While the average window replacement cost is between $200 and $1,800 per window, this doesn’t take into account the unique features of your house or the different types of windows currently available.

In this guide, we’ll break down average window replacement costs by the framing material, type of window, and other considerations so you can form a better picture of how much money it costs to replace a window.

How to Calculate the Cost of a Window Replacement

As you budget for replacing your windows, decide what type of framing material you want. Pick a material that matches the interior decor of your home and provides proper insulation for the climate you’re in. You’ll also want to consider the number of windows you want to replace. Finally, take labor costs into consideration, as professional installation is recommended.

After budgeting for your window replacement project cost, consider these options to save more money:

  • Select windows labeled as “contractor-grade” or “builder-grade” from major window companies—these will be high-quality but less expensive than “architecture-grade” windows.
  • Stick to standard window styles and shapes without extra features that you might not need or use, as these will be cheaper than custom windows.
  • Get multiple quotes from professional window installers to negotiate a reasonable price.

Factors That Affect Window Replacement Costs

Two of the most important factors that affect the cost of a window replacement are the material of the window frame and the type of window, which we’ll discuss in the next few sections. Here are a few other important factors that will affect the cost of a window replacement:

  • The location of your windows determines cost, as windows on the ground floor of any building require less labor to replace than basement and upstairs windows.
  • The age of a home can increase labor costs, as older homes can come with non-standard window sizes and structural issues that require more careful installation.
  • Window frames that need additional insulation and weatherproofing will cost more.
  • Beyond just the style of a window, the type of glass itself can affect the price. Double-pane windows, which have two layers of glass, are more expensive than single-pane windows, but they block sound, heat, and cold air much more efficiently. Tinted, tempered, and safety glass are all a bit more expensive than standard glass, and larger or unusually sized windows will incur additional costs.
  • Replacing the windows in a home is less expensive than installing them during new construction. Using retrofit window replacements instead of full-frame windows, which contain a nail fin that your house already features, will save you substantial money.

How Much Do Different Types of Windows Cost?

In addition to framing materials, the type of window affects the cost of a window replacement. Below are the most common types of windows and their associated replacement costs.

  • Picture: Picture windows, sometimes called fixed windows, are made of just one sheet of glass in a frame that doesn’t open. However, picture windows often have unique sizes and shapes, which means you might need a custom window that can vary between $80 and $800 to install.
  • Single-Hung: A single-hung window consists of an upper pane of glass that’s fixed in place and a lower pane that slides up and down or swings inward. These are popular, low-cost windows, though they’re typically found only on ground floors. The cost to install one of these windows typically ranges from $100 to $400.
  • Double-Hung: A double-hung window is similar to a single-hung window, except the top sash can slide down or swing open. These are slightly more expensive than single-hung windows and cost between $150 and $650 to replace.
  • Bay and Bow: A bay window typically consists of three large panes of glass in an angled frame that extends out from the side of the house. Because of the size of the glass, these windows are typically quite expensive to replace and can cost anywhere from $500 to $2,500. Similarly, bow windows consist of at least five large panes of curved glass and will typically cost at least $1,000 to replace.
  • Casement: Casement windows open using a hand crank, typically on a left-to-right axis. Depending on the size of your casement window, you’ll pay between $150 and $1,000 for a window replacement. A casement window with a hinge at the top, called an awning window, costs between $420 and $760 to replace.
  • Glass Block: Windows composed of glass blocks are most common in bathrooms, since they let in light while offering some privacy. Again, size and shape will play a large role in glass block window replacement price, which is typically in the $400 to $1,100 range.
  • Sliding: Sliding windows are essentially single- or double-hung windows that open horizontally instead of vertically. The replacement cost for standard-sized sliding windows will range from $150 to $600, but the replacement cost for full-size sliding glass doors ranges from $1,000 to $2,500.
  • Skylight: As you might expect, skylight windows are expensive to replace due to the relative difficulty of installation. Depending on your skylight’s size, shape, and how it opens, expect to pay anywhere from $900 to $2,400 for a skylight window replacement.
  • Storm: Storm windows are panes of glass that are installed inside or outside existing windows to protect the window and provide further insulation. They can be permanent or removable. A single storm window isn’t that expensive and usually costs between $150 and $450 to replace. However, homeowners typically opt to protect all of their home windows, costing around $5,000.

How Much Do Different Window Framing Materials Cost?

The framing material of a window is just what it sounds like: the structure between the glass of the window and the walls around it. This material determines the look of a window, its energy efficiency, how easy it is to maintain, and its cost.


Vinyl window frames are the most common, given vinyl’s durability and affordability. This PVC material is a good insulator and thus makes for an energy-efficient window. Vinyl is also the most low maintenance option available. It isn’t the strongest or most aesthetically pleasing option, but it is budget-friendly. Vinyl windows typically cost between $100 and $900 to replace, but the average replacement cost is between $400 and $600 per window.


A strong and lightweight metal, aluminum is a popular choice for window frames because of its resistance to bending or warping. Unfortunately, it’s not a good insulator, so it makes for a less energy-efficient window. In general, aluminum window frames cost around $275–$1,285.


