How Much Does Window Replacement Cost?
Real 2026 pricing for replacement windows - by type (double-hung, casement, bay), by frame (vinyl, wood, fiberglass), and by glass package. What to pay per window, when insert beats full-frame, and the one glass upgrade that pays back in a few years.
Last updated: July 2026
Pre-1978 home? Lead-safe removal required.If your house was built before 1978, federal law (RRP rule) requires the contractor to be RRP-certified and use lead containment on window replacement. A contractor who doesn't ask your home's age is cutting a federal requirement. Also: bedroom windows must meet egress escape minimums - replacing a bedroom window with a smaller unit fails inspection and is a fire hazard.
The Short Answer
A replacement window costs $300 to $2,500 installed in 2026, with the national average around $600-$1,000 per window. A standard double-hung vinyl window runs $300-$700- that's the Angi baseline most quotes start from. The biggest cost driver is window type (a single-hung is $200-$450; a bay window is $1,000-$3,000+), followed by frame material and glass package. Insert replacement costs 25% less than full-frame but only works when the old frame is sound. Low-e glass (+15%) pays back in a few years; triple-pane (+40%) only earns its premium in cold climates. For a full house (10-15 windows), budget $4,000-$12,000 for standard vinyl and $15,000-$30,000+ for premium.

Window Replacement Cost by Type (2026)
Window type is the single biggest cost driver after count. Here's what each common replacement window costs installed, with the Angi-cited vinyl double-hung baseline ($300-$700) as the reference point.
| Window Type | Cost/Window (Installed) | Best For |
|---|---|---|
| Single-hung | $200-$450 | Operable - Bottom sash slides up, top sash fixed. |
| Double-hung | $300-$700 | Operable - Both sashes slide vertically and tilt in for cleaning. |
| Casement | $400-$1,000 | Operable - Hinged on the side, cranks out like a door. |
| Sliding (glider) | $350-$900 | Operable - One or both sashes slide horizontally on a track. |
| Awning | $400-$900 | Operable - Hinged at the top, swings out at the bottom. |
| Picture (fixed) | $500-$1,500 | Fixed (no ventilation) - Large fixed pane, no moving parts. |
| Bay / bow (projected) | $1000-$3,000 | Operable - Bay (3-unit angular projection) or bow (4-6 unit curved projection) windows extend outside the wall line. |

Window Cost by Frame Material (2026)
Frame material swings the price 1.7x - and it also drives lifespan, maintenance, and energy efficiency. Vinyl is the baseline; everything else is measured against it.
| Frame Material | Cost vs Vinyl | Lifespan | Notes |
|---|---|---|---|
| Vinyl | 1.0x (baseline) | 20-30 | Baseline - cheapest, lowest maintenance, good insulation. Won't rot or need painting. The downside: it expands and contracts with temperature, so cheap vinyl warps over time. Buy a mid-range vinyl (not builder-grade) and it'll outlast the warranty. |
| Aluminum | 0.85x | 15-25 | Cheapest up front but poor insulation - metal conducts heat and cold, so aluminum windows lose more energy than any other frame. Best for mild climates, garages, or outbuildings where efficiency doesn't matter. Rarely the right choice for a heated home in a cold climate. |
| Fiberglass | 1.4x | 30-50 | Premium option - strongest frame, won't warp, expand, or rot. Can be painted. Best energy efficiency after wood. Costs 40% more than vinyl but lasts longer and outperforms it. The contractor-preferred choice for high-end replacements that won't be touched again for 40 years. |
| Wood | 1.5x | 30+ (with maintenance) | Most expensive and highest maintenance - requires painting or cladding every 5-8 years. In return: best insulation, classic look, and the only frame that adds resale value on its own. Wood-clad (wood interior, vinyl or aluminum exterior) gives the look with less maintenance at the same price. |
On a $500 vinyl double-hung baseline: aluminum runs ~$425, fiberglass ~$700, wood ~$750 per window. Wood-clad (wood interior, vinyl or aluminum exterior) gives the wood look with less maintenance at the same price.
