Replacing a window costs about $350 to $800 per window for standard vinyl, installed. Fiberglass runs about $400 to $1,500 and wood $600 to $2,000. For a whole house, expect roughly $8,000 to $12,000 for a single-story home with 10 to 15 windows, and $12,000 to $24,000 for a two-story home with 15 to 30.
Cost per window by frame material
| Frame | Installed, per window | Notes |
|---|---|---|
| Vinyl | $350 – $800 | Most popular; low maintenance |
| Aluminum | $200 – $800 | Slim; conducts heat |
| Fiberglass | $400 – $1,500 | Strong, stable, paintable |
| Wood | $600 – $2,000 | Classic look; needs upkeep |
| Composite | $300 – $2,500 | Wide range by brand |
Insert vs. full-frame replacement
An insert (pocket) replacement sets a new window inside the existing frame. It is cheaper and faster, but only works if the old frame is solid and square. A full-frame replacement removes everything down to the studs. It costs more but lets the installer fix rot and flash the opening properly. Make sure every quote says which method it uses.
What drives the price
- Size and style (picture, double-hung, casement, bay)
- Glass: double vs. triple pane, low-E coatings, tempered glass where code requires
- Access: upper floors need ladders or lifts
- Interior and exterior trim, and any rot repair
- Lead-safe work practices in homes built before 1978 (federal rule)
Check the energy ratings
Look for the NFRC label. Lower U-factor means better insulation; the right SHGC depends on your climate. ENERGY STAR-certified windows meet the targets for your region.

Frequently asked questions
Is it cheaper to replace all windows at once?
Usually yes per window, because setup and travel costs are shared. Many homeowners still replace the worst windows first to spread the cost.
How long do replacement windows last?
Quality vinyl and fiberglass windows commonly last 20 to 40 years; wood can last longer with maintenance.
Do new windows lower energy bills?
They can, especially when replacing single-pane or leaky windows, but the savings alone rarely pay back the full cost quickly. Comfort and noise reduction are big benefits too.
