How much does window replacement cost?
Replacing a window costs about $477 on average installed, with most projects landing between $395 and $631 per window. The two biggest factors are the frame material and the window style, followed by size, glass package, and how many you replace at once. A whole-home job of 10–25 windows commonly runs $4,700 to $12,000.
Window cost by frame material (installed, per window)
| Material | Typical cost / window | Notes |
|---|---|---|
| Aluminum | ~$448 | Affordable, slim frames, less insulating |
| Fiberglass | ~$491 | Durable, stable, energy-efficient |
| Vinyl | ~$527 | Most popular — low cost, low maintenance |
| Composite | ~$529 | Strong, wood-like without the upkeep |
| Wood | ~$567 | Premium look, more maintenance |
What drives window cost up or down
- Frame material: aluminum and vinyl are cheapest; wood is the premium option.
- Style: single-hung and picture windows cost less; casement and bay/bow cost more.
- Glass package: double-pane is standard; triple-pane and low-E coatings add cost and efficiency.
- Size & count: larger and custom windows cost more; replacing many at once can lower the per-window price.
- Install type: a full-frame replacement costs more than an insert into a sound existing frame.
- Location: labor rates vary by region.
