2 Reasons Why You Should Never Repair A Cracked Windshield Yourself

While driving along the highway, a rock or other object may have landed on your windshield and cracked the glass. If the damage does not seem too severe, you may decide to try fixing the crack yourself. However, there are a couple of reasons why you should leave the job up to a professional service instead of attempting a repair job at home.

1.  Crack May Get Bigger While You Are Attempting to Repair It

When you decided to try fixing your cracked windshield yourself, you may have done so because the crack was not too big and you feel that a small amount of filler should do the trick. However, unless you have the proper tools, you may end up making the crack bigger while you are trying to fix it.

Especially if the crack is towards the middle of the windshield, you may have to lean on the glass to reach it with the tube of filler. Because the glass's structural integrity has already been compromised by the crack, even the slightest amount of pressure in the wrong spot could make the crack grow.

If you were to continue trying to fix the glass after this happens, there is always the possibility that the increased damage and pressure could cause the windshield to shatter.

2.  Do-It-Yourself Windshield Repair Kits Do Not Fully Fill the Crack

Another reason why you should not try to fix your own windshield is that the filler contained in do-it-yourself (DIY) kits may not fully fill in the crack. While it can help conceal the crack, it might not bind the broken areas of the glass together fully.

Because the filler might not actually bond with the glass and fix the actual damage, your windshield will be just as vulnerable to any impact while you are driving then it would be if you did not fill the crack at all. The crack may continue to grow and further weaken your windshield.

When you take it to a professional repair service, however, they use techniques that bind the glass and actually repair the damage.

Unless you have the proper tools and background, you should leave the repair of your cracked windshield to the professionals, as you may end up making the problem worse. Instead of using DIY methods, take your car to an auto glass repair company to discuss your options for having them fix the damage for you.
