Your car’s windscreen isn’t just a piece of glass—it’s a vital safety feature that provides visibility and supports structural integrity. So when a chip or crack appears, it’s essential to address it quickly. But how do you know whether to replace windscreen or a simple chip repair is enough?
Understanding the difference can save you time, money, and ensure your safety on the road.
When Is Chip Repair Enough?
Small chips, especially those caused by flying stones or road debris, are quite common. Most may be readily fixed without replacing the entire windscreen if detected early. In general, windscreen chip repair is possible if:
- The chip is smaller than a $2 coin
- It’s not located in the driver’s direct line of sight
- The maximum number of chips is two or three.
- The windscreen's edge has not been affected
- There are no cracks radiating from the chip
In order to strengthen and increase clarity, chip restoration entails injecting a transparent resin into the damaged region. It’s quick, cost-effective, and often covered by comprehensive car insurance policies.
When Windscreen Replacement Is Necessary
There are situations where a repair just won’t cut it, and a full windscreen replacement becomes necessary. Consider replacement if:
- The crack is longer than 7cm or runs across the windscreen
- The damage is near the windscreen edge, where structural integrity is compromised
- The surface shows multiple chips or a spiderweb of cracks.
- The damage has permeated the glass's inner and exterior layers
In these cases, continuing to drive with a compromised windscreen increases the risk of glass shattering or failing during an accident. A full replacement ensures the structural safety of your vehicle.
The Importance of Timely Action
Ignoring minor chips can lead to major problems. Temperature changes, vibrations from driving, and moisture can cause chips to expand into full cracks over time. What could have been a quick repair turns into a more expensive and time-consuming windscreen replacement.
Acting quickly, no matter the case, ensures your safety and avoids further issues. If you’re unsure, it’s always best to consult a professional technician who can inspect the damage and recommend the safest solution.
