A rock kicks up on I-285 during your morning commute. You hear the pop, glance up, and there it is — a fresh chip right in your field of vision. Now comes the question every Atlanta driver eventually faces: can this be repaired, or do I need a whole new windshield?
The answer depends on a handful of factors: damage size, depth, location, and how long the chip has been there. At Glass Inc, we evaluate hundreds of windshields every month at our Midtown shop and through our mobile service across Metro Atlanta. Here is a straightforward breakdown of when a windshield repair makes sense and when you should go with a full windshield replacement.
When repair is the right call
Most small chips and many short cracks qualify for repair, which is faster, cheaper, and just as safe as driving with an undamaged windshield.
Size and depth rules
- Chips smaller than a quarter (roughly the size of a coin) are almost always repairable.
- Cracks shorter than three inches that only penetrate the outer glass layer typically respond well to resin injection.
- Bullseye and star-shaped breaks under one inch are ideal repair candidates.
Location matters
Damage that sits away from the windshield edges and outside the driver’s direct line of sight is usually a good candidate. Edge damage tends to spread fast because the glass has less structural support near the perimeter. Chips directly in front of the driver can leave slight distortion after repair, and many technicians recommend replacement in that case to keep your view 100% clear.
Benefits of choosing repair
- Cost: A typical chip repair in Atlanta runs $60 to $120. Many insurance companies cover it with zero deductible.
- Speed: Repairs take 20 to 40 minutes. Our mobile technician can handle it in your driveway or office parking lot.
- Original factory seal stays intact: Because the existing windshield is not removed, the factory bond between glass and frame is never disturbed.
- Less waste: Repairing keeps a fully functional windshield out of the recycling stream.
How repair works
- The technician cleans the damaged area and removes any loose glass particles.
- A specialized injector is placed over the chip or crack.
- Clear resin is forced into the break under controlled pressure, filling every void.
- UV light cures the resin and hardens it to near-original strength.
- The surface is polished smooth so you barely see where the damage was.
The repaired area regains most of the original structural integrity and the crack will not spread further.
When replacement is necessary
Some damage is beyond what resin can fix. In those cases, a full windshield replacement is the only safe option.
Size and depth thresholds
- Cracks longer than six inches almost always require new glass. Even cracks between three and six inches may need replacement if they have spread into the inner laminate layer.
- Deep damage that penetrates both the outer and inner glass layers cannot hold resin effectively.
- Multiple chips or cracks scattered across the windshield weaken the overall structure even if each individual break seems small.
Location-based triggers
- Edge cracks within two inches of the windshield border compromise structural support and tend to spread within days, especially in Atlanta’s heat.
- Driver’s direct line of sight — if repair would leave any distortion, replacement gives you a perfectly clear view.
- Damage near ADAS cameras (lane departure warning, forward collision alert) may interfere with sensor calibration. In many modern vehicles, replacement with proper camera recalibration is the safer path.
Benefits of choosing replacement
- Full structural integrity restored: A new windshield bonds to the frame with fresh urethane adhesive, restoring the vehicle’s designed crash strength.
- Perfect clarity: Zero distortion, zero repaired spots.
- Long-term savings: If the existing windshield has multiple repairs or old stress fractures, one replacement eliminates the risk of repeated crack spreading.
- ADAS accuracy: New glass paired with a full camera calibration ensures your safety tech works exactly as designed.
What the replacement process looks like
- Old trim, wipers, and sensors are carefully removed.
- The technician cuts through the existing urethane adhesive.
- The old windshield is lifted out with suction cups.
- The frame is cleaned, primed, and prepped for fresh adhesive.
- A new bead of urethane is applied around the frame.
- The replacement windshield is set precisely into position.
- All trim, wipers, and ADAS sensors are reinstalled.
- The adhesive cures (typically one to two hours before safe drive-away).
- Cameras and sensors are calibrated to factory specs.
At Glass Inc, a standard replacement takes about 90 minutes, and we include ADAS calibration at no extra charge for vehicles that require it.

How Atlanta weather affects your decision
Georgia’s climate plays a real role in windshield damage. Summer temperatures on asphalt regularly push past 140 degrees Fahrenheit on the surface, and the heat causes chips to expand. A chip you could have repaired on Monday morning might be a six-inch crack by Wednesday afternoon if your car sits in a parking lot off Peachtree Street all day.
Winter brings the opposite risk. Cold mornings followed by blasting hot defrost air create thermal shock that stresses existing damage. And spring thunderstorms in April and May send debris flying across highways like I-85 and GA-400, which is why we see a spike in windshield appointments every year between March and June.
The takeaway: Get damage evaluated quickly. The sooner you act, the more likely a simple repair will solve the problem.
Insurance: repair vs replacement coverage in Georgia
Most Georgia auto insurance policies with comprehensive coverage include windshield repair at zero deductible. That means a chip fix is often free to you.
Replacement, however, typically falls under your comprehensive deductible (often $250 to $500). If the replacement cost is close to or below your deductible, paying out of pocket may make more sense than filing a claim that could affect your premium.
At Glass Inc, we work with all major insurance carriers and handle the claims paperwork for you. We will also give you an honest breakdown of whether filing makes sense for your specific situation.

Frequently asked questions
Can a long crack be repaired instead of replaced?
Cracks under three inches can usually be repaired if they are shallow and not in the driver’s direct line of sight. Cracks longer than six inches almost always need replacement. Anything between three and six inches is a judgment call that depends on depth and location — we will evaluate it and give you a straight answer.
Will my repaired windshield look perfect?
Repairs restore structural integrity and stop the damage from spreading, but you may notice a slight mark where the resin was injected. It is similar to a small blemish — visible up close but not distracting while driving.
Does windshield replacement affect my car’s resale value?
Not if it is done correctly with OEM-quality glass and proper adhesive. A well-installed replacement windshield is just as good as the original. A cracked windshield, on the other hand, can reduce your resale value significantly.
How soon can I drive after replacement?
Most modern urethane adhesives reach safe drive-away strength within 60 to 90 minutes. Your technician will give you a specific time based on the product used and current temperature and humidity conditions. For more details, read our guide on post-replacement care.
Does Glass Inc handle ADAS recalibration?
Yes. If your vehicle has lane departure warning, adaptive cruise control, or forward collision alert, we calibrate those camera systems as part of every replacement. No extra appointment needed.
