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+ for complex repairs. Most homeowners pay around $200 to $400 per window for professional service, depending on the issue and the window’s size, materials, and location.
Window repair cost at a glance:

• Average per window: $200 to $400
• Typical range: $75 to $650+
• Most common mid-range repairs: cracked glass, failed seals, balance/hardware issues
• Repair vs. replace rule of thumb: compare replacement if repairs reach 40% to 50% of replacement cost or $400 to $600+ per window

What you ultimately pay depends on the window’s construction, materials, size, and accessibility, plus how long the problem has gone unaddressed. Catching issues early helps keep repairs affordable, while delays can allow air leaks, moisture intrusion, or structural damage to spread.

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

Window Repair Costs Vary by ZIP Code

Labor rates, glass availability, and seasonal demand can significantly impact what you’ll pay. A $250 glass repair in one area may cost $500+ in another — especially for insulated or specialty glass.

Factors That Impact Window Repair Cost

Several factors influence the total cost of repairing a window. Repairs typically cost more when insulated glass units are involved, parts are specialized, or the window is difficult to access.

• Type of damage (glass, seal, hardware, or frame)
• Window size and style
• Frame material
• Single vs. double-pane construction
• Accessibility (upper floors or hard-to-reach areas)
• Labor rates in your area

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 often the most affordable, while glass and seal repairs tend to cost more because they may require replacing an insulated glass unit or custom pane.

Cracked or Broken Window Glass

Cracked glass can be caused by impact, temperature changes, or structural shifting. Even small cracks can spread and reduce safety and insulation. Repair costs typically run $150 to $400, with larger panes and insulated units costing more.

Foggy Windows or Failed Seals

If you notice condensation or fog between panes, the seal has likely failed. This allows moisture into the insulated glass unit and reduces energy efficiency. Seal failure usually requires glass unit replacement rather than resealing, with typical costs of $200 to $500.

Drafts and Air Leaks

Drafts often point to worn weatherstripping, failed caulking, or small frame gaps. These are usually among the most affordable fixes, often costing $75 to $200 when addressed early.

Stuck, Jammed, or Hard-to-Open Windows

Operational problems are commonly caused by balance issues, track damage, or warped components. Repairs typically cost $100 to $250, depending on window type and the parts required.

Broken Locks, Latches, or Hardware

Hardware repairs are often straightforward and usually cost $75 to $200, depending on the window style and replacement part availability.

Frame Damage or Rot

Frame damage — especially wood rot — often stems from long-term moisture exposure. Minor repairs may run $200 to $400, while extensive decay can push costs higher and may make replacement the better option.

Window Repair Cost by Window Details

Repair pricing can shift based on how the window is built and installed. Larger or more complex styles (bay/bow, skylights) and materials that are harder to restore (wood, specialty composites) tend to cost more.

Notes on window types

• Single-hung repairs are often lower-cost because only one sash moves.
• Double-hung windows may need balance repairs or sash alignment on both panels.
• Casement repairs often involve hinges, cranks, and locking hardware.
• Sliding windows commonly need roller/track repairs and realignment.
• Bay and bow windows can cost more due to multi-panel construction.
• Skylights often require added labor due to roof access and leak prevention.

Window Repair Labor Costs

Many window repair pros charge hourly or use flat-rate pricing. Labor tends to rise when the repair involves glass replacement, specialized parts, or difficult access.

What Makes Up Window Repair Costs?

Understanding the breakdown helps you compare estimates and avoid unnecessary upsells.

Pro Tip: If insulated glass has failed, ask whether replacing the full sash costs significantly more than replacing the glass unit — or whether replacement makes more sense overall.

Additional Window Repair Costs to Consider

Some jobs require extra materials, specialized glass, or time-sensitive scheduling. These add-ons can increase the final price beyond standard repair costs.

• Emergency or after-hours service: often adds $100 to $200.
• Second-story or ladder work: commonly adds $75 to $250 depending on access and safety setup.
• Custom or specialty glass: may add $150 to $500+ for custom-sized, tempered, tinted, or energy-efficient glass.
• Historic home repairs: often run $200 to $600+ due to matching materials/hardware.
• Permits: uncommon for standard repairs but may apply for structural changes or historic properties ($50 to $200).

Storm-Damaged Windows: Repair or Replace?

Storms, hail, falling branches, and high winds can cause more than visible cracks. Impact damage can weaken seals, compromise insulation, and create long-term moisture problems.

Common storm-related window damage

• Cracked or shattered glass
• Foggy panes after impact
• Bent or warped frames
• Seal failure from pressure changes
• Water intrusion around flashing

If storm-related repairs exceed $400 to $600 per window, comparing replacement options may help you avoid repeat issues — especially if your windows are older.

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 to compare pricing.
• 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 damage is minor, localized, and the window is relatively new. Repairs can restore energy efficiency, improve comfort, and delay full replacement.

Replacement may be the better investment if repair costs exceed 40% to 50% of replacement cost, the window is over 20 years old, there is extensive rot or warping, or seal failures keep returning.

When Does Window Repair Stop Making Financial Sense?

You may want to compare replacement options if:

• Glass seal failure keeps recurring
• Frame rot or structural damage is spreading
• Repairs exceed $400 to $600 per window
• Multiple windows need glass or seal replacement
• Your windows are 15 to 20+ years old

New energy-efficient windows can reduce drafts, improve comfort, and lower heating and cooling costs — often offsetting higher upfront costs over time.
