Understanding the Types of Windshield Cracks
A cracked windshield can be a frustrating and potentially hazardous issue, especially if left unchecked. The first step in stopping a windshield from cracking further is to assess the damage and identify the cause. There are several types of windshield cracks, each with its unique characteristics and severity levels.
Minor cracks, also known as stress cracks, are usually caused by sudden temperature changes, road debris, or minor impacts. These cracks are typically hairline fractures that may not be immediately noticeable. On the other hand, major cracks, also known as rock chips or bullseye cracks, are more severe and often require immediate attention. These cracks can be caused by larger impacts, such as hitting a pothole or a rock on the road.
Inspecting the Windshield for Damage
When assessing the damage, it’s essential to inspect the windshield thoroughly for any signs of cracking or damage. Look for:
- Visible cracks or chips
- Stress lines or spiderwebbing
- Discoloration or haze
- Leaks or water damage
Using the Windshield Assessment Guide
To help you assess the damage, we’ve created a simple guide:
| Type of Damage | Description | Severity Level |
| — | — | — |
| Minor Crack | Hairline fracture, usually caused by sudden temperature changes or minor impacts | Low |
| Major Crack | Larger fracture, often caused by impacts or road debris | Medium to High |
| Stress Lines | Spiderwebbing or cracks caused by stress on the windshield | Medium |
| Discoloration | Haze or yellowing of the windshield due to age or exposure to sunlight | Low |
| Leaks | Water damage or leaks around the windshield | High |
Identifying the Cause of the Crack
Once you’ve assessed the damage, it’s essential to identify the cause of the crack. This will help you determine the best course of action to prevent further damage. Common causes of windshield cracks include:

- Manufacturing defects: In some cases, the windshield may be defective from the factory, leading to cracks and other issues.
It’s worth noting that windshield cracks can be classified into three main types:
Types of Windshield Cracks
- Bullseye cracks: These are circular cracks that form when a small object, such as a rock, hits the windshield.
- Rock chips: These are small cracks that form when a rock or other debris hits the windshield.
- Long cracks: These are linear cracks that can form due to a variety of factors, including temperature fluctuations and impact damage.
Each type of crack requires a different approach to repair, and understanding the type of crack you have will help you choose the most effective solution.
Assessing the Severity of the Crack
Before attempting to repair a windshield crack, it’s essential to assess its severity. A crack that is deep, long, or in a critical area of the windshield may require professional attention. In some cases, the crack may be too severe to repair, and a replacement windshield may be necessary.
Here are some factors to consider when assessing the severity of a windshield crack:
- Depth: A crack that is deeper than 1/8 inch may be difficult to repair.
- Length: A crack that is longer than 12 inches may be too extensive to repair.
- Location: Cracks in critical areas, such as the driver’s side or rearview mirror, may require professional attention.

Frequently Asked Questions
What is the main cause of a windshield cracking further?
A windshield can crack further due to various factors, including temperature fluctuations, road debris, and impact from other vehicles. The most common cause is thermal stress, which occurs when the glass expands and contracts with temperature changes. This stress can cause the crack to spread, especially if the windshield is already weakened by previous damage or age. Understanding the main cause of the cracking is essential to determining the best course of action to prevent further damage.
How does a windshield repair kit work to stop a crack from spreading?
A windshield repair kit typically includes a resin that is injected into the crack to fill it and prevent further spreading. The resin is designed to match the color and texture of the surrounding glass, making it nearly invisible. The kit usually includes a specialized tool to inject the resin and a hardening agent to cure it. When applied correctly, the resin fills the crack, preventing it from spreading and potentially saving the windshield from needing replacement. However, it’s essential to note that not all cracks can be repaired, and a professional assessment is usually necessary to determine the best course of action.
Why should I repair a windshield crack instead of replacing it?
Repairing a windshield crack is generally cheaper and faster than replacing the entire windshield. It also preserves the original glass and eliminates the need for a new windshield, which can be a costly and time-consuming process. Additionally, repairing a crack can prevent further damage and potentially save the windshield from needing replacement altogether. However, it’s crucial to repair the crack as soon as possible to prevent it from spreading and becoming more difficult and expensive to repair. Regular inspections and prompt repairs can help extend the life of the windshield and prevent costly replacements.
How do I start to repair a windshield crack with a DIY kit?
To start repairing a windshield crack with a DIY kit, first, clean the area around the crack to ensure the resin adheres properly. Then, use the specialized tool to inject the resin into the crack, following the manufacturer’s instructions. Apply the hardening agent to cure the resin, and let it dry according to the instructions. It’s essential to follow the manufacturer’s guidelines and take necessary safety precautions, such as wearing gloves and working in a well-ventilated area. If the crack is deep or large, it may be best to consult a professional for assistance.
What if the crack is too large to repair with a DIY kit?
If the crack is too large to repair with a DIY kit, it’s best to consult a professional windshield repair technician. They will assess the damage and determine the best course of action, which may involve replacing the windshield. A professional technician will have the necessary tools and expertise to repair or replace the windshield safely and efficiently. In some cases, a professional may be able to repair a larger crack using advanced techniques and equipment. However, if the crack is too large or in a critical area, such as the driver’s side, it may be necessary to replace the windshield for safety reasons.
Which is better, repairing or replacing a windshield?
The decision to repair or replace a windshield depends on the size and location of the crack, as well as the age and condition of the windshield. Repairing a small to medium-sized crack is often the most cost-effective and efficient solution. However, if the crack is large or in a critical area, replacing the windshield may be the better option for safety reasons. Additionally, if the windshield is old or damaged, it may be more cost-effective to replace it entirely. A professional assessment is usually necessary to determine the best course of action.
How much does it cost to repair a windshield crack?
The cost to repair a windshield crack can vary depending on the size and location of the crack, as well as the type of resin and equipment used. On average, a DIY kit can cost between $20 to $50, while a professional repair can cost between $50 to $200. However, if the crack is large or requires specialized equipment, the cost can range from $200 to $500 or more. In some cases, replacing the windshield may be more cost-effective, especially if the crack is large or in a critical area.
What are some common mistakes to avoid when repairing a windshield crack?
Some common mistakes to avoid when repairing a windshield crack include using the wrong type of resin, applying too much or too little resin, and not allowing the resin to dry properly. Additionally, using a DIY kit on a crack that is too large or in a critical area can be dangerous and may not be effective. It’s essential to follow the manufacturer’s instructions and take necessary safety precautions when repairing a windshield crack. If unsure, it’s always best to consult a professional for assistance.
Can I use a windshield repair kit on a windshield that has already been repaired?
It’s generally not recommended to use a windshield repair kit on a windshield that has already been repaired. This can cause the resin to interfere with the existing repair, leading to further damage or cracking. If the windshield has already been repaired, it’s best to consult a professional to assess the damage and determine the best course of action. In some cases, a professional may be able to repair the windshield again, but it’s essential to ensure that the existing repair is stable and not causing further damage.
