The Cost to Replace a Window Glass by Size

Pane size is the factor we should overview first as it determines the material cost and the labor intensiveness of the project. The size of a window glass is determined by multiplying the width and the height together. Usually, the cost to replace the glass will increase proportionally with the window size - the larger the window, the higher the replacement expense. Additionally, the thickness of the glass plays a crucial role in determining the overall window pane replacement cost that homeowners must keep in mind.

Note! If your frame is still in good condition, there is no reason to switch to a window pane of a different thickness. Go for the same thickness as you had before to save a bundle. 

Here is how much glass costs by its size. The mentioned costs are relevant for panes of ½-inch thickness. 

The Cost to Replace a Window Glass by the Number of Panes

The total expense associated with replacing broken window glass is determined by several factors, chiefly the specific type of window and the total count of damaged panes. Other variables, like the amount of damage, the nature and scope of the repair work, and labor costs, can also significantly impact the final price.

Let us examine how the number of panes affects the average glass window replacement cost.

Single-Pane Window Glass Replacement Cost

Generally, window contractors charge $50 to $260 to replace glass in a single-pane window. The cost may vary depending on the glass type and thickness. Flat, float, and plate panes are the cheapest, yet they have a reduced service life and poor energy efficiency. Coated, tempered, and low-E window glasses cost more but offer better durability and help to skimp on energy bills. 

Here are the average prices of window glass replacement for a single-pane window unit.

Double-Pane Window Glass Replacement Cost

The cost to replace glass in double-pane windows ranges from $200 to $600, depending on the size and configuration of the unit, as well as glass thickness and frame material. Thicker, more durable types of glass tend to cost more. In addition, the type of frame material used can also influence the overall cost, with certain materials like wood or fiberglass proving more expensive compared to others, such as vinyl or aluminum. These variable components, interacting with one another, contribute to the final cost you would incur when replacing the glass of a double-pane window.

Here are the average double-pane window glass replacement costs by window type.

Triple-Pane Window Glass Replacement Cost

The cost of replacing a triple-pane window glass lies within the range of $400 to $950. The triple-pane glass design incorporates three glazed layers, amplifying its energy efficiency and durability. As triple-glazed units reduce heat transfer significantly, they can lead to substantial energy savings over time, contributing towards decreasing your heating or cooling bills. 

Here is how the cost of glass replacement varies based on the type of triple-pane window:

The Cost to Replace a Window Pane by Window Type

Different windows come with varying complexities and features, like the number of panes and frame materials. That is why it's essential to evaluate every type of window separately to apprehend how their unique features may influence the cost of glass pane replacement. Below, we will discuss the expenses associated with replacing window panes for different types of windows, providing essential details that can assist homeowners in planning cost-effective window repair or replacement.

Storm Window Glass Replacement Cost

Most storm windows come with two or three panes as they require improved energy efficiency. Fixed storm units are often equipped with tempered glass while sliding with triple glass panes that slide on several tracks. Triple-pane storm windows offer the highest level of insulation and are particularly beneficial in cold climates. The cost of window pane glass in storm units varies from $100 to $480, depending on the type and quality of the glass, number of panes, size of the window, and whether it includes additional features such as UV-protective coatings, tinting, or insulated glass. 

Egress Window Glass Replacement Cost

Egress windows typically installed in basements and serve as an additional emergency escape generally feature single or double-pane glass. Double glazing is more favorable if the basement is used as a living space, as it helps prevent air leaks and keep a stable temperature. Some modern or high-end egress windows could also use triple-pane glass for enhanced insulation and noise reduction. Depending on the selected size and type of the pane, the cost of its replacement in an egress window ranges from $150 to $800. 

Casement Window Glass Replacement Cost

Casement windows typically come with double panes for optimal insulation and energy efficiency. They provide an unobstructed view of the outdoors and are known for their superior ventilation capabilities, as they can fully open to allow air circulation. The average casement window glass replacement cost varies from $100 to $580 for a standard-sized pane. However, the cost may rise to $1,000 for larger or custom-sized panes, depending on the type of glass and additional features. 

Skylight Window Glass Replacement Cost

Skylight windows typically feature double-pane or triple-pane glass to provide optimal insulation and limit heat transfer, which is essential as these windows are directly exposed to sunlight. Some skylights also incorporate special coatings to improve energy efficiency and decrease UV radiation. The average cost to replace glass in skylight windows varies from $250 to $700, depending on the selected glass type and coating. 

Picture Window Glass Replacement Cost

Picture windows customarily feature double or triple-pane glass. Due to their large size designed to provide an unobstructed view, these windows require thick, insulated glass to prevent energy loss. As panes are of non-standard, large size, the cost of their replacement is typically higher than other models. Generally, you should expect to spend from $200 to $1,100 to get replacement glass for your picture windows.

Bay Window Glass Replacement Cost

Bay windows typically feature double-pane or triple-pane glass. Double-pane glass is most common and provides a balance between efficiency and cost, but triple-pane glass might be chosen for even greater insulation, particularly in regions with more extreme weather conditions. When it comes to this type of window configuration, you should expect to replace all three glass panels, which usually cost from $400 to $3,950, depending on the glass type, size, and additional features. 

Bow Window Glass Replacement Cost

Bow windows are projected outward like their bay counterparts. Nevertheless, they are more rounded and have four to six panes. Most often, bow windows come with double-pane glass that ensures energy efficiency around the year. Depending on how many panes you need to replace in your bow window, the project cost will vary from $700 to $2,000. 

The Broken Window Replacement Cost by Glass Type

The total cost of replacing a broken window is tied to the type of glass used in the window's design. Fundamentally, costs can fluctuate depending on whether you are dealing with single-pane, double-pane, or triple-pane glass, each presenting a distinct level of complexity during installation. Moreover, the type and quality of coating applied to the glass, such as heat-absorbing tints or low-emissivity coatings, can also significantly influence the price due to their added benefits of reducing UV light. It's also worth mentioning that some more advanced types of windows come equipped with additional features, like special inert gasses between the panes. This multitude of factors contributes to a rather wide range of potential costs when calculating the expense of replacing a broken window.

Here is how much it costs to replace window glass by its type.

Labor Cost to Replace Window Panes

The window glass replacement process cannot be identified as simple or suitable for a do-it-yourself approach. It mainly has three stages - removing the existing pane, installing new glass in the prepared frame, and sealing it in place. Contractors also provide window inspection services and debris cleanup. The whole process takes up to an hour for one pane and requires an ability to handle tools like a screwdriver, chisel, and putty knife. The average labor cost to replace a window pane varies from $90 to $160 one pane. You can expect a discount for replacing multiple panes at once.
