Window replacement cost in 2026
Fixr's 2026 pricing data puts the average installed replacement window at about $800, with a national range of $450–$1,200 per window and extremes from $200 for a small aluminum unit to $8,000 for a large bow window. HomeGnome's 2026 survey lands close by at an average of $750 and a typical range of $330–$1,170 per window. Pella, a manufacturer, quotes higher installed figures of $800–$1,600 for vinyl and $1,100–$2,200 for fiberglass or wood, which reflects brand-name windows sold through its own installers.
Cost by frame material
| Frame | Installed cost per window | Notes |
|---|---|---|
| Aluminum | $200–$800 | Cheap, poor insulation |
| Vinyl | $350–$800 | Most popular, low maintenance |
| Composite | $300–$1,200 | Wood look, no rot |
| Fiberglass | $400–$1,500 | Strong, very efficient |
| Wood | $600–$2,000 | Classic look, needs upkeep |

Whole-house window replacement
Fixr estimates $2,250–$12,000 for 5–10 windows, $4,950–$24,000 for 11–20 and $9,450–$30,000 for 21–25. A typical single-story home with 10–15 windows costs $8,000–$12,000 and a two-story home with 15–30 windows $12,000–$24,000. Installers usually discount larger orders, so replacing everything at once costs less per window than doing a few each year.
Glass and labor
Standard double-pane glass is included in most prices; a low-E coating adds about $100–$300 per window and triple-pane $300–$800 or more. Labor is roughly 30% of the total, or $100–$300 per window for standard sizes and up to $800 for a bay or bow window that needs framing and a roof. A full-frame replacement, which removes the old frame down to the studs, costs 15–20% more than an insert (pocket) replacement that slides a new unit into the existing frame; inserts work only when the old frame is square and rot-free. Permits, where required, run $50–$300.
What else moves the price
Second- and third-floor windows cost more because of ladders or lifts. Historic homes with non-standard openings can double or triple the cost. Rot in the sill or framing adds a few hundred to several thousand dollars in repairs. Spring and fall are the busiest seasons, so winter and midsummer quotes are often lower. Custom shapes and colors start at $1,000 per window.
Is it worth it?
Window replacement returns about 60–85% of its cost at resale according to Fixr, with energy-efficient units at the top of that range. The Department of Energy notes that replacing single-pane windows with ENERGY STAR models can cut heating and cooling bills by roughly 12% on average, but the payback period is long, so most people replace windows for comfort, drafts, noise and curb appeal rather than purely for savings.
Frequently asked questions
How much does it cost to replace one window? About $450–$1,200 installed for a standard vinyl double-hung; budget $800 as a middle figure. Can I replace windows myself? A handy homeowner can install an insert window, but HomeGnome found DIY material and tool costs of $700–$1,325 often match a pro's price, and a bad seal causes leaks and voids warranties. How long do new windows last? Vinyl 20–30 years, fiberglass and composite 30–50, well-maintained wood 30+. Are there tax credits? Check current federal and utility rebate programs for ENERGY STAR windows before buying; rules change year to year.
