How Much Does It Cost To Install Sliding Window?

Homeowners need to pay between $750 and $1,350 to replace a single sliding window, with the average coming in at around $900 for a 48” x 36” sliding window with double aluminum siding and double-pane glass. At the low end of sliding window installations, a 36” x 24” vinyl sliding window should cost about $550. On the higher side, homeowners should budget up to $2,300 to install a triple-pane fiberglass sliding window that measures 60” by 48”. Final costs depend significantly on material, size, and added features.

Sliding Glass Window Cost by Size

The window’s size is the most important cost factor for sliding window 1 installation. A small sliding window price for a 24” by 24” window starts at just $130. However, a larger 48” by 48” sliding window cost may reach $650. At the top end of the scale, a 96” wide window installation may cost up to $2,300. This chart lists common sizes and the average cost. When sizing windows, you may notice measurements like 23½” x 47½”. These are the window’s actual measurements, designed to fit into a 24” x 48” opening. Round the measurement up to see the size. It is worth noting that some manufacturers price their windows by square foot. Expect an approximate cost of $3.45 per sq. ft. for basic windows installation, $4.38 for mid-range windows, and $5.67 for premium windows installation. The costs listed in the table below are for the glass without installation. Costs are based on the cost of the parts of a standard double-pane window, not including installation:

Sliding Window Price by Type

There are 3 main types of sliding windows for homes. A single window has two sides, called panes, and one pane slides left and right to open. The average cost for a window installation with a single slider is $300 to $750. They are the easiest sliding windows to acquire. The majority of sliding window installations feature single sliding windows. A double window also has two panes, and both slide left and right to open. The average cost of a double slider is $360 to $900. Double sliding windows cost more because they have more moving parts and are more complex.

The largest option is a triple window, with a fixed central pane and a panel on the left and right that slides open. Costs for triple windows cost range from $5000 to $3,000. Triple sliding windows generally need a lot of room, so they are best on large walls. When selecting a type of sliding window to install, consider the window’s size, available space, slider type, and budget. Here are the average prices for different types of sliding windows, not including installation, and based on a window with a minimum width of 48”.

Cost To Install Sliding Window
TypeAverage Cost (Unit Only)
Single$300 – $750
Double$360 – $900
Triple$500 – $3,000

Sliding Window Frame Price by Material

Homeowners usually choose wood because of its visual appeal. Fiberglass is a choice for homeowners who want long-lasting windows. Aluminum is very lightweight but only appropriate for homes in areas that do not experience large temperature swings. Aluminum-clad windows are an option for homeowners who want a wood frame with a little added protection or sturdiness. Composite windows are another long-lasting option people choose when they want the appearance of wood in a long-lasting format. The following table will assist you in the cost of the sliding window installation project based on the material you choose for your window. Material costs are based on an average 48” x 36” window.

Cost To Install Sliding Window
MaterialCost (Unit Only)
Vinyl$400 – $800
Composite$400 – $1,350
Wood$325 – $1,500
Aluminum$500 – $900
Aluminum-Clad$600 – $1,000
Fiberglass$800 – $1,400

Sliding Window Glass Price by Type

The type of glass in a sliding window also affects the cost. Typically, a window has 1 to 3 panes, which insulate the house. Some manufacturers seal the panes with gas inside or treat the glass with special coatings. In general, the more panes of glass or the more coatings, the less heat goes through the window. It is very helpful for climates with extreme temperatures because better insulation means lower heating and cooling costs. Many enhancements can be combined, such as low-E glass and double-pane argon-filled windows. Use the table below to gauge the cost of various glass types and help you budget your sliding window installation. Costs are based on a standard 48” x 36” window.

Cost To Install Sliding Window
Glass TypeCost (Unit Only)
Single-Pane$250 – $550
Double-Pane$350 – $650
Reflective Glass$450 – $750
Low-E Coating$475 – $720
Spectrally Selective Coating$475 – $820
Argon-Filled$495 – $930
Triple-Pane$550 – $1,000
Krypton-Filled$625 – $1,390

Single-Pane Sliding Windows Cost

You can expect to pay between $250 and $550 for 48” x 36” single-pane windows installation. Single-pane windows have only one sheet of glass in each frame. They are the most basic type of window on the market, which makes them less expensive. 

Double-Pane Sliding Windows Cost

Double-pane windows cost $350 to $650 for a 48” x 36” window installation. Double-pane windows have two layers of glass in each frame. These double-pane sliding windows insulate much better than single-pane windows, and the space between them can be treated with insulating gases, such as argon and krypton, or special coatings. However, lower-quality windows can develop leaks and get mold or other materials between the panes.

