Window replacement is one of those projects where the range of prices you’ll find online is almost useless on its own, because window replacement cost depends heavily on window type, material, size, installation method, and how many windows you’re replacing at once. This guide breaks down real numbers for Madison-area homes, from the price of a single window to the full house windows cost for a whole-home project, so you can budget with confidence before you ever request a window replacement quote.
The Short Answer
For a standard vinyl double-hung window installed, most Madison homeowners can expect to pay between $1,500 and $2,500 per window, depending on size and features. Double hung window replacement cost tends to sit in the middle of that range for most homes, which makes it a good benchmark for the average replacement window cost and the average cost to replace a window on a typical project.
The average cost for replacement windows installed across a whole house depends mostly on how many windows you’re replacing. Most Madison homes with 10 to 20 windows land between $20,000 and $40,000, and specialty windows such as bay, picture, egress, or custom shapes run higher. Here’s how the numbers break down.
Window Replacement Prices by Window Type
Window replacement prices vary more by window style than by almost anything else. Here’s how replacement windows pricing typically compares by style, per window, installed:
| Window type | Typical installed cost per window | Notes |
|---|---|---|
| Double-hung (vinyl) | $1,500 – $2,500 | The most common style in Madison homes |
| Sliding / casement | $1,500 – $3,000 | Casements cost more for their crank hardware |
| Picture window | $1,500 – $3,500 | Priced mainly by glass size |
| Bay or bow window | $4,000 – $10,000+ | Multiple units plus structural support |
| Egress window (basement) | $3,500 – $7,000+ | Includes excavation, window well, and cutting the opening |
| Skylight | $2,000 – $5,000+ | Includes roof flashing and interior finish work |
| Specialty shapes (arched, palladian) | $1,500 – $4,000+ | Custom manufacturing adds cost |
Double-Hung Windows
Double-hung windows are the style most Madison homeowners are replacing. Double hung window prices start at the low end of the range for standard sizes, and double hung window installation cost rises with size, glass package, and any repair needed around the opening. When you compare double hung window cost between quotes, check that both include the same glass package, trim work, and installation method, because double hung windows prices can look very different for reasons that have nothing to do with the window itself.
Picture Windows
Picture windows don’t open, so there’s no hardware to pay for, but their large glass area drives the price. Picture window replacements are priced mainly by size and glass package. Many homeowners choose replacement picture windows with a slightly higher-performance glass to cut heat loss through such a large surface. Picture windows replacement is also a good time to consider flanking the picture window with operable windows for ventilation.
Egress Windows
Egress windows are required for basement bedrooms and involve more structural work than any other window type: excavating outside, installing a window well, and cutting or enlarging the foundation opening. Because of that, it’s important to hire experienced egress window installation contractors. Look for basement egress window installers who handle the excavation, well, drainage, and window as one project, so nothing falls through the cracks.
Skylights
Skylights replacement is priced separately from standard windows because it involves roof work: removing the old unit, installing new flashing, and tying it into your roofing. If your roof is nearing replacement, combine skylight window replacement with your roof project to save on labor and get a watertight seal from day one.
Specialty Shapes
Arched windows, half-rounds, and palladian windows (an arched center window flanked by two smaller ones) are custom manufactured for each opening. Custom windows cost more because of that custom fabrication, but they’re often what gives an older Madison home its character.
Whole-House Window Costs: How Much Are New Windows for a House?
How much are new windows for a house? Multiply your per-window cost by the number of windows, then expect some savings on larger projects. Here’s what typical projects look like with standard vinyl double-hung windows:
- How much does it cost to replace 10 windows? Typically $20,000 to $25,000.
- What’s the average cost to replace windows in a 3 bed house? Most three-bedroom homes have 10 to 15 windows, so $20,000 to $30,000 is typical.
- 20 windows: $32,000 to $40,000.
- How much does it cost to replace 25 windows? $38,000 to $50,000, often with a lower price per window than smaller projects.
Full-house projects usually bring a better cost for window replacement per unit, lowering the replacement windows cost per window, since setup and labor scale more efficiently. That’s why the cost of replacing windows in a house all at once is often lower per window than replacing them a few at a time over several years. When you’re estimating how much to replace windows in a house, or the cost to replace windows in house projects with unusual openings, remember that specialty windows, unusual sizes, and repairs around the openings will push the total higher.
What Actually Drives Window Replacement Cost
Several factors determine your window replacement costs, and understanding them makes it much easier to compare quotes.
1. Frame Material
Vinyl is the most common and most budget-friendly option for Wisconsin homes, offering strong energy efficiency without the maintenance of wood. The cost of vinyl replacement windows is usually the lowest of any frame material. Composite windows and fiberglass frames cost more but offer extra durability, better resistance to temperature swings, and narrower frames with more glass. Wood window replacement is the premium option, often chosen for historic homes, and it requires more upkeep over time.
