Window Replacement Cost Guide 2026
Advertisement
Replacing windows costs $450–$1,500 per window installed, and $4,500–$15,000 for a full house — with most US homeowners landing at $7,000–$12,000. This guide breaks down per-window prices by type and frame material, full-house budgets, insert vs. full-frame installation, energy ROI, and the quote red flags that separate honest contractors from salespeople.
Window replacement cost per window (2026)
| Window type | Vinyl | Aluminum-clad wood | Fiberglass | Wood |
|---|---|---|---|---|
| Double-hung | $450–$800 | $550–$1,000 | $650–$1,100 | $800–$1,500 |
| Casement | $500–$900 | $600–$1,100 | $700–$1,200 | $850–$1,600 |
| Sliding | $450–$850 | $550–$1,000 | $650–$1,100 | $800–$1,400 |
| Picture (fixed) | $400–$700 | $500–$900 | $550–$1,000 | $600–$1,200 |
| Bay / bow | $2,500–$4,000 | $3,000–$4,500 | $3,200–$4,800 | $3,500–$5,000+ |
All figures are October 2026 US installed prices (±25%) at national-average labor with insert installation. Full-frame tear-out adds roughly $250 per window to the labor line. The cheapest realistic job — a vinyl double-hung, insert install, standard glass — lands around $450–$650 per window; the same opening in wood with full-frame tear-out runs $1,000–$1,800. That 3× spread within one window opening is why "cost per window" quotes without material and method specified are meaningless. For your exact numbers, use our window replacement cost calculator.
Full-house window replacement cost
| House size (windows) | Vinyl, insert | Mid-range mix | Premium / full-frame |
|---|---|---|---|
| Small (6–8 windows) | $3,000–$5,500 | $5,000–$9,000 | $9,000–$14,000 |
| Typical (10–12 windows) | $4,500–$8,000 | $8,000–$14,000 | $14,000–$22,000 |
| Large (15–20 windows) | $7,000–$12,000 | $12,000–$20,000 | $20,000–$32,000 |
| With 1–2 bay/bow windows | Add $2,500–$5,000 per bay/bow to any band above | ||
The "typical" 10-window vinyl job at $4,500–$8,000 is the statistical center of the US market — most quotes you'll collect will land here. Volume discounts matter: contractors routinely shave 10–20% off full-house jobs versus per-window pricing, because the crew mobilizes once and the distributor order hits volume tiers. If your quote for 10 vinyl double-hungs comes back over $9,000 with insert installation, you're either in a very high-cost metro or being upsold — get two more quotes.
Frame materials compared
| Vinyl | Fiberglass | Aluminum-clad wood | Wood | |
|---|---|---|---|---|
| Installed cost (double-hung) | $450–$800 | $650–$1,100 | $550–$1,000 | $800–$1,500 |
| Lifespan | 20–30 yrs | 30–40 yrs | 30+ yrs | 30+ yrs (maintained) |
| Maintenance | None | Paintable, rarely needed | None outside | Repaint every 5–7 yrs |
| Energy | Good | Excellent (low expansion) | Good | Good |
| Looks | Plain, chunky frames | Slimmer, paintable | Wood interior | Premium wood interior |
| Best for | Budget full-house jobs | Buy-it-for-life | Curb appeal + low upkeep | Historic / high-end homes |
The honest take: vinyl wins on value and has for 30 years — it's why roughly two-thirds of US replacement windows are vinyl. Fiberglass is the engineer's pick: it expands and contracts at nearly the same rate as glass, so seals last longer, and the frames are slimmer and stronger. Wood is the look pick, full stop — nothing matches a real wood interior, but budget the repainting or it becomes the rot pick. Aluminum-clad wood is the compromise most architects actually specify: wood inside where you see it, maintenance-free aluminum outside where the weather hits. Manufacturer lines worth comparing: Andersen (Fibrex composite, wood), Pella (wood, fiberglass, vinyl), and the ENERGY STAR window finder for certified models by climate zone.
Insert vs. full-frame installation
Insert (pocket) replacement — $150–$250/window labor — fits the new window into the existing frame. The trim, casing and siding stay put; a crew does 10–15 a day. Right for most homes where frames are square and rot-free.
