Window replacement typically costs $300–$1,200 per window installed, with most homeowners spending $450–$750 per window for a standard double-hung vinyl replacement. A full 10-window home replacement averages $5,000–$15,000, depending on window type, material, and installation complexity.
Cost by Window Type
| Window Type | Low | Typical Installed Cost | High |
|---|---|---|---|
| Double-hung vinyl | $300 | $450–$700 | $900 |
| Casement window | $400 | $550–$900 | $1,300 |
| Sliding window | $350 | $500–$800 | $1,100 |
| Bay or bow window | $1,200 | $1,800–$3,500 | $6,000 |

Cost by Frame Material
- Vinyl: Most popular and affordable. Low maintenance, good insulation. $300–$900 installed per window.
- Fiberglass: More durable than vinyl, better insulator. $500–$1,500 per window.
- Wood: Classic look, excellent insulation, higher maintenance. $800–$2,000+ per window.
- Aluminum: Slim frames, good for modern design, less insulating. $400–$1,200 per window.
- Wood-clad (composite): Wood interior, aluminum or vinyl exterior. $600–$1,800 per window.
Energy Efficiency: Is It Worth the Upgrade?
ENERGY STAR certified windows typically add $50–$150 per window over standard options, but can reduce heating and cooling costs by 12–33% according to the EPA. For a 10-window home spending $2,000/year on energy, the payback period is often 5–10 years.
Look for the U-factor (lower = better insulation) and Solar Heat Gain Coefficient (SHGC). The right values depend on your climate — a contractor in your area will recommend the appropriate specs.