Wood windows provide a classic look, which is usually the reason homeowners choose wood as a framing material. Functionally, wood doesn’t expand or contract with heat, and you can repair individual parts of the frame rather than needing to replace the entire window. However, you may be stuck with multiple repairs in the future, since wood can crack, peel, and warp.

Depending on the type and quality of the wood, wood frames can cost anywhere between $150 and $1,300 per window, though the average is around $600 to $700 per window.


Made of a mixture of wood fibers and polymers, composite window frames are some of the most durable. They’re as energy-efficient as vinyl, lowering energy bills by insulating window openings, but they’re a little more expensive than wood, costing $300 to $1,300 per window.


Fiberglass window frames combine the energy efficiency of vinyl with the sturdiness of aluminum, and they’re available in an appearance that mimics painted wood. The drawback, however, is that they tend to be more expensive than any of the other listed materials, as the cost to replace a fiberglass window is between $500 and $1,500.

What Are the Labor Costs for Window Replacement?

Along with the costs of the windows, you need to factor in the cost of labor. We recommend choosing a professional installer for your replacement project in most cases. Homeowners can expect to pay an average of $100 to $300 per regular window installed or an hourly rate of around $38 to $40.

More complicated installations (including oversized and specialty windows) will add to the labor costs. These costs could rise to $800 to $1200 per window installation. While a standard installation would take about an hour, large jobs could run for six hours or more.

How Does Window Location Affect the Cost?

The location of your windows can add to the expenses of a window replacement project. For example, the costs for windows in the foyer, bathroom, or bedroom will stay relatively low because they use standard size windows. However, your costs will increase as you update rooms with multiple specialty or decorative windows (i.e., kitchen or living room).

Basement window replacement costs depend heavily on the type of window you choose. Replacing basement windows can cost between $200 and more than $1,000. However, if you choose to install basement egress windows for a basement bedroom, your costs will increase to the $2,000–$5,000+ range. Egress windows are specialty windows that are large enough to use to escape during an emergency. These windows usually require a professional for the installation.

You can also expect additional costs for windows on the upper floors. Those installations require additional labor costs, special equipment, and more time to complete the project.


Energy-Efficient Options for Replacement Windows

If you are looking for ways to lower your energy bills, there are several ways to help improve your home’s energy efficiency with the right replacement windows or glass type.

Energy-Efficient Windows

Single-pane windows are the most basic type of windows used in homes. As the name suggests, these windows use a single layer of glass. They do not provide insulation or energy efficiency protection for your home. The outside temperatures seep through the windows and affect your home’s internal temperature. Single-pane windows cost less, making them the best option for a strict budget, with average costs around $100 to $350.

Double-pane windows offer better energy efficiency by using two panes of glass with gas trapped in between the panes. The gas used, typically argon or krypton, is nontoxic, colorless, and odorless. Double-pane windows use this gas as insulation, helping to trap frigid cold or sweltering heat without affecting your home’s internal temperatures. You can expect to pay between $400 to $900 for each window installed in your home.

If you need additional protection, you can install triple-pane glass windows with three glass panes. They cost the most out of the window options, with pricing from $500 to $1800 per window.

To maximize your energy savings, you can install replacement windows that are Energy Star certified. These products are backed by the U.S. Environmental Protection Agency (EPA) for their cost-saving energy efficiency.

According to Energy Star, using these certified windows in your replacement project will lower your household energy bills by 12% annually, on average. By upgrading your non-certified products, you can save $101–$583 a year for single-pane windows and $27–$197 annually for clear, double-paned installations.

Energy-Efficient Window Treatments

In addition to using energy-efficient windows, homeowners can opt for glass with special coatings that block ultraviolet (UV) rays. Low-emissivity coatings (or Low-e) help control how heat energy moves through the panes. Low-e coatings on the exterior of the glass will prevent heat from passing into your home without blocking the sunlight.

Tinted windows are an alternative to Low-e windows that use solar window film to block UV rays. They are similar to car window tinting but are less noticeable and don’t take away from the aesthetics of your home.

Retrofit Replacement Cost vs. Full Frame Cost

Homeowners can keep costs down for their replacement windows project by opting for retrofit installations. This type of installation uses the existing window frame and trim and only involves removing the window sash. A retrofit installation can reduce window installation costs by 10–15%.

However, if you choose a full-frame installation instead, your overall cost could double. The window sash, trim, and frame are removed and replaced with new parts during this installation process. After the installation, the window frame and trim must be stained to match the existing trim. See a breakdown of window parts below, as illustrated in our How to Replace a Window article.

How to Save Money on Replacement Window Costs

You have several options to help lower the cost of window replacement. Homeowners should begin by contacting their local utility company for any rebates and incentives available. These credits are limited to Energy Star or energy-efficient windows that have been professionally installed. You may also receive additional rebates from the window installer companies.

Some states offer tax credits and rebates for energy-efficient home improvements, including windows. You should check the Database of State Incentives for Renewables and Efficiency (DRISE) for available incentives in your state.