Window Cost by Glass Package (2026)
The glass package is a 2x range - and the one upgrade with a measurable payback. Double-pane is the modern baseline; single-pane is largely phased out of code-compliant replacement.
| Glass Package | Cost vs Double-Pane | Payback |
|---|---|---|
| Single-pane | 0.7x | One layer of glass. Cheapest but barely insulates - single-pane windows lose up to 50% more heat than double-pane. Largely phased out of code-compliant residential replacement; mostly found in garages, sheds, and mild climates. Don't install in a heated home if you can help it. |
| Double-pane (insulated) | 1.0x (baseline) | Two panes with an insulating gas (argon or krypton) between them. The modern baseline - code-required in most climates. Cuts heat loss roughly in half vs single-pane. The right default for almost every replacement project. |
| Double-pane + Low-E coating | 1.15x | Double-pane with a low-emissivity metallic coating that reflects heat back to its source. Keeps heat in during winter, out during summer. Adds ~15% to the window but pays back in energy savings within a few years. Effectively the standard upgrade in hot and cold climates. |
| Triple-pane | 1.4x | Three panes, two gas-filled gaps. Best insulation and soundproofing, 30-50% more than double-pane (we use +40%). Worth it in extreme cold climates (Mountain, Northern Midwest) or on noisy streets. In mild climates the payback period can exceed the window's lifespan - skip it there. |
On a $500 double-pane baseline: single-pane runs ~$350 (rarely code-compliant), low-e ~$575, triple-pane ~$700. Low-e pays back in a few years; triple-pane only in extreme cold or noisy sites.
Insert vs Full-Frame Replacement: Which Do You Need?
The installation method is a 25% cost swing and the single most common quoting trap in window replacement. A contractor quoting insert without inspecting the frame is burying hidden rot. Use this matrix before you accept a quote.
| Factor | Insert (pocket) | Full-frame |
|---|---|---|
| Cost vs baseline | 1.0x (cheapest) | 1.25x (+25%) |
| What stays | Existing frame and trim | Nothing - opening exposed to rough framing |
| When to use | Frame is square, plumb, rot-free, same size | Frame rotted, out of square, or resizing |
| Hidden rot | Not addressed - covered up | Exposed and fixed before new window goes in |
| Trim work | Minimal - existing trim reused | New interior and exterior trim required |
| Time per window | 30-60 minutes | 2-4 hours |
The rule of thumb: if the existing frame has any visible water damage, soft wood, or the sash doesn't sit level, budget for full-frame. The extra 25% fixes the underlying problem instead of covering it up. If the frame is sound and you're keeping the same size, insert replacement is the smarter buy. Always require an in-person frame inspection before a contractor commits to insert.
Basement & Egress Window Replacement: The Foundation-Cutting Premium
Basement windows are a different animal. A standard basement slider or awning swaps like any other window ($300-$700). But if the basement window serves a bedroom, code requires it to meet egress - an escape opening big enough to climb out of. That turns a simple swap into a foundation-cutting project.
Standard basement window: $300-$700 installed. Slider or awning style, small opening, no egress requirement (storage, utility rooms).
Egress window (basement bedroom): $2,500-$5,500+ installed. Requires cutting the foundation wall to enlarge the opening, installing a window well ($500-$1,500), and meeting IRC egress minimums: 5.7 sq ft clear open area, 24-inch minimum height, 20-inch minimum width.
Egress window well: $500-$1,500. Required for below-grade egress windows. Includes excavation, the well itself, a ladder (if over 44" deep), and drainage to prevent water pooling.
Watch for: A contractor who replaces a basement bedroom window with a smaller unit without checking egress is creating a code violation and a fire-safety failure. If the existing opening already meets egress, a same-size replacement is straightforward. If it doesn't, you're in foundation-cut territory - get a quote that breaks out the concrete cutting, well, and drainage separately.
