How Much Does Window Replacement Cost?

Updated August 19, 2026 · every figure is cited to a public source below

Window pricing is where published numbers disagree the most — so start with the strongest data. This Old House’s 2026 survey of 1,000 window customers found homeowners actually paid $517 per installed window on average, about $7,183 per project (seven windows). Angi’s dataset of 13,122 verified projects lands almost on top of it: a $7,348 average project, typically $3,436–$11,839.^[1][2]

Around those averages, cost databases publish per-window ranges of roughly $450–$1,500, and premium manufacturers quote installed prices that START near $800. All three kinds of number are real — they’re measuring different things, and knowing which is which is most of what you need to read a window quote.^[3][4][6]

Three kinds of “average” — and why quotes ignore two of them

The $517 survey figure is what real projects actually settled at. Database ranges ($450–$1,500 per window) describe the menu of what CAN be bought, from builder-grade vinyl to oversized fiberglass. And manufacturer guides sit above both: Pella quotes installed vinyl at $800–$1,600 and fiberglass at $1,100–$2,200 per window — a premium brand’s floor is higher than the market’s average. If your quotes come from big-brand dealers, compare them against other big-brand dealers, not the survey average.^[1][3][6]

Frame material moves less than the brochures suggest

In the survey of what people actually paid, the whole material spread is under $120 per window: aluminum $453, vinyl $472, composite $513, wood $544, fiberglass $564. The database ranges are far wider (vinyl alone spans $200–$1,500 at HomeGuide) — because size, glass package, and brand move the price more than the frame material itself.^[1][3]

Insert vs full-frame: the fork in every window quote

An insert (retrofit) replacement drops a new window into your existing frame — $100–$300 per window in Angi’s data. Full-frame replacement removes everything down to the rough opening and runs $180–$1,500 per window. Inserts are only as good as the frame they sit in: if there’s rot, full-frame isn’t an upsell, it’s the repair. Ask every bidder which one they priced — two “window replacement” quotes that differ here are different projects.^[2]

What makes the price jump

The quantified drivers in the published data:

Hidden damage: rot or structural repairs discovered during replacement add $100–$2,000+ — the most common surprise line.^[2]
Custom or oversized windows: +25–75% over standard sizes per This Old House’s RSMeans-based guide; Angi says +25–50%.^[1][2]
Upper stories and tight access push labor from the standard $100–$300 toward $600+ per window.^[2]
Glass upgrades: Low-E coatings add 10–20% per HomeGuide, or $300–$1,100 per window in Angi’s and Fixr’s identical figures.^[3][2][4]
Egress (basement) windows are the wildest published spread — $300 to $8,000 depending entirely on whether the figure includes cutting the opening, the window well, and excavation. Never compare an egress bid to a bedroom-window number.^[3][2]

How to find out what YOUR windows cost

A comparable window bid lists the count, each window’s size and style, the exact product line, insert versus full-frame per opening, the glass package, and a stated rate for rot found at tear-out. Since brand choice alone can double a quote, get bids from more than one tier of installer.

Describe the project once on Getstimate — how many windows, roughly what sizes, a photo or two — and compare line-itemed proposals from local window pros side by side, free and private.

Common questions

How much does it cost to replace one window?

Surveyed homeowners paid $517 per installed window on average in 2026, and typical database ranges run $450–$1,500 depending on size, material, and glass. Labor is $100–$300 of that for a standard, ground-floor opening.

How much does it cost to replace all the windows in a house?

Angi’s 13,122-project dataset averages $7,348, and a typical three-bedroom house with 10–12 standard double-hung windows runs $7,000–$9,000. The surveyed average project — seven windows — came in near $7,200.

What is the difference between an insert and a full-frame replacement?

An insert keeps your existing frame and costs $100–$300 per window; full-frame replacement removes frame and all at $180–$1,500 per window. Inserts need a sound frame — rot makes full-frame the honest recommendation, not an upsell.

Why is my quote so much higher than the averages here?

Usually brand tier: premium manufacturers quote installed vinyl from about $800 per window — above the survey average for the whole market. Custom sizes (+25–75%) and upgraded glass packages compound it. It isn’t necessarily padding; it’s a different menu.

These figures are published national averages and ranges — context for planning, not a quote. Your project's real cost depends on your area, the site, materials, and scope, and the only way to know it is estimates from pros looking at yourproject. That's what Getstimate is for, and it's free.
