offer better looks and longevity.
- Glass package: Double- vs triple-pane and low-E coatings raise the price but cut energy loss.
- Size & style: Large picture, bay, bow, and custom-shaped windows cost more than standard double-hungs.
- Install type & labor: Full-frame replacement costs more than a retrofit insert, and local labor rates move the total.

The San Francisco Bay Area has some of the highest contractor labor rates in the country, along with strict California permitting, energy codes, and seismic requirements.
