Can You Fix a Cracked Windshield Without Replacing It?

Windshield Replacement Fort Myers

You might be wondering if you need to replace your entire windshield when a rock leaves a small crack or chip. In some cases, windshield repairs are a viable alternative. This blog examines the conditions under which a damaged windshield can be repaired without replacing it, the methods that are used, and the ways to determine whether a repair will suffice.

Understanding Windshield Damage

Windshield damage types

Chips and cracks are the two most common types of windshield damage. Chips are areas of missing glass, whereas cracks are lines running through the glass. Chips include the bulls-eye type, star break, and combination break.

Chip Bulls-eye

A bullseye chip looks like a target with a dark center. If caught early, this type of damage can be repaired relatively easily.

Star Break

Star breaks are characterized by multiple cracks that radiate from the point of impact. This type of damage can be repaired but may require a complex process.

Combination break

Combination breaks combine the features of star and bulls-eye break chips. If the damage is not too severe, it can be repaired.

Causes of Windshield Chips and Cracks

Windshield damage can be caused by road debris, temperature fluctuations, accidents, and other factors. Understanding the cause will help you determine whether to repair or replace the windshield.

When to Repair vs. Replace a Windshield

Damage Size and Depth

In order to determine if the windshield can be repaired, it is important to consider both the size and depth. Chips smaller than a quarter, and cracks shorter than three inches can usually be repaired.

Small chips

Repairing small chips is often possible, particularly if the damage is shallow and does not block the driver’s vision.

Long cracks

Typically, windshields that have cracks larger than 3 inches will need to be replaced as they can compromise the structural integrity.

Location of the damage

Repairability is also affected by the location of the damages on the windshield. If the damage is in the line of vision of the driver or at the edge of the windshield, it may be necessary to replace the glass.


It is important to repair damage within the driver’s line of vision, as minor distortions can impair vision.

Edges of the Windshield

The structural integrity of the windshield is often compromised by cracks at the edge.

Windshield Repair Techniques

Resin Injection

The resin injection method is commonly used to repair cracks and chips. Injecting clear resin in the damaged area is followed by curing and polishing.

Step-by-Step Resin Injection

  1. Cleaning: Remove all debris and moisture from the damaged area.
  2. Injecting resin: A special epoxy resin is injected directly into the crack or chip.
  3. Curing: The resin is dried using ultraviolet light.
  4. Polishing: To restore clarity, the repaired area is polished.

Windshield Repair

Minor repairs can also be done by patching the windshield. To prevent the crack from spreading, a clear adhesive patch is placed on the damaged area.

Applying Patches

  1. Clean the area. Make sure the windshield is dry and clean.
  2. Applying the Patch: Place the adhesive over the crack.
  3. Smoothing out: Smooth any bubbles for a snug fit.

Avoiding Windshield damage

Avoiding Road Hazards

Avoiding road hazards like loose gravel, construction areas, and large trucks which can kick up debris is the best way to avoid windshield damage.

Safe Driver Practices

  •  Keep a safe distance between you and other vehicles.
  • Avoid driving behind big trucks.
  • Use caution in construction zones.

Temperature Control

Existing windshield cracks can worsen in extreme temperatures. Controlling the temperature of your vehicle’s interior can prevent further damage.

Avoiding Rapid Temperature Changes

  • When the weather is hot, use windshield shades.
  • Do not use hot water to defrost your windshield during winter.
  • It is important to repair your car promptly.

How to prevent crack spread

It is important to repair windshield cracks and chips as soon as possible. This will prevent the damage from spreading and ultimately compromise structural integrity.

Early Damage Repair

Over time, small chips and cracks may grow larger and become more expensive to repair.

Maintaining Safety

Damaged windshields can reduce your visibility and the safety of your car. Repairing your windshield promptly will ensure that it remains functional and intact.

Structural Integrity

The windshield is a structural component of your car, and it’s especially important during an accident that results in a rollover. It is important to keep it in good shape for your own safety.


You can often fix a damaged windshield without having to replace it, as long as the damage is not severe and does not affect critical areas. You can maintain your windshield by making informed decisions if you know the different types of damage and how to repair them.
