If you have window issues or windows older than 10 years, it might be time to consider replacing the glass. Window glass replacement can greatly benefit homeowners, such as lowering energy costs, reducing outside noise, UV protection, easy maintenance, enhancing curb appeal, and increasing home value.

The cost to replace a glass window depends on the size, window type, tint, and features. The national average ranges from $300 to $880, including labor, with most homeowners spending about $375 per window to replace clear glass on one standard-size 30” by 36” sliding double-paned window. If you just want to replace clear glass in a standard single-hung, single-pane window, expect to pay around $200. Replacing all the triple-pane glass in a bow window costs around $2,100.

Window Glass Replacement Cost by Size

One factor in window glass replacement cost is the glass’ size. Size is measured by calculating the width times height. Thickness is also a factor and usually ranges from ⅛ of an inch to 1 inch. If the frame is still intact, you can save money by replacing the glass with the same thickness as you had before because different thicknesses of glass require different frames. The prices in the chart below are based on double-pane glass with each pane being ½-inch thick:

Window Glass Replacement Price by Window Type

There are many window types to choose from. Each type has a different number of window panes. This affects the project’s steps and cost, depending on the window type. Below are some of the most common types of windows and an average cost for replacement glass:


Window Glass Replacement Price by Window Type

Window Glass Replacement Price by Window Type


Window TypeAverage Cost (Material Only)
Skylight$50 - $800
Storm$100 - $400
Egress$100 - $800
Casement$150 - $850
Sash$150 - $950
Picture$200 - $435
Bay$320 - $3,800 (all panes)
Storefront$500 - $3,000
Bow$690 - $1,800 (all panes)


Skylight Glass Replacement Cost

Replacing the glass for a skylight window costs between $50 and $800, depending on the size and if you use single, double, or triple-pane glass. A skylight window is located on the roof for light and ventilation. They can be opened with a pole or crank or with an electric motor or pneumatic device. Skylights range from small windows that only let in a little light to bigger windows that provide enough natural light to illuminate a large room.

Storm Window Glass Replacement Cost

The average price for replacing the glass in a storm window 1 ranges from $100 to $400. Storm windows are installed on the outside with the primary windows for extra insulation. They are often used with single-pane windows and are more efficient than replacing the windows with double-pane glass. Many storm windows have superior air sealing and eliminate noise and condensation. These features affect the price.

Egress Window Replacement Cost

The average price range for egress window glass replacement is $100 to $800. Egress windows are designed to provide an emergency exit from a building. Building codes often require them in bedrooms and basements. They can be of various types, such as double-hung, single-hung, or casement windows, and they must be able to fit a human.

Casement Window Glass Replacement Cost

The average cost to replace a pane in a casement window 2 is usually $150 to $850. Casement windows are attached with hinges and open like a door. There are different types of casement windows, and each type usually has one to three panes.

Sash Window Glass Replacement Cost

Replacing the glass in sash windows 3 typically costs between $150 and $950. Sash windows open by sliding and can be single or double-hung. Most often, they slide vertically, but occasionally, they slide horizontally.

Picture Window Glass Replacement

A picture window 4 is a large fixed pane window, usually with clear glass, designed to give you a “picture” view of the outside. Because of their size, picture window glass panes may be slightly more expensive to replace than other window glass types. Typical prices for replacement glass for a picture window range from $200 to $435.

Bay Window Glass Replacement Cost

The average cost to replace all three panels of a bay window 5 is $320 to $3,800. A bay window projects outward, usually at an angle. It has three panels, typically a fixed picture window and one narrower window on each side. Sometimes, the smaller windows open to vent.

Storefront Glass Replacement Cost

The average range to replace storefront glass ranges from $500 to $3,000, depending on the size and type. Storefront windows are large fixed-pane display windows. Plate glass for storefront windows runs about $5 a square foot, but tempered glass costs approximately $25 a square foot.

Bow Window Glass Replacement

A bow window is similar to a bay window in that it projects outward. However, bow windows have four, five, or six panels and are generally more rounded than bay windows. You can also replace the glass in one panel, but the average cost to replace the glass in all panels is around $690 to $1,800.

