The average cost to replace windows in 2026 is $300–$1,200 per window installed, with most homeowners spending $450–$750 per window. Replacing all windows in a typical 10-window home runs $4,500–$7,500 including labor. Prices vary significantly by material, style, size, and local labor rates.
Replacement Window Cost by Material
Your choice of frame material is the biggest factor in price per window.
| Material | Cost per Window (Installed) | Pros | Cons |
|---|---|---|---|
| Vinyl | $250–$600 | Low maintenance, energy-efficient, affordable | Limited color options |
| Aluminum | $300–$700 | Durable, slim frames, modern look | Poor insulation, conducts cold/heat |
| Wood | $700–$1,500 | Classic look, excellent insulation | Requires painting/staining, higher maintenance |
| Fiberglass | $600–$1,400 | Very durable, great insulation, paintable | Higher upfront cost |
| Composite | $500–$1,200 | Wood look with vinyl durability | Higher cost than vinyl |
Vinyl windows are the most popular choice for budget-conscious homeowners. They require almost no maintenance, insulate well, and are available in standard and custom sizes.
Replacement Window Cost by Style
Window style affects both material cost and installation complexity.
| Window Style | Average Cost (Installed) |
|---|---|
| Single-hung | $250–$550 |
| Double-hung | $300–$700 |
| Casement | $350–$800 |
| Sliding | $300–$700 |
| Bay or bow | $1,000–$3,500 |
| Skylight | $900–$2,500 |
| Picture window | $400–$900 |
| Egress window | $2,500–$5,000 |
Double-hung windows — where both the upper and lower sash open — are the standard choice for most homes and offer the best balance of cost and functionality.
Labor Cost for Window Replacement
Labor typically accounts for 30–40% of the total project cost. Expect to pay $100–$300 per window in installation labor depending on your region and the complexity of the installation.
Factors that raise labor costs:
- Custom or non-standard window sizes
- Second-story or difficult-access windows
- Rot or structural damage around the frame requiring repairs
- High-cost metro areas (New York, San Francisco, Boston)
Factors that lower labor costs:
- Standard window sizes that require no custom cuts
- Single-story home with easy access
- Replacing many windows in one visit (volume discount)
Worked Example: 10-Window Home Replacement
A homeowner in the Midwest replacing 10 double-hung vinyl windows on a single-story home:
| Item | Cost |
|---|---|
| 10 vinyl double-hung windows (materials) | $3,200 |
| Installation labor (10 × $150) | $1,500 |
| Disposal of old windows | $150 |
| Total | $4,850 |
The same project with wood windows would cost approximately $9,000–$12,000.
ENERGY STAR Windows: Are They Worth It?
ENERGY STAR-certified windows meet strict insulation standards set by the EPA and DOE. They typically cost 10–15% more than standard windows upfront, but the Department of Energy estimates they can reduce heating and cooling costs by 12–15% per year.
On a $1,500 annual energy bill, that’s $180–$225 in annual savings — meaning the premium pays back within 4–7 years.
Look for:
- U-factor below 0.30 (lower = better insulation)
- Solar Heat Gain Coefficient (SHGC) suited to your climate zone
- ENERGY STAR label for your region (Northern, North-Central, South-Central, or Southern)
How to Save on Window Replacement
- Get 3+ quotes. Window prices vary widely by contractor. Collect bids from at least three licensed window installers.
- Buy directly from manufacturers. Companies like Pella, Andersen, and Milgard sell direct and through big-box stores — prices differ.
- Replace in off-season. Winter and early spring are slower seasons for contractors; you may negotiate a lower rate.
- Check utility rebates. Many utility companies offer $25–$100 per window in rebates for ENERGY STAR replacements. Visit the DSIRE database to find local incentives.
- Check federal tax credits. The Residential Clean Energy Credit allows a 30% tax credit on energy-efficient home improvements including qualifying windows through 2032.
- Replace only the damaged units. If only a few windows are drafty or broken, replace just those rather than the whole house.
Signs It’s Time to Replace Your Windows
- Drafts felt near the edges even when closed
- Condensation or frost between double-pane glass (broken seal)
- Difficulty opening, closing, or locking
- Visible rot, warping, or water stains on frames
- Single-pane glass (poor insulation)
- Noticeable outside noise that wasn’t there before