2. Glass and Energy Performance
Double-pane glass with a low-E coating is now the standard for Wisconsin’s climate. Upgrading to triple- pane adds cost but can meaningfully cut heating bills and drafts through a Madison winter. For homes near busy roads, laminated or specialty glass can also turn standard units into nearly sound proof windows.
3. Number of Windows and Installation Complexity
Homes with unusual window sizes, historic trim, or structural issues around the openings will see higher installation costs. That’s exactly why a typical window replacement cost you see quoted online rarely matches what you’ll actually pay.
Double-Pane vs. Triple-Pane Window Cost
The double pane window cost is the baseline for most replacement projects in Madison, and it’s what most of the prices above assume. Double pane windows installation cost is the same as any other standard window installation; the glass upgrade is in the unit itself. Triple-pane glass typically adds 10% to 20% to the double pane windows cost per window, and it pays off most on north-facing walls and in rooms that never seem to stay warm.
Insert vs. Full-Frame Installation: How It Affects Cost
There are two ways to install replacement windows, and the method you choose is one of the biggest factors in your windows cost of replacement.
Insert (retrofit) windows fit inside your existing frame. Retrofit windows cost less to install and the job is less disruptive, but you lose some glass area, and a new window can’t fix a frame that’s already leaking or rotting.
Full-frame replacement removes the entire window down to the rough opening. It costs more in labor and materials, typically 15% to 30% more per window, but it maximizes glass area, exposes and fixes hidden rot, and delivers the best long-term energy efficiency and weather sealing. For a deeper comparison, see our guide to full-frame vs. insert replacement windows. Before you compare replacement windows cost estimates from different contractors, ask each one which installation method they’re quoting.
Vinyl Window Replacement Cost, Specifically
Since vinyl is the material homeowners ask about most, it’s worth breaking out on its own. Vinyl window replacement cost typically includes the window unit, removal of the old window, installation, and basic trim work. The cost to install vinyl windows varies most with energy package (double vs. triple pane), hardware quality, and whether any structural repair is needed around the opening, which is common in older Madison homes with settling or moisture damage around window frames.
If you’re comparing the cost to install vinyl replacement windows between contractors, make sure each quote uses the same installation method. Replacement vinyl windows cost less as inserts than as full-frame installations, so two quotes can look very different for that reason alone.
Why Window Costs Have Risen
Like most exterior materials, window manufacturing costs have climbed due to tariffs on aluminum components, vinyl resin pricing, and glass production costs. The cost of replacement windows has risen across nearly every brand and material. If you’ve been waiting for replacement window prices to come back down, that’s unfortunately not the direction the market has moved. That makes now a reasonable time to get a real window replacement estimate rather than keep waiting.
Don’t Overlook the Energy Savings
New windows aren’t just a cosmetic upgrade. Drafty, single-pane, or failed-seal windows are a real source of heat loss through a Wisconsin winter. If you’ve noticed condensation between panes, or drafts that no amount of caulking fixes, the window itself has usually failed, not just the seal around it. Our guide on how to seal windows for winter explains when sealing helps and when replacement is the better fix.
One note on tax credits: the federal energy-efficient home improvement credit for windows expired at the end of 2025, so windows installed in 2026 don’t qualify. The energy savings, comfort, and fewer drafts still make energy-efficient windows worth the investment.
Financing Your Window Project
A whole-house window replacement is a meaningful investment, and more homeowners are choosing to finance window replacement rather than pay the full amount upfront. Window financing can turn a five-figure project into a predictable monthly payment, so if the cost for new windows has kept you living with old, drafty windows, it’s worth a conversation.

Getting an Accurate Quote for Madison Window Replacement
The ranges above are a starting point, not a quote. A replacement windows cost calculator or house window replacement cost estimator online can give you a ballpark, but it can’t see your window sizes, frame condition, or what’s hiding behind the trim. A real window estimate requires someone to actually look at your windows. Window installation prices also vary between contractors based on crews, warranties, and installation method, so compare quotes line by line.
Window Replacement Cost FAQs
How much does a new window cost depends on style and size, but a standard vinyl double-hung window typically runs $1,500 to $2,500 installed in the Madison area.

How much does it cost to change windows on a smaller project? Expect the higher end of the per- window range, since setup and labor are spread across fewer windows. If you’re wondering how much to change windows in a single room, a free inspection will give you an exact number.
Usually, yes. The cost for replacing windows all at once is typically lower per window than spreading the work over several years, and you get the comfort and energy benefits everywhere at the same time.
How much do windows cost to replace in an older home often depends on what’s found around the openings. Rot, settling, and outdated framing may call for full-frame installation, which adds cost but fixes problems an insert would cover up.