Broken Window Pane Replacement Cost

The cost to replace a broken window pane varies based on the thickness and glass type. If one pane of a double or triple-pane window breaks, replace the entire piece instead of fixing the damaged pane. Here are the average costs to replace one to three panes.


Broken Window Pane Replacement Cost

Broken Window Pane Replacement Cost


Glass TypeAverage Costs (Material Only)
Single-Pane$150 - $400
Double-Pane$150 - $600
Triple-Pane$400 - $950


Single-Pane Glass Window Replacement

A single-pane window is the most basic of window glass designs and only has one glazing or glass layer. Because there is only one pane, they offer the least insulation and noise reduction. Due to this, single-pane windows are not as common and are found mostly in older homes. Single-pane glass costs about $150 to $400.

Double-Pane Window Glass Replacement Cost

Double-pane, or insulated glass, windows typically cost around $150 to $600 to replace. Double-pane windows have two layers of glass or glazing. They have become the standard in window glass. This specific design is popular because there is an air pocket between the two panes for insulation. Double-pane windows also increase energy efficiency significantly. They are a cost-effective way to decrease thermal loss while remaining budget-friendly.

Triple-Pane Replacement Windows

Triple-pane glass, also called thermopane glass, has three glass or glazing layers and is the most energy-efficient design. This also means it is the most expensive option for windows. If the efficiency of your windows is a top priority, triple-pane is the best choice. The average cost for a triple thermopane window glass replacement is around $400 to $950.

Window Glass Cost by Glass Type

Many window glass types must be considered in window glass replacement, including safety glasses like laminated and tempered and coatings. Dual-pane and triple-pane glass also include gases between the windows, which impact the final price.


Window Glass Cost by Glass Type

Window Glass Cost by Glass Type


Glass TypeAverage Costs (Material Only)
Tempered$180 - $700
Laminated$275 - $625
Frosted$350 - $800
Low-E Coating$350 - $840
Argon Gas$375 - $850
Krypton Gas$525 - $1,190


Tempered Glass Window Replacement

Tempered glass is a safety glass made by strengthening standard glass through a process involving heat, pressure, and chemicals. It can shatter but is less likely to break than laminated or standard glass. Tempered glass window prices average from $180 to $700, depending on the size and type. Special effects like polarized glass can raise the price to over $1,000.

Laminated Glass Replacement Windows

Laminated glass helps prevent forced entry and is produced by bonding one or two layers of glass with resin. It is about five times stronger than standard glass and can survive a rock or bullet. It also reduces noise. Laminated glass tends to cost about $125 to $150 more than the same-size glass without lamination. The average cost to replace laminated glass in a window is $275 to $625.

Frosted Glass Price

The average cost to replace frosted window glass ranges from $350 to $800. Frosted glass is used for decoration and privacy. This glass uses sandblasting or acid etching to make it more opaque. It is commonly used because it prevents outsiders from looking in but can still let light through.

Low-E Window Glass Replacement

A low-E coating can be applied to window glass to restrict sunlight and UV rays from entering. Low-E stands for low emissivity, which means it decreases the amount of energy the glass radiates. The layer is metallic oxide that can reduce energy loss significantly, sometimes even by 30% to 50%. The average cost for a low-E coating is between $350 and $840.

Argon Glass Replacement

Argon gas is often located between panes in a double or triple-paned window. Argon is typically used in windows with more than a ¼ inch of space between window panes. This gas is less expensive than krypton, which is another popular option for window gas. Argon provides good insulation in wider windows, but it is not effective in windows under a ¼ inch. Argon gas windows typically cost about $375 to $850.

Krypton-Filled Windows

Krypton gas is more expensive than argon, but it provides better insulation because it is denser. This makes it more energy-efficient and is recommended when the space between panes is small, less than a ¼ of an inch. Even in windows with such a small volume of space between panes, krypton gas can provide thermal insulation. The cost of a krypton gas-filled window averages between $525 and $1,190.

Replacement Window Glass Cost by Brand

The cost of replacement glass varies by brand, and many brands offer products across a wide price range. For some brands, installing replacement glass without installing a new sash is not recommended and may void the warranty. The average costs listed are for double-pane glass.