Full-frame (tear-out) replacement — $350–$500/window labor — strips everything to the rough opening and installs a complete new window with fresh flashing and insulation. Required for rot, water damage, resizing, or style changes — and the only way to fix flashing the original builder botched.
On a 10-window job, the method choice alone swings the labor bill by ~$2,500. Be suspicious of any salesperson who prices full-frame on all windows without inspecting a single frame for rot — and equally suspicious of an insert quote on 40-year-old wood windows nobody looked at closely. The $150/window rot allowance in our calculator exists because the truth is usually found mid-job.
Labor and the hidden lines
Window units are nationally priced; installation labor is intensely local. Rural markets run ~15% below national, West Coast and Northeast metros ~20% above, and high-cost cities (Bay Area, NYC, Boston) 30–40% above. Our labor-by-ZIP guide explains the BLS-based multiplier behind the calculator's local adjustment.
- Disposal: $30–$75 per window for haul-away. Old windows are bulky; landfill fees are real.
- Interior trim repair: $50–$150 per window when full-frame work disturbs casing and drywall returns.
- Lead-safe practices: EPA RRP rules require certified lead-safe work in pre-1978 homes — add $50–$150 per window. A contractor who doesn't mention this in an older home is either ignorant or cutting corners.
- Rot repair: $100–$300 per window when sills or jambs are soft. Found on inspection or mid-job.
- Permits: $0 for like-for-like inserts in most jurisdictions; $100–$300 when openings change or you're in a historic district.
Energy efficiency and payback
Every quality replacement window today is double-pane with low-E coating and argon gas fill — an enormous upgrade over single-pane aluminum windows, which are essentially holes with glass in them. ENERGY STAR estimates that replacing single-pane windows with ENERGY STAR models saves roughly $100–$580 a year on energy bills, depending on climate and house size. If your current windows are already double-pane and functioning, the energy payback stretches to decades — you're buying comfort, quiet, and looks, not utility savings.
Read the NFRC label, not the brochure: U-factor ≤0.30 for cold climates (lower = less heat loss), SHGC matched to your climate (low in the South to block sun, higher in the North to welcome winter sun). Triple-pane (~$140/window extra) pays back in heating-dominated climates and is a luxury elsewhere. And one free efficiency upgrade: air-seal the window-to-framing gap with low-expansion foam during install — installers who skip this leave the draft you paid to eliminate.
ROI: what new windows do for home value
Mid-range vinyl window replacement recoups roughly 65–70% of its cost at resale — among the better returns for exterior projects, per Remodeling's Cost vs. Value data. The return isn't just the appraisal math: new windows photograph well, eliminate the "deferred maintenance" smell buyers detect instantly, and remove a negotiation lever. Where the ROI breaks down is over-improvement — $1,500 wood windows in a $200,000 neighborhood don't come back, but $600 vinyl windows in the same neighborhood do. Match the window to the house, not to the showroom.
Replace vs. repair: the decision rule
| Symptom | Repair | Replace |
|---|---|---|
| Fog between the panes | Defogging services exist but are temporary | Replace — the seal has failed |
| Drafts around a sound window | Weatherstripping + caulk ($20–$50/window) | — |
| Broken latch or balance | Hardware replacement ($50–$150) | — |
| Rotted sill or jamb | Epoxy/splice if localized | Replace if widespread (full-frame) |
| Single-pane glass, cold climate | Storm windows ($100–$300) | Replace for real efficiency |
| Hard to open / painted shut | Free up + new balances | Replace if frames are distorted |
The rule of thumb: if a repair costs more than a third of replacement and the window is over 20 years old, replace it. Fogged glass is the clearest replace signal — a failed seal means the insulating gas is gone, and the window is now performing like a single pane with extra steps.
Quote red flags
- Lump-sum quote, no per-window breakdown. Honest contractors itemize units, labor, disposal, permits. Padding hides in lump sums.
- "Sign today" discounts. Real pricing doesn't expire at midnight. The high-pressure close is the oldest trick in home improvement.
- Full-frame on every window, sight unseen. Without checking for rot, this is upselling, not diagnosing.
