Many drivers face the frustrating situation where a small stone hits the car's windshield while driving, causing a crack that might seem minor at first. This raises a crucial question: Is repairing the crack enough, or is a full windshield replacement the safer option? In this comprehensive guide by YallaMotor, we explain when repair is sufficient, when replacement is necessary, and provide practical steps to handle the situation immediately.
When Can a Windshield Crack Be Repaired?
In some cases, cracks can be repaired without the need for a full windshield replacement. The key factors are the size and location of the crack. If the crack is small and outside the driver’s direct line of sight, repair is usually possible.
- The crack does not exceed the diameter of a small coin.
- It is at least 10 cm away from the edge of the glass.
- The damage is only on the outer layer of the windshield.
- It is not within the driver’s direct field of vision.
“Smart Repair” Technology for Windshield Cracks
“Smart Repair” technology is used for minor damages, where the crack is filled with a special resin and cured with ultraviolet light to restore strength. This service is available at specialized workshops, and DIY repair kits can also be purchased from stores.
Although the process is straightforward, seeking professional help remains the best choice to avoid future issues and ensure optimal safety.
When Is Windshield Replacement Necessary?
There are situations where repair is not an option and replacement is mandatory to maintain your safety.
- The crack is larger than 5 mm.
- The crack is located directly in the driver’s field of vision.
- The crack is on the side or rear windows, which cannot be repaired.
- The crack has spread in multiple directions, compromising the integrity of the glass.
Why Is Replacement Sometimes Essential?
The windshield is a crucial structural component that contributes to the car’s integrity and provides protection during accidents. Any weakness in the glass can reduce safety in the event of a collision.
How Is a Windshield Crack Repaired in Workshops?
Auto glass workshops typically follow these steps for crack repairs:
- Thoroughly clean the cracked area to remove dust and moisture.
- Inject a special resin into the crack using a precise applicator.
- Cure the resin with ultraviolet light for maximum hardness.
- Remove excess resin and polish the surface to restore a natural finish.
This process usually takes between 30 minutes to an hour, but it requires precise equipment and skilled technicians.
What Should You Do If a Crack Occurs While Driving?
If you hear a sudden impact while driving followed by a crack in the windshield, act quickly but remain calm:
- Avoid sudden braking after the impact.
- Stop at the nearest safe location to assess the damage.
- Apply clear tape over the crack to prevent dust and moisture from entering.
- Head directly to a certified service center for inspection.
Is a Crack an Immediate Danger?
Usually, a crack does not pose an immediate threat to driving safety, but it can worsen over time due to vibrations and temperature changes. That’s why it’s important to address it promptly before it turns into a complete break.
Cost of Windshield Repair and Replacement in the UAE
The cost of service varies based on the car type and the extent of the damage:
- Small crack repairs start from AED 200.
- Windshield replacement can range from AED 1,200 to 3,000, depending on the model.
- Luxury cars like Mercedes or BMW will incur higher costs.
It is always best to contact authorized service centers for an accurate quote and to ensure genuine glass is used.
Tips to Prevent Windshield Cracks
Prevention is better than cure. Here are steps to reduce the risk of windshield cracks:
- Keep a safe distance from the vehicle ahead, especially trucks that scatter gravel.
- Avoid speeding on roads with loose stones.
- Use a protective cover when parking in construction areas or on unpaved roads.
- Regularly inspect your windshield to detect small cracks before they expand.
Conclusion
If the crack is small and outside the driver’s direct sight, resin-based repair is sufficient. However, if the crack is large or in a sensitive area, immediate replacement is necessary. Prompt action preserves your safety and saves you from higher costs later on.
