How Long Does It Take to Fix a Cracked Windshield?
Quick Answer
30–60 minutes for a chip repair; 1–2 hours for a full windshield replacement. Adhesive cure time adds 1–24 hours before the vehicle is safe to drive.
Typical Duration
Quick Answer
A windshield chip or small crack repair takes 30–60 minutes. A full windshield replacement takes 1–2 hours for the glass work, but the urethane adhesive needs 1–24 hours to cure before the vehicle can be driven safely.
Repair vs. Replacement: When Each Applies
| Criteria | Repair | Replacement |
|---|---|---|
| Crack length | Under 6 inches | Over 6 inches |
| Chip diameter | Under 1 inch | Over 1 inch or multiple chips |
| Location | Away from edges and driver's line of sight | In driver's view or at windshield edge |
| Depth | Outer layer only | Through both layers of glass |
| Time for service | 30–60 minutes | 1–2 hours |
| Drive-away time | Immediately | 1–24 hours after service |
Windshield Repair Timeline
Step 1: Inspection (5 minutes)
A technician examines the damage to determine if repair is viable. Chips smaller than a quarter and cracks under six inches are generally repairable.
Step 2: Cleaning and Preparation (5–10 minutes)
The damaged area is cleaned to remove debris and moisture. A vacuum may be applied to extract air from the crack.
Step 3: Resin Injection (10–20 minutes)
Clear resin is injected into the chip or crack using a specialized bridge tool. The resin fills the void and bonds with the surrounding glass.
Step 4: Curing (5–10 minutes)
Ultraviolet light is used to cure and harden the resin. The technician then scrapes away excess resin and polishes the surface.
Total active repair time: 30–60 minutes. The vehicle can be driven immediately afterward.
Full Windshield Replacement Timeline
Step 1: Old Windshield Removal (20–30 minutes)
The technician removes the wipers, cowl, and trim pieces, then cuts through the old urethane adhesive and lifts out the damaged windshield.
Step 2: Surface Preparation (10–15 minutes)
The pinch weld is cleaned, old adhesive is trimmed to a consistent layer, and a primer is applied to ensure proper bonding.
Step 3: New Windshield Installation (15–20 minutes)
Fresh urethane adhesive is applied to the new windshield or the vehicle frame. The new glass is carefully positioned and pressed into place.
Step 4: Reassembly (10–15 minutes)
Trim, cowl, and wipers are reinstalled. The technician checks for proper alignment and seal.
Step 5: Cure Time (1–24 hours)
This is the critical waiting period. Modern fast-cure adhesives may allow driving after 1 hour, but full cure takes 24 hours. During cure time, avoid car washes, slamming doors, and driving on rough roads.
Mobile Service vs. Shop Visit
Mobile windshield services come to your location and typically take the same amount of time as an in-shop visit. The main advantage is convenience—you avoid the drive to a shop and the wait. Most insurance-covered replacements offer mobile service at no extra cost.
Factors That Can Extend the Timeline
- ADAS recalibration: Vehicles with advanced driver-assistance systems (lane departure, auto-braking) may need camera recalibration after replacement, adding 30–60 minutes
- Specialty glass: Heated, acoustic, or heads-up display windshields may require additional fitting time
- Cold or humid weather: Adhesive cure times increase in low temperatures or high humidity
- Custom or rare vehicles: Windshields for luxury or uncommon models may need to be ordered, adding days of wait time
