Don't let cold weather trigger a major crack

The first cold nights this fall can create your first big headache of approaching winter. Dropping temperatures, especcially in cold climates, can turn tiny fissures and chips into extensive cracks along the length of your windshield.

Also, summer drivers often encounter pebbles and road debris kicked up by passing vehicles, especially in cone zones full of construction materials. Windshield imperfections caused by pebbles dramatically reduce visibility during early dusk hours—times when wildlife and school children are most active.

As a result, fall has become one of the best times to get your window professionally inspected. How can you prevent small problems from turning into an expensive windshield replacement?

"Replacing a windshield is not always the first option," said Peg Stroka, director of operations at the National Windshield Repair Association. "The first question to ask should be "Can it be repaired safely and effectively?" "A damaged windshield can reduce visibility, contribute to accidents and increase severity of injuries. In case of an accident, a structurally sound windshield enables the passenger airbag to function properly and minimizes roof collapse.

"Cracks and chips collect contaminants—water, dirt, insects—that can make glass more difficult to repair," Stroka said. "Cover the damage right away with tape to keep contaminants out until you can get it to a certified windshield specialist."

Stroka offered the following safety tips:

Cold weather can expand cracks and lead to full windshield replacement. Get those chips and cracks fixed. Even a small chip can reduce the structural integrity of the windshield.
Check with your insurance company for no-cost repair. Because it's quick and relatively inexpensive, insurance companies often waive the deductible for windshield repair. Remember, a damaged windshield may impair vision.
Use certified specialists. They can help avoid mistakes and safety-related problems. Technicians certified by the National Windshield Repair Association (in conjunction with the National Glass Association) are trained to meet industry standards for repair.
Improper fitting and cheap materials can cause the windshield to blow out during an accident. Technicians must carefully clean all debris and trim away old molding from windshield frames to provide a snug fit.
Insist on high-quality adhesive materials, not all sealants are made equal. Experts recommend the use of high quality urethane sealers.
Request OEM-quality glass—the kind used by the automobile manufacturers. This meets the same safety standards and proper fit.

"A windshield is part of the structural integrity of your vehicle," Stroka said. "Once you have a chip or a crack, that damage can spread if it is not repaired."