Replacement Window Glass Cost by Brand

Replacement Window Glass Cost by Brand


Brand of WindowAverage Cost (Material Only)
Pella$200 - $290
Jeld-Wen$220 - $330
Harvey$250 - $300
Simonton$250 - $400
Alside$250 - $500
Milgard$300 - $600
Andersen$400 - $600

Pella is a well-known manufacturer that makes windows across many price points. They are known for allowing customers to personalize their window choices beyond the standard. Expect to pay $200 to $290.

Jeld-Wen Window Glass Replacement

Jeld-Wen is a large producer of windows and replacement window glass. They are known for their energy-efficient options and innovations in glass protection. Their prices tend to be lower than many of their competitors, but they are mostly a new construction company, so you may have to replace the entire window rather than finding replacement glass. The average price is $220 to $330.

Harvey Window Glass Replacement

Although the company makes windows out of various materials, they are best known for vinyl windows. They are a solid mid-range option but without a lot of frills. Average costs are $250 to $300.

Simonton Window Glass Replacement

Simonton is known for its vinyl windows. They have many year-round thermal window options and are nationally available. They are sturdy and reliable, and the company stands behind their product. However, they do not offer a particularly wide range of glass. Replacement glass without the window is difficult to locate. The average price is $250 to $400.

Alside Window Replacement

Alside is a large building supply company specializing in vinyl windows known for energy efficiency. The average price to replace an Alside window is usually $250 to $500.

Milgard Window Glass Replacement

However, they are sold only through authorized dealers, which are not located in every city. The prices range widely depending on the type of window and series. Expect to pay $300 to $600.

Andersen Window Glass Replacement

Andersen windows are popular, dependable, and sold in national stores like Lowe’s and Home Depot. They are known for top-quality materials and excellent warranties on replacement windows. However, replacing only the window glass without replacing the sash in Andersen windows can sometimes leak at the glazing point, and the company only warranties replacing both the sash and glass. The average price is $400 to $600, although replacement for bay windows runs significantly higher.

Window Glass Replacement Cost

Labor costs add about $50 to $125. For example, the average cost for replacing clear glass on one standard-size 30” by 36” sliding double-paned window, including labor costs, is around $375.The replacement requires removing the existing pane, installing a new one, and sealing it in place. This cost includes removal and window fitting. It takes approximately 45 to 60 minutes to install each pane. A person who replaces window glass is often referred to as a glazier or glass technician.

The process of window glass replacement starts with the removal of the old glass. Once the glass is removed, the technician cleans the area to remove debris or old putty. The new glass can then be put into the frame, and putty is applied around the edges to keep it in place. The putty is left to dry and can be painted or covered once dry.

Window Door Glass Replacement Cost by Door Type

Similar to window glass replacement, door glass replacement is another project that may need to be completed to keep your doors working efficiently. Glass replacement for doors depends on the door’s size, glass, and window type. Sometimes, it may be better to replace the entire door rather than the glass because it is usually similar in price.


Window Door Glass Replacement Cost by Door Type

Window Door Glass Replacement Cost by Door Type


Door TypeAverage Cost (Material Only)
Back$100 - $300
Shower$120 - $200
Storm$125 - $290
Front $150 - $600
French$200 - $400 per pane
Sliding$200 - $600 per panel
Patio $200 - $1,200


Back Door Glass Replacement Cost

The average cost to replace back door glass ranges from $100 to $300. Back doors help keep the elements out of your home. They can be damaged by wind-blown or thrown objects, or the glass can become foggy from moisture. They are typically less decorative than front doors, and buying a new door is often the same price as replacing the glass.

Shower Door Glass Replacement Cost

The average replacement cost for shower door glass is between $120 and $200. Shower doors separate the shower area and prevent water splashing. They commonly use fogged glass for privacy. Because of this, the cost to replace shower door glass may be slightly higher than replacing other glass types. The door’s size also impacts the price.

Storm Door Glass Replacement Cost

Costs to replace the glass in storm doors range from $125 to $290. Storm doors are exterior doors on the primary door for additional insulation. Wind-blown and thrown objects can break this glass, and moisture can creep into it and fog or chip the glass. Often, replacing the entire door is the same price as replacing the glass.

Front Door Glass Replacement Cost

Typical costs to replace the glass in a front door usually run from $150 to $600.The front door is the entrance to your home. Environmental factors can chip this glass or cause it to become foggy. Balls and other objects also can damage the glass.

