A windshield is one of the most vital safety features of any vehicle. However, it is also vulnerable to damage, with a spider crack being one of the most common types. If you’ve noticed a spider crack on your windshield, you may be wondering: is it repairable, or should you replace the entire windshield?
This article will help you understand the causes of spider cracks in windshields, how to fix a spider crack in your windshield, and when replacement is necessary.
What Is a Spider Crack Windshield?
A spider crack in a windshield is a circular break in the glass with small cracks radiating outward, resembling a spider web. These cracks often occur due to sudden impact from debris, such as small rocks or gravel hitting the windshield while driving at high speeds.
Spider cracks can be small and barely noticeable at first, but they can expand over time, especially when exposed to temperature changes, vibrations, and stress. The size and severity of the crack play a significant role in determining whether it can be repaired or if a complete windshield replacement is necessary.
Causes of Spider Cracks in Windshield
Understanding the causes and the types of cracks in windshield cracks in can help you prevent future damage.
Some of the most common causes include:
- Road Debris: Small rocks and debris from the road can strike the windshield, causing a spider crack. This is one of the most frequent causes of windshield damage, especially for those who drive on highways or gravel roads.
- Temperature Fluctuations: Extreme changes in temperature can weaken the glass, making it more prone to cracking. For example, using hot water to defrost a frozen windshield can cause a sudden expansion, leading to cracks.
- Poor Windshield Quality: Low-quality glass is more susceptible to cracks and chips. If the windshield was made from substandard materials, it might be more fragile and prone to damage.
- Improper Installation: If a windshield isn’t installed correctly, it can be more vulnerable to damage from minor impacts. An improperly fitted windshield may have weak points that make it more likely to develop spider cracks.
- Structural Stress: Over time, a windshield may develop weak points due to the pressure exerted on it while driving, leading to cracks. Sudden braking, potholes, or rough terrain can contribute to stress-related cracks.
- Accidents and Collisions: Even minor accidents can put pressure on the windshield and create spider cracks. A slight fender bender can cause hidden damage that worsens over time.
Can a Spider Crack in Your Windshield Be Repaired?
If a spider crack on your windshield is small enough (typically under the size of a quarter), it can often be repaired instead of replaced.
However, several factors determine whether repair is possible:
- Size of the Crack: If the crack is smaller than a quarter, repair is usually an option. However, larger cracks often require replacement.
- Location: If the crack is in the driver’s line of sight, replacement may be a better choice for safety reasons. Even a repaired crack can slightly distort vision, which can be dangerous.
- Depth of the Crack: If the crack extends through multiple layers of glass, replacement is often necessary. A deep crack compromises the windshield’s integrity.
- Time Since Damage Occurred: The sooner a crack is repaired, the better. Delayed repairs can allow dirt and moisture to seep in, making the crack harder to fix. This is why it’s recommended to address windshield damage immediately.
How to Fix a Spider Crack in Your Windshield
If the damage is minor, you can take a few steps to protect windshield from cracks:
Clean the Area: Use a glass cleaner and a microfiber cloth to remove dust and debris from the crack. Ensure the area is completely dry before proceeding.
Use a Windshield Repair Kit: Many auto stores sell DIY windshield repair kits that contain resin to seal small cracks. These kits usually come with an applicator and curing resin.
Apply the Resin: Follow the instructions in the repair kit to inject the resin into the crack and cure it using UV light. This helps to reinforce the glass and prevent further spreading.
Smooth the Surface: Once the resin is cured, use a razor blade to remove any excess and ensure a smooth surface. This will help in restoring visibility and maintaining the windshield’s integrity.
Consider Professional Repair: If you’re unsure about the repair process, it’s always best to seek help from an auto glass professional. They have specialized equipment to ensure a stronger and more durable repair.
When Should You Replace Your Windshield?
While repairs are possible for minor cracks, certain situations require a full windshield replacement, if you are concerned about the new windshield cost, then calling a windshield repairing company will help you out:
- The crack is larger than a quarter.
- There are multiple cracks affecting visibility.
- The crack extends to the edges of the windshield.
- The damage compromises the structural integrity of the windshield.
- The windshield has sustained multiple chips or fractures, making repair impractical.
A damaged windshield can significantly affect the overall safety of a vehicle. If the glass is weakened, it may not provide adequate protection in case of an accident. Replacing a severely damaged windshield ensures optimal safety and structural integrity.
Preventing Spider Cracks in Your Windshield
To stop crack in windshield, consider the following precautions:
- Keep a Safe Distance: Avoid driving too closely behind large trucks or vehicles that may kick up road debris.
- Avoid Sudden Temperature Changes: Do not pour hot water on a frozen windshield, as this can cause cracks.
- Choose Quality Windshield Glass: Opt for high-quality glass that meets safety standards.
- Address Small Cracks Immediately: Repair small chips before they expand into spider cracks.
- Park in the Shade: Direct sunlight can increase the chances of existing cracks expanding.
- Use Caution on Rough Roads: Drive carefully on gravel roads and avoid potholes that could stress the windshield.
The Cost of Repairing or Replacing a Spider Crack Windshield
The cost of fixing a spider crack on a windshield depends on several factors:
- Size of the Crack: Smaller cracks are less expensive to fix, while larger ones may require full replacement.
- Location of the Damage: If the crack is in the driver’s direct view, a higher-quality repair or replacement may be necessary.
- Type of Vehicle: Luxury vehicles or cars with advanced windshield technology (like rain sensors or heating elements) can be more expensive to repair or replace.
- Professional vs. DIY Repair: DIY repair kits are affordable, but professional repair ensures better durability and clarity.
On average, windshield repairs for minor spider cracks can cost between $50 to $150, while full replacements can range from $200 to $500 or more, depending on the factors mentioned above.
