Can Auto Glass Be Repaired If It’s Cracked?

A cracked windshield doesn’t always mean you need to replace the entire windshield. 

In many cases, small chips or cracks can be repaired using modern technology, such as resin injection and UV curing. By using these methods, repairs can be made safely and without leaving any spots. 

However, the size, depth, and location of the crack are also factors in determining whether the damage can be repaired or if replacement is the only option. If you understand the types and can differentiate between them, then you can make an informed decision for your car.

In this content, I’ll clarify all aspects from a different angle, so you can make a decision quickly and avoid unusual expenses. 

Let’s get started. 

When Can Cracked Auto Glass Be Repaired?

Having cracks on your vehicle’s windshield doesn’t mean signing up for a replacement. However, there is a 78% chance of replacement, but repair can also be done. But it must meet several conditions. 

So, what if they don’t work then?

Then, there will be no repair shop worth trusting. Here’s what really matters:

Size and Length Limits

Sometimes, we don’t take small cracks seriously. If the size of cracks extends beyond their regular size, then it’s hard to manage. 

Actually, there is no ideal size that indicates it is not repairable. However, experts recommend that if the size of the crack exceeds 6 inches, it can’t be repaired and must be replaced. The structural integrity of glass can be damaged if the chip is too deep. 

A small chip can be easily patched, but if it spreads, it becomes difficult to replace, and neither DIY nor a technician can repair it. That’s simple.

Location of the Crack

The location of cracks is similarly essential as the length of cracks on the windshield. 

No matter how well it’s repaired, there will still be a spot on the glass. However, this spot may not be immediately visible unless you take a close look. Therefore, if the crack is not occurring in a random area, such as one that is visible to the driver, then replacement is a safe option.

Usually, the crack spreads quickly if it happens on the edge of the glass. If you repair it, then it cannot be run for a long time.

If the crack’s location is out of the driver’s sight and not on the edge of the glass, then those can be managed.

Depth of Damage

A windshield is made of three different layers, including glass and plastic. A plastic layer remains between two glass plates. 

If the damage occurred on the top layer, then you don’t have to invest in windshield replacement. On the contrary, if a crack occurred in the deep portion, then replacement would be a safer option. 

When Replacement is Necessary Instead of Repair?

A simple decision may save thousands of dollars. In my opinion, it’s essential to know when replacement is a safe option and when repairing the windshield is sufficient. 

So, how can you make this decision, as you are not an expert? Let’s see several criteria that will help you make a better decision:

Severe or Long Cracks

If the crack is severe, long, or deep, then repair may not be the best choice. So, how long or deep, and how to measure? 

Just check with a measurement tool to see if the crack is indeed 6 inches long. If that were to happen, then investing in repairing your glass could be a waste of money. 

A long or deep crack not only damages the structural integrity but also raises safety issues. And, you should consider the safety of saving a few bucks. If you’re trying to repair it, the ultimate result is to replace the windshield. 

Keep in mind that the windshield is not just glass; it supports your airbags and keeps the roof safe from collapsing. 

Multiple Cracks Spreading Across the Glass

Sometimes, less than 6 inches can be considered for several months, but if your windshield has more than one crack, it could compromise the integrity of your windshield.

You can repair your windshield if it has isolated damage. When you have to deal with multiple networks of cracks, then replacement is the only option. 

These multiple cracks gradually weaken the entire glass’s strength. Moreover, it is a great safety issue. If you don’t replace it, then you should not drive on a busy road. This may lead to a penalty from the police. 

Safety Risks of Ignoring Replacement

No doubt, if you ignore the badly cracked windshield, it can be more dangerous than you can imagine.

A weak windshield not only supports the air bag system but also indicates a negative impact on the glass. Thus, it loses overall protection in the event of an accident. 

Another aspect to consider is ‘Obstructed visibility’. Cracks that spread across your field of vision make it harder to see if any road hazards have been on the road.

In some states, it is a punishable offense for any driver to operate a car with large cracks that obstruct the driver’s view.

Repair vs Replacement: Cost and Insurance Considerations

Repair or replacement of a windshield is closely associated with the cost and insurance. Generally, the cost of repair is comparatively lower than the replacement cost. Now, let’s see some criteria based on it:

Average Cost of Repair vs Replacement

You will need to spend $50-$150 for repairs, which depends on the size and number of large chips or cracks. For windshield replacement, the cost ranges from $200 to $500. Besides, the costs may exceed $1000+ due to having a smart sensor. At Save on auto glass windshield replacement cost, starting from $99

So, why is it so important? 

Because you can save several hundred dollars if the chip is small and easily repairable, however, if the damage is too severe, replacement may be the only option, even if the costs are higher than the repair costs.

Insurance Coverage for Cracked Glass

Here’s an interesting fact that comes to every car owner’s mind. Yes, it’s all about insurance coverage.

Several insurance companies bear the entire repair costs because this is so affordable compared to the replacement. 

Several states provide ‘zero deductible’ glass coverage, which means you don’t have to pay a single penny for the glass repair. 

However, the replacement depends on the insurance policy, and typically, you must pay the deductible out of pocket. Later on, you can also contact them.

Deductibles and Filing a Claim

If your deductible is more than the cost of repairing, then there is no point in the ultimate coverage. Usually, the repair cost would be lower, and it may even be free if you have insurance coverage. 

On the other hand, replacement is too costly; however, insurance may cover the expense. However, you must ensure that the deductible facilities are not lost. 

Repair Techniques and Technology

A windshield repair doesn’t mean only to fill the chip. This process is modern and technology-based. In the modern auto glass repair process, several specialized tools are used, which provide accurate results and enhanced visibility. 

Resin injection method

This is the first and foremost step for windshield repair. First of all, technicians clean the damaged area by taking apart the loose pieces of glass. Then, a sticky, crystal-like substance called resin has been added. This subject has been injected into the damaged or cracked area. These substances fill the gap and restore the original strength of glass quickly. 

The purpose of using resin is to fill the cracks and prevent them from spreading, thereby restoring the structural integrity. Besides, resin works so accurately that it is almost invisible to the crack. As a result, vehicle protection and overall development were improved compared to the previous conditions. 

UV curing process

After the completion of the resin injection, it’s necessary to strengthen or cure. In this step, UV light is used. The technician projects light on the affected place using a UV light. It creates a chemical reaction inside the resin, and within a few minutes, it becomes hard. 

Then the repaired place will be polished to become soft and transparent. As a result, it provides a sustainable and fresh repair that lasts even in normal driving conditions. 

Final word

Overall, the crack repairs normally if the crack is small in length or a small chip and doesn’t remain in the driver’s eye sight. However, if the crack is deep, long or spreads rapidly then it’s better to change the windshield. It is safe and dependable. 

Steps taken over time not only ensure structural stability but also maintain cleanliness, visibility, and road safety. With advanced repair technology and insurance advancements, taking prompt steps can protect you from potential financial risk. And most importantly, your car will remain in a high state.
