Many small chips, often smaller than a quarter, can be repaired if they are outside the driver’s direct line of sight and have not spread. Larger cracks, damage at the edge of the glass, or chips directly in front of the driver usually mean replacement. Acting quickly gives you the best chance of a simple repair.
Temperature changes, potholes, and car washes can turn a chip into a crack overnight. Here is how to decide what to do next.
Step 1: Check the Damage
- Size: small chips and short cracks are often repairable; long cracks usually are not.
- Location: damage in the driver’s view or near the edge often requires replacement.
- Depth: damage through both layers of laminated glass cannot be repaired.
- Number: several chips close together may weaken the glass.
Cover the chip with clear tape to keep out dirt and moisture until it is inspected.
Step 2: Know About ADAS Recalibration
Many newer vehicles have cameras and sensors mounted near the windshield for features like lane departure warnings and automatic emergency braking. These are part of advanced driver assistance systems, often called ADAS. After a windshield replacement, the camera may need recalibration so these features work correctly.
Ask the glass shop whether your vehicle needs recalibration, whether they perform it in-house or through a partner, and whether it is included in the quote. Skipping a needed recalibration can leave safety features working incorrectly.
Avoid These Common Mistakes
Do not run the defroster on high or blast cold air on a hot windshield right after noticing a chip, since sudden temperature changes can spread cracks. Avoid slamming doors and automatic car washes until the damage is repaired. Skipping recalibration after replacement is another mistake, because driver assistance features may react incorrectly. Ask for written confirmation that calibration was completed when it is required for your vehicle.
Step 3: Check Insurance and Choose a Shop
Comprehensive auto insurance often covers glass damage, and some policies cover chip repairs with little or no deductible. Call your insurer or check your policy before scheduling. Ask the shop about glass type, warranties, and how long to wait before driving after replacement so the adhesive can cure.
Many drivers save a local shop’s number ahead of time; auto glass and repair shops on Domow can be compared by service area and calibration ability. Comparing a few providers there makes it easier to find one that handles both replacement and calibration.
Act Fast, Ask the Right Questions
Small chips outside the driver’s view can often be repaired quickly, while large or edge damage needs replacement. Protect the chip, ask about ADAS recalibration, check insurance coverage, and confirm warranties and cure times. Domow can help you find glass shops nearby.
Frequently Asked Questions
Many shops repair chips about the size of a quarter or smaller and short cracks, depending on location and depth. Damage in the driver's direct view may require replacement even if small. A technician can confirm after inspecting the glass.
Many comprehensive auto policies cover glass damage, and some insurers waive the deductible for chip repairs. Coverage varies by policy and state. Call your insurer or check your policy documents before scheduling to understand what you will pay. Keep a copy of the policy handy.
It is the process of adjusting cameras and sensors used by driver assistance features, such as lane keeping or automatic braking, after windshield replacement. Proper calibration helps these features work as designed. Ask whether your vehicle requires it and whether it is included in the price. Request written confirmation of calibration.
It depends on the adhesive used and conditions like temperature. Many shops specify a minimum drive-away time, sometimes an hour or more. Follow the technician's instructions, since driving too soon can affect the seal and safety performance of the glass.
