How Much Does It Cost to Replace Windows? The 2026 Guide
Window replacement costs $300-1,200 per window installed. Here is how to decide if it is worth the investment.
Average cost per window installed: vinyl double-hung $300-600, wood double-hung $500-1,000, fiberglass $600-1,200, triple-pane $800-1,500. A whole-house replacement (15-20 windows) costs $4,500-24,000. Labor accounts for 30-50% of the cost — this is not a DIY project for most homeowners.
When to Replace vs Repair
Replace when: windows are 20+ years old, single-pane, visibly rotting, fogging between panes (seal failure), or you feel drafts with windows closed. Repair when: hardware is broken but glass and frames are solid, weatherstripping has worn out ($5-15 per window DIY fix), or paint is peeling but the wood is sound.
Energy Savings Reality Check
New windows save $125-465/year on energy bills according to Energy Star. At a cost of $10,000-20,000 for whole-house replacement, the energy payback period is 20-40+ years — longer than the windows last. The real value of new windows: comfort (no drafts, less noise), aesthetics, and increased home value (70-80% cost recovery at resale). Do not replace windows primarily for energy savings — the math rarely works out.
