How Much Does Window Replacement Cost in 2026?

Bottom line for 2026: Replacement windows cost $450 to $1,800 per window installed , with most homeowners spending $800 to $1,200 per window for a quality vinyl or fiberglass double-hung. A quality unit features fusion-welded corners, multi-chambered frames, and a strong warranty. A full-house 15-window project runs $12,000 to $27,000 . Insert (pocket) replacements run 30–40% less than full-frame. Energy Star vinyl is the volume winner; fiberglass wins on long-term value; wood is for historic homes and premium retrofits.

Per-window 2026 installed pricing, including measure, removal of old sash, new unit, flashing, caulk, interior trim touch-up, and disposal:

Whole-house projects (12–18 windows) typically come in at $12,000–$27,000 , with the median 2026 project landing near $18,500 . These ranges account for variations in standard sizes, hardware finishes (e.g., bronze vs. white), and grid patterns. A non-standard size can easily push a mid-tier window into the premium price bracket. Labor constitutes 40-50% of the total and varies with local rates and installer experience.