French Door Glass Replacement Cost

The average cost to replace French door glass ranges from $200 to $400 per pane. A French door is a door on hinges with glass for the full length, and they usually come in pairs. They are typically used as an entrance to a balcony or patio but can be used in other spots. Heavy wind-blown articles and other severe weather can break the glass. The glass can also become murky and require replacement.

Sliding Glass Door Glass Replacement Cost

The cost to replace the glass in sliding glass doors is usually $200 to $600 per panel. Sliding glass doors often are used at the entrance to a patio or deck. The glass to these doors can be broken by balls and wind-blown objects, and it can become foggy, broken, or chipped from environmental factors.

Energy-Efficient Window Glass Replacement

When replacing window glass, you may want to consider the costs and benefits of upgrading to energy-efficient windows. The EPA estimates that replacing all single-pane windows with double-pane can save the average family $125 to $340 a year, but double-pane windows cost an extra $100 per pane. The federal government and some states offer tax credits for installing energy-efficient windows, which might help you recoup the cost faster.

Emergency Window Glass Repair

Expect to pay between $120 to $150 per hour for emergency window glass replacement services. Glass replacement companies understand the importance of having functional windows. There are specialists to call who work 24 hours a day, providing emergency glass repair and replacement in the case of a break-in or emergency. Emergency repair technicians typically come out immediately to repair the problem at an additional cost.

Despite the cost, consider replacing a cracked window as soon as possible. For example, a cracked window results in air leaks, meaning your heating and cooling systems must run overtime. It also allows for more sunlight, which can fade furniture and leave your home at risk for break-ins. If the weather is extremely hot or cold, a cracked window becomes more prone to shattering.

Window Reglaze Cost

Reglazing costs between $250 and $500 per window for materials and labor. The glaze is the putty between the window’s panes and frame for an air-tight, water-tight seal. Over time, the glaze can deteriorate. Reglazing is putting new putty over deteriorated spots to seal the window. It can improve your window’s energy efficiency and may be an option rather than replacing the window if the only issue is deteriorated putty. It is also an eco-friendly option. If the window has other issues, such as a rotting wood frame, poor casing, broken glass, or inoperable sash, the window or glass should be replaced.

Replace vs Repair Window Glass

Sometimes, the pane only has a small crack, such as a pebble tossed from a lawnmower. You may be able to fix this crack rather than replace the entire pane if you do so immediately. You or a professional must first wash and dry the window and apply a mix of resin and hardener with a putty knife. The excess resin is then removed, and the repaired glass needs to cure for 24 hours before the pane is cleaned with window cleaner. However, repairing is typically not a good option if the crack is larger than an inch. Cracks also tend to worsen over time.

Replacing Glass vs Replacing Whole Window

The cost to repair the window frame varies, depending on the material and how much hardware must be replaced. The average cost to repair a window frame runs from $170 to $600. If the glass needs replacement, the materials cost averages $375. Replacing an entire window usually costs between $650 to $1,500.

If someone has thrown a baseball through your window, replacing the glass can be less expensive than the entire window. Keeping your window frame means it still matches the others in your home, which is more aesthetically pleasing than mismatched windows. However, replacing the whole window may be a better long-term solution for energy savings, particularly if the frame is old or of poor quality material. Some manufacturers do not honor warranties if the glass is replaced without replacing the sash. Finally, the window is usually not worth saving if the seal is broken, the dividers or muntins are broken, the windows need replacement in 3-5 years, or you have low-quality windows.

Enhancement and Improvement Costs

Window Frame Replacement Cost

If your wooden window frame breaks, expect to pay between $175 and $300 in repairs, including labor. For window frames made of vinyl or fiberglass, repair costs range from $300 to $600. For broken aluminum window frames, expect to pay $250 to $500, including labor costs. Window frames play an important role in the structural support of your windows, while reducing heating and cooling costs. It is very important to keep them free of cracks and gaps to perform well.

House Window Tinting Prices

Glass tinting costs roughly $7 per sq.ft. Window glass tinting can be a very smart investment for homeowners. Window tinting provides several benefits, such as reducing your energy bills, lowering window glare, and improving your home’s safety and privacy. It even reduces UV exposure.

