Window replacement runs $300 to $1,300 per window installed in 2026. Most homeowners replacing standard double-hung or sliding windows in vinyl or fiberglass pay $450 to $900. For a whole-house project covering 10 to 15 openings, budget $5,000 to $15,000 with vinyl frames or $10,000 to $25,000 with wood or fiberglass. Those numbers include materials, labor, disposal, and basic finish work.
The spread is wide because the category spans everything from a $300 builder-grade vinyl insert to a $2,500 custom wood casement with full-frame installation. Your actual number depends on window type and frame material first, then installation method and access difficulty.

What Drives the Price: Window Type
Window style matters more than any other single variable. A standard rectangular window that drops into an existing opening costs a fraction of a specialty shape that requires structural work.
| Window Type | Installed Cost | Notes |
|---|---|---|
| Double-hung | $300–$700 | Two operable sashes, the most common residential replacement style |
| Single-hung | $250–$600 | Bottom sash only. Slightly cheaper than double-hung |
| Sliding | $300–$800 | Horizontal track. Good for wide openings where casements would swing into a walkway |
| Casement | $400–$1,000 | Crank-operated, hinged at side. Tightest air seal of any operable window type |
| Awning | $400–$900 | Hinged at top. Often paired above or below fixed glass |
| Picture (fixed) | $250–$800 | No moving parts — cheapest per square foot of glass. Price scales with size |
| Bay | $1,500–$5,000 | Three-panel projection. Structural support and interior/exterior build-out included |
| Bow | $2,500–$8,000 | Four to six panels in a gentle curve. More glass and specialized curved framing |
Double-hung and sliding windows dominate the replacement market because they fit standard openings with zero structural modification. Bay windows typically cost 4 to 7 times more than a standard double-hung, and bow windows 5 to 10 times more, because the job includes header reinforcement plus exterior and interior build-out (seat, shelf, drywall returns).
Basement egress windows are a different animal entirely — $2,500 to $5,500 per opening because you’re cutting through a concrete foundation, not just swapping glass.
Frame Material: Where Budget Meets Longevity
Frame material controls how much you pay upfront and how many decades the window lasts before you’re back at square one. Prices below are for a standard double-hung:
| Frame Material | Installed Cost | Lifespan | Maintenance | R-Value (Frame) | Best For |
|---|---|---|---|---|---|
| Vinyl | $300–$700 | 20–30 years | None | R-0.4–R-0.5 | Budget-friendly whole-house projects |
| Aluminum | $350–$850 | 25–35 years | Minimal — may oxidize | R-0.3 (with thermal break) | Modern aesthetics, warm climates |
| Fiberglass | $500–$1,200 | 30–50 years | Minimal — paintable | R-0.5–R-0.7 | Long-term homeowners, extreme climates |
| Wood | $700–$1,500+ | 30–50+ years | Paint/stain every 3–5 years | R-0.7–R-1.0 | Historic homes, high-end renovations |
Vinyl handles over 70% of residential replacement jobs nationally, and there’s a reason for that. It costs 40 to 60% less than wood installed, requires zero exterior maintenance, and meets current energy codes in every US climate zone. The downsides are cosmetic: limited color options, visible welded corners, no stain-grade profiles. On south-facing walls in desert climates, vinyl can warp when surface temperatures stay above 160 degrees for extended periods. That’s a real concern in Phoenix, not in Philadelphia.
Fiberglass occupies the middle ground and deserves more attention than it gets. It costs 30 to 50% more than vinyl but expands and contracts at nearly the same rate as the glass itself. That means tighter seals over decades. For anyone planning to stay 15 or more years, fiberglass often delivers the lowest cost per year of service. Pella’s material comparison breaks down how vinyl compares to fiberglass and wood on price. Expect 4 to 8 week lead times on custom fiberglass sizes.
To put this in concrete terms: a 10-window vinyl project runs about $6,000 installed with zero maintenance and roughly $200 per year in energy costs (U-factor around 0.30). The same project in fiberglass runs $9,500 installed with roughly $180 per year in energy costs (U-factor around 0.25, based on typical NFRC-rated units). After 10 years, total outlay is $8,000 for vinyl versus $11,300 for fiberglass. Vinyl wins on total 10-year outlay by $3,300. Fiberglass closes that gap over the next 10 to 20 years through longer lifespan and fewer seal failures. Selling within a decade? Vinyl is the rational pick. Staying long-term? Run the numbers on fiberglass.
