Quick Answer
The national average cost to have a replacement window installed ranges from $632 to $1,050 per window in 2026, including both materials and professional labor. Vinyl windows sit at the affordable end, while wood and large bay windows can cost several times more.
Average Cost by Frame Material
Frame material is the single biggest cost driver. Here is what homeowners pay per window, installed, by material:
| Frame Material | Installed Cost per Window | Notes |
|---|---|---|
| Vinyl | $390 – $1,600 | Most affordable and popular for standard sizes |
| Aluminum | $390 – $850 | Economical, but less energy-efficient |
| Fiberglass | $500 – $2,200 | Strong and durable, premium mid-range pick |
| Wood | $1,100 – $3,000+ | Premium aesthetic, requires more maintenance |
Vinyl remains the most popular choice for standard sizes — affordable, low-maintenance, and energy-efficient. See our detailed vinyl window replacement cost breakdown for model-level pricing.
Average Cost by Window Type
Operating style matters too. More complex mechanisms and larger glass areas cost more:
| Window Type | Installed Cost per Window |
|---|---|
| Double-Hung | $430 – $2,400 |
| Casement | $590 – $2,990 |
| Sliding | $650 – $2,660 |
| Bay or Bow | $1,700 – $10,200+ |
What Else Affects the Price
Labor: $150–$500 per window
Labor varies with job complexity and local rates. Full-frame replacements, second-story work, and rotted-frame repairs sit at the high end. Get the full picture with our window installation cost calculator.
Removal & disposal: $100–$260 per unit
Taking out the old window, hauling debris, and disposing of glass and frames is often a separate line item. Confirm whether your quote includes it.
Project size: bulk discounts are real
Replacing all windows at once usually lowers the per-window cost — contractors save on mobilization and pass part of it on. Read our guide on whether it is cheaper to replace all windows at once.
How to Use This Average
- Budget: multiply $632–$1,050 by your window count for a realistic ballpark.
- Compare: quotes far above this range need justification (premium materials, structural work).
- Verify: check our window replacement ROI calculator to see how the investment pays back through energy savings and resale value.
