Window Replacement Cost in 2026

Window costs depend on size, frame material, glass package, and whether you’re doing inserts or full-frame installs.

Typical cost per window (installed)

Insert vs full-frame replacement

• Insert: faster, often cheaper, keeps existing frame if it’s in great shape.
• Full-frame: better long-term if there’s rot; more labor.

What increases window cost

1. Large sizes (picture windows, sliders)
2. Upgraded materials (fiberglass/wood)
3. Tempered glass requirements
4. Exterior trim/siding repair
5. Multiple stories / difficult access
