Window Replacement: Costs, Savings and When It's Worth It
🇩🇪 Diesen Artikel auf Deutsch lesenReplacing windows can cost several hundred to over a thousand dollars per window installed, depending on size, material and installation type. Energy savings alone usually pay back slowly, so replacement makes the most sense when windows are failing, single-pane or rotting. Look for ENERGY STAR windows certified for your climate zone.

Old windows can make rooms drafty and cold. But because windows are expensive, it's worth comparing replacement with cheaper improvements first.
When replacement makes sense
- Single-pane glass in a cold or hot climate
- Rotting frames, broken seals with fog between panes
- Windows that won't open, close or lock properly
- A major renovation or siding replacement
