Window Replacement Cost Estimator

How much does window replacement cost?

Most homeowners pay $550 to $960 per window for standard vinyl replacement windows, installed, with $715 as a typical price. Replacing all the windows in a home with 10 windows usually costs $5,550 to $9,650. Wood or fiberglass frames, bigger sizes and full-frame installs push the price up from there.

Where your money goes

On a typical vinyl double-hung window, the window itself is about 59% of the bill and installation labor is about 31%. The rest covers materials such as sealant, insulation and shims, plus hauling the old window away.

Six things move the price the most: the window type, its size, the frame material, the glass package, how it's installed and where you live. Each one is covered below with real numbers, and the calculator above handles all six at once.

Window replacement cost by type

The style of window sets the starting price. Single-hung and sliding windows are the least expensive, casement and awning windows cost more because of their crank hardware, and bay and bow windows are small construction projects of their own.

Bay and bow windows

A bay window usually costs $3,200 to $5,500 installed, and a bow window $4,100 to $7,050. A bay has three panels, a large center window flanked by two angled ones. A bow has four to six panels set in a gentle curve. Both stick out from the wall, so the price covers structural support, a seat board, insulation underneath and a small roof or cable support above.

If you're replacing an existing bay, check the seat and the roof above it. Soft wood in either spot means carpentry on top of the window price, and it's far cheaper to fix while the window is out.

Window cost by frame material

Frame material is the biggest price lever you control. Vinyl is the value pick for most homes. Fiberglass and composite cost more but stay stable in heat and cold, and wood gives you the classic look with the most upkeep.

Climate should steer the choice as much as price. In hot, humid places like the Gulf Coast, vinyl and fiberglass shrug off moisture that slowly rots unprotected wood. In very cold regions, fiberglass and composite frames expand and contract less than vinyl, which keeps the seals tight for decades. Aluminum frames are inexpensive and strong, but they conduct heat, so they make the most sense in mild climates.

Glass options and energy ratings

The glass package changes both the price and how comfortable the room feels. Double-pane glass with a low-E coating and argon gas between the panes is the standard today, and it's what every price on this page assumes unless noted.

How to read the energy label

Rated windows carry a label from the National Fenestration Rating Council (NFRC). Four numbers on it tell you most of what you need to know:

• U-factor shows how well the window keeps heat in. Lower is better, and good replacement windows usually land between about 0.20 and 0.30.
• Solar heat gain coefficient (SHGC) shows how much of the sun's heat gets through. In hot climates, look for about 0.25 or lower. In cold climates, a higher number lets free winter sun warm the room.
• Visible transmittance shows how much daylight passes through. Higher means brighter rooms.
• Air leakage shows how much air slips through the window. Lower means fewer drafts, and 0.30 or less is the usual target.

ENERGY STAR sets different targets for different climate zones, so a window certified for Minnesota isn't the same as one certified for Louisiana. Check that your quote lists windows certified for your zone on the ENERGY STAR windows page.

Cost to replace all the windows in a house

Whole-house projects cost less per window than one-off replacements because the crew, the delivery and the setup get spread across more windows. These totals use standard vinyl double-hung windows.

Average cost to replace windows in a 3-bedroom house

A 3-bedroom house usually has 10 to 14 windows. With standard vinyl windows, most owners spend $6,650 to $11,600, about $8,580 for 12 windows. Larger windows, wood or fiberglass frames and full-frame installs can push that total much higher, so run your own numbers in the calculator.

Is it cheaper to replace all your windows at once?

Usually, yes. You pay for one trip, one setup and often one permit, and many companies discount larger orders. If the budget won't stretch that far, start with the windows in the worst shape, such as single-pane, rotted or fogged windows, and do the rest within a year or two so the styles and colors still match.

Window prices by size

Bigger windows cost more, but not in a straight line. A window with twice the glass area costs roughly 40 to 50 percent more, because labor, hardware and trim don't double with it.

