# How Long Does Rock Chip Repair Take in Calgary?

> A typical rock chip repair takes 20–30 minutes from the moment a technician starts the job. Drive away immediately — UV-cured resin sets the second the lamp turns off.

## What happens in the 20–30 minutes

1. **Inspection & cleanout — 3–5 min.** Identify chip type. Vacuum moisture, dust, glass.
2. **Resin injection — 8–12 min.** Pressurized bridge clamps over chip. Vacuum removes air. UV-curable resin forced under pressure.
3. **UV curing — 5–8 min.** UV lamp hardens resin. Glass returns to 80–95% original strength.
4. **Pit fill & polish — 2–5 min.** Final pit-resin bead, cured, scraped flat.

Two chips in a single visit: +5–10 minutes total, not double.

## Why not faster?

Resin viscosity is temperature-dependent. A reputable Calgary tech waits for windshield surface temperature to reach 5–10°C before injection. Rushing this is the main cause of repair failure within a month. UV cure time is fixed by lamp wattage and resin spec — under-curing fails in freeze-thaw.

If a quote says "10-minute repair", walk away.

## Drive away time

| Service | Active time | Drive-away |
| --- | --- | --- |
| Rock chip repair | 20–30 min | Immediate |
| Windshield replacement | 60–90 min | 1–24 hrs (adhesive cure) |

**First 24 hrs after repair:** avoid automated car washes; skip extreme temperature shocks (cold AC on sun-heated glass).

## What can stretch the job

- Multiple chips: +5–10 min each.
- Contaminated chip (rain, washed car, weeks-old): +5–15 min cleaning.
- Edge chips near the frit band: lower-pressure injection, longer.
- Temperature extremes (−25°C or +28°C+): pre-warming or shading time.

Resin doesn't cure well below 0°C ambient — Calgary winters mean 3–5 reschedule days/year on weather.

## End-to-end timing

Most customers go from booking to back on the road in 24–48 hours. Mobile saves the round-trip and the lobby wait.

## FAQ

**Same-day repair?** Often yes if you book in the morning.
**How long does the repair last?** Permanent for the life of the windshield.
**Will the chip still be visible?** Most chips reduce to a faint mark. Fully invisible is rare.
**Stay with my car?** No — many leave keys with us.
**How quickly to book?** Within a few days. Calgary's freeze-thaw can spider a chip in a single Chinook cycle.
