A Simple Guide to Glass Windshield Cracks

A cracked windshield looks unattractive, can compromise the vehicle’s structural integrity, and distract drivers.

Windshield cracks are a common problem vehicle owners encounter, and they can be dangerous. A cracked windshield looks unattractive, can compromise the vehicle’s structural integrity, and distract drivers. Some windshield cracks are more severe than others and demand immediate professional attention. Cracks in the windshield, if ignored, can spread over time, leading to more severe damages and expenses.

This post discusses all you need to learn about windshield cracks to help you make informed decisions.

Types of windshield cracks

Stress crack

Stress cracks are internal and usually triggered by sudden temperature changes. An old and aging windshield glass can also experience stress crack.

Edge crack

An edge crack is within two inches of the windshield’s edge. The length of an edge crack can vary from 10 to 12 inches. Replacement is the most feasible solution for windshields with an edge crack, and only an expert technician should perform the installation.

Bullseye crack

When a small object hits the glass, it results in a bullseye crack. It results in surface damage and is usually in a circle shape.

Star

A star-shaped break may appear when a sharp object or rock strikes the windshield, which chips away a piece of glass. These rock chips can escalate quickly into significant cracks so they require immediate repair. 

Combination

If there are multiple cracks and chips on the windshield surface, they are known as combination cracks. A combination crack is powerful and happens on both the top and bottom of the windshield. A professional can examine the damage, and seeking timely assistance for minor cracks can prevent replacement requirements.

Crack chips

Minute cracks sustained due to small cracks and pebbles are known as crack chips. These cracks are generally repairable by seeking professional help quickly. 

Floater crack

Floater cracks usually appear at the windshield’s center or two inches from its edge. They can vary in length and can spread quickly if not tended to immediately. A technician can suggest repair or replacement after assessing the width and depth of the cracks.