How to measure your windows

1. Measure the width inside the frame at the top, middle and bottom. Write down the smallest number.
2. Measure the height from the top of the frame to the sill at the left, center and right. Again, keep the smallest number.
3. Measure both diagonals. If they differ by more than about a quarter inch, the opening is out of square, and you should mention it to your installer.
4. Round down to the nearest eighth of an inch. Your installer will re-measure before ordering, but these numbers make your estimate and quotes far more accurate.

Most replacement windows are made to order, so an unusual size isn't a problem. It may just add a week or two to the wait.

Window installation and labor costs

The window installation cost for a standard insert replacement runs $170 to $310 per window in labor, about $220 on average. A full-frame replacement takes longer, and its labor costs $320 to $590 per window.

Insert or full-frame?

An insert, also called a pocket replacement, slides a new window into your existing frame. It's faster, cheaper and leaves your interior trim alone. A full-frame replacement removes everything down to the studs, so the installer can check for hidden rot, add new flashing and insulation, and fit new trim inside and out.

Choose full-frame when the frame is rotted, water has gotten into the wall, you want to change the window size, or the old frame is badly out of square. On a typical vinyl window, going full-frame adds about $330 per window. If the frame is solid and dry, an insert does the job just as well.

Labor goes up on second and third floors because the crew needs taller ladders, staging or a lift, and every window takes longer to get in and out safely.

Extra costs to plan for

These are the line items that turn a good price into a surprise. Ask whether each one is included before you sign.

If your home was built before 1978, federal rules require contractors to use lead-safe work practices whenever they disturb painted surfaces, and removing old windows almost always does. That means plastic containment, special cleanup and a certified firm. Ask to see the company's certification, and read more on the EPA lead-safe renovation page.

Window replacement cost by state

Where you live changes the price mostly through labor. Installers in high-cost states charge noticeably more, while the window itself costs about the same everywhere. A standard vinyl window runs about $625 installed in Mississippi and about $875 in Hawaii.

What changes the price in your state

• Hurricane zones. Many coastal areas in Florida and along the Gulf and Atlantic coasts require impact-rated windows or approved shutters, which adds $240 to $400 per window.
• Heat and sun. In Louisiana, Texas and the rest of the South, low solar heat gain glass does more for comfort than an extra pane.
• Cold winters. Northern states see more triple-pane glass, which adds $80 to $120 per window.
• Big cities. Labor in metro areas like New York City, Boston and San Francisco often runs well above the state average.

Window prices by brand

The brand matters less than the series you pick and who installs it. Every major brand sells a value line and a premium line, and the same window can cost far more from one dealer than another. These are typical installed prices per window for standard sizes.

Pella window prices

Pella sells through its own showrooms and through retailers, and the series you choose drives the price more than anything else. The 250 Series is its value vinyl line, Impervia is fiberglass, and Lifestyle and Reserve are wood windows with aluminum cladding outside.

Andersen and Renewal by Andersen

Andersen windows are sold through dealers and home centers, from the 100 Series in Fibrex composite up to the A-Series. Renewal by Andersen is the company's full-service replacement business. It sells its own composite windows through in-home appointments and installs them with its own crews, which is why its prices land well above Andersen windows bought through a dealer, often $15,000 to $45,000 for 10 to 15 windows.

Home Depot and Lowe's window installation

Both stores sell windows from several brands and arrange installation through local contractors. Installed prices typically run $450 to $1,300 per window, depending on the brand and series you choose. The convenience is real, but the crew is whoever the store sends, so ask who will do the work, what the labor warranty covers, and whether permits and disposal are included in the price.

$199 windows: what's really included

Ads for windows "from $199 installed" are real offers, but that price usually covers a basic vinyl window in a limited size range. Once you add the glass, trim and fees most homes need, the real cost usually lands between $350 and $600 per window.

If an offer catches your eye, ask for a written, itemized quote that names the exact glass package and lists every fee. Then compare it with your estimate in the calculator above.

Window repair costs, and when to replace instead

Not every problem needs a new window. If the frame is solid and only one part has failed, a repair is often a fraction of the cost of replacement.

How long does window replacement take?

The installation itself is quick. Most of the wait is for the windows to be built, since replacement windows are made to your exact sizes.

