When Can a Windscreen Chip Be Repaired?
A windscreen chip can often be repaired with resin injection if it meets all of these criteria:
- Size: Under 50mm in diameter (smaller than a $2 coin)
- Location: Not in the driver's direct line of sight (the critical vision area in the centre of the windscreen)
- Depth: Only the outer layer of laminated glass is damaged
- Type: Bullseye, star, or small crack — not a long spreading crack
If your chip meets these criteria, resin injection is a fast, cost-effective solution that restores the glass's structural integrity and stops the crack from spreading.
When Does a Windscreen Need Replacement?
Replacement is the only safe option if:
- Size: The damage is larger than 50mm or has spread into a long crack
- Location: The chip or crack is in the driver's critical vision area
- Edge damage: The crack extends to the edge of the windscreen
- Multiple cracks: There are three or more cracks from a single impact
- Depth: Both layers of the laminated glass are damaged
- Contamination: The chip is filled with dirt or water that cannot be cleaned out

Insurance: Repair vs Replacement
Most comprehensive insurance policies in NZ cover both chip repair and windscreen replacement. The key difference:
- Chip repair: Often covered with no excess and no impact on your no-claims bonus
- Replacement: Usually covered with nil excess (you pay nothing) or just your windscreen excess ($100-$500)
We handle the insurance claim for you either way. Just give us your policy details and we invoice your insurer directly.
