Tips on How To Prevent Windshield Crack From Spreading

Windshield cracks can be incredibly frustrating. Not only do they obstruct your view while driving, but they can also be expensive to fix.

And if left untreated, they can spread quickly and cause even more damage. Fortunately, there are a few things you can do to prevent windshield cracks from spreading.

By following these tips from auto glass repair professionals, you can keep your windshield in good condition and avoid costly repairs.

Buy a Windshield Repair Kit

Cracks can quickly become larger, making the windshield more difficult to see through and increasing the risk of damage from flying debris. One way to prevent windshield cracks from spreading is to buy a windshield repair kit. These kits contain a resin that is used to fill in the crack, bonding the glass together and preventing the crack from getting bigger. 

To use a windshield repair kit, first clean the area around the crack with alcohol to remove any dirt or debris. 

Then, insert the tip of the resin tube into the crack and squeeze the trigger to dispense the resin. Use the included curing strip to hold the resin in place, and then wait for the resin to harden. 

Once the resin has hardened, the crack should be much less visible and the risk of it spreading will be greatly reduced. If the crack is still visible, you may need to repeat the process. 

Windshield repair kits are available at most auto parts stores and are relatively inexpensive. Take a look at the best windshield repair kits for 2023. They are a quick and easy way to prevent small cracks from becoming big problems. 

Always Park Your Car in Shade

If you have a crack in your windshield, be careful of exposure to sunlight, snow, and rain. These elements can cause the crack to grow bigger, making it more difficult (and expensive) to repair. If possible, try to keep your car out of direct sunlight, and cover the crack with tape or another material when it’s raining or snowing.

Avoid Drastic Temperatures

If you have a windshield crack, avoid exposing your windshield to drastic changes in temperature. This can cause the crack to spread. If it’s a cold day, try to park in a garage or in the shade. If it’s a hot day, try to avoid parking in direct sunlight. You should also avoid using your defroster, as this can also cause the crack to spread.

Get Your Windshield Repaired

When you get a crack in your windshield, it can be very tempting to just ignore it. After all, it’s not like the crack is going to cause any immediate harm, right? Wrong. If you don’t get that crack repaired as soon as possible, it could end up spreading. And once it starts spreading, it’s only a matter of time before your windshield is completely ruined. 

So, how do you prevent a windshield crack from spreading? The best way is to get it repaired as soon as possible. There are a few different ways to do this, but the most effective is to take it to an auto glass repair professional. They will have the tools and experience necessary to properly fix the crack, so that it doesn’t have a chance to spread.


As you can see, there are many ways that you can prevent your windshield cracks from spreading. By following the tips above, you can extend the life of your windshield and therefore avoid the need for expensive repairs.