Wood remains the right choice for historic districts and high-end builds where local codes or HOA covenants require specific profiles. The maintenance commitment is real: $50 to $100 per window every 3 to 5 years for full exterior prep and recoating. Skip a cycle and rot starts at the sill corners where water pools. At that point you’re paying for full-frame replacement instead of a simple insert swap.
One mistake that costs people money: choosing frame material before measuring openings. If your home has non-standard sizes (common in pre-1960 construction), vinyl stock options shrink dramatically and custom-order prices close the gap with fiberglass. Measure first, then decide on material.
Insert vs Full-Frame: A 50% Price Swing
This single decision can double your project cost per opening.
With an insert (pocket) replacement, a new window unit slides into the existing frame. Old trim stays in place. Cost: $300 to $1,000 per window. A good crew handles one opening in 30 to 60 minutes. Choose this when frames are square and solid with no rot.
Full-frame replacement tears everything down to the rough opening: sashes, frame, trim, sometimes exterior cladding. Cost: $600 to $2,500 per window, roughly double the insert price. Each opening takes 2 to 4 hours. If frames are rotted, out of square by more than a quarter inch, or you’re switching to a different window size, full-frame is the only option — insert won’t hold and the warranty won’t cover it.
There’s a trade-off most guides skip: insert replacement shrinks your glass area by 1 to 2 inches on each side because the new frame nests inside the old one. On a standard 36-inch double-hung, that’s about 6% less glass. Barely noticeable. On a small 24-inch bathroom window, the difference is visible.
Before you commit to insert, check for rot. Press your thumb firmly into the wood sill and frame at each corner. If the wood compresses at all, you’re in full-frame territory. Rot has already compromised the substrate that an insert depends on, and no amount of caulk will fix that.
Things That Push Costs Higher
The lower end of published ranges assumes a clean swap on a ground-floor window. Real projects rarely stay that simple.
Upper-floor access is the most predictable upcharge. Second-floor windows add $50 to $150 each for ladder time. Third-floor windows or openings above a porch roof may need a boom lift at $300 to $600 per day rental. A two-story colonial with 8 to 10 upstairs windows carries an access premium of $400 to $1,500 on top of the base quote.
Custom and non-standard sizes hit harder than people expect. Factory-ordered units carry a 30 to 60% premium over stock, plus 4 to 8 week lead times. Homes built before 1950 are almost guaranteed to have non-standard openings. Measure every window. Pre-war dimensions rarely match modern stock sizes, and specialty shapes like round-tops or arched transoms push costs further still.
Lead paint is the surprise that derails budgets on older homes. If the house was built before 1978, EPA RRP Rule compliance adds $100 to $300 per window for containment and disposal. The contractor must be EPA-certified. A common scenario on pre-1978 jobs: the homeowner tests interior trim, gets a clean result, and assumes the opening is clear. Then the crew pulls the exterior casing and finds three layers of lead paint underneath. Full RRP protocol kicks in mid-job (containment, HEPA vacuuming, clearance testing), and the change order adds $2,000 to $4,000 across a 10-window project.
Rot discovered during removal adds $200 to $500 per opening for sill or header repair. On homes older than 40 years, expect at least 2 to 3 openings needing some structural work. Historic preservation requirements can double or triple per-window cost on top of that. Designated historic districts mandate true-divided lites and wood-only frames, which eliminates vinyl entirely.
Regional Pricing
Window replacement cost varies 20 to 30% across the country, driven by labor rates and climate-specific product requirements:
| Region | Per Window (Standard DH, Vinyl) | 10-Window Project | vs National Avg |
|---|---|---|---|
| Northeast (NY, NJ, CT, MA) | $550–$1,100 | $7,000–$14,000 | +15–25% |
| Midwest (OH, IL, MI, MN) | $400–$800 | $5,000–$10,500 | −5% to +5% |
| Southeast (GA, FL, NC, TX) | $350–$750 | $4,500–$9,500 | −10% to 0% |
| West Coast (CA, WA, OR) | $550–$1,000 | $6,500–$13,000 | +10–20% |
| Mountain West (CO, UT, AZ) | $400–$850 | $5,000–$11,000 | −5% to +5% |
The 10-window column runs higher than a simple 10x because whole-house projects typically include a mix of window types, some upper-floor surcharges, and mobilization costs that per-unit pricing does not capture.
The Northeast premium reflects partly union labor, partly compressed installation seasons. Contractors there are booked 4 to 6 weeks out from April through October, and that backlog pushes prices up. In hurricane zones along coastal Florida and the Gulf, code-required impact glazing adds $100 to $300 per window on top of the regional baseline. Mountain West and Southeast installers work year-round and don’t carry union overhead — both translate directly into lower bids.
