Window repair is a routine home maintenance project influenced by factors such as location, size, quality, and frequency. Establishing a realistic budget and engaging a certified professional are critical for success. 

The national average repair cost is $405, with most projects ranging between $178 and $635—clear planning ensures both cost efficiency and lasting performance. Simple repairs may cost as little as $70 per window, but repairs for more extensive damage can reach as high as $1,700. Labor costs for window repair usually run from $30 to $90 per hour, depending on the type of repair.

Standard window repair projects typically involve restoring the sash, seal, tracks, and operating mechanisms. In cases where damage extends to the frame or requires full glass replacement, costs will increase accordingly. The final project price depends on the specific components affected, the extent of the damage, and your window type.

Type of Repair

You might experience various issues with your window. Let’s explore some of the most common window repair jobs and how much each one costs.

Window Leak

Repairing a leaking window typically costs $100 to $600, depending on the underlying cause and the leak’s location. Resealing generally costs around $150, while professional caulking services typically cost about $50. DIY approaches may incur only material costs.

Window Thermal Seal

The cost of repairing a window’s thermal seal ranges from $75 to $200. Unlike standard resealing for leaks, thermal seal repairs specifically prevent the ingress of moisture and inert gases.

Window Balance

As a DIY project, parts and equipment for a window balance repair typically cost around $50, whereas professional services generally charge approximately $100.

Sash Cord

Repairing a window sash cord typically costs around $35 on a DIY basis, with material expenses ranging from $10 to $60. In contrast, professional repairs generally cost about $110, including materials and labor.

Flashing

Window flashing repair usually costs about $400, including materials and labor. Note that flashing repairs frequently involve addressing leaking skylights, which may incur additional expenses for interior water damage remediation.

Window Frame

Repair costs typically range from $75 to $200 for minor frame damage. In cases where the frame is rotted, expenses generally increase to between $250 and $800. These costs can vary considerably based on the window type and the extent of the damage.

Foggy Window

Repairing foggy windows typically costs between $75 and $200.

Cracked and Broken Glass

Repairing or replacing cracked or broken glass typically ranges from $75 to over $2,000, depending on factors such as window type and size. In some scenarios, the repair costs may exceed that of a replacement—where a basic window glass replacement generally costs around $280—making replacement a more viable option, except in cases involving historic or premium-quality glass.

Cost to Repair a Window by Number of Panes

A single-pane window repair costs between $75 and $200. This might include skylights, casement windows, fixed or picture windows, or hopper windows. Fixing one dual-pane window runs from $200 to $400 and might consist of single-hung, double-hung, or storm windows.

To repair windows with three or more panes, budget between $600 and $1,100 or even more for many-paned windows in hard-to-reach areas and extensive damage. Typical three-pane windows include bay windows and arched windows.

Window Repair Costs by Window Type

The type of window you have significantly influences repair costs. The table below outlines typical cost ranges for common window types. Additional factors—such as frame material and damage severity—further affect these estimates.

Other Window Repair Cost Factors

Several other factors, in addition to the type of window, the number of panes, and the specific repair work required, can influence the final cost of window repair.

• Material: Window repair costs can vary significantly depending on the material. A wooden window may cost as little as $100 to repair, while a fiberglass window can surpass $600. In general, wood, aluminum, and vinyl windows are less costly to fix than fiberglass and composite windows. require more materials and time for repair, which increases the overall project price.

• Extent of damage: The prices included in this window repair cost guide reflect average repairs. Expect much higher costs if your window has sustained excessive damage, such as a rotten frame or damaged windowsill. If the damage is too extensive, you may need to budget for window replacement costs, which can be more cost-effective than ongoing repairs. 

• Emergency repairs: If you need an emergency repair, expect to pay the repairperson or glazier double or triple this hourly rate. 

• Window accessibility: If the window is difficult to access, especially on higher floors, expect the hourly repair rate to be higher.

• Multiple windows: Some contractors may offer a discount if you need to fix several windows simultaneously.

DIY Window Repair vs. Hire a Pro

DIY window repair may be appropriate if the damage is minor and you possess the necessary skill set. This approach can eliminate labor expenses, though it requires a significant time investment for both material acquisition and execution. However, engaging a professional window repair contractor is the most reliable option when facing substantial damage, time constraints, or limited repair experience. Given that windows are a vital element of your home’s exterior, ensuring their optimal condition is essential.
