A rock chip on the interstate starts as a mark you can cover with a fingernail. Left alone, heat, cold and road shock can run it into a crack across the glass, and a cracked windshield usually has to come out. Windshield repair stops that from happening. Impex Auto Glass repairs chips and short cracks at our drive-in shop in Greensboro and by mobile windshield repair across North and South Carolina. Timely repair restores strength, improves visibility and helps prevent a costly replacement.
- Chips and short cracks filled before they spread
- Often saves the original windshield
- Insurers often waive the deductible for repair

What Can Be Repaired
A repair may be possible when the chip or crack is small, shallow and away from the edges of the glass. Three things decide it: how big the damage is, where it sits and how deep it goes. Send a photo with your quote request and we will tell you whether you are looking at a repair or a new windshield.
Chips Smaller Than a Quarter (Rule of Thumb)
Small chips, smaller than a quarter, can usually be repaired. That covers most of what a stone leaves behind: a bullseye (a round crater), a star break (short legs running out from the impact point) or a combination of the two. The quarter is a rule of thumb rather than a hard limit; the repair industry’s standard is wider, but a chip that size is the clearest case for repair.
Short Cracks Away From the Edge
Short cracks that are not in the driver’s line of sight can usually be repaired too. The repair standard (ROLAGS, the Repair of Laminated Automotive Glass Standard) calls a crack of six inches or less a short crack, and lists single line cracks up to 14 inches as repairable. In practice, the closer a crack is to the edge, the more likely it is to keep running, and a crack that reaches the edge is usually a replacement.
When Repair Is Not Safe
- The damage is large or deep, or it has gone through to the inside layer of glass.
- A crack reaches the edge of the windshield.
- The chip or crack sits in the driver’s direct line of sight, where even a good repair can leave a faint mark that distorts the view.
- The damage is in front of the camera or sensors at the top of the glass.
In those cases a full replacement is the safer option, because the windshield’s strength and clarity are part of how the car protects you. Our windshield replacement page explains that job, including camera calibration and drive-away time.
How Chip Repair Works
A windshield is laminated: two layers of glass bonded to a clear plastic layer in between. A stone usually damages only the outer layer, which is why a chip can be saved. The technician cleans the break, draws the air out of it and fills it with a clear repair resin, then cures the resin and polishes the surface smooth. The filled break stops collecting dirt and moisture, the glass regains its strength around the impact point, and the damage is far less visible than before.
Our certified specialists handle windshield crack repair as well as chips, and the work does not involve removing the glass, so the seal around the windshield is not disturbed.

Repair Now Before It Spreads
Chips grow. A cold morning followed by the defroster, a hot afternoon followed by the air conditioning, a pothole or a car wash can all push a chip into a crack. Once a crack runs to the edge or across the driver’s view, repair is off the table. Until you can get the chip repaired:
- Avoid blasting the defroster or air conditioning straight onto the glass.
- Skip the car wash and the pressure washer.
- Cover the chip with a piece of clear tape to keep dirt and water out.
- Avoid slamming the doors, which flexes the glass.
Insurance and Chip Repair
In many cases the comprehensive or glass coverage on your auto policy covers windshield repair. The North Carolina Department of Insurance lists breakage of glass among the losses comprehensive coverage pays for. Many insurance companies waive the deductible for windshield repairs, because fixing a chip early prevents a more costly replacement later. Whether yours does depends on your policy, so check before you file. We work with your insurance company and help with the claim; our auto glass insurance claims guide covers the process in North and South Carolina.
Does a Repaired Windshield Need ADAS Calibration?
Calibration of the forward camera is tied to replacing the windshield, when the camera is taken off the old glass and fitted to the new one. A chip repair leaves the glass and the camera where they are. If the damage sits right in front of the camera, though, repair is usually not the right fix; that case calls for a new windshield and ADAS camera calibration.

Chip in the windshield?
Repair it before it spreads. Call the number on this page or send the quote form with a photo of the damage.
Is It Legal to Drive With a Chipped Windshield in NC?
North Carolina’s annual safety inspection checks your windshield wipers, not the glass itself (G.S. 20-183.3), and no North Carolina statute sets a crack size. That does not make the chip harmless: damage in your line of sight is still a safety problem, and a chip that spreads turns a repair into a replacement.

Questions
Questions people ask
How long does a chip repair take?
It depends on the size and type of the break and how many chips there are. Ask when you book and we will give you the time for your windshield.
Will the chip disappear completely?
Usually not completely. A good repair makes the damage far less visible and stops it spreading, but a faint mark can remain where the stone hit. That is one reason damage right in front of the driver is often replaced instead.
Can a 12-inch crack be repaired?
Possibly. The ROLAGS repair standard lists single line cracks up to 14 inches as repairable. Where the crack is matters as much as its length: one that reaches the edge or crosses the driver’s view is usually replaced.
Does insurance pay for windshield chip repair?
In many cases comprehensive or glass coverage covers windshield repair, and many insurers waive the deductible for it. Check your policy.
Can you repair a chip at my home or work?
Yes. Book mobile windshield repair and a technician comes to you, or visit our Greensboro shop.
Should I repair a chip or replace the windshield?
Repair when the chip or crack is small, shallow and away from the edges. Replace when the damage is large, deep, reaches the edge or sits in the driver’s line of sight.
