If window glass is broken, cracked, or chipped, its time to replace it. Window glass replacement cost depends on the type of glass, size, features, tint, and manufacturer. If the windows are older but the frame is in good shape, replacing the old glass with updated window glass can lower energy costs, increase the value of the home, add UV protection, and reduce noise pollution. According to HomeAdvisor, window glass replacement cost ranges from $180 to $406, with many homeowners spending approximately $276. Depending on the type of window, some glass replacements can cost as little as $100 or as much as $700. Many window professionals charge between $50 and $75 per hour to replace window glass, although the labor cost to install windows can increase if repairs need to be made or the glass replacement is complicated, with multiple glass panes. The cost to replace windows ultimately depends on the type and size of the window, the type of glass, the number of panes, the location of the window, and any special coating. The more customized the window and the glass, the more the cost of replacing windows will increase.

To find accurate window glass replacement costs, homeowners are advised to search online for reputable window replacement companies in their area. Local companies may have a window replacement cost estimator that will offer a rough calculation of pricing, and they can supply precise window replacement quotes when a homeowner decides on window glass replacement. Even homeowners who pay for window cleaning and other maintenance may discover chipped, cracked, or broken window glass in their home. This guide will cover some important factors that affect window glass replacement cost, additional costs and considerations, types of window glass, red flags that signal its time to replace a window, and some frequently asked questions regarding glass window prices.

How much does it cost to replace windows in a home? That depends on several factors. Window installation cost can vary from the national average of $276 due to glass type, window type, window size, manufacturer brand, and local labor prices.

The average cost to replace windows can fluctuate due to the specific type of glass used in the window. Some types of glass can range from $10 to $100 per square foot, but window glass replacement prices typically run from $3 to $12 per square foot on average, with double-pane glass ranging from $6 to $12 per square foot. Some of the most common types of glass are single pane, double pane, triple pane, low-e (low-emissivity), gas-filled, laminated, tempered, and frosted. Each of these glass types is discussed below.

There are typically various types of windows throughout a home, and the style chosen will affect the overall price of window glass replacement. While beneficial double-pane windows are common in most houses, the cost of replacing double-pane windows is considerably more than for single-pane windows. Depending on the type of window, a window professional may need to dismantle the window frame to replace the glass, which will result in higher labor costs. Below are some of the most common window types and their average window glass replacement cost.

Window size is an important factor in determining window glass replacement cost. To measure the window size, homeowners can multiply the width by the height. Typically, the bigger the window, the more expensive it will be to replace the glass. Another important factor when calculating glass replacement cost is the thickness of the glass. Windowpanes can range from inch thick to a full inch thick. If a homeowner wants to change the thickness of the glass pane, the frame will need to be replaced, since specific glass thicknesses require certain frames. Replacing a window frame can run from $200 to $600 depending on the type of window.

Window glass replacement cost will vary by window brand. Homeowners will need to keep in mind that some manufacturers require that the sash is replaced at the same time as the glass to keep the warranty valid. Additionally, replacing the glass without also replacing the window sash can cause leaks at the glazing point, regardless of the brand chosen. Below are common window brands and the average price to replace double-pane glass.

Most window professionals or glaziers charge approximately $50 to $75 per hour for window glass replacement. It takes about 45 to 60 minutes to replace a pane of glass, so if the window glass replacement project involves multiple panes or complex fittings, the cost of labor can increase significantly. The process involves removing the old glass pane, installing the new one, and sealing the glass in the frame.

When homeowners are budgeting to replace glass in a window, its helpful to have all the information regarding any additional costs and considerations that will affect the price of the project. These can include the cost differences between glass replacement and glass repair, glass replacement versus a whole window replacement, door window glass replacement, window reglazing, and any additional customizations.

Including labor, the cost to replace window glass can run from $300 to $880, while the cost to repair the glass pane can cost between $100 to $500. If the glass has a crack smaller than an inch, it can be repaired by mixing a resin and a hardener and applying it to the crack. The excess resin should be removed, and the glass pane should cure for 24 hours before it is cleaned. If the crack is larger than an inch, its recommended that the entire pane be replaced.

A glass pane can be replaced if the frame is in good shape but the glass is cracked or broken. Some manufacturers warranty the replacement only if the sash is replaced at the same time. If the window frame is old and would benefit from being replaced, the extra expense is generally worth it due to the increased energy efficiency and utility bill savings. The cost of new windows for a house averages $750 per window.

The style and size of a door window are the factors that affect door window glass replacement cost. Replacing window glass panes in a door can cost as little as $100 for a front door and as much as $5,500 for a sliding glass door, with the price fluctuating due to the frame structure, type of glass, complexity of the replacement, and door usage. Some homeowners decide to replace the entire door instead of just the glass, since the prices can sometimes be comparable. Below are the average costs for several common door window glass replacement types.

Window reglazing costs from $250 to $500 per window for labor and materials. The process involves removing the old putty around the windowpane and applying new putty for an airtight seal around the glass. If the frame and window are in good condition and the putty is deteriorating, reglazing is an energy-efficient and lower-cost option compared to putting in new windows. Window reglazing can improve the strength and insulation of a window.

Any additional add-ons to the window glass replacement costs such as window frame replacement, window tinting, window seal replacement, or window films will increase the cost of the project. Below are the costs of some of the most common customizations and add-ons that homeowners may want during window glass replacement.

Window glass replacement typically costs from $3 to $12 per square foot, depending on glass type. If specialty glass needs to be custom ordered, the pricing can increase significantly. Double- and triple-pane glass is typically more expensive due to the gases between the windowpanes. Below are some of the most common types of window glass and the cost to replace them.