Repair or Replace?
Window repair (reglazing, weatherstripping, hardware) costs $75 to $350 per window and makes sense for isolated problems on otherwise sound frames. The signs you need new windows page covers the full checklist. Replacement becomes the better move when problems start stacking up:
Foggy glass between panes means the insulated glass unit (IGU) seal has failed. Replacing just the IGU costs $150 to $400 — worth doing if it’s one window in otherwise good shape. But if several seals have blown, the frames are aging out too, and chasing them one by one over the next few years costs more than replacing the batch now.
Soft spots in wood frames or visible gaps between frame and wall mean water has reached the rough opening. Surface patches ($100 to $200) rarely stop the underlying moisture path. You’ll be back within two years, and the contractor’s structural repair will cost $200 to $500 per opening on top of whatever replacement window you were going to buy anyway.
Drafts that persist after new weatherstripping tell you the sash-to-frame fit has degraded past fixable. Common in windows older than 25 years. Try this: hold a lit candle near the closed window on a windy day. If the flame flickers, the seal is gone. No weatherstripping fixes a warped frame.
Millions of US homes still have at least some single-pane windows. Replacing them delivers the biggest energy impact of any window upgrade. ENERGY STAR estimates up to 13% reduction in heating and cooling costs when swapping single-pane for certified double-pane units.
If you’re already planning siding replacement or exterior painting, do the windows at the same time. Contractors discount combined projects by 5 to 10%, and you avoid paying for scaffolding twice.
The Energy Savings Reality
The payback math on window energy savings is almost always worse than the sales pitch. Replacing single-pane windows with ENERGY STAR certified double-pane saves up to 13% on heating and cooling, but that ceiling applies only to the worst-performing homes in cold climates. For a household spending $2,400 per year on energy, the realistic range is $170 to $310 in annual savings. Replacing existing double-pane with newer double-pane saves 3 to 7%, or $70 to $170 per year. On most utility bills that’s rounding error.
At those rates, a $10,000 whole-house project pays for itself in energy alone over 30 to 60 years. Longer than most windows last. That’s why energy savings alone never justify the investment.
The stronger financial case combines comfort (no more drafts, no more cold spots by the windows in January), noise reduction, and the 67 to 69% cost recoup at resale for vinyl that the JLC Cost vs. Value report consistently shows. Wood window replacements recoup slightly less, around 61 to 63%.
One note on tax credits: the federal Section 25C Energy Efficient Home Improvement Credit expired December 31, 2025 . Windows installed in 2026 do not qualify. Some state-level rebates and utility programs still exist, so check the DSIRE database for your area.
Getting Quotes That You Can Actually Compare
Bids for the same 10-window project routinely range from $6,000 to $12,000. The gap comes from window brand and installation method on one side, warranty scope and structural contingencies on the other.
Three in-home estimates is the minimum — phone quotes and online calculators cannot assess opening condition or access difficulty. Accurate numbers only emerge after a contractor has measured every opening, checked frame condition, and confirmed access to upper floors. The window contractor hiring guide covers what to ask during bids and which red flags to watch for.
Lock in a specific window line before collecting bids. An Andersen 100 Series or Pella 250 Series (whatever fits your budget) quoted across three contractors isolates the labor variable. Without that discipline, you’re comparing a $300 builder-grade vinyl against a $900 fiberglass and learning nothing useful.
Before you sign, confirm two things in writing. First, whether the bid covers insert or full-frame replacement — a low insert bid and a higher full-frame bid describe completely different scopes of work. Second, a per-opening price for sill or header repair if rot is discovered during removal. Any contractor unwilling to put that unit price in writing is planning to negotiate it on demo day when you have no leverage.
Manufacturer-certified contractors (Andersen Certified, Pella Platinum, Marvin Authorized) complete product-specific installation training and can offer extended warranties that generic installers cannot. That means 20 years on glass seal instead of 10 in some cases.
January through early March is the slowest season for window contractors in most of the country. Quotes come back faster and pricing has more flexibility because crews aren’t booked out six weeks.
Any bid more than 40% below the others warrants a hard look at what’s being left out — low outliers almost always reflect a thinner warranty, an insert bid where others quoted full-frame, or a contractor skipping the structural repair allowance entirely. Use the window type and material tables above to sanity-check the line items, and the window types comparison guide if you’re still undecided on style.
