When to Replace Your Windshield

Several factors can necessitate windshield replacement, including: - **Cracks and Chips**: If the damage is larger than a quarter or if it obstructs the driver's view. - **Stress Cracks**: These can occur due to temperature fluctuations. - **Delamination**: This happens when the layers of glass begin to separate.