Single-pane window glass replacement can cost from $150 to $400. Single-pane windows dont provide as much insulation against temperature fluctuations or noise pollution and are commonly found in older homes.

Double-pane window glass replacement ranges from $150 to $600, depending on window type, size, frame material, and glass thickness. With their double layer of glazing, double-pane windows are the standard style in many homes. These windows increase energy efficiency by reducing thermal loss.

Triple-pane window glass replacement runs from $400 to $950, depending on glass quality and brand. Also known as thermopane, triple-pane glass is the most energy efficient, with three layers of glazing. Homeowners who live in extreme climates will often choose triple-pane glass for increased insulation against the elements.

Low-emissivity glass costs between $350 and $840 for replacement. The layer of metallic oxide coating reduces UV rays passing through the window by 99 percent and can diminish energy loss by 30 percent to 50 percent.

Argon gas is typically used in windows that have more than a -inch distance between glass panes. For double- or triple-pane windows that are filled with argon gas, glass replacement can cost from $375 to $850.

Krypton gas is used in double- or triple-pane windows that have a space of less than inch between panes. Replacing krypton gas-filled glass panes ranges from $525 and $1,190. Since krypton gas is denser than argon gas, it insulates better and provides increased energy efficiency.

The cost to replace laminated glass is $275 to $625. Produced by bonding layers of glass with resin, laminated glass is about five times stronger than standard glass. It can reduce noise pollution and withstand breakage from a thrown toy, rock, or wind-blown projectile.

Tempered glass replacement runs from $180 to $700, depending on window type and size. This type of glass is a safety glass that shatters into rounded pieces to reduce the chance of injury. Tempered glass is four times stronger than untreated glass and is used to comply with specific safety standards or building codes.

Frosted glass is commonly used to let light in but prevent passersby from looking into a home. The cost to replace frosted window glass panes is $350 to $800.

If the window frame is in good shape but the glass is damaged, its a good candidate for window glass replacement. When homeowners notice a cracked or chipped windowpane, moisture or condensation between the glass panes, increased energy bills, or cold window glass during the winter months, or if they have regulations they need to follow regarding historic windows, window glass replacement may be the best option.

If a windowpane is cracked, the only way to fix it is to replace the glass. Replacing the window glass can prevent breakage and injury while continuing to keep the window energy efficient.

If theres condensation between a double- or triple-pane window, that means the seal is broken. Moisture is getting between the windowpanes, and it can freeze or frost over in cold weather. This can cause outside air to get inside and drive up the cost of the heating and cooling bill. To ensure energy efficiency and have a tight seal around the windowpanes, a window glass replacement is necessary.

Are your windows no longer efficient?

Replacing old, leaky windows with energy-efficient window glass that has a tight seal can lower energy bills by 10 percent to 30 percent. New window glass can prevent thermal heat transfer and air leaks and keep a home comfortable year-round.

If double- or triple-pane windows are cold to the touch, that means the layer of gas between the windowpanes has escaped and the glass is no longer insulated. Replacing the panes and the gas will ensure proper insulation and a consistent temperature inside the home.

Historic homes have specific guidelines when it comes to windows. To preserve the original look of the building, the windows need to match the historical architecture. If the window frame is still in good condition but the glass is cracked or broken, window glass replacement is the best option, since replacing windows in an old house can be an expensive project that is complicated by historic preservation ordinances.

For a DIY replacement project, homeowners with window glass replacement experience can expect to pay between $100 and $630 for the windowpane and another $100 to $200 for supplies. Supplies can include glazing tools, glazing removal tools, pliers, heat gun, gloves, and glass cutting tools. However, the average homeowner likely wont have the skills and tools necessary to complete this as a DIY project.

Since window glass replacement can be tricky, many homeowners opt to hire a professional glazier for the job. A professional has the experience to install the new window glass correctly, making sure the new window is sealed and properly placed. Depending on the window glass manufacturer, the warranty may be valid only if the glass is installed by a window professional, which makes it even more important to check the fine print and lean toward hiring a professional. To ensure the proper seal and fit, and to avoid cracks and chips, a window professional is usually the best option for a window glass replacement project.

The cost to replace window glass can quickly add up and strain a home improvement budget. One way to save is to use the cheapest window glass, but there are other ways to stay within a budget without compromising on quality.

Talking to a window glass professional and asking the right questions can help minimize miscommunication and get the best results. The following are some questions to ask before starting the project.

Before deciding on window glass replacement, homeowners will want to have all the information they need regarding the cost. Below are several frequently asked questions for homeowners to consider before starting the project.

To have a proper airtight seal, replacing both panes in a double-pane window is recommended. Both glass panes should be replaced at the same time to ensure effective insulation and a tight seal.

Its possible to fix a crack in a window without replacing it, but its considered a temporary fix before the glass pane will need to be replaced. There are glass repair kits that even beginner DIY-ers can use successfully. The glass needs to be cleaned before the epoxy hardener and resin that come with the repair kit are mixed together. The mixture will need to be applied to the crack and left to dry thoroughly. A sharp blade will remove any excess mixture, and the glass can be cleaned and polished with a microfiber cloth.

An insulated gas unit, or IGU, is two panes of glass with argon or krypton gas in between with an airtight seal. The gas acts as an insulator and reduces the amount of heat transfer.

If the window frame is in good condition and the glass is chipped, cracked, or broken, the windowpane can be replaced. If there are issues with the entire window, a full window replacement may be the best option.

A double glazing unit (DGU) is the same as an insulated gas unit (IGU). Both types utilize multiple panes of glass with gas in between for increased insulation.

Its more budget-friendly to replace the glass instead of the entire window.
