How Much Does Window Repair Cost? [2026 Guide]

National Average Window Repair Cost

Window repair projects can cost anywhere from under $100 for small fixes to $650 or more for complex repairs, with the average homeowner paying around $200 to $400 per window for professional service. Simple work like tightening components or restoring seals is typically inexpensive, while repairs involving broken glass, failed insulation, or damaged frames fall on the higher end of the price range.

What you ultimately pay depends on the window’s construction, materials, size, and location, as well as how long the problem has gone unaddressed. Catching issues early helps keep repairs affordable, but delaying service can allow moisture, air leaks, or structural damage to spread, often driving up costs well beyond the initial repair.

Most window repairs fall into the mid-range when addressing cracked glass, damaged seals, or balance issues. Costs rise when specialized glass, large windows, or structural repairs are required.

All pricing reflects 2026 national averages based on contractor estimates and homeowner reports.

Factors that Impact Window Repair Cost

Window Repair Cost by Issue

Most window repairs fall into a few common categories: glass damage, seal failure, air leaks, hardware issues, and operational problems. Draft and hardware repairs are typically the easiest and most affordable to fix, while glass and seal repairs tend to be more expensive because they often require replacing insulated panes or custom glass units.

Below, you will find average window repair price ranges based on the issue at hand.

Cracked or Broken Window Glass

Cracked or broken glass is usually easy to spot and can be caused by impact, temperature changes, or structural shifting. Even small cracks can spread quickly and compromise insulation and safety, so it is important not to delay the repair. Fixing cracked glass typically costs $150 to $400, while larger panes or insulated glass units can push costs higher.

Foggy Windows or Failed Seals

If you notice condensation or a foggy appearance between panes, the window’s seal has likely failed. This allows moisture inside the insulated glass unit and reduces energy efficiency. Seal failure almost always requires glass unit replacement rather than resealing, with typical repair costs ranging from $200 to $500.

Drafts and Air Leaks

Drafts around windows often indicate worn weatherstripping, failed caulking, or minor frame gaps. You may feel cold air near the window or notice higher energy bills. These repairs are among the most affordable, usually costing $75 to $200, especially when addressed before moisture damage develops.

Stuck, Jammed, or Hard-to-Open Windows

Windows that won’t open or close smoothly often have balance issues, track damage, or warped components. This problem can worsen over time and create safety or ventilation concerns. Repairs typically cost $100 to $250, depending on window type and the parts required.

Broken Locks, Latches, or Hardware

Loose, broken, or malfunctioning hardware can make windows difficult to secure and may affect alignment. Hardware repairs are usually straightforward and cost between $75 and $200, depending on the window style and availability of replacement parts.

Frame Damage or Rot

Frame damage—especially wood rot—can result from long-term moisture exposure and may not be immediately visible. Signs include soft spots, peeling paint, or visible decay. Minor frame repairs typically cost $200 to $400, while more extensive damage can increase costs and may indicate that replacement is the better option.

Window Repair Cost by Window Type

The cost to repair a window also depends on the window’s design and how it operates. For example, larger or more complex window styles—such as bay, bow, or skylight windows—cost more to repair due to size, weight, and accessibility.

Below, you will find average window repair price ranges based on the type of windows you have.

Single-Hung Windows

Single-hung windows commonly need repairs for broken locks, worn balances, or draft issues around the sash. Because only one sash moves, repairs are generally straightforward and affordable. Most single-hung window repairs cost between $100 and $350, depending on whether the issue involves hardware, glass, or sealing.

Double-Hung Windows

Double-hung windows can develop problems with balance systems, tilted sashes, or air leaks around both panels. You may notice difficulty opening or closing the window or uneven alignment. Repairs typically range from $150 to $400, especially when balance replacement or glass repairs are required.

Casement Windows

Casement windows often require repairs to hinges, crank mechanisms, or locking hardware. When these components fail, the window may not seal properly or may be difficult to operate. Casement window repairs usually cost $150 to $450, with costs increasing if hardware is specialized or the glass needs replacement.

Sliding Windows

Sliding windows commonly experience issues with worn tracks, rollers, or alignment problems that cause sticking or difficulty sliding. Dirt buildup and track damage are frequent causes. Repairs generally cost between $125 and $400, depending on whether parts need replacement or realignment.

Bay or Bow Windows

Bay and bow windows are larger, multi-panel units that can develop problems with seals, framing, or support components. Signs of trouble include drafts, foggy glass, or visible separation between panels. Because of their size and complexity, repairs often range from $300 to $650 or more.

Skylight Windows

Skylights are prone to leaks, seal failure, and condensation issues due to their roof placement. Water stains, dripping, or fogging are common indicators that repair is needed. Skylight repairs typically cost $250 to $600, especially when flashing or insulated glass units must be addressed.

