Windshield cracks can be a nuisance for any driver, but many drivers fail to consider the safety risks of windshield cracks.
Not only can cracks impair driver vision, but they can also weaken the bond of the windshield, depending on the crack’s location.
Unfortunately, windshield cracks are far too common in Northeast Pennsylvania between the area’s rough roads and the storms it experiences throughout the year.
The good news is that windshield cracks can be repaired quickly and for very little cost (depending on the size and location of the crack). But drivers who allow windshield cracks to spread can be in for a rude awakening if the crack becomes severe enough to require replacement.
Learn how to stop a windshield crack from spreading and what steps to take to fix a windshield so that you can save money.
Common Causes of Windshield Cracks
First, it’s important to determine the type and cause of windshield crack to determine your options moving forward. Depending on the cause, you may be covered under your insurance, even if you don’t have comprehensive coverage.
Some common causes of windshield chips and cracks include:
- Flying Debris or Road Hazards: Traveling down gravel roads, behind commercial vehicles, or beneath falling tree limbs can all lead to windshield damage that can be substantial in nature.
- Temperature Fluctuations: Common freeze-thaw cycles experienced throughout the winter months can lead to stress cracks and a loosening of the bonding agent holding the windshield in place.
- Accidents and Collisions: Even minor fender-benders can cause windshield cracks, especially if the impact hits a vulnerable point on the glass.
- Poor Installation: A poorly installed windshield may not be adequately supported in the frame. When the car moves or flexes, an improperly installed windshield is more susceptible to cracking from internal stress.
- Hail or Severe Weather: Hail, heavy snowfall, and extreme weather can damage windshields, especially if the impact is forceful or repetitive.
Types of Windshield Cracks
Next, we need to determine the type of windshield crack to determine if it can be repaired and with what measures. For example, small chips can be repaired using DIY repair kits, while edge cracks and stress cracks almost always require windshield replacement.
- Chip: A small impaction on the surface level of the glass that can typically be repaired with a resin filler.
- Bullseye: Resembling a bullseye or target mark, this crack features a circular pattern around the impact point. Bullseye cracks are common and often repairable if treated early.
- Edge Crack: Starting within two inches of the edge of the windshield, edge cracks are more likely to spread and can compromise the overall stability of the glass. These often require a full replacement, especially if they damage the seal of the windshield glass.
- Stress Crack: Caused by extreme temperature changes, a stress crack typically starts without any impact point but spreads quickly. These cracks are more challenging to repair since they are often due to underlying weaknesses in the glass.
- Floater Crack: Starting in the middle of the windshield, floater cracks can grow quickly if left untreated. These are often caused by debris impact or internal stress within the glass.
4 Ways to Stop Windshield Cracks from Spreading
In many cases, windshield cracks and chips can be treated early to prevent further damage. Following are four steps to stop a windshield crack from spreading.
1. Act Quickly and Cover the Crack
Small cracks that don’t form near the edge of your windshield can often be treated with a special resin filler. However, it’s important to cover the crack to prevent moisture and debris from penetrating the crack and causing it to expand until it can be repaired.
First, attempt to clean the crack using a dry cloth to remove any moisture or debris.
Some options to cover the crack include applying clear tape or super glue that will seal the crack and block out any debris.
While these steps won’t prevent the crack from growing indefinitely, it can provide a short-term fix to stop immediate spreading.
2. Avoid Environmental Stresses that Can Worsen the Crack
Next, you’re going to want to avoid as many potential hazards that could spread the crack until you are able to get it fixed. Some tips include:
- Avoiding rough roads with potholes and gravel–PA’s roads are ranked the 11th worst in the country so watch out!
- Maintaining a safe distance behind other vehicles, especially commercial vehicles.
- Keeping the vehicle in a temperature-controlled garage to prevent freeze-thaw cycles.
- Using the defroster and A/C softly before ramping them up to full speed.
- Replacing any wipers that may be rubbing against the glass and causing friction
3. Use a Windshield Repair Kit (If Applicable)
While we’ve written extensively about windshield repair kits and caution most drivers against them, there are certain cases where a kit could be sufficient for repair. For example, small, surface-level cracks can usually be repaired with an over-the-counter product. However, it’s always ideal to get your windshield inspected to determine the best course of action so you can avoid more expensive repairs.
4. Contact a Windshield Repair Shop for Available Solutions
Perhaps the first or final step in stopping a windshield crack from spreading is taking it to a windshield repair shop. We recommend a specialty auto glass shop as they usually work with your insurance and can provide essential services, such as calibration on a new windshield.
Most auto glass shops, like Northeast Auto Glass, offer in-shop or mobile windshield repair–both of which offer the same level of service quality. Mobile repair is available for most forms of windshield crack or chip repair and can be safer and more convenient, depending on where you live.
When to Replace Your Windshield
In some cases, windshield replacement may be necessary for the safety of the driver and vehicle. Here are some things we use to determine whether or not a windshield needs to be replaced:
- Presence of Multiple Cracks: Numerous cracks compromise overall stability and are harder to repair effectively. In most cases, this will necessitate complete replacement.
- Deep Penetrating Cracks: Cracks that penetrate beyond the top layer of glass cannot be repaired and require replacement.
- Location of the Crack: Cracks near the edge of the windshield are more likely to spread and impact the frame, requiring replacement.

FAQs
Is it safe to use super glue on a cracked windshield?
Super glue can be a temporary measure for small cracks, but it should not be used as a permanent fix. It may not withstand temperature changes or road vibrations as well as professional repair resin.
Can I drive with a cracked windshield?
Pennsylvania does not allow for any cracks or chips on the center of the driver’s side of the windshield. While some chips and cracks may technically be legal, it can be unsafe and cause you to fail inspection.
How long can I wait before repairing a windshield crack?
Waiting too long can worsen the crack and increase repair costs. It’s generally advised to seek repair as soon as possible to prevent spreading and maintain safety.