Reflective Sliding Window Cost

Reflective-coated windows installation usually costs between $450 to $750 for a 48” x 36” window. A reflective coating is a treatment applied to the glass panes in a window installation. This coating reflects part of the sun’s rays to improve the home’s energy efficiency during the summer. This gives the glass a tint like sunglasses.

Sliding Argon Gas Windows Cost

Sliding argon gas-filled windows cost $495 to $930 for a 48” x 36” window. Argon gas is a non-toxic gas similar to helium but denser. The density of argon makes it a better insulator. Many double-pane sliding windows use argon gas between the panes. If one of the panes breaks, the gas will be lost, and the entire window needs to be replaced.

Framed vs Frameless Sliding Windows

In most cases, frameless windows feature double-pane construction because they do not have sliding window material surrounding the frame that helps provide insulation. However, frameless windows still require some structural support within the wall to support the weight of the window. Homeowners should be prepared to pay more for the windows, installation, and labor. The table below offers approximate costs for frameless windows versus framed windows for a 48” x 36” window.

Cost To Install Sliding Window
TypeCost (Unit Only)
Framed$250 – $600
Frameless$500 – $2,250

Sliding Window Installation Cost

Average labor rates for building contractors are $55 to $105 per hour. Smaller windows can be installed in 2-3 hours, while larger windows may take 6-8 hours. Homeowners can estimate the total cost based on the cost of the window they select plus the estimated cost of labor. For example, a 48” x 36” double-pane window may cost $350 to $650 and have an estimated installation cost of $290 to $780. The total cost for the window plus labor costs ranges from $570 to $1,430. Tasks like making a new hole in the wall push the cost to the higher end of the range. Installations into an existing window frame take less time and cost less.

Sliding Window Replacement Cost

Replacing an existing sliding window is much easier than installing a new window. For small or medium-sized windows, expect to pay $180 to $510 in labor. Depending on the window’s size, it may take a crew 2-3 hours or a single laborer 4-6 hours. Complex installation jobs that require extra time increase the installation cost by $90 to $340. Difficult removal of old windows increases the cost by $45 to $85 for each additional hour required to remove the old window.

Cost To Install Sliding Window
NumberLabor Cost per Window
1 – 4 Windows$190 – $600
5 – 9 Windows$200 – $580
10 – 19 Windows$200 – $550
20+ Windows$190 – $520

Cost to Replace All Sliding Windows in a House

Some homeowners replace individual windows for homes as necessary. It is possible to replace all the windows in the house in one job. Major restorations often feature larger projects. However, it is always up to the homeowner whether to replace them individually or all at once. The average home has approximately 22 windows, but smaller homes may have around 15. Large homes may have up to 30 windows or more. With these averages in mind, here are the costs you might encounter in replacing all the windows in a house. The low end of the cost represents single-pane windows installation, and the high end of the range represents triple-pane windows installation.

Cost To Install Sliding Window
NumberReplacement Cost (Installed)
15 Windows$5,500 – $19,750
20 Windows$6,900 – $25,400
25 Windows$8,500 – $31,500
30 Windows$10,00 – $37,600

Casement vs Sliding Windows Cost

A sliding window, sometimes called a gliding window, opens by sliding left or right in a track. A casement window 5 opens by swinging on a hinge, often using a crank. Casement windows; are more complex and cost an average of $650 to $1,800 to install. These windows have more moving parts, which add to the total cost of ownership. Casement windows are also limited in size and rarely more than 36” wide. However, despite their limitations, casement windows are more efficient than sliding windows because they make a full seal when closed. A sliding window is on a track where air transfer can occur.

Sliding windows cost an average of $750 to $1,370 to install, which is quite close to casement windows. The similar price means that homeowners need not base their decision on cost, focusing instead on the functionality of casement versus sliding windows. Overall, sliding windows installation is easier to operate and maintains a lower ownership cost with fewer moving parts. Sliding windows can also accommodate very wide openings, with sizes up to 60” wide. The table below shows the average cost to install casement versus sliding windows.

Sliding Window vs Double-Hung Cost

 A sliding window may let some air in or out of the residence along the edge of the trough where the window slides open or closed. One of the additional benefits of double-hung windows is that parents can open them at the top, which reduces the likelihood of a child falling out of the window.

On the other hand, a homeowner may choose a horizontal slide window because of its ease of operation versus a horizontal window. Modern windows are so fluid that all it takes is a featherlight push to open or close them. Sliding windows are also easier to obtain in large sizes, which is helpful for homeowners who want a large window that they can open to the outside. For many homeowners, the choice of a vertical or horizontal window comes down to aesthetics. They have their differences, but each creates a distinct look for the home.

Cost To Install Sliding Window
Type of WindowAverage Cost (Installed)
Double-Hung$650 – $4,000
Sliding$750 – $1,500