Window Repair Cost by Frame Material

The material used for a window frame affects both how it wears over time and how expensive it is to repair. Some materials are more prone to rot or corrosion, while others are easier and less costly to fix.

Vinyl Window Frames

Vinyl frames commonly need repairs for cracked corners, failed seals, or warped sections caused by temperature changes. Signs include visible cracks, air leaks, or difficulty opening the window. Vinyl window frame repairs are usually straightforward and cost between $100 and $300.

Aluminum Window Frames

Aluminum frames can corrode over time, especially in humid or coastal environments. You may notice pitting, oxidation, or alignment issues that affect operation. Repairing aluminum window frames typically costs $150 to $400, depending on the extent of the corrosion and whether reinforcement is needed.

Wood Window Frames

Wood frames are prone to rot, swelling, and insect damage when exposed to moisture. Soft spots, peeling paint, or visible decay are common warning signs. Wood window frame repairs tend to be more expensive, ranging from $200 to $650, especially when sections must be rebuilt or refinished.

Fiberglass Window Frames

Fiberglass frames are durable but can crack or separate at joints over time. Damage is often less visible but may cause air leaks or difficulty operating the window. Repairs typically cost $150 to $500, depending on the severity and accessibility of the damage.

Composite Window Frames

Composite frames combine multiple materials and may experience issues like delamination or joint separation. These problems can lead to drafts or moisture intrusion. Composite frame repairs usually range from $175 to $450, with costs varying based on the manufacturer and frame construction.

Window Repair Cost by Size

Window size plays a significant role in repair costs, as larger windows require more materials, longer labor time, and heavier glass. Smaller windows are generally quicker and less expensive to fix, while large or custom-sized windows tend to cost more.

Small Windows

Small windows, such as bathroom, basement, or utility windows, most commonly need repairs for cracked glass, seal issues, or minor frame damage. Because these windows use less material and are easier to access, repairs are typically affordable. Most small window repairs cost between $75 and $200.

Medium-Sized Windows

Medium-sized windows, including standard bedroom or kitchen windows, may experience issues with glass breakage, worn balances, or air leaks. Repairs often require more labor and materials than small windows, especially for insulated glass units. Costs typically range from $150 to $400.

Large Windows

Large windows, such as picture windows or oversized living room windows, are more expensive to repair due to their size, weight, and installation complexity. Glass replacement and seal failures are common issues. Repair costs generally fall between $300 and $650+, particularly when custom glass is needed.

Window Repair Labor Costs

Most window repair professionals charge $50 to $100 per hour, with many jobs billed as flat-rate services. Labor typically accounts for a large portion of the total repair price, especially when glass replacement or complex adjustments are required.

Additional Window Repair Costs to Consider

Some window repair situations involve added complexity, specialized materials, or time-sensitive service, all of which can increase the final cost beyond standard repair pricing.

Urgent window repairs, such as broken glass after a storm or security concerns, can require same-day, evening, or weekend service. Emergency calls typically add $100 to $200 to the total cost due to overtime labor and expedited scheduling.

Second-Story or Ladder Work

Windows located on upper floors or in hard-to-reach areas require ladders, scaffolding, or safety harnesses. This added risk and setup time increases labor costs, usually adding $75 to $250 depending on window height and accessibility.

Custom or Specialty Glass

Custom-sized, tempered, tinted, or energy-efficient glass costs more than standard panes and may need to be specially ordered. Repairs involving specialty glass typically add $150 to $500+ to the total cost, depending on size and glass type.

Historic Home Window Repairs

Older or historic homes often require careful repairs to preserve original materials or meet preservation guidelines. Matching wood profiles, glass styles, or hardware increases labor time and material costs, with repairs commonly ranging from $200 to $600+.

Permit Requirements

While permits are uncommon for standard window repairs, some municipalities require them for structural changes or historic properties. Permit fees typically range from $50 to $200, and may also require inspections that add time and cost to the project.

Tips for Saving on Window Repairs

• Address problems early to prevent damage from spreading.
• Repair instead of replace when damage is isolated to a part or component.
• Get 3 to 4 quotes from local window pros so you can find the best deal.
• Bundle repairs by fixing multiple windows during the same visit.
• Maintain seals and tracks to extend window lifespan.

Preventive maintenance and early intervention can significantly reduce repair costs over time.

Is it Worth it to Repair Windows?

Window repair is usually worth it when the damage is minor, localized, and the window is relatively new. Repairs can restore energy efficiency, improve comfort, and delay the need for full replacement.

Replacement may be the better investment if repair costs exceed 50% of replacement cost, the window is over 20 years old, there is extensive rot or warping, or repeated seal failures are affecting comfort and energy bills.
