Rock Chip & Windshield Crack Repair in Missoula

Got a fresh chip from a gravel truck? Catch it early and we can usually fill it where your car is parked in about 25 minutes, before a cold morning turns it into a crack.

Rock Chip Repair in Missoula and Western Montana

Rock chip repair is the cheapest glass work you'll ever pay for, as long as you get to it in time. Around here the chips come from everywhere: gravel trucks, sanded roads in winter, the pickup ahead of you on the highway. One ping and there's a little star in the glass.

Left alone, that star rarely stays small. Epic Auto Glass fills it with resin right where the vehicle sits, usually in about 25 minutes. You don't lose your afternoon, and you keep the factory seal on your original windshield.

Repair has real advantages over a new windshield. It costs less. It's quicker. It's often covered by insurance. And a proper repair still meets safety requirements. The catch is timing, so the sooner you call, the better your odds.

Signs You Need Rock Chip Repair

  • A small bullseye, star or half-moon mark in the glass
  • A chip no bigger than a quarter
  • A short crack that hasn't started to wander
  • A chip you can feel with a fingernail
  • Damage that showed up after following a truck or driving a sanded road
  • A chip that looks a little bigger than it did last week

How It Works

  1. Tell us where the chip is

    Call, or email a photo with your vehicle info, and we'll let you know if it looks repairable.

  2. Pick a place

    We come to your driveway, your work parking lot or wherever the car will be.

  3. Clean and fill

    We clear the break of glass fragments and debris, then inject resin under pressure so it flows into every leg of the chip.

  4. Cure and finish

    The resin is cured, the surface is smoothed, and the spot is polished flush with the glass. The whole visit is usually about 25 minutes.

Fix It Before It Spreads

The rule of thumb in the auto glass trade is simple. If the damage is smaller than a quarter, it can usually be repaired. Once a crack runs past about 2½ to 3 inches, you're most likely looking at a new windshield instead.

Why do chips grow? A chip is a weak point with tiny fractures branching off it. Every bump, door slam and temperature swing puts stress on those fractures. Montana winters make it worse. On a cold morning, blasting the defroster warms the inside of the glass while the outside stays frozen. That difference pulls on the chip, and a small break can run into a long crack before you're out of the driveway. Water getting into the chip and freezing does the same thing.

Here's what the repair actually does. The resin fills the air pockets in the break and bonds the glass back together. That stops the spreading and restores strength to the spot.

What will it look like afterward? Most repairs leave a faint mark where the impact point was, much less noticeable than before. It won't vanish entirely, but it will be clearer, stronger and far less likely to grow. Until we get there, keep tape or a clean sticker over the chip to keep dirt and moisture out.

What Affects the Price

  1. Number of chips

    One chip is one fill; several spots take a bit more work.

  2. Size and type of break

    A simple bullseye is easier than a star with long legs.

  3. Where it sits

    Damage near the edge or in the driver's direct view can change what's possible.

  4. Your coverage

    Plenty of policies treat chip repair differently than replacement, so check with your insurer. Our insurance claims page walks through it.

Rock Chip Repair FAQs

Can every chip be repaired?

No. Damage larger than a quarter, long cracks, or breaks right at the edge of the glass usually need replacement. We'll tell you honestly which one you've got.

Will insurance pay for a chip repair?

Often, yes. Many insurers waive the deductible for chip repairs, but policies differ, so check yours.

Can I wash my car after a repair?

Yes. The resin is cured before we leave, so normal driving and washing are fine.

Do I need to be home?

Not necessarily. Tell us where the car will be when you book, and we can often do a mobile repair while you're at work.
