Windows & Doors costs, frame materials and planning guides
Windows are sold by the opening and quoted by the house. The gap between those two numbers is where the money goes.
What replacement windows cost
A whole-house window replacement runs $5,000 – $20,000 in most American homes, and the single biggest lever is not the glass but the frame: vinyl at the bottom, fiberglass and clad wood at the top, with a spread of roughly four to one between them.
Every window guide here starts from the same arithmetic. A quote is a price per opening multiplied by the number of openings, then adjusted for the things that make one opening harder than another: a second floor, a rotten sill, an arch, or a code that demands impact-rated glass.
Nothing on this site asks for your address or your phone number to show you a figure. When you are ready for real quotes, the checklists tell you what a serious window bid has to name before it can be compared with another one.
What moves the price of replacement windows
$5,000 $20,000
Whole-house window replacementEvery window quote moves on:
- Frame material; aluminum to fiberglass is a four-to-one spread
- Insert versus full-frame replacement
- Opening count, and how many are standard sizes
- Glazing package, and whether code demands impact rating
Figures on this page are indicative national brackets, not quotes. Your number depends on the size, complexity and condition of the job itself, and on what local crews are charging when you buy. Use them to judge a bid, not to replace one.
What each window frame material costs installed
| Frame | Installed cost per opening, materials and labor | Lifespan | Who it suits |
|---|---|---|---|
| Aluminum | $580 – $1,150 | 20 – 25 years | Cheapest to buy and the worst insulator: metal conducts, so it sweats and loses heat unless the frame is thermally broken. |
| Vinyl | $650 – $1,300 | 20 – 30 years | What most American houses get, and rightly: the best insulation per dollar. It cannot be painted and it is what it is for good. |
| Wood | $600 – $2,000 | 30 – 60 years | The widest band on this table, and it is real: a builder-grade pine sash and a premium wood unit are the same material and nothing like the same window. The only frame you can repair rather than replace, and the only one that fails outright if you stop painting it. |
| Clad wood | $1,100 – $2,400 | 30 – 50 years | Wood inside, aluminum or fiberglass skin outside. Buys the interior look without the exterior repainting, and starts higher than solid wood because you are paying for two materials. |
| Fiberglass | $850 – $1,850 | 30 – 50 years | Moves at almost the same rate as the glass it holds, so the seals last. The quiet premium choice on a house you keep. |
Installed cost covers the unit and the labor to fit it in an existing opening. Full-frame replacement, rotten sills, upper floors and impact glazing are priced on top; the cost guide sets out how each line is billed.

Window questions, answered
How do window companies price a job?
Per opening, then multiplied. A quote takes a rate for the unit and the labor to fit it, multiplies by the number of windows, and adds line items for full-frame work, odd sizes, upper floors and disposal. Volume usually buys a lower rate per opening.
Is vinyl or fiberglass worth the difference?
Fiberglass costs roughly twice what vinyl does and expands at almost the same rate as glass, so the seals last longer. On a house you intend to keep for decades that pays; on a house you plan to sell, vinyl is the sensible buy.
Do new windows pay for themselves in energy savings?
Rarely on energy alone. Replacing single-pane windows cuts a real amount from a heating bill, but the payback runs decades. Comfort, noise and rot are the honest reasons to replace; the energy saving is a bonus, not a business case.
What is the difference between insert and full-frame?
An insert sets a new unit inside the existing frame, which is faster and cheaper and keeps whatever condition that frame is in. Full-frame takes the opening back to the studs, costs 15 to 35 percent more, and is the only option once the frame has rot.
How long do replacement windows last?
Twenty to forty years for vinyl, thirty to fifty for fiberglass and clad wood, and longer for wood that is genuinely maintained. What fails first is almost never the frame: it is the seal between the panes, which shows up as permanent fog.
