A small windscreen chip can become a longer crack. Changes in temperature, vibration from the road and pressure on the glass can all put stress around a damaged spot. Dirt or moisture entering the chip may also make a later repair less straightforward.
What can make damage spread?
- Rapid temperature changes: heating or cooling the cabin quickly can create temperature differences across the glass.
- Road vibration: potholes, rough roads and repeated bumps can stress an existing chip.
- Pressure and impact: slamming a door or another stone strike can worsen damage.
- Moisture and dirt: contamination can enter the damaged area and affect repairability.
These factors do not mean every chip will spread, but it is difficult to predict how a particular windscreen will respond. A technician can assess its size, depth, location and any cracks that have formed.
What to do while you arrange an assessment
Take a photo of the damage when the car is parked. Avoid pressing on the chip, slamming doors, or directing very hot or cold air at the windscreen. If you use a temporary cover to keep dirt out, do not use a material or adhesive that could damage the glass or obstruct your view. Arrange a professional assessment as soon as practical.
A repair may be suitable for some small chips. High Class Windscreens says its on-site repair takes about 30 minutes per chip in typical cases, and a faint mark may remain. Larger damage, cracks at the edge, or damage in the driver’s primary viewing area may need replacement instead. The technician will advise based on the actual damage.
