When your windshield cracks or chips, it’s easy to feel stressed — but knowing what to expect can make the whole process smooth and worry-free. Whether you’re using insurance or paying out of pocket, here’s a complete walkthrough of what happens during a windshield replacement, so you know exactly what to expect before, during, and after your appointment.
1. Initial Inspection & Scheduling
Before anything else, a technician will inspect the damage to confirm that a full replacement is necessary. Small chips can often be repaired, but larger cracks, edge damage, or driver’s-line impairments usually mean replacement.
If you’re using insurance, most providers can handle the claim process for you. Companies like Excellent Auto Glass can verify coverage and handle the paperwork, saving you the back-and-forth with your provider.
Tip: Have your insurance policy number ready when booking your appointment. This makes verification much faster.
2. Prepping Your Vehicle
Once you arrive — or the mobile technician arrives at your location — they’ll start by prepping your vehicle. This includes:
- Protecting your hood and dashboard from debris.
- Removing wipers, moldings, and clips.
- Setting up tools and cleaning the work area.
It’s a quick step, but it ensures a safe, clean replacement with no scratches or damage to your car’s body.
3. Removing the Old Windshield
Next, the damaged windshield is carefully removed using specialized tools. The technician cuts through the urethane seal (the strong adhesive that holds your windshield in place) without damaging the car’s frame. Once loosened, the old glass is lifted out.
This part of the process usually takes around 15–20 minutes and requires precision — too much force can damage the pinch weld or paint, which could later lead to leaks or rust.
4. Cleaning and Priming
After removal, the old adhesive is cleaned off, and a primer is applied to both the pinch weld (where the glass sits) and the new windshield’s edges. This step ensures a strong, long-lasting bond between your car and the new glass.
Why this matters: Proper priming is critical. Cheap or rushed jobs that skip this step can lead to air or water leaks later on.
5. Installing the New Windshield
The technician will then position the new windshield using suction cups or a setting device to ensure perfect alignment. They’ll apply a fresh bead of urethane adhesive and press the glass firmly into place.
Once set, clips and moldings are reattached, and any protective coverings are removed. The technician will clean up excess adhesive and wipe down your new glass.
6. Curing and Safety Wait Time
After installation, the adhesive needs time to cure before you drive your car. Depending on the product used, this can range from 30 minutes to a few hours. The technician will tell you the exact “safe drive-away time.”
Driving too early can weaken the bond, so it’s important to wait the full recommended period.
7. Final Cleanup & Inspection
Before wrapping up, your technician will check for proper seal, alignment, and clarity. You’ll also get an overview of post-installation care:
- Avoid high-pressure car washes for 24–48 hours.
- Don’t remove retention tape early (it helps seal edges).
- Keep windows cracked slightly on hot days to reduce air pressure.
You’ll also get an invoice and any insurance paperwork to confirm the replacement is complete.