1. Measure and compare quotes

   1 to 2 weeks

   Get two or three companies out to measure, then compare itemized quotes side by side.

2. Order and manufacturing

   4 to 12 weeks

   Custom windows are built to order. Stock sizes from a home center can arrive sooner.

3. Installation day

   1 to 2 days for most homes

   An insert window takes 30 to 60 minutes, a full-frame window 2 to 4 hours. A crew usually handles 8 to 12 insert windows a day.

4. Finishing and inspection

   Same day to 1 week

   Trim, caulk and cleanup wrap up the job, plus a final inspection if your city required a permit.

Why are windows so expensive?

A replacement window is a custom product fitted into a hole in your house, and much of the cost never shows up as a line on the quote.

How to lower your window replacement cost

• Go with an insert when you can

  If your frames are solid and dry, an insert install saves about $330 per window over full-frame.

• Stick to standard styles and sizes

  Double-hung and sliding windows in common sizes are the best value. Specialty shapes cost more and take longer.

• Choose vinyl or fiberglass over wood

  You get most of the performance of wood for far less money and far less upkeep.

• Do the whole house in one project

  Bundling windows spreads the trip, setup and permit costs, and larger orders often earn a discount.

• Book in late fall or winter

  Installers are less busy in the off-season and more flexible on price. Insert installs work fine in cold weather.

• Get three itemized quotes

  Line-by-line quotes are easy to compare, and they keep everyone honest about what's included.

• Check rebates and the tax credit rules

  Some utilities offer rebates for ENERGY STAR windows, so check your utility's website. The federal Energy Efficient Home Improvement Credit, which covered up to $600 a year for qualifying windows, ended for windows installed after December 31, 2025.

How to compare window replacement quotes

Two quotes for "the same windows" can be thousands of dollars apart, and lining them up item by item shows you why. A good quote spells out:

• The brand, series and frame material
• The glass package, with its U-factor and SHGC
• Insert or full-frame installation
• Interior and exterior trim work
• Removal, disposal and permit fees
• Lead-safe work if your home was built before 1978
• Product and labor warranties, in writing
• The start date, the schedule and the payment terms

Red flags

• A price that's only good if you sign today
• A big discount off an inflated "retail" price
• One total with no breakdown
• Pressure to pay a large deposit up front
• Vague answers about who will do the installation

From Bobby's experience

A few things I learned on the job that never show up on a price list.

• The opening matters more than the upgrade. On a lot of jobs, what decided the final price wasn't the window. It was a soft sill, an out-of-square frame or old paint that needed lead-safe handling. Ask your installer to check the openings before you choose options.
• Inserts are underrated. If the frame is solid and dry, an insert install is the right call more often than many salespeople suggest. You keep your trim and save real money with no downside.
• Ask who's holding the drill. Plenty of companies sell the job and hand it to a subcontractor. The crew matters more than the logo on the brochure, so ask who installs and how long they've done it.
• Down South, fight the sun first. Here in Louisiana, glass that blocks solar heat did more for my customers' comfort and power bills than adding a third pane ever did.
• Measure before anyone comes out. When you know your counts and sizes, every quote is easier to compare, and nobody can pad the order.

How this estimator works

The estimator adds up four parts for every window you enter: the window itself, installation labor, materials and trim, and the options you choose.

• Window price starts from a typical 2026 price for each style in a mid-range vinyl version. It then adjusts for frame material, glass, quality level and size. Larger windows cost more, but less than in proportion to their glass area.
• Labor starts from a typical installed rate for each style, then adjusts for full-frame work, upper floors and heavier glass.
• Your state adjusts labor the most and materials a little, based on regional differences in construction wages and living costs.
• The range reflects normal differences between companies, brands and job conditions. Most quotes for the project you describe should land inside it.

The numbers come from a cost model built on typical 2025 and 2026 window and labor prices, checked against my years in the trade. Prices were last reviewed in October 2026. An estimate is a planning number, not a quote. Rotted framing, tricky access, local permit fees and sales tax can all change the final price.