- No lead-safe mention in a pre-1978 home. EPA RRP certification is federal law, not a nice-to-have.
- Deposit over 30%. 10–20% to order custom windows is normal; half up front is a risk you don't need.
- No NFRC labels discussed. If the salesperson can't talk U-factor and SHGC, they're selling, not advising.
Get three itemized quotes. Compare the per-window unit price and per-window labor lines separately — the cheapest total is often just the cheapest labor, and labor is where quality lives or dies. The Journal of Light Construction and NAHB cost surveys are useful reality checks against outlier bids.
Window terms worth knowing
The vocabulary that keeps you from overpaying:
- Double-hung — both sashes slide; the classic US window. Single-hung — only the bottom sash moves; slightly cheaper.
- Casement — hinged on the side, cranks open. Best ventilation and tightest seal of operable types.
- U-factor — whole-window heat loss rate; lower is better. ≤0.30 is the cold-climate benchmark.
- SHGC — solar heat gain coefficient, 0–1. Lower blocks more sun (good in the South).
- Low-E coating — invisible metallic layer reflecting heat back where it belongs. Standard on quality glass.
- Argon / krypton fill — inert gas between panes slowing heat transfer. Argon is standard; krypton is the premium upgrade.
- Insert / pocket — replacement inside the existing frame. Full-frame — complete tear-out to the studs.
- Sash, jamb, sill — the moving glass frame, the side frame, the bottom piece (most rot-prone).
- Egress — code-minimum escape size for bedroom windows. Costs more due to size rules.
- NFRC label — certified U-factor/SHGC sticker. The only performance numbers you should trust.
- Muntins / grilles — dividers faking divided lites. Between-glass is maintenance-free; true divided lites cost 2–3×.
Window replacement FAQs
How much does it cost to replace all the windows in a house?
For a typical 10-window house: $4,500–$8,000 with vinyl double-hung windows and insert installation, $8,000–$15,000 with wood or fiberglass frames, and $20,000+ for large homes with bay windows or full-frame tear-outs. Most US homeowners land in the $7,000–$12,000 band for a full-house job.
What window material is the best value?
Vinyl is the best value: $450–$800 per window installed, 20–30 year lifespan, zero maintenance. Fiberglass costs 45% more but lasts 30–40 years and can be painted. Wood is the premium pick for looks ($800–$1,500) but needs repainting every 5–7 years. Aluminum-clad wood splits the difference.
How much value do new windows add to a home?
Mid-range vinyl window replacement recoups roughly 65–70% of its cost at resale — one of the stronger returns among exterior projects. Beyond resale, new windows cut drafts, reduce outside noise, and lower energy bills by roughly $100–$580 a year when replacing single-pane glass.
Should I replace windows one at a time or all together?
All together is almost always cheaper: contractors discount full-house jobs 10–20% on both units and labor because the crew mobilizes once. One-at-a-time replacement makes sense only when a single window fails (broken seal, cracked glass) and the rest are fine.
What are red flags in a window replacement quote?
Lump-sum quotes with no per-window breakdown, pressure to sign today for a discount, full-frame pricing on every window without checking for rot, no mention of lead-safe practices in a pre-1978 home, and a deposit over 30%. Get three itemized quotes and compare per-window unit and labor lines.
How long does window replacement take?
A crew installs 10–15 insert windows per day — most full-house jobs finish in 1–2 days. Full-frame tear-outs run slower, roughly 6–10 per day. Lead time is the real wait: custom-ordered windows typically take 4–8 weeks from measurement to installation day.
Can I replace windows myself to save money?
DIY insert replacement can save $150–$250 per window in labor, but the risks are real: a poorly flashed window leaks into the wall cavity and rots framing you can't see. Most manufacturers also void the warranty on owner-installed units. DIY makes sense for a single ground-floor window; leave a full house to a pro crew.
Do I need a permit to replace windows?
Usually not for insert (pocket) replacements that keep the same opening size. Full-frame replacements that alter the opening size, or any window work in a historic district, typically need a permit ($100–$300). Egress windows in bedrooms must meet minimum opening sizes by code regardless of permit status.
