Symptoms
- Small chip, pit, or star-shaped mark on the windshield
- May be accompanied by a small crack radiating outward
- Chip location visible from inside or outside the glass
- No immediate change in visibility unless it's in the driver's direct line of sight
Likely causes
- CommonRock or road debris impactSmall stones kicked up by other vehicles are the most common cause of chips.
- PossibleTemperature stress on existing minor damageRapid heating or cooling, like defrosting a cold windshield fast, can worsen an existing chip.
- PossiblePre-existing chip left unrepairedChips that sit too long collect dirt and moisture, making a clean repair harder.
What to do
- Cover the chip with clear tape as soon as possible to keep dirt and moisture out until it's repaired.
- Avoid extreme temperature changes on the glass, like blasting hot defrost on a very cold windshield.
- Get it repaired as soon as you can, ideally within a few days, since chips can spread with time, vibration, or temperature swings.
- Many auto glass shops or mobile services can repair a small chip in under an hour, often at low or no cost if you have comprehensive insurance.
- Do not attempt to repair a chip larger than a quarter-sized area, in the driver's direct line of sight, or with cracks radiating more than a few inches; these typically need full replacement instead.
- Check your insurance policy, since many comprehensive plans cover windshield chip repair with no deductible.
