Windshield repair kits are sold in auto parts stores and online, promising an easy fix for chips and cracks. While these kits can be useful in some situations, they’re not always the best solution. Here’s what you should know before you decide to tackle a repair yourself.
How Windshield Repair Kits Work
Most kits include a resin compound, an injector tool, curing strips, and sometimes a UV light. The process involves cleaning the damaged area, applying resin to fill the chip or crack, and using pressure to remove air bubbles. Once the resin is in place, it’s cured and hardened to seal the damage.
According to NHTSA safety guidelines, proper bonding and curing are essential for maintaining windshield integrity.
When Kits Can Help
DIY kits can be effective for very small, shallow chips that haven’t spread. If the chip is smaller than a loonie and not in the driver’s line of sight, a kit may provide a temporary fix. However, even small repairs can be tricky without experience.
When Kits Fail
Repair kits have significant limitations. They often struggle to bond to deeper cracks or to damage that has spread beneath the surface. Incomplete filling can leave air pockets, leading to further cracking. Kits are also not designed to handle long cracks, edge cracks, or damage involving both layers of laminated glass.
Transport Canada emphasizes that repairs must fully restore the glass to avoid structural weaknesses. Learn more about these standards in their defect investigations resource.
Comparing DIY Kits to Professional Repair
Professional repairs use specialized vacuum systems and high-quality resins to remove debris and moisture completely. Technicians have the training to ensure the resin bonds properly and cures without leaving visible marks. Repairs performed by certified professionals are more durable and often come with a warranty.

Warranty and Insurance Implications
One drawback of DIY kits is that they typically don’t include any guarantee. If the repair fails, you could end up needing a full replacement, which costs significantly more. Insurance companies often cover professional repairs at no charge to you, but they may not reimburse DIY repairs or failed attempts.
Using a professional service helps ensure your insurance claim is processed smoothly and the repair is documented properly.
Before you decide to repair your windshield yourself, consider the safety, cost, and peace of mind that come with professional service.
