If you notice a small crack sprawling across your windshield like a spider web, you are looking at spider cracking. Although these spidery cracks may appear momentarily harmless, they indicate serious structural issues.

How to Identify A Spider Crack in A Windshield?

A spider crack windshield originates from a small chip in the auto glass that begins to expand across the windshield. The cracks resemble the threads of a spider web, earning them the spider crack moniker. These fissures can be located on the outer and inner panes of glass. They are often spotted on the windshield edges but can form anywhere.

Spider cracks form around an impact point, often caused by a small rock or piece of debris on the road. Although it may be minuscule—almost unnoticeable—the impact point can form long cracks that become safety threats if left unchecked.

What Causes Spider Cracks in A Windshield?

Extreme fluctuations in temperature can cause spider cracks. Sudden shifts in temperature extremes can weaken the glass and cause it to be more susceptible to spider cracking.

There are many other potential causes for a spider crack windshield:

  • Rocks and other road debris
  • Driving in harsh weather conditions (cold rain, ice, hail, storms, etc.)
  • Collisions
  • A poorly installed or maintained windshield

How Dangerous Are Spider Cracks in A Windshield?

Spider cracks are extremely dangerous! Any form of windshield cracking should be treated as a safety threat that must be dealt with immediately.

Although spider cracking may initially seem minor, it indicates underlying structural issues in the windshield. If true, spider cracking will be seen primarily along the windshield’s edges.

Depending on their location, spider cracks can also impair the driver’s vision. A spider crack windshield is much more likely to shatter in a collision.

The longer spider cracking is left to enlarge unchecked, the more costly the replacement will be and the more danger it will pose.

Should I Repair or Replace my Windshield with A Spider Crack?

Although repairs can be made to a spider crack windshield, this is only a temporary fix. Spider cracks can spread over time, meaning that eventually, a windshield replacement is the only viable solution.

In the meantime, you may wonder how to stop a windshield crack from spreading. Keeping the windshield clear of dirt or debris and using gentle cleaning methods can help slow the spread of spider cracking.

To prevent spider cracks from expanding, make sure to avoid exposing the windshield to extreme temperatures as much as possible:

  • Avoid parking in the sun.
  • Don’t blast the AC immediately after starting the car.
  • Point fans away from the windshield.

Sadly, these are only temporary fixes. Once you discover spider cracking, you should immediately consult a professional. You can temporarily treat these tiny fissures with an adhesive, but they still indicate a more serious structural issue, signaling that it’s time to consider replacing the windshield.

Ask Yourself the Following Questions About Windshield Replacements

How Big is the Crack?

You can more easily repair cracks less than 3–6 inches long. However, these cracks will not remain the same size for long and will eventually expand. Develop a plan to counteract this expansion.

How Deep is the Crack?

If the crack has penetrated the inner and outer layers of the glass, you will need a replacement. This penetration through the laminate layers of the auto glass increases the risk of the windshield shattering.

Where is the Crack Located?

If the crack is on the outer edge of the windshield, it likely compromises the structural integrity. In this case, do not attempt to repair the windshield yourself—a professional must handle it. If the crack obstructs the driver’s visibility, you must replace the windshield.

Does Car Insurance Cover Spider Cracks?

Wondering, ‘Does car insurance cover a cracked windshield?’ The answer is generally yes, as long as the damage is from a covered incident.

Be sure to familiarize yourself with the type of coverage you have and carefully assess the damage’s extent. Understanding your policy’s specifics, such as deductibles and coverage limits, is crucial when dealing with spider cracks. This knowledge will help you determine whether your windshield repair or replacement is covered and to what extent, ensuring you can manage the situation effectively without unexpected out-of-pocket costs.
