What drives window replacement cost
- Number of windows is the main driver of the total.
- Frame material: vinyl is cheapest, then aluminum and fiberglass, with wood at the top.
- Installation type: an insert into the existing frame costs less than a full-frame replacement.
- Window size, style (double-hung, casement, bay), and glass package (double or triple pane, low-E).
- Whether rotted frames or trim need repair.
- Regional labor rates.
Key cost factors
Per-window pricing
Windows are usually priced per opening, including labor. Standard double-hung vinyl windows sit at the low end. Large picture windows, bays, and specialty shapes cost more per unit.
Insert versus full-frame
An insert (or pocket) replacement fits a new window into the sound existing frame and is faster and cheaper. A full-frame replacement removes everything to the rough opening and is needed when frames are rotted or you are changing size.
Glass and efficiency
Double-pane low-E glass is standard. Triple-pane and gas fills add cost but improve comfort and energy savings in extreme climates.
