A piece of gravel flies off a construction truck on I-285 and cracks your windshield. A break-in at a parking deck in Midtown shatters your side window. A falling branch during a spring thunderstorm spider-webs your rear glass. Every day, Atlanta drivers deal with auto glass damage — and most are not sure whether they need a repair, a replacement, or if they can just keep driving.
This guide covers the types of damage you might encounter, how to decide between repair and replacement, what each process involves, and how to protect your glass going forward.
Types of Auto Glass Damage
Not all damage is the same, and the type determines your options:
Chips
Small dings or pits caused by debris impact. They come in several forms:
- Bullseye — Circular with a cone-shaped mark. Usually repairable if smaller than a quarter.
- Star break — Short cracks radiating from a central point. Repairable if the legs are under 3 inches.
- Half-moon — A partial bullseye shape. Usually repairable.
Cracks
Linear fractures that can run a few inches or the entire width of the windshield:
- Stress cracks — Caused by temperature changes, not impact. Common in Atlanta during summer when the glass surface exceeds 150 degrees and then gets hit with cold AC air.
- Edge cracks — Start within 2 inches of the windshield edge. These almost always spread to the full length of the glass and require replacement.
- Floater cracks — Start in the center of the glass, away from the edges. May be repairable if under 6 inches.
Shattering
Complete breakage of the glass. Tempered side and rear windows shatter into small, blunt pieces by design. Laminated windshields may crack extensively but stay in one piece due to the vinyl interlayer. Either way, shattered glass requires immediate replacement.
Scratches
Surface abrasions from worn wiper blades, sand, or cleaning with abrasive materials. Light scratches can sometimes be polished out. Deep scratches that catch your fingernail typically mean the glass needs replacement.
Repair vs. Replacement: How to Decide
Here is a straightforward guide:
| Condition | Repair? | Replace? | Why |
|---|---|---|---|
| Chip smaller than a quarter | Yes | No | Resin fills the damage and restores integrity |
| Crack under 6 inches, not at edge | Usually yes | Sometimes | Depends on location and depth |
| Crack over 6 inches | No | Yes | Too long for resin to hold reliably |
| Edge crack (within 2” of border) | No | Yes | Will spread; structural weakness |
| Damage in driver’s line of sight | Rarely | Usually yes | Even repaired damage can distort vision |
| Multiple chips or cracks | No | Yes | Too many stress points for reliable repair |
| Side or rear window damage | No | Yes | Tempered glass cannot be repaired |
When in doubt, have a professional evaluate the damage. At Glass Inc, we always recommend the least expensive option that keeps you safe. If a $50 repair will solve the problem, we say so.
How Auto Glass Repair Works
Repair is the preferred option when the damage qualifies. The process is quick and straightforward:
- Cleaning — The technician cleans the damaged area to remove any dirt, moisture, or debris from inside the chip or crack.
- Resin injection — A specialized clear resin is injected into the break using a vacuum device. The resin fills the void and bonds to the surrounding glass.
- UV curing — Ultraviolet light hardens the resin, restoring the structural integrity of the glass.
- Polishing — The surface is smoothed to match the surrounding glass. The result is a nearly invisible repair that restores about 80-95% of the original clarity.
Time: 20-30 minutes for most chip repairs. Cost: $50-$100 at Glass Inc. Many insurance policies cover repairs with no deductible. Driving: You can drive immediately after repair.
How Auto Glass Replacement Works
When repair is not an option, full replacement is necessary. Here is what the process looks like at Glass Inc:
- Old glass removal — The technician cuts away the urethane adhesive holding the old glass and carefully lifts it out, protecting your paint and trim.
- Surface preparation — The pinch weld (the metal lip around the opening) is cleaned, any old adhesive is trimmed, and fresh primer is applied to ensure a strong bond.
- Glass selection — The replacement glass is matched to your vehicle’s exact make, model, year, and trim level. If your car has rain sensors, a heads-up display, or ADAS cameras, the glass must accommodate those features.
- Installation — The new glass is set into a bead of urethane adhesive and positioned precisely in the opening. Proper alignment is critical for water tightness and structural integrity.
- ADAS calibration — If your vehicle has a forward-facing camera (most cars made after 2015), the camera is recalibrated to factory specifications using specialized equipment.
- Curing — The adhesive needs time to cure before the vehicle is safe to drive. The cure time depends on the adhesive type and ambient temperature, but it is typically 1-2 hours.
- Quality check — We inspect the seal, test for leaks, verify sensor operation, and confirm the glass sits flush with the body.
Time: 60-90 minutes for most replacements, plus cure time. Cost: $200-$900+ depending on vehicle and glass type.

Why You Should Not Wait
Putting off auto glass repairs in Atlanta is a gamble that rarely pays off:
- Cracks spread fast — Atlanta’s extreme temperature swings (hot surface glass vs. cold AC air) cause cracks to grow rapidly. A small chip can become a full-length crack in 24-48 hours during summer.
- Structural risk — A cracked windshield cannot fully support the roof during a rollover or provide proper airbag backstop during a collision.
- Legal issues — Georgia law requires an unobstructed view through the windshield. Officers can cite you for driving with a cracked windshield, with fines starting around $150.
- Cost escalation — A $50 chip repair becomes a $400 replacement once the crack spreads. Every day you wait increases the likelihood of needing the more expensive option.
Protecting Your Glass After Service
Whether you just got a repair or a full replacement, these habits will help your glass last:
- Wait the full cure time after replacement. Do not drive, slam doors, or go through a car wash until the adhesive has fully cured. Your technician will tell you exactly how long to wait.
- Replace wiper blades every 6-12 months. Worn blades drag grit across the glass and cause micro-scratches that degrade visibility over time.
- Maintain following distance. On Atlanta highways like I-85, I-75, and the Downtown Connector, loose gravel and construction debris are constant threats. Stay back from trucks hauling rock or construction materials.
- Park under cover during storms. Spring hailstorms in north Georgia can crack or pit windshield glass. A garage or carport provides the best protection.
- Clean off pollen regularly. During Atlanta’s spring pollen season, that fine yellow dust can etch glass if left to bake in the sun for extended periods.
- Avoid thermal shock. Do not blast your defroster or AC directly onto a windshield that is extremely hot or cold. Let the temperature change gradually.
FAQs About Auto Glass Repair and Replacement
How do I know if my chip can be repaired? If the chip is smaller than a quarter and no cracks extend from it, repair is usually possible. Chips in the driver’s direct line of sight are sometimes replaced instead of repaired to ensure optimal visibility.
Will my insurance cover auto glass work? Most comprehensive policies cover auto glass damage. Many cover chip repairs with no deductible. Glass Inc works directly with all major insurance carriers and handles the claim process for you. Contact us to verify your coverage.
Can I drive immediately after a repair? Yes, you can drive immediately after a chip or crack repair. After a full replacement, you need to wait for the adhesive to cure — typically 1-2 hours.
What is the difference between OEM and aftermarket glass? OEM glass is made by the same manufacturer as your vehicle’s original glass. Aftermarket glass meets federal safety standards but may differ in tint, thickness, or acoustic properties. Glass Inc primarily uses OEM and OEM-equivalent glass for the best fit and performance.
Do all vehicles need ADAS recalibration after replacement? Not all, but most vehicles made after 2015 with driver-assist features (lane departure warning, adaptive cruise, automatic braking) require recalibration. Glass Inc has the equipment and training to handle this in-house.
