Step by Step: How Windshield Chip Repair Actually Works


Do you know one of the major insurance claims that happen in the country is auto insurance for windshield problems? That’s how many people are being attacked on the windshield. The chips and cracks in the windshield are constant problems that almost every vehicle has to get once in their lifetime. Though sometimes it costs hundreds of dollars for a repair, in most cases these are repairable.

But do you know what happens to your windshield while in the repair shop? How do we get off those chips and cracks from your windshield?

Read on to know all these in the guide.

Chip Examination

The first thing we do when you bring your car for windshield repair is the examination. There are different types of chips and cracks. Each of them varies in shape, size, and depth. We examine everything and decide what treatment your windshield needs.


The name says what it is. A crack is a single line from the impact point to anywhere on the glass. If a crack in the glass is out of the driver’s sight and less than 12 inches in length, it can be repaired. If the crack is in the driver’s line of sight, it can not be repaired because the crack could affect the view of the driver.


It is a type of chip that looks like a bullseye. This chip has a deep impact point in the center and a dark circle around it.

If the diameter of this chip is less than an inch it can be repaired if the crack had not contacted with dirt or debris. However, if the bullseye is in the driver’s field of view, it can not be repaired.


It is a chunk missing from the windshield glass. It can be repaired if it is not spread and affected the windshield’s plastic interlay section between the glass layers. Otherwise, you have to replace the windshield.


A star is created by a number of cracks oriented from a central point in the windshield. If this star crack is less than three inches in diameter, it can be repaired. Again, it should not be in the driver’s field of vision.

Windshield Repair

Once we verified the type of chip, its size, depth, and location and find that it can be repaired, the below process starts.

The windshield replacement process is different from company to company. Let’s look into the basic methods and steps followed.

Clean the windshield

The first step is to clean out the crack or chip. As we always mention, dirt and moisture are two main causes for cracks spreading. It will disturb the repair process too. The glass fragments in the crack also are removed. It is done by scrapping a sharp tool into the crack. Know that it is all handled by a trained professional so don’t try these at home.

If the chip has many fine cracks, we apply pressure to extend the cracks. It may sound controversial but this way the cracks will join up so the filler or resin will flow easily throughout the crack.

Create a vacuum

After the crack is prepared, the crack repair tool is used. It is filled with resin and connected to the windshield with suckers. It creates the vacuum beneath the seal.

Fill with resin

Now the resin is ready to fill the crack. The time to completely fill the crack depends on the type of resin and size of the crack.

Set the resin

Some types of resin need to be cured by sunlight. It makes them hard and strong. 

Pit fill

If you need a chip repair, not a crack, it means your glass missing a piece. It needs additional resin to fill the pit. Usually, we made a hole and then cover it with tape to hold it in place.

Cure the resin

After the pit is filled, now the crack can be cured either by direct sunlight or a UV lamp. 

Remove excess

The excessive resin will then be wiped off. We brush away the excess resin and return your car.