Window Seal Replacement Cost

The average cost to replace a window seal is $70 to $120. Double and triple-pane windows contain a seal around the perimeter to make them airtight. When seals fail, condensation, dirt, and grime can build up. Once the seal fails, the outside elements can come into your home more easily. To repair a failed seal, you or a professional need to remove the pane of glass to find the break, clean the inside of the panes, replace the gas and seals, and reinstall the windows.

Window UV Film

UV Film can be applied to window glass to reduce UV rays. While the film can be purchased separately from the window at nearly any hardware store, it is recommended to be applied by a professional for the best outcome. This film can be non-reflective or reflective and even different colors. There is some variation in the UV film that can be purchased, and it can be chosen to suit any home or building. It can block 99% of UV rays and cut solar heat by up to 82%. Due to the various styles, colors, and quality, the cost of UV film ranges from $5 to $12 per square foot.

Spectrally Selective Window Film

Spectrally selective coatings are a unique style of low-E coating that allows in more light than a standard low-E coating. Low-E coatings themselves are very energy-efficient but decrease visibility. A spectrally selective coating allows for energy efficiency while providing good visibility. A spectrally selective coating is not as energy*efficient as a normal low-E coating. These coatings usually cost between $8 and $16 per square foot.

Additional Considerations and Costs

  • Consider upgrading to energy-efficient windows. Choosing an energy-efficient option can be very beneficial. Energy-efficient windows reduce energy costs by more than 30%, helping lower your monthly energy bills. They are expensive but a great investment and save money in the long run.
  • Having strong and efficient windows is very important for any home. Experts recommend that windows are checked yearly for leaks, damage, cracks, and water-softened wood.
  • Although window glass replacement could be a DIY project, it is best to opt for professional installation for the best results. Replacing window glass may sound easy, but you may experience some issues with fitting the frame properly, mold and condensation, or building codes. Hiring a professional company for window glass replacement eliminates the headache of dealing with these issues and often offers a great warranty.
  • Most window companies offer a good warranty on the glass. Most warranties range between 10 and 20 years. This warranty usually does not include damage due to nature. Always ask about the warranty before you select the company.
  • Ask the company if they have discounts available. Many companies offer discounts if you decide to replace all the windows in your house instead of just a few. If you need door glass replacement, this may be the time to do so. In many cases, the more windows you replace, the better discount you receive.
  • Similar to window glass replacement, door glass replacement is another project that may need to be completed to keep your doors working efficiently. Glass replacement for doors ranges in price from $200 to $800, depending on the door’s size, glass, and window type. Sometimes, it may be better to replace the entire door rather than just the glass because it is usually similar in price.

FAQs

  • How much does it cost to replace glass in a window?

The average cost to replace glass in a window ranges from $300 to $880 per window. The cost depends on the window’s size, whether it is single-pane, double-pane, or triple-pane, the brand, and the window type.

  • Can you replace just the glass in a window?

Yes, you can replace just the glass in a window in many cases. The current window frame can be kept in place. In some cases, replacing the entire window makes sense. This is true if the window has only a few years remaining in its lifetime, the frame is rotting, or it needs more energy savings. Some warranties may be invalidated if only the window glass is replaced.

  • How much does it cost to replace the glass in a double-glazed window?

The average cost to replace the glass in a double-glazed window is from $150 to $600. This includes labor costs. The price varies based on the window’s size and possibly the brand.

  • Is it cheaper to replace glass or the entire window?

In most cases, replacing glass is cheaper than replacing the whole window. On the other hand, sometimes replacing the entire window is a better long-term option. For example, if the window is old or the frame is beginning to deteriorate, it may make sense to replace both at the same time to reduce costs.

  • Can foggy double-pane windows be repaired?

Sometimes, fog in double-pane windows results from seal failure and can be repaired by replacing the seal. Remove the pane, find the break in the seal, clean the window’s inside, replace the argon gas, replace the broken seal, and reinstall the window.

  • How long does it take to replace a window?

A professional can generally replace a window in 40 to 60 minutes if only the glass needs to be replaced and the new glass size is the same. More time may be required to replace the frame, especially if you want to change its size. This project can take between 2 and 4 hours.
