Window Installation Cost

Windows enhance your home's natural light and are an important energy-saving investment. New window installation costs an average of $6,399, or between $2,982 and $9,817. The number of windows, type of window, and labor all impact the total price. For example, a single-window unit runs $300 to $1,200 for standard sizes, while custom and bay windows cost $2,110 on average. 

Compare quotes from local window installers for the best price. Keep in mind that labor typically costs $150 to $800 per window or about $40 per hour. Let’s walk through the basics of new window installation—including frame material, size, brands, and other factors—to help keep your home energy-efficient and comfortable

2022 Notice: Material Prices are Surging

Demand for windows has grown over the past year. And, as a result, manufacturers are increasing materials prices. Prices have gone up 5% to 10% this year, and many parts of the country are experiencing long delivery times. If you're planning a window installation or replacement project, we recommend starting as early as possible in the season, preparing for potential price fluctuations, and allowing extra time to order materials.

Window Cost by Frame Material

The material you choose for the window frames affects the price as much as the style. Vinyl is the most common type, closely followed by wood. Other types include composite, aluminum, and fiberglass.

Material Average Cost
Vinyl $250 – $600
Wood $600 – $2,000
Fiberglass $600 – $900
Aluminum $400 – $1,200
Composite $300 – $1,100

Vinyl Windows 

Vinyl windows cost $250 to $600 and require little maintenance. They're also extremely durable; changes in humidity don't cause them to swell or shrink. Most manufacturers stand behind their products with strong warranties, sometimes even lifetime warranties. Their greatest drawback is that they're not as sturdy or attractive as wood.

Wood Windows

Wood frames cost $1,300 on average and require regular maintenance. If you fail to repaint and finish wood units, they become susceptible to the elements.

The work and money can be worth it for wood's classic, authentic, and architectural appeal. That's why some historical neighborhoods have covenants requiring wood framing.

Fiberglass

Fiberglass units cost an average of $750 each, including installation. This material is more durable than vinyl with similar insulation properties. It is less common because of its price.

Aluminum or Metal

Aluminum can range anywhere from $400 to $1,200 or more for large or high-end varieties. Though aluminum is still available, it's far less popular than other types since it's tough to paint, doesn't insulate well, and typically costs more than vinyl or composite.

Composite

Composite windows cost between $300 and $1,100. This style attempts to capture the best of both worlds by mixing PVC polymers with wood fiber to create a strong, attractive frame.

Window Installation Cost by Type

The type of windows you want to install impact cost because of the amount and type of materials used and how complex the windows are to fit correctly. Fixed, single-hung, and double-hung windows are the most common and least expensive, while custom, bow, bay, and egress windows cost the most.

Type of Window Installation Cost Range (All-In) Average Cost (All-In)
Single-hung $100 – $400 $250
Basement $50 – $650 $350
Fixed or Picture $65 – $700 $380
Double-hung $150 – $650 $400
Bay $600 – $250 $420
Sliding $150 – $800 $470
Casement $150 – $1,000 $570
Egress $2,500 – $5,400 $4,000
Bow $1,000 – $4,500 $2,700
Custom $500 – $13,000 $6,700

Insulated, Energy-Efficient Window Costs

Thermally-insulated, energy-efficient windows run anywhere from $120 to $1,200 or more. Labor adds $200 to $800 each. Usually, the higher the price, the more energy-efficient the windows are. You will have a higher initial investment, but you will save on energy costs in the long run, depending on your climate. 

"Casement windows are the most energy-efficient style you can buy (aside from fixed windows). This is because the units have a strong seal on all four sides when closed, which keeps air out,” says Cati O’Keefe, Expert Home Building & Sustainability Contributor. “Consider using these windows on areas of your house that are not protected by roof overhangs, the topography of your site, or trees."

Replacing windows for better thermal insulation with Energy Star-rated varieties helps you save on your utility bills and may help you qualify for local or federal energy rebates.

  • Windows account for 25%–30% of your home's heat loss.

  • Low-E coatings add 10%–15% to the cost but reduce infrared heat in the summer, lowering your air conditioning bill.

  • Vinyl, wood, and fiberglass are much better insulators than aluminum.

Any frame material type or design can include high-efficiency glass and Low-E coatings. Talk with your contractor to determine which type suits your climate.

Cost to Install Multiple Windows

The more windows you install at one time, the less you'll pay per window. Some window installers offer special deals, such as “install three, get one free.” Some offer packages, like a special reduced per-window price if you have all of the windows replaced on one side of your home or one floor. 

Installing multiple windows can reduce labor costs per window and minimize travel time, cost, and waste disposal.

