If you have a crack in your windshield, then sometimes it's ok to hold off on getting it fixed or repaired. But in other cases, the clear, best answer is to take it into an auto glass repair shop. Here are some cases where it's definitely time for auto repair. 

If It's Affecting Your Visibility

First of all, a crack may not be such a big deal if it isn't interfering with your ability to see everything coming your way. For instance, a crack near the corner of the glass on the passenger's side may not affect you that much. But if it's a crack in your line of sight, even a small blemish could be mistaken for an obstacle and cause you to gut react in a poor way. It could also obscure a real obstruction that you need to avoid. Go ahead and get the windshield checked out by a specialist right away. 

If It's Covered Under Your Insurance

Another sign to go ahead with windshield replacement is if it's covered under your insurance. This isn't always the case, but some insurers will allow you to add windshield coverage to your plan for a small fee. It's worth it to find out whether you're covered or not, and what the costs of insured replacement vs out-of-pocket replacement would be. 

If the Crack is Sizable

Another time when windshield repair is an important option is when the crack is very large. For instance, if your windshield crack is larger than a quarter or longer than an inch, you may want to get it checked out. Such a large crack can compromise the strength and protection of your safety glass, and in the case of a collision, the safety glass may not hold as it's supposed to. 

If a Self Fix is Not Holding

Finally, it's time to go into the shop if your self fix is not working out. There are several temporary fixes such as glues and even simple duct tape. If you've found a cheap fix but the glass crack continues to spread, do yourself a favor and take the car into the shop before the glass breaks all the way through. You wouldn't want to risk this happening while you are in the car. 

In these four cases, getting your windshield fixed at a glass repair shop is a no-brainer. In other cases, it can still pay to have a windshield specialist take a look. Check out a site like http://www.centralglassutah.com to get in touch with a windshield repair company.
