How to Identify a Repairable Crack vs. When to Replace the Windscreen
Knowing how to identify a repairable crack versus when to replace the windscreen is essential for keeping your vehicle safe and roadworthy. Many drivers in Australia dismiss small chips and cracks as minor issues, but the decision to repair or replace has both safety and cost implications. Understanding the difference can help you act quickly and avoid unnecessary risks on the road.
Generally, small chips and cracks can be repaired if they meet certain conditions. As a rule of thumb, chips smaller than a 20-cent coin and cracks less than 75–100mm long are often suitable for repair, provided they are not in the driver’s direct line of sight. Modern repair techniques use resin that restores the structural strength of the glass and prevents the damage from spreading further. These repairs are quick, affordable, and often covered by insurance, making them the preferred option when possible.
However, there are clear situations where replacement becomes necessary. If a crack extends to the edge of the windscreen, it compromises the structural integrity of the entire glass, making it unsafe to repair. Similarly, large cracks longer than 150mm or multiple chips clustered together are usually beyond repair. Damage in the “critical vision area” directly in front of the driver is also a common reason for replacement, as even a repaired chip may leave a blemish that affects visibility.
The presence of Advanced Driver Assistance Systems (ADAS) adds another factor. Many modern vehicles have cameras and sensors mounted on the windscreen, and damage near these areas may interfere with their operation, requiring a replacement rather than a repair.
Ultimately, the decision should always be guided by safety. A professional technician can assess the size, depth, and location of the damage to determine the best course of action. By understanding when repair is sufficient and when replacement is unavoidable, Australian drivers can make informed choices that balance cost with the vital need for safety on the road.
