How Much Does It Cost to Replace Windows?
Replacing windows typically costs between $200 and $1,800 per window, with the national average around $500 to $700 for a standard double-pane unit installed. The final price depends heavily on the window material, size, style, and whether the project involves full-frame replacements or retrofits that fit inside the existing frame.

What Drives the Cost of Window Replacement
Material choice is the single biggest factor. Vinyl windows are the most affordable and mid-range option, while wood-clad and fiberglass models cost more but offer better durability and insulation. Custom sizes, specialty shapes like arches or circles, and energy-efficient coatings or gas fills between panes add to the price. Labor rates vary by region, and difficult access, removing old lead-paint-coated frames, or structural repairs can push costs higher.
Cost Ranges by Window Type
| Window Type | Avg. Cost per Window (Installed) | Notes |
|---|---|---|
| Single-hung vinyl | $200 – $500 | Most budget-friendly option |
| Double-hung vinyl | $300 – $700 | Popular for ease of cleaning |
| Casement (vinyl or wood) | $350 – $800 | Swing outward, good ventilation |
| Double-pane energy star | $400 – $1,000 | Standard upgrade for efficiency |
| Fiberglass or wood-clad | $600 – $1,800 | Higher durability and insulation |
| Custom or specialty shapes | $800 – $2,500+ | Arches, circles, oversized units |
Should You Replace All Windows at Once
Replacing all windows in a home at once often lowers the per-unit cost because contractors can bundle materials and reduce mobilization charges. A full-house project might run $8,000 to $25,000 depending on the number of windows and the quality tier chosen. Partial replacements make sense when a few windows are damaged or drafty, allowing you to spread costs over time while still improving comfort and energy efficiency.
Hidden Costs to Budget For
Beyond the window unit and labor, plan for removal and disposal of old windows, which runs $50 to $150 per unit. Trim and caulking repair, interior drywall patching, and any needed structural work are extras that can add $100 to $500 per opening. Permits are required in some municipalities and may cost $50 to $200, so check local building codes before starting.