Cost to Replace All Windows in a House
| Project Scope | Typical Total | Per Window |
|---|---|---|
| 10 windows, vinyl double-hung, insert | $4,000-$8,000 | $400-$800 |
| 15 windows, vinyl double-hung + low-e | $6,000-$12,000 | $400-$800 |
| 15 windows, fiberglass, low-e + triple-pane | $15,000-$30,000+ | $1,000-$2,000 |
| 15 windows, wood-clad, full-frame | $18,000-$35,000+ | $1,200-$2,300 |
| Bay or bow window (each) | $1,000-$3,000+ | Premium category |
Whole-house jobs (10+ windows) typically get a 5-10% volume discount from contractors - baked into the per-window range. Old-window disposal runs $50-$100 per window on top. Full-frame adds ~25% when frames are rotted or you're resizing.
What You're Paying For (on a $700 average window)
| Component | % of Total | What it covers |
|---|---|---|
| Window units (frame + glass) | 45-55% | The window itself - frame material (vinyl, wood, fiberglass, aluminum) and glass package (double, low-e, triple). The single biggest cost driver; premium materials and triple-pane push this toward 55%. |
| Labor (removal + install + trim) | 30-40% | Old window removal, new unit setting, leveling, insulating, interior and exterior trim, finish work. Full-frame installation adds 20-30% labor vs insert because the opening is exposed and re-trimmed. |
| Disposal (old windows + haul-away) | 5-8% | Old window haul-away and dump fees. Homes built before 1978 may need lead-safe removal (RRP rule), which adds labor and containment cost per window. |
| Permit + overhead + contractor profit | 8-12% | Building permit (where required), contractor insurance, equipment, scheduling, and profit margin. Many jurisdictions don't permit window swaps, but egress and full-frame changes often trigger one. |
Premium materials and triple-pane glass push the window-unit share toward 55%; full-frame installation and rot repair push the labor share toward 40%. Disposal can spike on pre-1978 homes requiring lead-safe removal.
Is the Energy-Efficient Glass Upgrade Worth It?
The glass package is the one upgrade with a measurable payback. Energy Star estimates that upgrading old single-pane windows to efficient double-pane with low-e coating saves $15-$30 per window per yearin heating and cooling, depending on climate. On a 10-window project, that's roughly $150-$300 per year, or $3,000-$6,000 over 20 years - often enough to offset the low-e premium several times over.
Low-e coating (+15%): almost always worth it
Low-e is a microscopic metallic layer that reflects heat back to its source. In winter it keeps heat in; in summer it keeps heat out. It adds about 15% to the window and typically pays back within a few years. In hot climates (South, Southwest) it cuts cooling load; in cold climates (Northeast, Mountain) it cuts heating load. Unless you're replacing a garage or outbuilding window, low-e is the right default.
Triple-pane (+40%): only in cold climates or noisy sites
Triple-pane adds a third glass layer and a second gas-filled gap. It's 30-50% more expensive than double-pane and insulates better, but the payback period is long. In extreme cold climates (Mountain states, Northern Midwest) or on noisy streets where the extra sound insulation matters, triple-pane earns its premium. In mild or moderate climates, the payback can exceed the window's 20-30 year lifespan - skip it and put the money into low-e on more windows instead.
How Location Affects Your Cost
| Region | Labor | Materials |
|---|---|---|
| National average | 1x | 1x |
| Northeast (cold climate, high labor) | 1.15x | 1x |
| West Coast (high labor, strict energy code) | 1.25x | 1x |
| Southeast (mild climate, lower labor) | 0.95x | 1x |
| Midwest & Mountain (cold, freeze-thaw) | 1.1x | 1x |

5 Factors That Change Your Window Replacement Cost
1. Window type (10x range)
A single-hung runs $200-$450 installed; a bay or bow window runs $1,000-$3,000+. The type is the single biggest cost driver after count. Bay and bow windows cost more because they project outside the wall - structural header work, a cap or roof, interior seat finishing, and multiple joined units.
2. Frame material (1.7x range)
Aluminum (0.85x) is cheapest but conducts heat. Vinyl (1.0x) is the right default. Fiberglass (1.4x) is strongest and longest-lasting. Wood (1.5x) is most expensive and needs repainting, but it's the only frame that adds resale value. For a forever home, fiberglass or wood-clad pays back; for a starter home, vinyl is the smart money.
