The length of the crack is longer than a dollar bill and it's deep enough to penetrate more than half of the windshield. In this case, replacing the windshield is the best solution. If you want to stay safe while driving, never settle for a repair when you need a complete glass replacement. Not all cases of windshield damage are as clear-cut as the two examples mentioned above.
Sometimes, less obvious cracks and chips can lead to a windshield replacement. As a general rule, if your car's front window has any cracks, it's time to replace it. Whether you choose to replace it immediately or wait a couple more months, the ultimate solution is to get rid of the old one. If your windshield is heavily cracked, then replacement is the only way to go.
But if there's a small chip or crack, modern technology can often repair it at a fraction of the cost of replacing the windshield. We strongly recommend that you take your car to an automotive glass service provider after any damage to the windshield. The technician will assess the type, location, size, and thickness of the stain or crack to determine if repair is possible. The purpose of repairing a chip or small crack is to restore the structural stability of the windshield or car glass, as well as to return its original visibility.
If any of these scenarios develop for your car's front window, call an automotive glass repair company right away. Some auto glass repair providers offer discounts if multiple chips or cracks are repaired at once. After properly trimming and cleaning, the technician applies a new adhesive agent, replaces the gasket, and carefully installs the new car glass. When there's only a small amount of damage present, car glass repair is much more likely to be successful.
Even if the crack or chip is relatively small, repairing the car glass could leave a slight mark and that could impair the driver's vision. However, each case should be evaluated individually, but as a general rule, if the damaged area is less than the size of a dollar, repairing a car glass is very likely to be an option. Replacement is almost always prescribed whenever the inner glass has been damaged, regardless of whether or not the damage reaches the outer layer of the glass. If repair or replacement isn't done properly and professionally, the car glass won't have adequate stability.
Let's take a look at some of the ways you can tell if car glass repair is an option or if you need to replace the windshield completely. Chips 2.5 centimeters or less in diameter and cracks that are less than 8 cm long are usually easy to fix, although automotive glass repair may be possible for chips up to 7.5 cm and cracks up to 14 inches.
