Replacing old windows improves comfort, curb appeal, and energy bills. The 2026 national average is about $1,050 per window, which works out to roughly $8,000 to $15,000 for a typical whole-home job of ten to fifteen windows.
What you’re paying for
Each window’s price bundles the unit itself and installation labor, plus trim, capping, and disposal of the old units across the project. The window type and glass package drive most of the per-unit cost, while the number of windows drives the total. Because crews price in bulk, doing the whole house at once usually lowers the per-window rate.
Cost by window type
A simple double-hung and a custom bay window are very different line items. The table below shows typical installed pricing by window style so you can estimate a mixed-window home.
Insert vs. full-frame replacement
This choice quietly sets your budget. An insert (or “pocket”) replacement fits a new window into the existing frame — cheaper, faster, and ideal when the old frame is sound. A full-frame replacement removes everything down to the studs; it costs more but lets you fix hidden rot, re-flash, and seal air leaks. If your frames are solid, inserts save real money; if they’re rotting, full-frame is worth it.
What about energy savings?
New low-E, double- or triple-pane windows cut drafts and lower heating and cooling bills, especially replacing single-pane originals. Just temper expectations: the energy savings alone rarely pay back the project quickly — comfort, noise reduction, and curb appeal are the bigger wins.
How to save on windows
- Replace all windows at once for volume pricing.
- Choose vinyl unless you have a specific reason to upgrade.
- Use inserts where the existing frames are solid.
- Check state and utility rebates for qualifying energy-efficient windows.
| Item | Typical range | Notes |
|---|---|---|
| Standard double-hung window | $500 – $1,100 each | National average about $1,050 installed |
| Casement / sliding window | $550 – $1,200 each | – |
| Bay or bow window | $1,500 – $4,500 each | – |
| Installation labor | $150 – $400 each | Often bundled into the per-window price |
| Trim, capping & disposal | $300 – $1,500 | – |
| Option | Typical range | Notes |
|---|---|---|
| Double-hung / single-hung (vinyl) | $450 – $1,000 | Most common |
| Casement or sliding | $550 – $1,200 | – |
| Picture / fixed | $400 – $1,000 | – |
| Bay or bow | $1,500 – $4,500 | – |
| Wood-clad or fiberglass | $800 – $2,500 | – |
What affects the price
- Number of windows Whole-home jobs scale with window count, though per-window labor often drops in bulk.
- Window type & material Vinyl is most affordable; fiberglass and wood-clad cost more. Specialty shapes cost the most.
- Glass package Double vs. triple pane, low-E coatings, and gas fills raise the price and the efficiency.
- Full-frame vs. insert Insert replacements are cheaper; full-frame replacement costs more but fixes rot and air leaks.
- Install complexity Upper floors, large or custom shapes, and rotted framing add labor.
Window replacement cost by state
Where you live can change the price as much as the options you pick. Labor is a big part of the bill, and construction workers are paid more in some states than others. A typical window replacement job costs about $5,900 to $17,600 in Hawaii (17% above the U.S. average). In Arkansas, it costs about $4,300 to $12,800 (15% below the U.S. average).

Common questions
- How much does it cost to replace one window?
- The 2026 national average is about $1,050 per window installed. Standard vinyl units run $700–$1,200, basic models start near $400, and large or premium windows can exceed $2,500.
- Is it cheaper to replace all windows at once?
- Usually yes. Contractors often lower the per-window price for a whole-home job, and you pay one mobilization and disposal fee. A 10–15 window home typically runs $8,000–$15,000.
- Do new windows save money on energy?
- Energy-efficient windows can noticeably cut heating and cooling bills, especially when replacing old single-pane units, and may qualify for state or utility rebates.
- Vinyl vs. fiberglass windows — what's the difference in cost?
- Vinyl is the budget-friendly standard. Fiberglass costs roughly 10–30% more but is more durable, paintable, and handles temperature swings better.
- What is insert vs. full-frame replacement?
- An insert fits a new window into the existing frame — cheaper and faster. A full-frame replacement removes everything to the studs — pricier, but it lets you fix rot and air leaks.
- How long do replacement windows last?
- Quality vinyl and fiberglass windows last 20–40 years; wood windows can last longer with maintenance. Failed seals (fogging between panes) are the most common reason to replace sooner.
- Are there rebates for energy-efficient windows in 2026?
- Federal energy-efficiency credits for windows largely ended after 2025, but some states and utilities still offer rebates for qualifying low-E windows. Check local programs.
