Most homeowners pay $450–$1,200 per window installed, or about $750–$800 on average. Most whole projects cost $3,400–$11,800 (average about $7,350); a typical 3-bedroom home with 10–12 windows runs $7,000–$9,000, and a large two-story house $12,000–$24,000 (Angi and Fixr data, as of October 2026).

Replacing windows makes sense when frames are rotting, seals have failed (fog between panes), or drafts are driving up heating and cooling bills. The biggest price swings come from the frame material, the glass package and whether the installer can use an insert or has to go full-frame.
Below you'll find average costs per window and per project, a line-item breakdown, and how to keep the bill down. If only the glass is broken or fogged, read our window glass replacement cost guide first — it is usually far cheaper.
Average cost
Installed prices for standard-size windows, national averages as of October 2026:
| Scenario | Typical range | Notes |
|---|---|---|
| Single window, vinyl double-hung (insert) | $450–$900 | Frame in good shape; one-day job |
| Typical project (all sizes) | $3,400–$11,800 | Angi's range for most projects; average about $7,350 |
| 10–12 windows, typical 3-bedroom home | $7,000–$9,000 | Mid-range vinyl or composite |
| Whole house, 15–30 windows, two stories | $12,000–$24,000 | Full-frame where needed, upper-floor access |
| Premium wood, fiberglass or bay/bow units | $1,000–$8,000 per window | Custom sizes, triple-pane glass, interior finishing |
Cost per window by frame material
| Frame material | Installed cost per window | Good to know |
|---|---|---|
| Vinyl | $350–$900 | Best value; low maintenance |
| Aluminum | $200–$800 | Slim frames; less insulating |
| Wood | $600–$2,000 | Classic look; needs painting |
| Composite | $300–$1,200 | Wood look, vinyl-like upkeep |
| Fiberglass | $500–$1,500 | Very stable and durable |
Cost per window by style
| Window style | Installed cost per window |
|---|---|
| Single-hung | $250–$700 |
| Double-hung | $300–$1,000 |
| Casement | $400–$1,200 |
| Sliding | $700–$1,500 |
| Picture | $300–$1,600 |
| Bay | $900–$4,500 |

Cost breakdown: materials, labor, permits and extras
Line-item estimate for replacing 10 mid-size double-hung vinyl windows with double-pane low-E glass (mostly insert installation). Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Windows (materials) | $3,000–$6,500 | 10 vinyl units, double-pane low-E, standard sizes |
| Labor | $1,000–$3,000 | Removal of old sashes, install, insulation, sealing |
| Trim, capping and finishing | $200–$800 | Exterior aluminum capping, interior stops |
| Permits & inspections | $50–$300 | Required in many towns, especially for full-frame or egress |
| Disposal & cleanup | $0–$300 | Often included; some installers bill $55–$65/hour |
| Contingency (about 10%) | $400–$1,000 | Rotten sills or framing found during removal |
| Estimated total | $4,650–$12,000 | Before any discounts or rebates |
Labor is typically around 30% of the total; materials drive most of the difference between a basic and a premium project.
What affects the price
- Number and size of windows. Price scales almost linearly with the number of windows, and large or custom-size units cost more than stock sizes. Ordering many windows at once can earn a volume discount.
- Frame material (vinyl, wood, fiberglass, aluminum). Vinyl is the cheapest at roughly $350–$900 installed; wood and fiberglass run $500–$2,000 per window.
- Glass package (double or triple pane, low-E coatings). Double-pane low-E is the standard; triple-pane can double the cost of a unit ($1,000–$4,000), and tempered or laminated safety glass adds $100–$800.
- Style (double-hung, casement, slider, bay). Double-hung and single-hung are cheapest; casement, sliding and picture windows cost more, and bay or bow windows run $900–$8,000 because of their size and structure.
- Insert or full-frame installation. An insert (retrofit) keeps the existing frame and adds only about $100–$300 in labor per window; full-frame replacement costs $180–$1,500 more per window but fixes rotted frames and improves air sealing.
- Repair of rot, trim and finishing. Rotten sills, damaged sheathing or new interior trim can add a few hundred to a few thousand dollars, and second-story windows cost more to reach.
- Permits and local labor rates. Permits usually cost $50–$300. Labor runs about $100–$300 per standard window but can top $600 for upper floors or structural changes, and is higher in big metro areas.
Ways to save
- Get at least three written quotes that list the same brand, series, glass package and installation method so you can compare like for like.
- Choose insert installation when your frames are square and rot-free; it saves several hundred dollars per window.
- Replace windows in batches: crews charge less per unit when they do a whole elevation or the whole house in one visit.
- Pick ENERGY STAR double-pane low-E vinyl instead of triple-pane unless you live in a very cold climate; the payback on triple-pane is slow.
- Ask your utility and state energy office about window rebates. The federal 25C energy-efficiency tax credit ended for windows installed after December 31, 2025, so don't count on it for a 2026 project.
- Schedule in late fall or winter, when many installers have more availability and may discount.
Related questions people ask
What is the average cost of window replacement?
The average replacement window costs about $750–$800 installed. Angi reports an average project total of about $7,350, with most homeowners paying between $3,400 and $11,800.
How much does window replacement cost per window?
Expect $450–$1,200 per window for standard sizes. Basic vinyl inserts can come in under $450, while large custom, wood or bay windows can exceed $2,000 each.
How much does vinyl window replacement cost?
Vinyl replacement windows cost about $350–$900 each installed. For a 10-window home, budget roughly $4,000–$9,000 including labor and trim.
What does full-frame window replacement cost?
Full-frame replacement runs about $180–$1,500 more per window than an insert, because the installer removes the old frame, sill and trim down to the rough opening. It's the right choice when frames are rotten or you want a larger glass area.
What is the cost of replacement windows alone?
Replacement window units cost roughly $200–$1,000+ before labor, depending on material and glass. Installation typically adds $100–$300 per standard window.
How to get an accurate quote
Ask at least three licensed, insured installers for written, itemized quotes. Give each the same information:
- The number of windows, their rough sizes (width × height) and which floor each is on.
- The style you want for each opening and the frame material, plus the glass package (double or triple pane, low-E, tempered).
- Whether you want insert or full-frame installation, and any known rot or water damage.
- Ask what is included: removal and disposal, interior trim, exterior capping, permits, and the labor and product warranties.
FAQ
How long does window replacement take?
A crew can often replace several insert windows in a single day, so a typical 10-window job takes 1–3 days. Custom windows usually have to be ordered weeks in advance, so the overall timeline is longer than the installation itself.
Is replacing windows worth the money?
Usually yes if your windows are drafty, fogged or rotting. New windows recover a good share of their cost at resale and lower energy bills, though the savings alone rarely pay back the full price quickly.
Do I need a permit to replace windows?
It depends on your city. Same-size insert replacements often don't need one, but full-frame installs, enlarged openings and egress windows usually do. Permits typically cost $50–$300.
