Window Replacement Cost in 2026 (Per Window + Whole House)

Window replacement runs roughly $553 to $1,063 per window installed for common 2026 choices — about $650 for a standard vinyl double-hung and around $850 for a like-for-like fiberglass one — and a whole house of about 10 windows lands roughly $5,525 to $10,625. The math is simple: per window = material + labor, and the whole-house total = per-window price × your window count. Frame material, window type, glass package, and whether the installer keeps or removes the old frame are what move you inside that band. You can price your exact project with our Window Replacement Cost Calculator, then use the ranges below to sanity-check the bids you get. Every figure here is a planning estimate that shifts with your market and condition, not a quote.

The two numbers: per window vs. whole house

People mix up two different prices. The per-window installed price is what one finished opening costs — the window unit (material) plus the labor to fit and seal it. The whole-house total is just that per-window price multiplied by how many windows you're doing. Get the per-window number right and the total falls out of it: per window = material + labor, and total = per-window × window count.

For common choices, the per-window installed price runs about $650 for a standard vinyl double-hung and about $850 for the same window in fiberglass, with the realistic spread across typical homes landing roughly $553 to $1,063 each. On an average home of about 10 windows, that's a whole-house range of roughly $5,525 to $10,625. The figures below are 2026 US estimates; your actual cost depends on the choices in the next few sections plus local labor rates.

• Material = the window unit itself (base ~$400, scaled by type, frame, glass, and size)
• Labor = the install (base ~$250, scaled by install method, window type, and region)
• Per-window installed = material + labor
• Whole-house total = per-window installed × number of windows
• Always confirm whether a quote is per-window or whole-house before comparing two bids

2026 cost per window by frame material

Frame material is the first big lever, and it moves the material side only — labor is identical across frames because the install effort is the same. The table below is a like-for-like double-hung, double-pane low-E window installed as an insert in a standard opening, at a neutral labor region. Vinyl is the value baseline; aluminum sits just above it; fiberglass and wood are the premium tiers.

The gap between vinyl and fiberglass — about $200 per window, or roughly $2,000 on a 10-window house — is entirely material; the labor is the same $250 either way. That trade-off (lower price vs. better durability and dimensional stability) is the whole decision for a lot of homeowners, and we break it down in detail in our vinyl vs. fiberglass window cost comparison. Wood lands just above fiberglass and brings a classic look at the highest material cost.

• Vinyl: about $650 installed per window (material $400 + labor $250)
• Aluminum: about $690 installed per window (material $440 + labor $250)
• Fiberglass: about $850 installed per window (material $600 + labor $250)
• Wood: about $890 installed per window (material $640 + labor $250)
• Realistic band on a vinyl window: roughly $553 low to $813 high

How window type moves the price

Window style changes both the unit and, for a few types, the labor. Holding everything else fixed (vinyl, double-pane, standard size, insert install), most operable styles cluster close together — double-hung and sliding are the baseline, picture and awning are a touch more, and casement carries a small labor bump because it's a crank-operated sash. Bay and bow windows are the outlier: they're a single large multi-panel assembly that costs far more in both material and labor, so they're priced as one big unit rather than a standard opening.

If you're mixing styles across the house, price each opening to its type and add them up rather than applying one average. A single bay window can cost as much as four or five standard openings on its own.

• Double-hung: about $650 per window (baseline)
• Sliding: about $650 per window
• Picture / fixed: about $690 per window
• Awning: about $703 per window
• Casement: about $735 per window (carries a small labor bump for the crank mechanism)
• Bay / bow: about $2,660 as one large unit (material ~$1,760 + labor ~$900)

Glass and size upgrades

Two common upgrades push the material cost up without touching labor. Moving from a standard double-pane low-E to a triple-pane glass package adds roughly $120 on a vinyl window — about $650 goes to $770 — and the upcharge is larger on pricier frames because it scales the material: a fiberglass window goes from about $850 to about $1,030, roughly a $180 step. Triple-pane is generally quieter and more insulating than double-pane, but treat that as a trade norm, not a guaranteed dollar saving — the calculator doesn't model energy bills.

Size works the same way. A large or custom-sized opening scales the material cost up while labor stays put: a standard vinyl double-hung at about $650 becomes about $830 in a large size, roughly a $180 material step. Oversized and architecturally shaped openings are where custom pricing climbs fastest, so measure before you assume a standard rate applies.

• Vinyl double-pane → triple-pane: about $650 → $770 per window (~$120 material)
• Fiberglass double-pane → triple-pane: about $850 → $1,030 per window (~$180 material)
• Vinyl standard → large/custom size: about $650 → $830 per window (~$180 material)
• Both upgrades hit material only — labor is unchanged

Insert vs. full-frame install

How the installer puts the window in is a labor decision, and it's the one most people underestimate. An insert (or retrofit) drops the new window into the existing frame — fast, less invasive, lower labor. A full-frame replacement tears out the old frame down to the rough opening, which is more work, so the labor is scaled up by about 1.7×. On a vinyl double-hung that takes labor from $250 to about $425, moving the installed price from about $650 to about $825 — and importantly, the material cost doesn't change, because it's the same window either way.

Full-frame isn't an upsell for its own sake; it's what you do when the old frame is rotted, out of square, or you're changing the window size. Across a 10-window house, choosing full-frame over inserts is roughly a $1,750 difference (about $8,250 vs. $6,500). Whether that extra invasiveness is justified is its own question — our guide on when window replacement is worth it walks through the signals that point to a full tear-out versus living with what you have.

• Insert / retrofit: about $650 per vinyl double-hung (labor $250)
• Full-frame replacement: about $825 per vinyl double-hung (labor ×1.7 = $425)
• The difference is entirely labor — full-frame is more invasive, not a more expensive window
• 10-window house: roughly $6,500 (insert) vs. $8,250 (full-frame)

Whole-house total by window count

To get a whole-house number, multiply your per-window price by your window count. The table below uses the two most common choices — vinyl at about $650 and fiberglass at about $850 per window — across 8, 10, 15, and 20 windows. These assume a like-for-like insert install at a neutral region; mix in full-frame openings, triple glass, large sizes, or bay windows and your real total climbs above the vinyl column.

Every per-window estimate carries a band: the calculator's realistic figure sits in the middle, with a low of about 0.85× and a high of about 1.25× to cover the spread between a clean, easy job and a difficult one. So a 10-window vinyl project shown at about $6,500 realistically ranges roughly $5,525 to $8,125 once you account for access, condition, regional labor, and the exact unit tier. Use the midpoint to plan and the high end to avoid surprises.

• 8 windows: about $5,200 vinyl / about $6,800 fiberglass
• 10 windows: about $6,500 vinyl / about $8,500 fiberglass
• 15 windows: about $9,750 vinyl / about $12,750 fiberglass
• 20 windows: about $13,000 vinyl / about $17,000 fiberglass
• Range band: realistic × 0.85 (low) to realistic × 1.25 (high) — e.g. 10 vinyl windows run roughly $5,525–$8,125

The bottom line

In 2026, plan on roughly $553 to $1,063 per window installed for common choices — about $650 for vinyl, about $850 for fiberglass — with a whole house of about 10 windows landing roughly $5,525 to $10,625. Keep the formula in mind: per window = material + labor, and total = per-window × count. Frame material and glass move the material side, install method (insert vs. full-frame) and region move the labor side, and bay/bow windows are priced as their own large unit. Plug your exact frame, type, glass, size, install method, and window count into our Window Replacement Cost Calculator to turn these ranges into a project number — then treat every figure as a planning estimate that varies by market and condition, not a quote.
