Replacing a window costs $400 to $1,200 installed for most homes in 2026, so a typical 10-window house lands between $4,500 and $12,000. Wood frames, oversized openings, and full-frame installs can push a whole-house project past $20,000. Here is how the pricing breaks down, and how to avoid the high-pressure sales tactics this industry is famous for.
Window replacement cost by frame material
Frame material sets the baseline. Vinyl dominates the market because it insulates well and costs least; fiberglass and wood buy longevity and looks at a premium.
| Frame material | Cost per window installed | 10-window home | Good to know |
|---|---|---|---|
| Vinyl | $400–$900 | $4,000–$9,000 | Best value; quality varies widely between lines |
| Composite | $500–$1,200 | $5,000–$12,000 | Wood-like look with less maintenance |
| Fiberglass | $600–$1,500 | $6,000–$15,000 | Strong, stable, paintable; long service life |
| Aluminum | $500–$1,200 | $5,000–$12,000 | Slim frames; thermally broken versions insulate better |
| Wood / wood-clad | $800–$2,000 | $8,000–$20,000 | The premium look; needs upkeep unless clad |

Cost by window style
| Window style | Typical installed cost |
|---|---|
| Double-hung | $400–$1,100 |
| Casement (crank-out) | $500–$1,400 |
| Sliding | $450–$1,300 |
| Picture (fixed) | $400–$1,200 |
| Bay or bow | $1,800–$4,500+ |
| Egress (basement) | $1,500–$5,000+ with well and excavation |
Style pricing overlaps heavily with frame material; a wood casement costs more than a vinyl one.
Insert vs. full-frame replacement
This choice moves your budget more than most homeowners expect. An insert replacement slides a new window into your existing frame, keeping interior and exterior trim intact. It is faster and cheaper, and it is the right call when the existing frames are square and rot-free.
A full-frame replacement strips the opening to the studs: new frame, new flashing, new insulation around the opening. It costs roughly 30–60% more per window, but it is the only honest fix for rot, water intrusion, or badly out-of-square openings, and it slightly increases glass area. If an installer quotes inserts without inspecting the existing frames closely, that is a shortcut you will pay for later.
What drives the price up or down
- Glass package. Double-pane low-E is standard. Triple-pane, laminated, or impact-rated glass adds $100–$600+ per window and matters most in extreme climates and hurricane zones.
- Size and floor. Oversized openings and second- or third-story work add labor and staging.
- How many at once. Whole-house jobs earn a meaningfully lower per-window price than replacing two or three.
- Hidden damage. Rot around the opening discovered during removal is the common surprise; ask for a unit price for frame repairs up front.
- Permits and code. Bedroom windows must meet egress sizes, and some regions require tempered or impact-rated glass in specific locations. Permits typically run $50–$300.
- Brand tier. The same house can be quoted at $6,000 or $30,000 depending on whether it is builder-grade vinyl or a premium national brand sold in-home. Both extremes deserve skepticism.
Reading the sticker: the two numbers that matter
Every certified window carries a label with performance ratings, and two of them do most of the work. U-factor measures how well the window keeps heat in; lower is better, and quality double-pane units commonly land around 0.25–0.30. Solar heat gain coefficient (SHGC) measures how much sun heat comes through; in hot climates you want it low, in cold climates a bit higher can help with winter warmth. When two quotes claim “energy-efficient windows,” comparing these two numbers, not the brochure adjectives, tells you whether you are actually being offered the same class of product.
Ways to save without buying twice
- Replace in batches, not onesies. Doing the whole house, or at least a full side, gets better per-window pricing than spreading singles over years.
- Skip features you will not feel. Triple-pane in a mild climate, or premium interior wood finishes in a rental, rarely pay back.
- Compare a local quote against national in-home brands. Well-reviewed regional installers often quote the same performance class for dramatically less than a three-hour in-home presentation.
- Look into energy-efficiency incentives. Federal or local programs periodically offer credits for qualifying windows; check current rules before you order, and do not let a salesperson do that math for you.
- Repair when repair is honest. A failed sash balance, worn weatherstripping, or a single fogged pane can often be fixed for $150–$500, and a good pro will say so.
What a good window quote should include
- Brand, series, frame material, and glass package for every window, not just “vinyl windows”
- Insert or full-frame, stated per opening
- Count and measurements taken on site
- Exterior finishing: capping, flashing, caulking, and interior trim scope
- Disposal of old windows, permits, and cleanup
- A unit price for rot or frame repairs found during removal
- Both warranties in writing: the manufacturer’s on the window and the installer’s on the labor
Red flags when hiring a window company
- The three-hour in-home pitch ending in a “tonight only” price. Real prices survive the night.
- A quote 50–70% “off” a list price no one ever pays.
- No license or insurance you can verify, or a crew of unnamed subcontractors with no accountability.
- Insert quotes with no frame inspection when your frames show staining, softness, or peeling paint.
- Full payment up front. Custom windows justify a deposit, commonly a third, not the whole job.
Window sales is one of the most aggressive corners of home improvement, which is exactly why we vet first. Installers matched through VettedQuote have already passed license, insurance, and complaint-history checks, and the ones who fail never get your number.
How long does window replacement take?
Installation itself is fast: an experienced crew replaces an insert window in 30–60 minutes and does a typical whole house in one to three days. Full-frame work runs closer to half a day per opening. The real wait is manufacturing: custom-measured windows commonly take 3 to 8 weeks from order to install, so line up quotes before the season you want them in.
Frequently asked questions
How much does it cost to replace all the windows in a house?
A typical 10-window home runs $4,500 to $12,000 with vinyl inserts. Fiberglass or wood frames, full-frame installation, or oversized openings can push a whole-house project to $15,000–$25,000 or beyond.
Is it cheaper to replace all windows at once?
Per window, yes. Installers price whole-house jobs with lower per-unit labor, and you pay mobilization once. If budget forces phasing, do full sides of the house at a time so trim and sight lines stay consistent.
Do new windows really lower energy bills?
They help, but modestly: windows are one piece of the home’s envelope alongside insulation and air sealing. Replace windows when they are failing, rotting, fogging, or miserable to operate, and treat energy savings as a bonus rather than the payback story a salesperson may pitch.
What time of year is best to replace windows?
Crews install year-round, working one opening at a time to limit heat or cold exposure. Late fall and winter often bring better pricing and shorter lead times; spring and summer are peak season.
Should I repair or replace a foggy window?
Fog between panes means the insulated glass seal failed. On an otherwise sound, newer window, replacing just the glass unit for $200–$500 is often sensible. On older windows with worn hardware and drafty frames, that money is better applied to replacement.
