How to Stop a Windshield Crack from Spreading

Car problems happen. Anyone with a car should know that, at some point, something is going to go wrong!

One of the most annoying issues you may face with your car is a windshield crack.

As a car owner, you should learn how to stop a windshield crack from spreading to be sure that the problem doesn’t become worse.

Keep reading to learn more about what to do when you notice that small crack in your windshield.

Is a Cracked Windshield Dangerous?

Although having a cracked windshield may just seem like a slight inconvenience, it actually can be pretty serious. If you don’t deal with the problem when it starts, it will get worse and worse. Eventually, it may become unsafe to drive with the crack in your windshield and you could even get in legal trouble.

The windshield on your vehicle has a really important job. It protects you as you drive from things that may fly into the front of the car, it provides a barrier from the elements, and it also keeps you safe in the event of an accident. The windshield will help to minimize the impact in a front-end accident and can protect you or other passengers.

A windshield that has cracks or even holes is not going to be able to do any of these jobs effectively. For this reason, you want to make sure that you take care of the crack you find in your windshield as soon as you are able to do so.

Cracks can also be really distracting to the driver. In addition to this, it just doesn’t look very good either!

It isn’t always necessary to replace the entire windshield when you notice a crack. In some cases, you may be able to prevent some minor cracks from getting worse on your own.

How Bad is the Actual Crack?

If the crack is really bad, you likely may need to consider getting a new windshield. As we stated earlier, however, you may not need to replace the whole windshield if you notice a small crack. 

Look at the windshield closely to see how bad the crack in your windshield really appears to be. You may be able to fix the crack on your own or take it to a professional to have it assessed more closely.

If it is large enough to cover a good portion of the windshield, you may not be able to salvage it. If it is only a small dot, however, you probably can find an easy fix.

You need to consider actually measuring the size and depth of the crack. If it is twelve inches long, half an inch in width, or has been there for a long time, you may want to go ahead and replace the entire windshield.

How to Stop a Windshield Crack from Spreading

When you first notice a crack, you must start to take preventative measures to ensure that it does not get worse. There are a lot of little things that may cause it to happen, so you should be on the lookout.

You don’t want to allow any water or dirt into the crack because this will cause it to get larger and become more serious. There are simple things you can do to prevent this from happening.

Even though you can hire a professional to help you, many people would rather try to save a little bit of money and do the job themselves. If this is the case, be sure that you do it correctly!

Here are some tips to prevent the crack from spreading and worsening over the whole windshield. 

1. Superglue or Clear Nail Varnish

Although it may sound odd, using super glue or nail varnish to plug the crack is a common solution.

You can clean it off first with glass cleaner and paper towels. After this, you will use the superglue or the clear varnish to try to fill in the crack and make it even with the rest of the surrounding glass. 

Another great step to take after trying this and letting it dry is to put clear packing tape on top. This will ensure that there is no chance of dirt or other debris getting into the crack.

With this solution, you still will want to get it looked at by a professional eventually. This simply buys you a little more time and lets you ensure that the crack won’t get any worse before you can get it fixed.

2. Try a Windshield Repair Kit

This is a pretty obvious response, but there are repair kits that you can buy at a variety of stores that will help you repair the windshield. 

The good news with this option is that, if it is done right, you may not need to get your car looked at by a professional at any point. This may be all that you need to do!

The problem, however, is that doing it wrong can cause your crack to become much, much worse. You must be comfortable using tools and boring a hole into the glass for this option to work for you.

3. New Temperatures

Glass will either expand or shrink in certain temperatures. Although you can’t see it happen, it does happen!

As you may imagine, temperature changes causing the glass to move will worsen the crack. This is why you want to keep the vehicle and the windshield in the same type of temperature until you are able to get the crack repaired.

4. Park in the Shade

This is entirely related to the last point. By parking in the shade, you are less likely to expose your windshield to high amounts of heat. This will help ensure that the glass is not going to expand.

5. Get It Professionally Fixed 

In most cases, you will likely need to have your windshield examined and repaired by a professional at some point.

It generally is less expensive to get the windshield repaired than it is to get it replaced. For this reason, it is always smart to try and get your windshield looked at sooner rather than later.

Protect Your Windshield

Now that you know how to stop a windshield crack from spreading, you can be more prepared for dealing with this issue.

Auto owners always must be prepared for anything that may happen to their vehicle. This includes the possibility of their windshield cracking at some point.
