The Importance of a Windshield Replacement and Repair

Glass Doctor G12 Guarantee logo for auto glass

The windshield is part of a vehicle’s safety restraint system, or SRS, which also includes seatbelts and airbags. If any of these components are damaged, it compromises the effectiveness of the SRS. In addition to protecting you from road debris and the elements, your windshield’s main purpose is to keep you safe and inside the vehicle in a collision or rollover accident. When it is in good condition, a windshield promotes the architectural strength of your vehicle. It prevents the roof from collapsing and supports proper airbag deployment.

If your windshield has any damage, even a small chip, the glass could become a dangerous projectile in a collision. The force of the airbags may also prevent a damaged windshield from performing an essential duty - keeping passengers inside the vehicle.

As soon as you notice a chip or crack in your windshield, contact Glass Doctor of Kitchener-Waterloo.

Windshield Repair

Our team will always attempt to repair your auto glass before performing a windshield replacement. When a repair is a safe option, the techniques that our glass specialists use are as effective as a windshield replacement in regards to restoring your vehicle. You’ll also enjoy these added benefits:

  • Save money: Repairs cost less than a windshield replacement.
  • Eco-Friendly: The glass in windshield is often not recyclable. A repair keeps your windshield out of a landfill.
  • Save time: Glass specialists perform most repairs in under an hour.
  • Convenience: We will work around your schedule to perform a repair at a location that is convenient for you.
  • Maintain the G12Guarantee: If you have G12 Guarantee protection on a new windshield, a repair will not cancel the remaining term.
