What Affects the Cost?

1. Frame Material

Vinyl windows are the most popular at $400–$800/window installed. Fiberglass windows cost $600–$1,200 and last 30–40% longer. Wood windows run $800–$1,500 but require repainting every 5–7 years. Composite (wood + vinyl) costs $600–$1,100.

2. Window Type & Size

Standard double-hung windows run $400–$900. Bay and bow windows cost $1,500–$4,500 each due to complexity. Casement windows are $500–$1,000. Picture windows run $300–$800. Egress windows (required for basement bedrooms) cost $2,500–$5,000 including well and cover.

3. Glass Type

Standard double-pane: $100–$250/window. Low-E coating (reduces UV/heat): add $40–$80/window. Argon gas-filled: add $30–$50/window. Triple-pane: add $150–$300/window. For cold climates, Low-E + argon is the best value.

4. Number of Windows

Replacing more windows at once typically gets you a 10–15% volume discount per window. A full home replacement (15–20 windows) often comes with contractor pricing that's $75–$150/window lower than replacing 1–2 windows at a time.
