Common Causes of Auto Glass Damage and How to Prevent Them

Temperature Changes

Extreme temperature changes can cause stress on your auto glass, leading to cracks. In hot weather, the glass expands, while in cold weather, it contracts. Rapid shifts from hot to cold, or vice versa, can cause the glass to crack.

How to Prevent Temperature Change Damage

To prevent damage from temperature changes, avoid sudden shifts in temperature. For example, in winter, don't pour hot water on your windshield to defrost it. Instead, use an ice scraper or defrost setting on your car heater gradually. In summer, try to park in the shade or use a sunshade to keep your car cooler. Avoid blasting the air conditioning directly onto the hot windshield as well.

Accidents and Collisions

Accidents and collisions are significant causes of auto glass damage. Even minor fender benders can result in cracks or breaks in your windshield or windows.

How to Prevent Damage from Accidents and Collisions

While it's impossible to completely avoid accidents, you can reduce the risk by practicing safe driving habits. Always obey traffic laws, maintain a safe following distance, and stay alert to your surroundings. Additionally, ensure that your vehicle's safety features, such as airbags and seat belts, are in good working order.

Falling Objects

Falling objects, such as tree branches, construction debris, or even heavy snow and ice, can cause significant damage to your auto glass. Parking under trees or buildings with loose materials increases the risk of such damage.

How to Prevent Falling Object Damage

When parking your car, be mindful of your surroundings. Avoid parking under trees, especially during storms or windy conditions. If you must park near a construction site, try to find a spot that is not directly under scaffolding or areas where debris could fall. In winter, clear heavy snow and ice from your car and surrounding area to prevent it from falling onto your windshield.

Pressure Changes

Pressure changes, such as those caused by high winds or when driving at high speeds, can stress your auto glass. Sudden pressure changes can cause small cracks to expand or even shatter the glass.

How to Prevent Pressure Change Damage

To protect your auto glass from pressure changes, regularly check for and repair any small chips or cracks before they have a chance to grow. When driving at high speeds, especially on highways, ensure that your windows are properly closed and sealed to prevent wind pressure from affecting the glass.

How to Prevent Damage from DIY Repairs

Leave auto glass repairs to the professionals. While DIY kits are available, they often do not provide the same quality of repair as a trained technician. If you notice any chips or cracks in your auto glass, take your vehicle to a certified repair shop to ensure the damage is properly and safely fixed.
