We’re going over the factors that influence the cost of window replacement, including various window types, the difference between DIY and professional installation, and how to tell when it’s time to replace your windows.

The Role of Windows in a Home

Windows let natural light into your home and provide views of the outside world. But they also play other important roles, such as providing ventilation, serving as fire escapes, and enhancing the overall appearance of your home.

Energy-efficient windows help you save money on heating and cooling costs, so it’s vital to have windows that are in good condition. 

The Value Proposition of Window Replacements

Do new windows pay for themselves in energy savings? The answer may depend on the window replacement cost and the difference between your new and old windows. 

If you live in a cold climate, windows with a high Energy Star rating can quickly save you money. And no matter where you live, new windows can make your home more comfortable and aesthetically pleasing as soon as they’re installed.

Factors in Calculating Window Replacement Cost

Size and Dimensions of the Window

The size and dimensions of your window help determine the cost of the window. Take a look at these window prices by size and dimension, not including installation:

Window dimensions Average cost to replace windows
Small (up to 36” either side) $70 to $255
Medium (up to 48” either side) $150 to $1,000
Large (greater than 48” either side) $450 to $3,000

Material Used

Windows are made from different materials, including aluminum, vinyl, fiberglass, and wood. Here are the average window replacement costs, not including installation.

Window materials Window replacement costs
Small aluminum $65 to $135
Medium aluminum $150 to $400
Large aluminum $430 to $530

Small wood $185 to $290
Medium wood $300 to $1,500

Glazing and Insulation Features

The most inexpensive type of window is a single pane. With various types of glazing, windows are much more energy efficient, and insulation features can make your windows more cost-effective and sound-proof, adding to the comfort of your home.

Windows are glazed in various ways, but the most common types of glazing include:

  • Single-pane
  • Double-pane
  • Triple-pane
  • Low emissivity (Low-E)

Sometimes, people confuse glazing features with the sash features. There is a difference between double-pane windows and double-hung windows. 

Labor and Installation Complexity

Window installation cost varies, ranging from $150 to $4,000. The cost depends on several factors, such as the labor rates in your region, the size of the window, and the complexity of the installation. For example, large window installations on a second story take longer than small ones on the ground floor. 

Additional Costs and Considerations

Window Replacement

Window Frame Repairs or Replacements

The cost to repair window frames depends on the materials it’s made from, how large the window is, and the extent of the damage. Broken window panes are usually the easiest to repair, but in some cases, it’s smarter to replace a window than repair it.

Minor repairs can be as low as $65 per window, but extensive damage to large windows can be as high as $1,400.

Disposal of Old Windows

When you obtain a quote for window replacement, be sure to inquire about the disposal of old windows. Some contractors will dispose of old windows without charging you extra, while others may charge a fee per window. 

Many recycled building material companies will take old windows, and some of them will even pick them up from you for free. 

Customizations and Specialty Glass

Custom windows cost an average of 25% to 75% more than standard windows, depending on the customization. Common types of specialty glass include patterned, laminated, and safety glass.

Potential Home Structural Modifications

Replacing a window is usually pretty straightforward. The old window is removed, and a new one of the same size is installed. 

However, if you want to install a different size or put a window in a wall where there wasn’t one before, it can cost considerably more to make the structural modifications required, including adding new wall studs and fixing the interior wall and the exterior siding.

Replacement Costs by Window Type

Window Replacement

Take a look at the various costs of replacing different types of windows.

Single Hung Windows

Single-hung windows are one of the most common types of windows used in homes in the United States. They consist of two window panes, one of which is fixed in place and another which moves up and down.

Sometimes, single-hung windows are installed horizontally, so they slide open from left to right. However, this often results in moisture issues and isn’t a preferred method in certain climates. 

Features and Price Range

The cost to replace a single-hung window averages $150 to $400 per window, depending on the size, materials, and installation costs.

Double Hung Windows

With double-hung windows, both the top and bottom panes can move up and down vertically. They cost more because they have more moving parts and require more materials to produce.

Features and Price Range

The average cost for window replacement for double-hung windows is $200 to $600, depending on the size, materials, and installation costs.

Casement Windows

Casement windows are another popular type of window. They open vertically, often by a hand crank mechanism or on side hinges.

Benefits and Typical Costs

Casement windows allow for full ventilation, so they’re often used in places like over the kitchen sink. The cost to replace or install a casement window is $600 to $1,400, making them one of the more expensive window replacements.

Bay and Bow Windows

Both bay and bow windows project outward from the exterior wall of the home. Bay windows have three sections, while bow windows have multiple sections and are more gracefully curved.

Design Benefits and Cost Factors

Bay and bow windows provide more light within the window structure. They typically offer better views, and they enhance the appearance of your home.

The average cost of bay window replacement is about $2,500. Bow windows are a little more, typically costing about $2,800. However, custom-designed bay and bow windows can cost as much as $13,000, depending on the size, materials, and installation. 

Reasons Why You Should Replace Windows

How can you tell when it’s time to replace your windows? On average, the lifespan of a window is 15 to 20 years, but they often need to be replaced or repaired before that.

Energy Efficiency Improvements

Many older windows installed even as recently as 20 years ago are not as energy efficient as windows made today. As technology improves, the energy efficiency ratings of windows continue to increase, and the savings in energy costs are a common reason to replace windows.

Enhancing Home Value and Curb Appeal

New windows are aesthetically pleasing, enhancing your home’s curb appeal and increasing the value of your home. Over time, the color of your windows starts to fade. If they are painted, the chipped or peeled paint can look bad, and replacing your windows is a good way to give your home a fresh, updated look.

Functionality and Operational Issues

Windows start to freeze up when they age, and you may have other operational issues that make them difficult to use. Here are the most common problems with old windows, in terms of functionality:

  • Water and air leaks
  • Sticky window operation
  • Foggy windows
  • Damaged frames and screens
  • Noise penetration
  • Broken panes

Safety and Security Concerns

If your old windows aren’t working correctly, they can make your home more vulnerable to intruders and prevent them from being used as a fire escape.

New windows not only make your home more aesthetically pleasing, but they also provide increased safety and security.

Weighing Costs, Time, and End Result Quality
