A windshield crack is a terrible experience. No matter how small the crack may be, you know it’s a problem and you know you need to get it fixed right away. That's when you start thinking about the cost of having it fixed, and the time it will take, and you probably groan right out loud. But windshield crack repair can be a lot easier and quicker than you think. Sometimes, you can repair a crack in 10 minutes or less using very simple techniques.

First Steps

As soon as you get a crack, you need to get somewhere to stop its spread. A tiny crack can turn into a ruined windshield in very short order. If moisture gets into the crack or freezing weather hits the windshield, that crack will grow and expand and you will end up needing a full windshield replacement. Dirt and debris can also get into the crack, which can eliminate any possibility of DIY repair.

Apply epoxy or acrylic directly onto the crack. This will fill the crack or the chip and keep it from spreading. You will notice a dramatic improvement in the crack after you do this.

Don't have epoxy or acrylic handy? You probably have clear nail polish. Grab it and swipe it over the crack to keep out moisture and dirt. This will serve as a band-aid until you can perform your repair.

Once you know that at least the crack will not get worse, you still don't want to waste a lot of time in repairing it. Luckily, it isn't difficult to move onto the next step and hopefully completely fix that windshield crack.

How Big Is It?

Large windshield cracks cannot be repaired with DIY methods. For larger cracks, you will have to go to a repair technician. Many companies specialize in auto glass. This repair may be costly, however, so it's always worth it to do the repair yourself if possible.

As a general rule, if your crack is longer than the length of a standard U.S. dollar bill then you cannot repair this yourself.

You also cannot repair cracks that are in certain areas of the windshield. Does the crack pass through a radio antenna or something else embedded in the glass? If so, you need to consult with a technician instead of repairing this crack.

If the crack is complex and is actually many different cracks, repairing it yourself probably isn't an option. A crack containing a large chip, or several, may be too extensive to repair as well.

Repairing the Crack

Windshield repair kits are available at any home improvement store and even on Amazon, which can send you the kit overnight. These kits are incredibly easy to use and extremely effective. Simply follow the directions to the letter. Before you do anything to the windshield, make sure it's dry. If needed, grab a hairdryer and use it to completely dry the windshield.

If you can't repair the crack yourself or you're unsatisfied with your DIY job, you will have to go to a repair technician. Explore your options to make this a little more bearable financially. It's possible that your car insurance will cover all or part of the cost of the repair. Consult with them to find out before you take the plunge and pay for the entire cost of the repair yourself.
