Types of Window Cracks
1. Small Hairline Crack (< 3 inches)
Can it be repaired? Temporarily, yes. Apply clear caulk or epoxy resin to fill the crack. This is a temporary fix (3–6 months). Cost: $25–$75. Limitation: The crack will still be visible; it doesn’t restore strength.
2. Large Crack (3–12 inches)
Can it be repaired? No. You must replace the pane. Remove the broken pane, cut a new pane to exact size, install with glazing compound and hardware. Cost: $250–$400 (single pane); $300–$500 (double pane).
3. Crack Extending to Window Edge
Can it be repaired? No. You must replace the pane. Full pane replacement. Cost: $250–$500.
4. Multiple Cracks (Spider Web Pattern)
Can it be repaired? No. You must replace the pane. Full pane replacement. Cost: $250–$500.

Our Recommendation
If the crack is larger than 3 inches or running toward the edge — replace the pane. It’s worth the extra investment.
