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.
Ontario cost factors
California's Inland Empire and high desert see hot, dry summers that make air conditioning and sun-resistant roofing priorities. Labor runs a little above the national average — below the coast — and projects still fall under California's permitting and energy rules.
