Window replacement costs $300–$1,500 per window installed in 2026, with most homeowners paying $500–$900 per window for a standard mid-range vinyl unit. Whole-house replacement (10–20 windows) typically runs $5,000–$25,000 depending on size, frame material, and glass package. The biggest cost drivers are frame material (vinyl, wood, fiberglass, aluminum), window size and style, and whether the install is a pocket replacement or a full frame-out. This guide breaks down per-window and whole-house costs, the difference between vinyl, wood, and fiberglass tiers, and where homeowners save (and where cheap windows quietly cost more long-term).
| Service | Typical cost |
|---|---|
| Vinyl window (standard size, installed) | $300–$900 |
| Wood window (clad or solid, installed) | $700–$1,500 |
| Fiberglass window (installed) | $700–$1,400 |
| Aluminum window (installed) | $400–$1,200 |
| Composite window (installed) | $600–$1,300 |
| Bay or bow window (installed) | $1,500–$4,500 |
| Picture / fixed window (installed) | $300–$800 |
| Whole-house replacement (10 windows) | $5,000–$15,000 |
| Whole-house replacement (20 windows) | $10,000–$25,000+ |
| Full frame-out (vs. pocket install) add-on | +$200–$500/window |
Quoted prices typically include the window unit, basic flashing and trim, and labor. Custom sizes, triple-pane glass upgrades, exterior trim repair, and interior trim painting are usually billed separately.
Vinyl is the value tier — durable, low-maintenance, and the cheapest at $300–$900 per window installed. Wood is the premium look but needs paint or stain every 3–7 years; clad-wood (aluminum or vinyl exterior over wood interior) splits the difference at $700–$1,500. Fiberglass is the sleeper pick — narrow sightlines, won't warp, paintable, and lasts 30+ years at $700–$1,400. Aluminum is cheap and strong but conducts cold, so it's more common in mild climates and commercial buildings.
Picture windows (fixed, no opening) are the cheapest because there's no operating hardware. Double-hung and casement windows are mid-range. Bay and bow windows are the most expensive ($1,500–$4,500 each) because they're multiple units, structural, and require custom flashing. Larger-than-standard windows often need custom-order pricing — budget 30–60% extra for any non-stock size.
Single-pane glass is rare in new windows and only seen in mild climates. Double-pane with low-E coating and argon fill is the standard package — included in most $500–$900 vinyl pricing. Triple-pane with krypton fill cuts heat loss further and is worth considering in cold climates (zone 6+) — adds $100–$250 per window. Tempered glass (required by code near floors and doors) and obscure glass (bathrooms) add $50–$150 per window.
A pocket (insert) replacement reuses the existing frame and slips a new window inside — fastest, cheapest, and the right call when the frame is sound. A full frame-out (rip the entire window and frame) adds $200–$500 per window in labor plus exterior siding/flashing repair, but it's necessary if the frame is rotted, the rough opening is wrong size, or you're upgrading from old aluminum to wood with a different jamb depth.
If the old frames hide rot, water damage, or settled rough openings, the install bill grows: rotted sill replacement runs $100–$300 per window, exterior trim repair $50–$200, and a structurally compromised header repair can add $300–$1,000. Reputable installers will inspect a few representative windows during the quote and flag risks; a too-good-to-be-true bid often skips the discovery step.
High-cost metros (NYC, SF, Boston, Seattle) run 30–50% above national medians on labor; high-end remodeling markets (Aspen, Hamptons, etc.) higher still. Crew availability also matters — peak seasons (spring, early fall) often have 4–8 week lead times and full-rate pricing; off-season (mid-summer, deep winter) sometimes offers 5–15% discounts and faster scheduling. Energy-efficiency rebates and federal tax credits (up to $600 in 2026 for ENERGY STAR-certified windows) can offset 5–15% of project cost.

Vinyl windows typically last 20–30 years before seals fail or frames warp — high-quality vinyl with welded corners can hit the 30-year mark; cheap vinyl rarely makes it past 15. Wood windows last 30+ years with regular maintenance (paint or stain every 3–7 years, prompt repair of any rotted spots). Fiberglass is the longevity champion at 40–50+ years. The seal between glass panes is the most common failure mode — if you see fog between the panes, the seal has failed and the glass unit needs replacing ($150–$400 per sash) even if the frame is fine.
Replacing all at once usually costs less per window because the crew is set up, the dumpster is rented, and the discount tier kicks in for larger orders (most installers offer 5–15% off for whole-house jobs). Phasing makes sense when budget is tight or when only some windows are failing — start with the worst-condition or worst-performing windows (single-pane, fogged, or won't close right) and do the others over 1–3 years. Phasing the same brand and style keeps the house looking consistent.
Not necessarily — high-quality vinyl from a reputable manufacturer (Andersen, Pella, Marvin, Milgard, Provia) performs very well on energy efficiency and longevity, and costs half what wood costs. The downsides: vinyl has thicker frames (less glass area), can't be painted, and the cheap end of the market is genuinely poor (sticking sashes, failed seals, brittle frames after 10 years). For a starter home or rental, mid-range vinyl is a fine call. For a forever home or higher-end remodel, fiberglass or clad-wood is usually worth the upcharge.
Yes, but the payback depends on what you're replacing. Replacing single-pane or aluminum-frame windows in a cold climate can cut heating bills 10–25% and pay back in 8–15 years. Replacing already-decent double-pane windows from the 1990s with new ones saves much less — often 5–10%, with payback periods of 20+ years. Energy savings are real but window replacement is rarely justified by energy savings alone; comfort, noise reduction, curb appeal, and operating-window functionality usually drive the decision.
A pocket (insert) replacement removes only the operating sash and old jamb liners, then slides a new window into the existing frame — fastest, cleanest, and works when the old frame is sound. A full frame-out tears out the entire window and frame down to the rough opening — slower, costs $200–$500 more per window, and exposes any hidden rot or water damage that needs repair. You need a full frame-out if the old frame is rotted, you're changing the rough opening size, or you're switching to a window with a different jamb depth (e.g., aluminum to wood).
Routine wear-and-tear replacement is not covered. Insurance typically covers window replacement only when damage is from a covered event — falling tree, hail, vandalism, broken pipe flooding the wall. Even then, the deductible may exceed the per-window cost. For ENERGY STAR-certified replacement windows, the federal Energy Efficient Home Improvement Credit allows up to $600 in tax credit per year (30% of cost up to that cap) — keep manufacturer NFRC labels and receipts. Some states and utilities offer additional rebates for high-efficiency windows.
Get 3 quotes for any whole-house job; 2 for partial. Make sure each quote specifies: window manufacturer and model, frame material, glass package (panes, gas fill, low-E coating, U-factor and SHGC numbers from the NFRC label), pocket vs. full frame-out, who handles old window disposal, exterior and interior trim work, paint or stain finish, and warranty (look for 20-year or lifetime on the frame and glass seal, 10+ years on hardware). Beware salespeople who pressure same-day decisions, won't leave the bid in writing, or quote a single bottom-line number without itemized line items — those are red flags for both quality and pricing.
