Basement window prices in this guide include windows designed specifically for basement use, both new construction and replacement basement windows. In exposed walls of a walkout basement or with the use of window wells, any type of window can be installed in a basement. For more information on those types of windows, see our guides to Double-hung windows, Casement windows and other popular types.
There are four basement window types to consider for your home. Basement window prices for each are found in the table below.
Basement Window Prices for 2019/2020
The following table provides an overview of prices and costs for basement windows by type, including prices for installation and supply only.
|Basement Window Prices and Costs|
|Window Type||Unit Price (Supply Only)||Unit Price (Including Installation)|
|Hopper / Awning||$45-$500||$195-$1,000|
Hopper / Awning Basement Windows
Hopper/awning windows are small and installed above grade or possibly with a shallow window well. Most have vinyl frames, but steel and aluminum frames are made too. These most popular basement windows can be installed in either direction. If the window is set with the hinge at the bottom, so the sash tilts inward and down, it’s called a hopper basement window. Reversed, with the hinge at the top, it’s an awning basement window. Most awning and hopper basement windows are supported by metal arms, though those that only function as hopper windows might have chains instead of arms. These basement windows are opened with a locking handle at the center of the sash.
Height range: 14” to 23”
Width range: 22” to 38”
Options: Clear glass is common, but frosted or textured glass is a good choice for privacy. Shatterproof security glass is a custom upgrade. Vinyl frame color choices are available on high-quality hopper basement windows.
Pros and cons of hopper/awning windows: These windows lock tight for security and to seal out moisture and weather. They are too small for most adults to fit through, so security is good. Those with double-pane glass are energy efficient, and vinyl insulates better than metal. Hopper windows offer better ventilation than sliding windows of the same size. Because the windows are small, they offer a limited amount of natural daylight. Cheap hopper windows will develop hardware problems sooner than quality windows will. When positioned as an awning window, they are slightly more susceptible to rodents, insects and rain entering through them.
Sliding Basement Windows
Sliding basement windows have one fixed side and one sliding side. Sliding windows lock where the sliding sash closes. Both left-slide and right-slide basement windows are produced. These are not egress windows. Sliding egress windows are discussed below.
Height range: 14” to 24”
Width range: 30” to 36”
Options: Glass options include clear (standard), privacy or frosted and security glass. You have color choices with some brands of vinyl sliding basement windows.
Pros and cons of sliding basement windows: These windows are the most affordable standard basement windows. On the negative side, the frames allow in less natural light than hopper windows of the same size, and the track the sash glides in will need to be cleaned regularly to ensure smooth sliding. The locking clamps on cheaper windows are prone to wearing out and becoming difficult to open and lock closed.
Glass Block Basement Windows
These are fixed window created from glass blocks in a steel frame. While they allow daylight in, glass block windows distort visually, like a warped lens, so you can’t see clearly through them.
Height range: 9” to 72”
Width range: 16” to 76”
Options: Several styles of glass are used including frosted and textured. Many glass block windows have a small hopper window as part of the construction for ventilation.
Pros and cons of glass block basement windows: The size range of glass block windows is much greater than hopper/awning and sliding windows. They are harder to break through than the other types too. Those without ventilation windows have no moving parts that can malfunction. Of concern are the higher cost of the windows and, as noted, the lack of ventilation with some glass block windows.
Egress Basement Windows
These windows are typically installed along with a window well for getting out of the basement if the stairway is blocked. Basements with bedrooms must have at least one egress window. Check with your local building department for details on what is required in your community.
Height range: 48” to 72”
Width range: 28” to 60”
Options: Egress windows come in casement and sliding styles. Glass options including double-pane and frosted glass are offered on some models.
Pros and cons of egress basement windows: Casement styles require a narrower opening, but they also allow in less daylight. They use a crank that might wear out with time and make the window difficult to open in an emergency. Sliding windows have a track that must be kept clean for smooth operation. A concern about egress windows as a whole is that they can be used to break into a home.
Factors that Affect Basement Window Cost
The wide spectrum of prices is due to the range in quality from quite cheap to outstanding. The size of the window and glass options account for the remainder of the price fluctuations, especially with block windows. On the installation side, who installs the window is the biggest variable. A general handyman service will charge the least, but quality might suffer, and some handymen are not insured for your protection if something goes wrong. The best way to get quality installation at the lowest cost is to request written estimates from several reputable, licensed and insured companies that know they’re competing for your window installation work.
