Cost to Replace All Windows in a House: Full Project Pricing
What a whole-house window replacement project costs
Replacing every window in a typical single-family home costs between $5,000 and $20,000, with most homeowners landing in the $8,000 to $14,000 range. The wide spread comes down to how many windows you have, which material you choose, and whether your existing frames can accept a pocket replacement or need full-frame work.
Before you call a contractor, run your numbers through the window replacement cost calculator to get a project estimate based on your home size and window type.
Estimated total by home size
| Home size | Typical window count | Estimated total (vinyl) | Estimated total (wood) |
|---|---|---|---|
| Small (under 1,200 sq ft) | 8 to 10 windows | $3,200 to $7,000 | $6,000 to $12,000 |
| Medium (1,200 to 2,500 sq ft) | 10 to 16 windows | $5,000 to $12,000 | $8,000 to $20,000 |
| Large (2,500 to 4,000 sq ft) | 16 to 25 windows | $8,000 to $18,000 | $14,000 to $32,000 |
| Very large (4,000+ sq ft) | 25 or more | $12,000 to $25,000+ | $20,000 to $45,000+ |
Pocket replacement vs. full-frame replacement
The two main installation methods affect cost significantly. A pocket replacement, also called an insert replacement, removes only the window sash and glass while leaving the existing frame intact. It is faster and less expensive, typically costing $300 to $700 per window. A full-frame replacement tears out the entire frame down to the rough opening, which is necessary when frames are rotted, warped, or out of square. Full-frame work costs $500 to $1,200 per window because it involves removing and replacing exterior trim, possibly siding, and interior casing.
- Pocket replacement: Best when frames are structurally sound. Faster install, lower labor cost, no exterior finish work needed.
- Full-frame replacement: Required when frames show rot, water damage, or significant drafts around the frame perimeter. Adds $100 to $400 per window over a pocket job.
Volume discounts and project timing
Replacing all windows at once almost always costs less per unit than a piecemeal approach. Contractors reduce mobilization costs, and some manufacturers offer volume pricing when you order 10 or more identical units. Many homeowners also benefit from bundling the project with other exterior work such as siding or door replacement. Spring and fall are peak booking seasons; scheduling in late winter or early summer can sometimes yield a 5 to 10 percent discount as contractors fill their calendars.
What to ask for in a whole-house quote
- An itemized list showing each window size, type, and unit price
- Whether the quote covers pocket or full-frame installation for each opening
- The glass package: double-pane low-e vs. triple-pane
- Disposal of old windows
- Interior and exterior finish work (casing, trim, caulk)
- Warranty on both the window unit and the installation labor
Get quotes from at least three licensed window contractors. Ask each to walk each room with you before pricing so they can note any problem frames or unusual openings. Get quotes from a licensed window installer in your area before committing to a scope or budget.
Frequently asked questions
Can I replace windows one at a time to spread out the cost? Yes, but you will pay more per window over time than if you replace all at once. Staggered replacement also means living with mismatched styles and performance levels across your home for years. If budget is the concern, ask contractors whether they offer phased pricing for a multi-year replacement plan.
Does replacing all windows increase home value? Homeowners typically recoup 60 to 70 percent of the project cost in added resale value, according to remodeling cost-vs-value data. The bigger gains often come from energy savings and improved curb appeal rather than a dollar-for-dollar resale return. See our full article on window replacement and home value for details.
How long does a whole-house window replacement take? A crew of two to three installers can typically complete a 12 to 16 window project in two to three days. Larger homes or complex window types can stretch the timeline to a week.
Bottom line
Replacing all windows in a medium-sized home costs $8,000 to $14,000 with standard vinyl double-pane units. Material choice, installation method, and project size are the three biggest levers on total cost.
