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.
Denver cost factors
Denver's high-altitude climate brings big temperature swings, heavy snow loads, and intense sun that ages roofs faster. Labor runs above the national average, and Colorado permitting and energy codes add to project costs.
