All it takes is one small chip in the windshield before it becomes a full-fledged crack. Even though a chip may appear small, it can quickly become a more serious issue. Here’s the latest information on windshield repair and how to prevent a windshield crack from escalating into a more serious safety concern.
How big of a windshield crack can be repaired?
A damaged windshield may not always require replacement. If your car’s windshield has minor damage, it can often be repaired. But because even a minor crack can grow into a bigger problem, it’s important to address the issue as soon as possible. First, check with your insurance company to see if you have windshield repair coverage. In some cases, the carrier may even waive your deductible for windshield repairs. [1]
Types of windshield cracks
Windshield cracks come in all shapes and sizes, but it’s imperative that you get any type of crack fixed as soon as you can. This will help you avoid further damage and help ensure safety on the road. Let’s review the variety of chips and cracks you may encounter.
- A bull’s-eye crack is a large, round crack that occurs in the center of the windshield. It’s usually caused by road debris such as rocks or gravel. Because it may be in the driver’s direct line of sight, it should be repaired in a timely manner.
- A star break crack is a burst of short, branching cracks that resemble a star. It’s caused when an object or debris strikes the windshield. It’s best to get this crack fixed quickly because it could extend across the windshield, causing further damage that may eventually lead to a full replacement.
- A half-moon crack looks like the crescent shape of the moon. It’s often caused by the impact of a blunt object. This type of crack is easier to fix than others.
- A combination crack is a blend of a bull’s-eye and a star crack and they’re difficult to fix. You’ll need a skilled professional to fix this type of crack and avoid causing further windshield damage.
- Other cracks that begin or end at the windshield’s edge usually cannot be fixed, and a full windshield replacement may be necessary. [2]
Tips for fixing a cracked windshield
After you’ve evaluated the damage to your windshield, you may be debating between having it professionally fixed or fixing it yourself. Note that it’s important to take the proper precautions, buy a DIY repair kit and follow best practices if you attempt to fix this on your own. Let’s review some details to consider before you make the decision.
1. Determine when to worry about a cracked windshield
First, where’s the crack located? Is it off to the side, or is it obscuring your view? If it interferes with your ability to see the road, you should deal with even a tiny crack immediately. However, if it’s not impairing your ability to see the road, grab a ruler and measure the length of the chip or crack. This can help determine whether you can repair the windshield or need professional repair or replacement.
2. Clean the area around the windshield crack
One of the most important things to guard against is dirt. If dirt gets into the crack, it can complicate a simple repair. But that doesn’t mean you should head for the car wash or reach for a bucket. If water seeps into the crack, what began as a small repair can easily become a complete replacement. Instead, you can temporarily keep dirt and moisture away from the crack by cleaning the damaged area and applying a piece of clear packing tape, which is strong but won’t obscure your view. Also, try to avoid potholes and damaged roads and slamming your doors too hard. Car vibrations can cause a small chip to spread. [3]
3. Park indoors to avoid windshield crack growing due to the elements
Sun, snow and rain all have the potential to cause the windshield chip or crack to grow. If possible, park your car under cover, where it will be protected against elements like the sun, which can cause the windshield to crack further or expand. If you don’t have a garage, try parking in a shaded spot. [3]
4. Avoid windshield crack spreading from temperature extremes
Likewise, extremely cold weather is not good for a cracked windshield because glass contracts when it gets cold. Refrain from putting your defroster or heater on high before you can tend to the issue. A temperature change of 30 degrees or more can make things worse, so don’t delay in getting a cracked windshield repaired, especially as winter is approaching. [4]
5. Use a windshield crack repair kit
If you decide to fix the issue on your own, it’s best to buy a repair kit. For cracks less than 3 inches, purchase a kit that includes an epoxy resin. Epoxy has an expiration date, so check the manufacturer’s date and choose a kit that’s less than 6 months old. Check the instructions to understand any additional items you’ll need such as a razor or utility knife, glass cleaner and cloth. When you’re making the repair, wear gloves and protective eyewear and stay in a well-ventilated area. Above all, keep safety in mind at all times and follow the instructions carefully. [1]
Are cracked windshields covered by insurance?
The short answer to whether damaged windshields are covered is: It depends on your insurance carrier and the policy you have. Check out more details about windshield replacement and insurance claims. It’s important to note that if you leave a crack unrepaired, it can spread or become a safety concern. Thus, get an evaluation right away.
Beyond repairing a cracked windshield, performing regular car maintenance is vital to sustaining your car in the long term. Check out the ultimate car maintenance schedule and keep your ride up to date. Finally, ensure that you and your vehicle are always protected with auto insurance.
