Repair vs. Replacement Decision
When Glass-Only Replacement Makes Sense
Good candidates for glass replacement:
- Frame in excellent condition
- Hardware functions properly
- No rot or structural damage
- Window operates smoothly
- Weatherstripping intact
Glass damage requiring replacement:
- Cracked or broken panes
- Failed seals with foggy glass

When Full Window Replacement is Better
Replace entire window when:
- Frame is rotted or damaged
- Window doesn’t operate properly
- Multiple component failures
- Energy efficiency requires frame upgrade
- Repair costs approach replacement costs
Signs you need full replacement:
- Visible frame deterioration
- Air leaks around frame
- Difficult or impossible operation
- Multiple failed repairs
- Windows over 20 years old with issues
Long-term value considerations:
- Glass replacement: 5-15 year solution

The Bottom Line
Window glass replacement costs $150-$600 per window for most homeowners, with double-pane insulated units averaging $300-$500 installed. Single-pane glass is cheaper at $75-$250, while specialty or custom glass can exceed $800.
The decision between glass-only replacement and full window replacement depends on frame condition, window age, and overall performance. Glass replacement makes sense when frames are sound and functional, saving 30-50% compared to full window replacement.
Professional installation is recommended for double-pane units, large glass, or upper-story windows. DIY is feasible for accessible single-pane replacements if you have experience and proper safety equipment.
Get multiple quotes, verify contractor credentials, and understand exactly what’s included in pricing. Hidden costs like frame repairs or difficult access can add 20-30% to base estimates, so budget accordingly.
