SHORT ANSWER
Yes — most rock chips can be repaired if you catch them within a week or two.
A typical rock chip repair takes 20–30 minutes on-site, costs $75–$120 cash (or $0 on Montana comprehensive coverage under MCA 33-23-304), and stops the chip from spreading into a full crack. Wait through a Missoula freeze-thaw week or an August thermal swing, and that repairable chip becomes a full windshield replacement at $400–$1,800. Call (737) 843-0004 the day it happens.
CHIP DAMAGE TYPES
The Six Chip Types We See Most in Missoula
Not every rock chip looks the same. The shape of the break determines whether it can be repaired.
🌟 Star Break
Central impact with multiple short legs radiating out. Most common Missoula chip type — usually from I-90 gravel spray.
✓ Repairable🔴 Bullseye
Circular impact with a dark central cone. Clean break, easy resin flow, best-case repair scenario. Common from truck spray at freeway speeds.
✓ Repairable🟠 Half-Moon
Half of a circular impact — the other half broke off. Slightly harder to repair cleanly but still fixable in most cases.
✓ Repairable⚫ Pit / Surface Chip
Small crater with no legs or cracks. Purely cosmetic. Filled with resin to prevent moisture entry and future crack growth.
✓ Repairable⚡ Combination Break
Chip plus one or more short cracks. If cracks under 6 inches and not at the edge, still repairable.
✓ Repairable if early💥 Long Crack (Over 6 in)
Extended crack or any crack reaching the edge. Structural integrity compromised — replacement is the safe call.

Four Local Causes We See Every Week
Missoula’s roads and climate combine into a windshield-killing environment. Here’s what’s actually hitting your glass.
🚚 I-90 Gravel Trucks
Constant gravel and logging truck traffic between Missoula, Bonner, and the Reserve Street corridor. Unswept shoulder gravel launches off tires at 65 mph.
🛠 Highway Chip-Seal
Summer road-work chip-seal on Reserve Street, Hwy 93, and Hwy 12 leaves loose stones on the road for weeks. Peak chip season runs June through August.
❄️ Winter Sand & Grit
MDT sanding trucks lay down grit November through March. Once temperatures rise and dry the roads, that grit becomes airborne rock spray.
🏔 Forest Service Roads
Rattlesnake NRA, Blue Mountain, Snowbowl access — unpaved and gravel-heavy. Second-biggest chip source for Missoula outdoor rigs.
What Happens If You Ignore a Rock Chip in Missoula
The exact timeline depends on weather and driving conditions. Here’s the typical progression.

Rock Chip Repair FAQ — Missoula, MT
Call (737) 843-0004 if your question isn’t answered here.
A rock just hit my windshield — what should I do right now?
Cover the chip with clear packing tape and call us today. Tape keeps moisture and dirt out of the break. Don’t use duct tape, don’t scrub the chip, don’t wash the car. The faster you call, the higher the repair success rate.
How do I know if my chip is repairable or needs replacement?
Compare to a US quarter. Smaller than a quarter, not in the driver’s direct line of sight, not touching the edge — repairable. Larger, in the driver’s view, or edge-touching — usually replacement. Call us and text a photo if you’re not sure.
Can multiple chips be fixed in one visit?
Yes. Common on Missoula outdoor rigs. Each additional chip adds about 10 minutes and $15–$30 to the price. With insurance, still $0.
Will my insurance drop me if I file a rock chip claim?
No. Glass claims filed under comprehensive coverage in Montana do not count against your driving record and do not raise your premium.
Do you come out to Rattlesnake, Grant Creek, University District, elsewhere in Missoula?
Yes — free mobile service everywhere in Missoula and out to Lolo, Bonner/Milltown, and the Wye. No trip fee within 20 km. Frenchtown, Stevensville, and Hamilton carry a small mileage fee.
Is it safe to drive with a rock chip?
Short-term yes, long-term no. A single small chip doesn’t compromise structural integrity, but every mile you drive with it exposes it to more thermal cycling and vibration. Fix it early.
