Stop The Crack
Before It Spreads.
A rock chip today is a full windshield replacement tomorrow. Duke Auto Glass repairs chips and small cracks across St. Louis and Jefferson County — usually in under 30 minutes, often $0 out-of-pocket with comprehensive insurance.
How Rock Chip Repair Works.
When a rock kicks up off the highway and hits your windshield, it leaves a small pit or star-shaped chip. The glass around that chip is now under tension — every temperature swing, every bump, every defroster cycle is pushing it toward a full-blown crack across your line of sight.
Rock chip repair stops that. We clean the chip, vacuum out air and moisture, inject a clear resin under pressure, and cure it with UV light. The result: the structural strength is restored, the chip becomes much less visible, and the crack stops spreading. Most chips smaller than a quarter — and not directly in the driver's view — are good candidates.
Best of all, most comprehensive insurance policies in Missouri cover rock chip repair at $0 deductible because it prevents a much more expensive windshield replacement claim later. Call us and we'll walk you through it.
Don't wait.
A repairable chip can turn into a full crack overnight — a hot day, a cold morning, a pothole. Once it spreads more than a few inches or reaches the edge of the windshield, repair is no longer an option and you're looking at a full replacement.

Auto Glass FAQ.
How much does windshield replacement cost in St. Louis?
Most windshield replacements in the St. Louis and Jefferson County area run between $250 and $500 for standard cars and SUVs, depending on your make, model, and whether you need OEM or quality aftermarket glass. Vehicles with rain sensors, heated wipers, or ADAS features can run higher. Call (636) 331-4148 for a free, no-pressure quote on your exact vehicle.
Do you offer mobile windshield replacement?
Yes. Duke Auto Glass is a mobile auto glass service — we come to your home, your office, or wherever your vehicle is parked across St. Louis, Festus, Arnold, Imperial, Hillsboro, and surrounding Jefferson County, MO communities. No need to take time off to drop your car at a shop.
How long does it take to replace a windshield?
The install itself usually takes 45 to 90 minutes. After that, the urethane adhesive needs about one hour of safe drive-away time before the vehicle can be driven safely. We walk you through the exact cure time for your job on the day of service.
Can a rock chip be repaired instead of replacing the windshield?
Often, yes. If the chip is smaller than a quarter and not in the driver's direct line of sight, we can usually inject resin and stop the crack from spreading. Rock chip repair is fast (often under 30 minutes), much cheaper than replacement, and is frequently covered 100% by comprehensive insurance with no deductible.
Does insurance cover windshield replacement?
If you carry comprehensive coverage, your insurance usually covers windshield replacement. Some Missouri policies even waive your deductible entirely for glass claims. We're happy to walk you through the basics — call us and we'll help you understand your options before you file.
