How Much Do Replacement Windows Cost in 2026?
Replacing windows costs $400–$900 per window for standard vinyl double-pane units, installed. A typical home with 10 windows costs $4,000–$9,000 total. Premium materials like fiberglass or wood-clad can double or triple that figure.
Insert vs. full-frame replacement
Insert replacement keeps the existing frame in place and is 20–30% cheaper. It is ideal when frames are in good condition. Full-frame replacement removes everything down to the rough opening — necessary when frames are rotted, damaged, or if you want to change the window size.
Energy savings
Upgrading from single-pane to double-pane Low-E windows can reduce heating and cooling costs by 10–25%. Triple-pane windows deliver additional savings in extreme climates.
