Should I Replace or Repair my Windshield?

During the lifetime of your vehicle, this question will arise. Whether it is better to repair that quarter-sized chip or crack, or replace the whole windshield? Many motorists worry if dime or quarter-sized chips in the middle of the windshield are serious? Normally, they do not compromise the windshield’s structural integrity. Cracks near the edges of the windshield: that is a different story.

Stress cracks form from the edges of the windshield and are caused by weaknesses/defects in the glass itself.  Coming out of the factory, the windshield glass is heated up and cooled down very rapidly to form the shape necessary for that windshield. There may be defects in the manufacturing process: improperly heating and cooling of the glass greatly reduces its durability. This is the number one cause for the windshield displaying stress cracks early on.

From the factory, the windshield is held in place by a strong adhesive. Turbulent wind pressure could trigger small pressure changes along the glass causing stress cracks. Another common cause for windshield stress cracks are changes in temperature. Extreme changes in temperature can cause the glass to crack, such as washing your car with cold water after it has been outside on a hot day.

These stress cracks normally start out small and expand along the length of the windshield. If caught early enough, most windshield repair companies can repair a crack up to three to four inches in length. The repair usually involves injecting industrial-grade resin into the chipped or damaged sections. After the resin bonds to the chips and cracks, it is polished to remove any visual imperfections in the windshield.   While windshield repair companies try their best to make everything look perfect, sometimes the damaged areas are left with blemishes.

The other alternative is replacing the windshield. Depending on the extent and position of the crack, a new windshield may be the better alternative. When looking at windshield replacements, the first thing to consider is using an OEM (Original Equipment Manufacturer) Windshield or a Non-OEM Windshield that is compatible with your car. The OEM Windshield will cost more but in most cases fit perfectly. Non-OEM Windshields should adequately fit your vehicle. With the right amount of sealant, it will work for your car at a fraction of the OEM cost.
