How to stop a windshield crack from spreading

The worst thing about a windshield crack is that it can happen anywhere and at any time. Often, you may not even notice it for a few days. And that means that the crack can slowly start to spread without your knowledge until it resembles a spider’s web. When a crack reaches this point, it is a serious danger to the safety of your car, yourself and other road users. Worse still, it will require your windshield to be replaced in full, rather than quickly repaired. In this post, we’ll show you what you can do to stop a crack from spreading.

Understanding windshield design

You may have noticed that the majority of thieves will always choose to break a car’s door windows and never the windshield if they want to get inside. A big reason for this is because the windshield is built differently from the rest of your car’s glass. It’s significantly stronger and tougher because it is composed of two layers of thick glass with laminated rubber in the middle. The rubber lamination keeps both layers of glass firmly in place making it exceptionally resilient to extreme impact.  It’s why when a windshield gets hit with a baseball bat in films, it never shatters.

Obviously, your car’s windshield has certain limitations but it is capable of enduring a great deal of force. Car manufacturers made sure that windshields are robust enough to withstand potential collisions and are engineered to prevent shrapnel or broken glass from exploding inside the car.

In terms of cracks, the damage will most likely involve only the exterior glass layer although there are rare instances when sharp items will penetrate through to the interior layer. Nevertheless, whatever the extent of the crack may be, water may be able to pass through, compromising the structural integrity of your glass in the process. Dirt, ice, and moisture can also slip through the cracks affecting driving visibility.

For all these reasons, you should address any crack in your windshield, big or small, ASAP to prevent further damage from developing.


Stopping Windshield Cracks in their Tracks

If you notice a crack in your car’s windshield,  there are several steps you can take to stop it from spreading.

The most sensible step is to take your car to an auto glass repair shop as soon as you notice the crack.

If the crack doesn’t penetrate the rubber lamination and inner glass layer, the cost of repairing a crack, even quite large ones, is surprisingly cheap. Better still, the repair may be covered by your auto insurance.

Ideally, you will want to rely on a professional windshield repair and replacement service who will evaluate the extent of the crack and come up with the ideal repair solution based on your windshield’s inherent design and material. Every glass material and windshield design responds uniquely to force based on the location and amount of force delivered, which means every restoration solution will be different for every windshield crack.


Who’s to blame when your windshield becomes cracked?

In instances wherein your windshield becomes chipped, it’s important to know who will carry the blame and if your insurance company will cover the damage. Here’s how things work when it comes to who’s at fault:

Anything that is found on the road is considered as “natural hazard”. So if another vehicle hits a stone that bounces to your windshield, it would be deemed as a natural event.

The same is true even for objects that aren’t usually found on the ground. As soon as they have touched the ground they are deemed a natural hazard. So if a vehicle’s cargo falls on the ground and ricochet’s onto your windshield, neither would be at fault.

However, if the object drops directly from the vehicle and lands on your windshield, then the fault belongs to the driver in front.

If you spot a crack, call your auto insurance company immediately to see if you are covered. Then call a leading car windshield replacement center, like A Plus. Regardless of what your insurance say, the quicker you can repair a crack, the cheaper it will be.
