Driving down the road and hearing a sudden impact on the windshield can be an unsettling experience. Even if a crack or imperfection caused by debris tossed up from another driver's wheel doesn't require immediate attention, it is the beginning of the end for a windshield. Fortunately, auto glass replacement services are easy to access in most locations and frequently include a degree of portability.

When do you need to replace the windshield? 

Small windshield imperfections, such as shallow chips, generally do not require repair or windshield replacement. Larger cracks, such as those longer than a piece of paper money and chips that penetrate halfway or more through the windshield, need an assessment by a professional to ensure you can continue to drive safely, according to Allstate. Other points of concern are cracks that reach the outer edge of the windshield, even if they are shorter. Cracks or chips with spidering are also likely to spread further, making rapid consultation important. 

Repairs are possible for some windshield cracks or chips, so ensure you get an assessment to find out if a full change is necessary or if windshield repair is an option. In the repair process, a professional layers adhesive into an imperfection before smoothing and allowing for drying time. After the adhesive has hardened, final cleaning and smoothing are completed, and the windshield should continue to function well unless other impacts occur.

Dangers of a cracked windshield

Windshield damage is distracting at best, with many cracks or chips obstructing the driver's view or leading to unnecessary and disorienting glare. However, the danger extends far beyond visibility. A cracked windshield loses its structural integrity, and depending on the severity of the cracks, it could shatter with minimal impact and injure car occupants. It could also eventually fail entirely while you are driving and completely impede visibility due to massive spidering or shattering and falling out into the car or the road. 

Windshield replacement

Replacing a windshield is a fairly easy process. Some car dealerships with service centers change windshields and many specialty shops focus solely on replacing auto glass. Based on your needs, they often have an adjacent service that can provide remote installation if your glass is completely shattered on the road or your car can no longer operate safely. Services of an auto glass repair business can be covered by insurance policies, but standard windshield replacement is generally an add-on. If you have questions about eligibility, reach out to your insurance provider for clarification.

On the day of a replacement, be prepared to wait for service and to allow for drying time for the adhesive holding the windshield in place. When your car is ready to leave, the shop provides full instructions for care over the next few hours.
