Labor rates vary depending on the city.- Chicago: $150–$300 per window

How to Get the Best Price for Window Installation?
- Get at least 3 quotes from local window installation contractors.

- Look for seasonal discounts — many installers offer deals in off-peak months (spring or fall).
Is It Worth Paying More for Professional Installation?

Average Cost to Replace All Windows in a House (Illinois)
| Home Size | Estimated Total Cost (All Windows) |
|---|---|
| Small home (8–10 windows) | $4,000 – $8,000 |
| Medium home (12–16 windows) | $6,500 – $13,000 |
| Large home (20+ windows) | $10,000 – $25,000+ |
