Getting your windshield replaced is only half the job — proper care afterward ensures it lasts, seals correctly, and looks as clear as the day it was installed. Here’s a simple, step-by-step guide to help you protect your investment and avoid the most common post-installation issues.
1. Don’t Drive Too Soon
Your technician will tell you how long to wait before driving — typically 30 minutes to 2 hours, depending on the adhesive used.
This “safe drive-away time” allows the urethane to fully set and ensures your windshield won’t shift under vibration or air pressure while driving.
If you’re unsure, wait at least an hour before getting behind the wheel.
2. Leave the Retention Tape On
Most technicians apply retention tape around the edges of your windshield to help hold the moldings in place while the adhesive cures.
It might not look great, but don’t remove it early — even overnight. Removing it too soon can cause the seal to lift slightly, leading to leaks or air noise later.
3. Avoid High-Pressure Car Washes
It’s tempting to show off your new glass with a wash, but high-pressure hoses or automatic car washes can disrupt the new seal.
Wait at least 48 hours before washing your car — and if you must clean it, use a gentle hand wash with mild soap and no direct water spray at the edges.
4. Crack the Windows Slightly on Hot Days
After a windshield replacement, air pressure inside your car can build up on hot days and push against the curing adhesive.
Leave your windows slightly open (even half an inch) for the first day or two to let the pressure equalize naturally.
5. Avoid Slamming Doors
The same logic applies to door slams. A strong air pressure wave can disrupt the seal if the adhesive hasn’t fully cured.
Close your doors gently for the first 24 hours — especially if you have a tightly sealed vehicle like a newer SUV or sedan.
6. Check for Leaks or Noise
After a few days, it’s smart to do a quick self-inspection.
Drive at highway speed and listen for whistling or air noise. If you notice moisture on the dashboard after rain, contact your installer right away — reputable shops like Excellent Auto Glass will fix it free of charge under warranty.
7. Don’t Tamper with the Molding
Don’t try to press, pull, or adjust the black molding around the glass. It’s there to protect the edges and help the adhesive bond. If something looks uneven, let a technician handle it.
Final Thoughts
A new windshield should last for years — but only if it’s treated right in the first few days.
Following these simple steps ensures your glass seals perfectly, stays clear, and keeps you safe.
