What to Do When Your Windshield Cracks Cracked or chipped your windshield? Take a look at how it could've happened, and what you can do about it. by Team Onlia On The Road Nov 13, 2019 4 min read SHARE You’re driving along the highway, and notice a speck on your windshield. You turn on your wipers, but it doesn’t budge. Could it be a crack? Upon reaching your destination, you get out to inspect it – and sure enough, it is. It may not seem like a big deal at first, but crack in your windshield isn’t something to be ignored; it’s dangerous since it compromises the overall structure of your car, small cracks can spread into larger ones, and it can actually get you a windshield obstructed ticket in Ontario. What causes your windshield to crack? Windshield cracks can be caused by a number of things. One of the most common – and noticeable ways – is debris from vehicles in front of you like, large trucks, or from a hailstorm. If you can’t think of an obvious reason for the crack, it may have been caused by: Poor installation: Sometimes a windshield isn’t properly installed, and the resulting vibrations can cause cracks. Temperature fluctuations: Did the temperature plummet really quickly? Did you heat up your car or use a defroster to warm things up? This can cause the glass to expand unevenly, leading to cracks. Wind gusts: The pressure of driving against heavy winds could’ve caused your glass to crack. Glass defects: Sometimes, the windshield is just no good. If you take your car to a glass expert, they’ll be able to identify this. They’ll also be in the know about any windshield recalls. Do you need a repair or replacement? Whether you need a repair or a replacement all depends on the crack itself; its location and the type of damage will dictate whether it can be repaired, or if your entire windshield will need to be replaced. Location Your windshield has a section called the Driver’s Primary Viewing Area (DVPA). As the name implies, this section is critical to giving you (the driver) an unobstructed view of the road. If your crack is in this section and has a diameter larger than one inch you’ll likely need to replace your windshield; even a talented technician may be unable to prevent distortion while repairing this part of your windshield.

However, we recommend visiting a professional – saving a few dollars isn’t worth compromising your safety. Even self-proclaimed car DIY enthusiasts say that fixing a windshield is one task they leave to the pros. Professionals have years of experience and the special equipment to get the job done right. Talk to your insurance provider The cost of a windshield repair or replacement can vary depending on the car, the city, and special features – like condensation sensors. A windshield replacement can cost anywhere from $185 to $1,000 when you add in labour costs. According to a recent report, the average driver said they paid around $214. That said, be sure to chat with your insurance provider, since your policy might cover windshield repair. For instance, Onlia policyholders have repairs fully covered and a deductible is only charged if an entire windshield replacement is required. A few steps drivers can take to prevent windshield cracks are keeping their space from other cars (especially on the highway), driving at a moderate speed, avoiding gravel, and parking in the shade. Even if you take precautions, cracks do happen – and when they do, it's important to deal with them as soon as possible.
