How much does window replacement cost?
Replacement windows are priced per window, not by area. Installed prices for a standard double-pane insert, where new sashes go into the existing frames:
- Aluminum
- $600–$1,000 per window
- Vinyl
- $675–$1,125 per window
- Fiberglass / composite
- $1,080–$1,800 per window
- Wood
- $1,470–$2,450 per window
Replacing 6 vinyl inserts usually comes to $4,050 to $6,750. That includes one flat fee for measuring, delivery and disposal, which is why 1 or 2 windows cost more per window than a whole house.
The size of each opening, triple-pane glass, full-frame installation and any rot all change the final price. Your contractor confirms the quote after measuring the openings.