Window Costs by Brand

There are many window brands specializing in certain styles, types, or frame materials. While cost ranges widely (even within the same brand), you'll find that some focus on affordability and mass production while others focus on high-end, custom installations.

Window Brand Price Range (All-In) Average Price (All-In)
Feldco $250 – $2,000 $1,100
Window World $350 – $2,000 $1,200
Alside $250 – $2,300 $1,300
Simonton $400 – $3,500 $1,900
Pella $250 – $3,800 $2,000
Anderson $365 – $3,800 $2,000
Marvin $365 – $4,800 $2,600

Average Labor Cost to Install New Windows

Labor runs $30 to $50 per hour. Most contractors bid at a flat rate with labor included, but you can estimate 1 1/2 hours for each basic project. Complex configurations, custom work, and older homes might require up to six hours each.

Other Window Cost Factors

There are many other factors to consider when planning a budget for new windows. Considerations like glass type, size, which floor of the house the window is going in, and many other factors impact the total price.  

Glass Type

Glass type impacts both the installation cost and long-term energy costs. Single-pane windows are the least expensive but have the worst insulating properties, so they cost the most in terms of energy use and carbon footprint. Double-pane windows cost more to install but cost less in energy wastage.

When comparing the pros and cons of double-pane windows, note that you can save up to 24% in cold climates during the winter and up to 18% in hot climates during the summer. You'll pay more for double-pane windows, but they will pay for themselves over time. A triple-pane window runs for 15% to 40% more than a double-pane one, but it further reduces heat loss.

Size

The bigger the window, the more it costs. Bathroom windows are often the least expensive, as they tend to be small, often sized at 1-1/2-by-2-by-3 feet. 

Living room windows are often more expensive because they're larger, and because this is where the family entertains or spends most of its time, these windows are decorative and functional. While a window can be any size, a standard picture window is often 6 feet by 6 feet. This is also where you'll commonly find bay or bow windows, which are large, tall windows made from multiple sheets of glass and are expensive to install.

Second or Third Floor

Be aware that units above the first floor may be more expensive because of access issues. The second floor and higher require additional equipment, such as scaffolding, ladders, and safety harnesses. Not only does the cost of equipment increase the price, but the project will also require more labor. 

Large Units & Window Wells

Window walls range from $700 to $1,600 per linear foot for the materials and installation. These are excellent additions to highlight views and scenery but require the right structural supports.

New Construction vs. Replacement

New construction windows run anywhere from $85 to $1,400. Designed for new construction and during remodels where the stud-framing is exposed, they attach directly to the studs via a flange called a nail fin frame.

Replacement windows cost $300 to $2,100 depending on the size, installation requirements, and material. Specialty types, such as glass-block and large-picture styles, can run upwards of $2,500 or more.

Full-Frame vs. Inserts or Retrofits

Full-frame windows are about 10% to 15% more than a retrofit style. Expect to pay an additional $50 to $100 per unit for installation prices.

  • Retrofit, also called inserts, uses the existing frame and trim for a quicker job.

  • Full-frame types require removing the old frame and putting in a new frame and trim. New trim requires staining after the installation to match your current trim.

Installing a Window in an Existing Wall

While you can expect to spend anywhere from $1,000 to $5,000, or more, per window, no two projects are the same. This type of work requires a combination of framing, siding, finishing work, and sometimes electrical and plumbing rerouting.

Factors that affect new installations in existing walls include:

FAQs

What's best for south-facing windows?

It depends on your climate. For example, someone in the North may want large, triple-panes to let as much natural heat in from the sun as possible. Those in a Southern desert environment may want smaller, high-efficiency windows with Low-E coating to keep as much heat out as possible.

Can I DIY add a new window to my house?

Check with your local code enforcement agency to see if this type of project is allowed in your area. While most jurisdictions allow you to DIY windows in your home, it may not be a good idea. Incorrectly installed windows can allow water into your home's walls, floors, and basement. A DIY installation can end up costing you more than a professional installation in the long run.

How do I know if I need a replacement or an entirely new window installed?

The best way to know if you need a replacement or new construction window is to ask a contractor to inspect your home. Over 80% of replacements use retrofit or slide-in types. But if significant damage to your walls, framing, or siding exists, you may be better off installing a new construction unit.

Are new windows installed from the inside or outside?

Your contractor can install your windows from either the inside or outside of your home. However, installing from the inside often helps homes in colder climates maintain interior temperatures and keep cold air out. The converse is true for homes in warmer parts of the country. Your window type also comes into play. If you have concerns or questions, ask your professional window installer.
