Should You Replace or Repair a Cracked Windshield?

A cracked windshield may seem like a minor car safety issue, but it can actually be a serious risk to the occupants of your vehicle. Cracks in the windshield can spread quickly, and they weaken its structural integrity.

The decision to repair or replace a cracked windshield depends on several factors. The size of the crack is important, but it’s also necessary to consider its location and duration.

Replace or Repair a Cracked Windshield


Depending on the location, size, and nature of your windshield damage, the cost of either repair or replacement will vary. The type of vehicle also plays a role in this. For example, luxury cars and trucks often have windshields with additional features that can increase the cost of a windshield replacement. In addition, some insurers may offer windshield repairs at 100 percent with no deductible, especially if you have comprehensive coverage that covers damage caused by natural events, such as storms.

The first factor to consider is the size of your crack or chip. While it is difficult to fix a crack that is more than a few inches long, technicians can usually repair fractures that are smaller than a quarter. The longer a crack is, the more likely it is to need a full replacement.

It’s also important to note that even if a crack can be repaired, it is still recommended that you replace the glass when it is located within the driver’s line of sight. Driving with a damaged windshield can be dangerous, as it can block the driver’s view of the road and increase the risk of a collision.

Additionally, any crack or chip that extends from the outer layer of the glass into the inner one can cause the windshield to discolor over time. This is due to exposure to heat and moisture, which can damage the plastic layer in the center of the windshield. Removing the cracked windshield as soon as possible and replacing it if the crack or chip reaches this point is important.

If you decide to repair a windshield, make sure that the technician you work with is certified by your insurance provider to complete the work. It is also a good idea to use clear tape to cover the crack or chip, which will help keep moisture and dirt out of the crack until it can be fixed. This will also prevent the crack from growing or spreading while it’s in place. It is also a good idea to park your car in a covered area and away from direct sunlight.


A cracked windshield is not just a nuisance but can be dangerous for the driver and passengers. It can obscure the driver’s view of the road and may also impair airbag deployment if it is on the front passenger side. A cracked windshield is a safety hazard and should be replaced immediately if possible.

The location of the crack is a significant factor in whether it can be repaired or not. Windshields are usually made of laminated glass, consisting of two glass layers fused with a plastic layer in between. This sandwiched design is designed to prevent the glass from shattering into granular pieces when it breaks, and it is also designed to hold together in case of an impact. If a crack starts at the edge of the windshield, there is a good chance that it will not be able to be repaired. This is because the glass will not be able to provide the necessary structural support in the event of an accident.

Another issue with cracks starting at the edge of the windshield is that they tend to spread quickly, which will significantly reduce the strength of your windshield. This can lead to the windshield completely shattering and endangering your life and those of your passengers. In addition, cracks at the edge of the windshield often obstruct the driver’s line of vision. This can be a serious safety risk and is likely to result in a failed car inspection.

If your windshield is starting to develop multiple cracks at the edge, it’s time for a replacement. Ignoring the damage can lead to a much bigger crack that will require more extensive repairs and potentially cost more than a full replacement. This is why it’s important to remember safety concerns and get the job done right the first time.


As long as your cracked windshield falls under comprehensive coverage, meaning that it isn’t related to an at-fault accident, you’ll likely be able to get it repaired without any issues. Even better, a claim for a broken windshield is unlikely to affect your premiums in the way that an at-fault insurance claim might.

It’s also important to note that not having your cracked windshield repaired isn’t worth trying to save a few dollars. Delaying the repair can make it much more costly and potentially lead to further damage. Moreover, driving with a cracked windshield is illegal and can result in a fine for the driver.

A good rule of thumb is that if a crack or chip is smaller than the size of a quarter, it can usually be repaired by an auto glass specialist. However, the exact method used will depend on the severity of the crack or chip and its location within the vehicle window.

Generally, a crack that spreads out from the center of the windshield and reaches the edge will need to be replaced, as this type of damage is more serious and compromises the structural integrity of the glass. Also, cracks that spread due to sudden temperature changes or faulty installation typically require a replacement, as these types of cracks are more difficult to repair.

Cracks that don’t reach the edge of the windshield are more manageable and can often be repaired with fill-in material. Keeping the damaged area covered with clear tape is still a good idea to prevent the crack from spreading further and avoid using the defroster or air conditioner. In addition, drivers should try to avoid slamming the car door and staying in extremely hot or cold temperatures, as these can cause the glass to expand and contract, which may further damage it.

A damaged windshield can significantly impair a driver’s view and compromise the safety of the vehicle. It’s a crucial component of the vehicle and serves three key purposes: supports the body in case of a rollover, provides an anchor for airbags, and protects the driver from the sun’s harsh rays.


A cracked windshield can be a big safety hazard for you and your passengers. It is important to have any damage repaired as soon as possible. This will prevent the cracks and chips from spreading further. The repair process takes about 30 to 40 minutes and is performed by injecting a clear resin into the damaged area. The resin hardens to restore the integrity and smooth appearance of the glass. It is a quick and cost-effective solution to your car’s windshield problems.

The size and location of the crack or chip is also an important factor in deciding whether or not it can be repaired. A cracked windshield can be repaired if the damage is small and limited to the outer layer of the glass. If the damage is deeper than this, a replacement may be needed. A cracked windshield that is directly in the driver’s line of vision will usually need to be replaced. This is due to the fact that the windshield acts as a support in case of a rollover accident.

It is also a good idea to put a piece of clear tape on the windshield as soon as you notice any damage. This will help keep moisture from seeping into the crack and causing further damage. Moisture can be caused by sprinklers, rain, and even general atmospheric humidity. The tape will also protect the urethane adhesive used to bond the windshield to the vehicle.

In most cases, a cracked windshield will need to be replaced rather than repaired. This is because a broken windshield compromises the vehicle’s structural integrity, which can lead to further problems and safety issues. Additionally, the cracked windshield can obstruct the driver’s view of the road and make it difficult to see other vehicles, pedestrians, and road hazards.

It is a good idea to consult your insurance company to find out if they cover the cost of a new windshield and the best course of action for your situation. The decision to replace or repair a cracked windshield should be made quickly and with the help of a professional.
