Rock Chip Repair Vancouver

How it goes, minute by minute

1. 1

   Assess the break≈5 min

   Under angled light we identify the break type — bullseye, star, combination, or half-moon. Each one takes resin differently, and a few shouldn't take it at all.

2. 2

   Dry and clean the chip≈5–10 min

   Moisture inside the break blocks resin. On a wet day we gently warm the glass and dry the break before anything else happens.

3. 3

   Vacuum cycles≈5–10 min

   A bridge tool seals over the chip and pulls a vacuum, drawing air and moisture out of every fracture leg. You can't fill a space that's still full of air.

4. 4

   Pressure cycles≈5–10 min

   Resin with a refractive index close to glass is driven into the break under pressure, alternating with vacuum until the legs go dark — the visual sign they're filled.

5. 5

   Cure and finish≈5 min

   A UV lamp hardens the resin in place, the surface crater gets a thicker pit resin, then a razor-flush scrape and polish.

A standard chip repair takes about 30 minutes, and you can drive away immediately — the resin is fully cured under UV before you leave. Additional chips add roughly 10–15 minutes each.

The coin-size rule

Our working guideline is simple: if the entire damaged area disappears behind a coin, the odds of a successful repair are strong. Bigger than that, or damage with a crack already running off it, and you're into the territory covered by our Crack Repair or Replacement guide. Location matters too — damage near the glass edge or directly in the driver's sightline gets a stricter look, and we'll tell you exactly why in person rather than talking you into anything.

What the resin actually does

A stone chip is a small cone-shaped fracture with legs radiating into the glass. The reason you can see it is air: the fracture faces reflect light where glass should pass it. The repair replaces that air with resin. Vacuum cycles pull the air and moisture out of the legs; pressure cycles drive in a resin whose refractive index sits close to the glass itself; UV light then hardens it into a solid that bonds the fracture faces back together. Done properly, the repair restores much of the glass's local strength and — this is the real goal — removes the stress concentration that lets a chip become a crack. It's the highest-value 30 minutes in autoglass.

Why chips spread — and why they pick the worst moment

Windshield glass lives under tension, and a chip is a stress riser waiting for an excuse. Cold is the classic one: park outside on a near-freezing night, start the car, and hit the defroster — the inner layer warms and expands against a frigid outer layer, and the chip runs while you watch. Potholes and curb strikes flex the whole windshield aperture. Car washes stack two triggers at once: hot water on cold glass and a high-pressure lance passing over the break. Chip the gravel gremlin does his recruiting on highway grit, but it's usually a February morning that finishes the job.

This is exactly why waiting converts a 30-minute repair into a full replacement. Once a leg runs past the coin zone or reaches the edge of the glass, no resin can bring it back — the windshield is done, along with the extra time and cost that comes with it. A chip repaired this week stays a chip; a chip left for the season becomes an appointment on the Windshield Replacement page.

What a finished repair honestly looks like

A repair is structural first, cosmetic second. Expect the visual mark to improve substantially — most people stop noticing it within days — but a faint blemish, a small dark fleck, or a slight ghost of the original break often remains, especially in low direct sun if you know where to look. What you will not see is the chip growing. If perfect optics matter more to you than keeping the original glass, tell us; that's a replacement decision, and we'll lay out both paths honestly.