3. Glass package (2x range)
Single-pane is largely obsolete for heated homes. Double-pane is the modern baseline and code-required in most climates. Low-e (+15%) pays back in a few years. Triple-pane (+40%) only earns its premium in extreme cold or noisy sites. The glass choice also drives your energy savings.
4. Installation method (insert vs full-frame)
Insert replacement reuses the existing frame and costs about 25% less. Full-frame tears the window out to the rough opening and costs 25% more - but it's required when the old frame is rotted, out of square, or you're resizing. Always require a frame inspection before agreeing to insert.
5. Region and labor (1.3x range)
The West Coast is the most expensive (25% over national) due to high labor rates and California Title 24 energy code. The Northeast runs 15% over for cold-climate glass demand. The Southeast runs 5% under. Local labor varies 30%+ between regions, and energy code (IECC climate zone) can rule out the cheapest glass. Hurricane zones may need impact-rated glass - a separate premium.
Red Flags When Calling Window Replacement Contractors
- Quoting insert replacement without inspecting the frame: Insert (pocket) replacement is only safe when the existing frame is square, plumb, and rot-free. A contractor who quotes insert over the phone or without probing the old frame is burying hidden rot - and you'll pay to fix it after the new window is in. Always require an in-person frame inspection before agreeing to insert.
- Pushing triple-pane in a mild climate: Triple-pane glass adds 30-50% to the window and only pays back in extreme cold. A contractor in the Southeast or mild West Coast pushing triple-pane on every opening is upselling, not engineering. In mild climates double-pane with low-e is the right call.
- No mention of Lead RRP for pre-1978 homes: If your home was built before 1978, federal law requires lead-safe work practices (RRP rule) on window replacement - the contractor must be RRP-certified. A contractor who doesn't ask the age of your home or mention lead containment is cutting a federal requirement.
- One quote, one brand: A contractor who only installs one brand will recommend that brand regardless of your budget or needs. Window brands (Andersen, Marvin, Pella) have different price points and strengths. Get quotes from at least two contractors carrying different brands, and compare the spec - not just the name.
- Skipping the egress check on bedrooms: Bedroom windows must meet egress (escape) size minimums - replacing a bedroom window with a smaller unit is a code violation and a fire-safety failure. Confirm the new unit meets local egress before it's ordered.
- Vague warranty or "lifetime" with no fine print: "Lifetime" window warranties are full of fine print - some cover the glass seal only, some prorate after 5 years, some don't cover labor to reinstall. Get the actual warranty document, and ask who honors it if the contractor goes out of business.

Frequently Asked Questions
How much does it cost to replace a window in 2026?
A replacement window costs $300 to $2,500 installed in 2026, with the national average around $600-$1,000 per window. A standard double-hung vinyl window - the most common replacement - runs $300-$700 installed. Upgrading to wood or fiberglass frames, triple-pane glass, or full-frame installation pushes the per-window cost to $1,000-$2,500. Bay and bow windows are the premium category at $1,000-$3,000+ each because they project outside the wall and need structural header work. Old-window disposal adds $50-$100 per window. For a full house (10-15 windows), expect $4,000-$12,000 for standard vinyl and $15,000-$30,000+ for premium wood or fiberglass with triple-pane.
What is the cheapest replacement window?
Single-hung windows are cheapest at $200-$450 installed - only the bottom sash opens, so they cost less to build than double-hung. Double-hung ($300-$700) is the most popular replacement because both sashes tilt in for cleaning. Aluminum frame windows are about 15% cheaper than vinyl, but metal conducts heat and costs you in energy bills, so aluminum only makes sense for garages or mild climates. The cheapest practical combo for a heated home is a vinyl single-hung with double-pane glass - but the better value is usually a vinyl double-hung at $300-$700, since it ventilates better and cleans easier. Window brands (Andersen, Marvin, Pella) sit at different price points, but the frame material and glass package move the price more than the brand name.
