Window Replacement Cost in 2026
Window replacement costs about $750 per window installed in 2026, and the average whole-house project runs $7,347. But the per-window spread — $300 to $2,500 — is so wide that the only honest way to budget is by window type and frame material, which is how this guide is organised.
Quick answer: what it costs in 2026
| Window replacement (installed) | Low | Typical | High |
|---|---|---|---|
| Per window, all types (Angi average: $750) | $300 | $750 | $2,500 |
| Whole-house project (Angi data, 17,857 projects) | $3,436 | $7,347 | $11,836 |
| 10–12 standard double-hung windows, whole home | $7,000 | $8,000 | $9,000 |
Notice what the project average implies: at $750 per window, the average $7,347 project is roughly a ten-window job with standard windows. Quotes far above the band are usually one of three things — premium frame materials, full-frame rather than insert installation, or a dealer channel whose price includes the showroom. All three are visible in the tables below if you know where to look.
Estimates based on published data from Angi (17,857 verified window projects, updated October 2026), cross-checked against This Old House survey averages and manufacturer pricing, checked November 9, 2026. See our research method.
Windows are the home project most vulnerable to the theatrical quote. The product is sold in kitchens by dealers with laminated price-drop scripts, and the same vinyl double-hung window that an independent installer fits for $500 can be presented at $1,400 by a full-service dealer — with the difference buying the showroom, the warranty structure and the sales commission rather than a better window. The defence is knowing the market's shape before anyone sits at your table: what a window costs by type, what the frame adds, and what your neighbours' completed projects actually averaged.
Angi's dataset of 17,857 verified projects is the backbone of this guide: a $7,347 average project, most projects between $3,436 and $11,836, and a $750 per-window average. This Old House's 2026 survey lands in the same place from the other direction — its average installed double-hung window is $551 and its average vinyl window $472 — while manufacturer-channel pricing (Pella's published guide puts professionally installed vinyl at $800–$1,600 per window) shows what the dealer route costs. Three different lenses, one consistent picture: standard windows are a $300–$900 product, and everything above that is size, material or sales channel.
What the price normally includes
- The window unit itself, with double-pane insulated glass as standard
- Installation labour — insert (pocket) or full-frame, as quoted
- Exterior capping, caulking and weatherproofing of the opening
- Removal and disposal of the old window (sometimes billed separately at $50–$150)
- Interior trim refitting on full-frame work
- Manufacturer and installation warranties — get both in writing
Cost by window type (per window, installed)
| Window type | Typical range | Notes |
|---|---|---|
| Single-hung | $200–$600 | One moving sash; the budget standard |
| Double-hung | $300–$900 | The most common replacement; both sashes move and tilt |
| Sliding | $300–$1,000 | Good for wide openings; half the window opens |
| Awning | $250–$1,200 | Top-hinged; ventilates in rain |
| Casement | $350–$1,500 | Crank-opened; tightest seal of the opening styles |
| Picture | $600–$2,500 | Fixed pane; price follows size |
| Bay | $1,200–$4,500 | Three panels, structural support and trim work |
| Bow | $1,500–$6,000 | Four-plus panels; the most expensive standard type |
Type ranges are Angi's 2026 size-and-type data. Size alone moves a window as much as type does: a small bathroom window runs $200–$600, a standard bedroom window $300–$800, and a large living-room picture window $700–$1,800 before you reach custom territory at $2,500 and up.
Cost by frame material (per window, installed)
| Frame material | Typical range | Trade-offs |
|---|---|---|
| Vinyl | $200–$800 | Cheapest, low-maintenance; the default replacement frame |
| Aluminium | $250–$1,200 | Slim profiles; conducts heat unless thermally broken |
| Wood | $300–$1,500 | Best looks, most upkeep — painting and sealing are recurring costs |
| Fiberglass | $300–$2,000 | Strong, stable, paintable; the premium long-life choice |
| Composite | $500–$2,500 | Wood-look without wood maintenance, at a price |
| Steel | $750–$4,000 | Slim sightlines for modern designs; specialist product |
Frame ranges are Angi's installed-price data. Expect dealer-channel quotes to sit above these bands and independent installers within them: Pella's own guide prices its professionally installed vinyl window at $800–$1,600, roughly double the survey average for the same frame material — the clearest illustration in this market that who fits the window can matter as much as the window.
