So, you were driving home from work when a semi truck passed you, kicking a rock up straight into your windshield in the process. The rest of the way home, you watched in unease as the small chip from the rock impact slowly but surely spread into a rather noticeable crack. You know you need to have your windshield repaired as soon as possible, but you're also wondering what you can do in the meantime to prevent the crack from spreading to the point of disrepair.
Cover the Crack With Clear Tape
You'll want to avoid driving your car until you can have it fixed, if at all possible. If this isn't possible, you may be able to minimize spreading by placing a piece of tape over the crack--both on the inside and outside of the glass. Just make sure that the piece of tape you use is transparent and that it's not obstructing your vision while driving. Even if you don't plan on driving the car until the glass is repaired, taping over the damage can prevent unwanted dirt and debris from getting into the crack.
Park in the Shade, If Possible
Exposure to extreme temperatures or fluctuating temperatures can cause your windshield crack to spread rapidly, so try to keep your car parked out of the sun until you can have your windshield repaired, if at all possible. Take advantage of having the convenience of parking in a garage at your home, or a parking garage near your work. If direct shelter for your car isn't available, try to at least park underneath a tree or another form of shade.
Have a Repair Specialist Come to You
Finally, understand that many auto glass repair companies these days offer a mobile repair service, which enables them to come directly to you. This can be a great option not only for convenience sake, but for saving you from having to drive your car to the auto glass repair shop and risk the crack getting any bigger. You might have to pay a bit more for mobile service, but many will agree that it's worth it. And if you have insurance coverage for your auto glass repair, your insurance company should pick up the additional expense, anyway.
Dealing with a windshield crack can be a hassle, but by following a few simple steps, you can avoid letting the damage get any worse.