Vinyl vs wood vs fiberglass windows - which frame is best?
Vinyl ($300-$700 baseline) is the right default for most homeowners - cheapest, lowest maintenance, good insulation, 20-30 year lifespan. Aluminum (15% cheaper) conducts heat and is a poor choice for heated homes; reserve it for garages or mild climates. Fiberglass (40% more than vinyl) is the contractor-preferred premium - strongest frame, won't warp, 30-50 year lifespan, best efficiency after wood. Wood (50% more than vinyl) is the most expensive and needs repainting every 5-8 years, but it's the only frame that adds resale value and offers classic aesthetics. For a forever home, fiberglass or wood-clad pays back; for a starter home you'll sell in 10 years, mid-range vinyl is the smart money.
Is triple-pane or low-e glass worth the upgrade?
Low-e coating (about 15% more) is almost always worth it - it reflects heat back to its source, cutting both heating and cooling costs, and typically pays back within a few years. Energy Star estimates low-e or triple-pane saves $15-$30 per window per year versus single-pane. Triple-pane (40% more) is the harder call: it only pays back in extreme cold climates (Mountain, Northern Midwest) or on noisy streets where the extra sound insulation matters. In mild or moderate climates, the payback period can exceed the window's 20-30 year lifespan. The practical rule: low-e everywhere, triple-pane only in cold climates or noise-sensitive sites. For a 10-window project with low-e, that's roughly $150-$300 in annual savings - $3,000-$6,000 over 20 years.
How much does it cost to replace a basement or egress window?
Basement window replacement costs $300-$1,200 per window installed. A standard basement slider or awning runs $300-$700. Upgrading to an egress window (required for basement bedrooms) costs $2,500-$5,500+ because it involves cutting the foundation wall, installing a window well, and meeting the IRC escape minimum of 5.7 sq ft open area, 24-inch minimum height, and 20-inch minimum width. Egress window well installation adds $500-$1,500. If your home was built before 1978, federal law requires lead-safe work practices (RRP rule) on window replacement - the contractor must be RRP-certified, which adds about $40/window. Never replace a basement bedroom window with a smaller unit - it fails egress code and is a fire-safety hazard.
How much does it cost to replace all the windows in a house?
Replacing all windows in a house costs $4,000 to $12,000 for a typical 10-15 window home with standard vinyl double-hung windows and insert installation. The same house with wood or fiberglass frames and triple-pane glass runs $15,000 to $30,000+. Bay or bow windows add $1,000-$3,000 each. Full-frame installation (when frames are rotted or you're resizing) adds about 25% to the total. Old-window disposal runs $50-$100 per window. The per-window price drops slightly on whole-house jobs because contractors discount for volume - expect 5-10% off on 10+ window projects. Get at least three quotes; whole-house window pricing varies 30%+ between contractors carrying different brands.
Does homeowners insurance cover window replacement?
Only for sudden, accidental damage - not age or wear. A tree falling through a window, a break-in, or a hailstorm is typically covered (after your deductible). Rotting frames, failed seals between glass panes, fogged glass, and normal aging are all considered maintenance and are excluded. If your window was damaged by a covered peril, document it with photos before any repair and file the claim promptly. If the damage is from settling, poor installation, or just old age, insurance won't pay - and a previous owner's unpermitted window change can complicate a claim. The best insurance for windows is buying units with a strong glass-seal warranty and keeping the documentation.
How much does window hardware replacement cost (latch, lock, crank)?
Window hardware replacement - latches, locks, crank handles, balances - costs $50-$200 per window including parts and a service call. A broken sash lock runs $15-$40 in parts; a casement crank operator is $40-$90; a sash balance (the spring that holds a double-hung window up) is $25-$60 per side. Most companies charge a $75-$120 service-call minimum, so batch several windows into one visit. Hardware-only repairs don't require a full window replacement - if the glass and frame are sound, swapping the hardware extends the window's life by years. If two or more balances have failed on the same window, the sash is likely the problem and replacement may make more sense than another repair.
