Average Cost of Replacement Window Glass by Type

Tempered Glass

• $12-$14 per square foot

• One of the hardest and strongest types of glass

• Less likely to cut someone if it breaks

• Cannot be cut without shattering

• More expensive than annealed glass

Laminated or Insulated Glass

• $10-$20 per square foot

• Holds up well under impact

• Blocks 99% of UV-light transmission

• Has sound-reduction properties

• The noise-reduction properties of laminated glass come from a specific amount of air space between the two panels, making it more difficult to install.

Thermopane or Thermal

• $10-$14 per square foot

• More energy-efficient than standard single-pane windows

• Reduces heating and cooling costs

• Moisture can build up between the glass panes, requiring the panes to be replaced.

Plate or Flat

• $25-$100 per square foot

• Flat, clear, and contains few irregularities

• Not as good of an insulator as other window glass options

• Can be easily scratched

Double-Glazed

• $3-$6 per square foot

• Reduces noise and heat transmission through the window

• Helps reduce energy bills

• Cannot be easily repaired, as disturbing the glass can break the airtight seal

• Higher initial cost

Shaw

• $10-$14 per square foot

• Energy-efficient with several weather-proofing features

• Easy to clean

• Made of 1+ movable panes

• Not as secure as other window types, making it easier for an intruder to enter

Window Replacement Cost Factors

How much you pay for window glass depends on a number of factors. You’ll pay more for custom glass, high-end upgrades, and inaccessible window replacements like a skylight than you would to replace a single standard plane. The more skill and abor the project requires, the more it’s going to cost.

Size

Size is a significant factor when determining the cost of replacement window glass. The bigger the window, the more you’re going to pay—but it’s not just about height and width. Glass thickness is also a factor. Most window panes are anywhere from 1/8 of an inch thick to 1-inch thick. If you change the thickness when you replace the pane, you may have to also replace the frame, which usually costs anywhere from $200 to $600

Window Type

There are all different types of windows, and the style can affect the overall cost of a window replacement. Though double-paned glasses come with many benefits, they will cost more to replace than a single-paned window—especially if the window is filled with argon or krypton gas. Depending on the type of a window, a contractor may have to remove part of the trim to replace the glass, which can also drive up costs. Here’s what you can expect to pay for a replacement.

Custom Glass

Custom glass is substantially more expensive than a standard pane in a standard size. For example, the cost of a stained glass window could be anywhere between $100 and $10,000 depending on the level of detail and artistry.

Glass Upgrades

Glass Door Replacement Cost Factors

Glass doors aren’t all that different from regular windows when it comes to replacing a glass pane. Size and style are two of the biggest factors. Again, the more labor and materials a project takes, the more it’s going to cost.

Door Type

Replacing the glass panes on a door ranges from as little as $100 for a front door to more than $5,500 for a sliding glass door. The cost varies based on the usage, type of glass, and actual structure of the frame, but here are some typical costs.

Size

Smaller glass panes cost less than larger glass panes. If you’re replacing a couple of panes in a small window on a front door, you’ll pay less than you would to replace large glass panes on bi-fold patio doors.

Window Replacement DIY vs Pro

If you’re replacing a window pane on your own, you can expect to spend between $100 to $630 on the glass itself, plus another $100 to $200 on supplies. Since glass is fragile and replacing a pane is complicated, most homeowners hire a local window glass replacement professional unless they specifically have contracting experience. 

Labor Costs

Most contractors charge between $50 and $75 per hour to replace window glass. This can add up if the glass replacement is complicated or you’re replacing multiple panes along with making other repairs. The upside is that contractors have the skills and experience necessary to install the glass properly, can generally do the job quickly, and will often provide a warranty.

FAQs

When should I repair or replace a window?

Old, single-pane windows can usually be repaired, but modern windows may require a total replacement depending on the problem. If you’re dealing with broken glass, you’ll likely need to replace the pane. In some cases, you may also want to replace the window sash or repair the muntins and mullions that hold the glass. 

Can I replace just the glass of a window?

Yes, you can replace a broken pane. If you have frequent problems with your windows, you may want to consider a replacement.

How long does a window replacement take?

A skilled contractor can usually replace a window in 30 to 45 minutes, but it can take up to 90 minutes to replace wood, aluminum, or steel windows. The labor depends on the size and type of window. If you want to replace numerous, large custom windows, it can take one or two days.
