Whole-house costs scale with the number of windows. A small ranch with 8 windows and a two-story home with 25 windows are very different jobs, so price per window is the most useful number to compare.

What affects the price
- Number and size of windows.
- Second-story windows need more labor and sometimes scaffolding.
- Frame condition: rot found during removal adds carpentry costs.
- Lead-safe work: homes built before 1978 require EPA lead-safe practices, which can add cost.
Ways to save
- Ask for per-window line items so you can compare quotes fairly.
- Consider phasing: worst windows now, the rest next year, but expect a slightly higher per-window price.
- Check utility rebates for ENERGY STAR windows in your area.