What drives the price up or down
Insert vs full-frame installation
An insert (pocket) replacement slides the new window into the existing frame — fast, cheaper, and right when the frame is sound. A full-frame replacement removes everything to the studs: it fixes rot and insulation properly, allows resizing, and costs meaningfully more in labour and trim work. Quotes are only comparable when both are pricing the same method; ask, in writing, which one you are being sold.
The glass package
Double-pane is the standard; triple-pane, laminated and low-E/argon upgrades stack cost per window. This Old House's survey averages show the gradient plainly: about $400 per window for single-pane, $529 for double-pane and $609 for triple-pane installed. In cold climates the triple-pane premium can be rational; in mild ones it is mostly a sales attachment.
Count, access and opening work
Per-window prices fall as the count rises — the crew, the setup and the disposal are already there. They rise with second-storey access (about $50–$200 more per window), with resizing an opening ($100–$500, plus carpentry at $75–$125 an hour), and with any rot or structural repair the old window was hiding.
Energy rules and the expired credit
One honest note for 2026 budgets: the federal 25C credit that used to return part of the cost of efficient windows expired for installations placed in service after December 31, 2025. Any quote that still dangles a federal window tax credit in 2026 deserves hard questions. State and utility rebates survive in places — the DSIRE database tracks them.
Ways to keep the cost down
- Replace in one project: per-window pricing drops with count, and volume orders attract real discounts.
- Choose standard sizes and vinyl or fiberglass frames; custom sizes and exotic frames are where budgets go to die.
- If the frames are sound, take the insert replacement and bank the difference.
- Get one dealer quote and one independent-installer quote for the identical spec — the gap between channels is the largest saving in this market.
- Schedule in the installers' quiet season (late autumn and winter in most regions) and ask what the off-peak price is.
- Replace only failed windows if the rest are sound — a fogged pane is a $100–$500 glass job, not a $750 window.
Frequently asked questions
How much does it cost to replace all the windows in a house?
Angi's project data puts the average whole-house job at $7,347, with most projects between $3,436 and $11,836. For a typical three-bedroom home, 10 to 12 standard double-hung windows professionally installed typically run $7,000 to $9,000 — the count and the frame material decide where you land.
What is the cheapest window replacement?
A standard-size vinyl single-hung or double-hung window, fitted as an insert into a sound existing frame. Vinyl frames start around $200 per window installed in Angi's size data, and This Old House's survey puts the average installed vinyl window at $472 — the budget end of the market by every measure.
Is it cheaper to replace all my windows at once?
Almost always, per window. Crews price setup, travel and disposal once, manufacturers and dealers discount volume orders, and the per-window labour falls as the count rises. Replacing two windows a year for six years costs meaningfully more than one 12-window project — the exception is when only a few windows have actually failed.
Can I just replace the glass instead of the whole window?
Often, yes. A fogged window is a failed seal in the insulated glass unit, and replacing just the glass or resealing runs about $100–$300 per window; a broken pane is $200–$500. If the frame itself is rotted, warped or draughty, glass-only work is money spent on a window that still fails — that is the point where full replacement takes over.
Do new windows qualify for a federal tax credit in 2026?
No. The federal Energy Efficient Home Improvement Credit (25C), which covered efficient windows, expired for property placed in service after December 31, 2025. State programmes and utility rebates still exist in some areas — check your state energy office and the DSIRE database before assuming there is nothing.
How long does window replacement take?
A professional crew fits a standard window in about one to two hours, so a whole-house project is usually scheduled across one to two days, weather permitting. Full-frame work, resizing and bay or bow installations take longer per window because framing and trim are part of the job.
