Window replacement cost depends on window type, material, size, and installation complexity. While replacing a single window can be relatively affordable, full-home window replacement projects often cost several thousand dollars.
This guide breaks down average window replacement costs and explains what factors have the biggest impact on price.
Average Window Replacement Cost
Most homeowners spend between $300 and $1,200 per window installed, depending on material and efficiency.
| Window Type | Installed Cost per Window |
|---|---|
| Basic vinyl window | $300 – $700 |
| Mid-range vinyl or composite | $600 – $1,200 |
| Wood window | $900 – $1,800 |
| Fiberglass window | $1,000 – $2,000 |
| Custom or specialty windows | $2,000+ |
Cost by Number of Windows
Replacing multiple windows at once increases total cost but often reduces labor cost per window.
| Number of Windows | Total Cost Range |
|---|---|
| 5 windows | $2,000 – $6,000 |
| 10 windows | $4,500 – $12,000 |
| 15 windows | $7,000 – $18,000 |
| 20+ windows | $10,000 – $30,000+ |
What Affects Window Replacement Cost
Several factors influence window replacement pricing:
- window material (vinyl, wood, fiberglass)
- window size and shape
- number of panes (single, double, triple)
- energy-efficiency upgrades
- removal of old windows
- installation difficulty
- local labor rates
Custom sizes, older homes, and structural repairs typically increase costs.
Window Cost vs Installation Cost
Window replacement pricing usually breaks down as:
- Window unit: 60–70% of total cost
- Labor and installation: 30–40%
Labor costs may increase for second-story windows, masonry walls, or older framing.
Energy-Efficient Windows and Cost
Energy-efficient windows cost more upfront but may reduce heating and cooling expenses.
Upgrades that increase cost include:
- double or triple-pane glass
- low-E coatings
- gas-filled insulation
Some homeowners may qualify for rebates or tax credits depending on location.
Window Repair vs Replacement
Window replacement is often recommended when:
- frames are damaged or rotting
- seals have failed and glass is fogged
- energy loss is noticeable
- repairs are frequent
Minor issues like broken hardware or small drafts may be repairable.
Bottom Line
Window replacement costs vary widely, but most homeowners should expect to pay several hundred dollars per window. Material choice, efficiency upgrades, and installation complexity are the biggest cost drivers.
