Replacing a car window? It sounds straightforward, but there’s more to it than just swapping out the glass. Small missteps—before or after the job—can lead to leaks, safety issues, or extra expenses you didn’t plan for.
To help you avoid those headaches, here are 5 mistakes to steer clear of before your auto glass window replacement—and 5 more to watch out for after it’s done.
Before Your Auto Glass Window Replacement
Before your auto glass window replacement, there are a few key things you’ll want to handle ahead of time. Skipping them can lead to delays, higher costs, or poor installation.
1. Driving with Severely Damaged Glass
If your window is badly cracked or shattered, driving to a shop can be dangerous—and in some cases, illegal. Still, many drivers take the risk and hope for the best.
- Broken glass can reduce visibility and make your vehicle unsafe.
- You could be cited under California law for driving with obstructed windows.
What to do: If the damage blocks your view or the window is unstable, consider towing your vehicle instead of driving it. It’s safer for you and everyone else on the road.
2. Delaying the Replacement
Driving around with cracked or chipped glass may not seem urgent. But that damage can spread quickly due to vibrations, potholes, and temperature changes.
- A small chip can turn into a full crack in one hot day.
- Damaged glass can compromise visibility and safety.
- It may also be illegal in California to drive with a cracked windshield or side window that obstructs your view.
What to Do: Schedule your car’s glass window replacement as soon as you notice damage that affects visibility or structure. Waiting can lead to higher costs or even a failed inspection.
3. Not Checking Your Insurance Policy
Many car owners assume they’ll have to pay the full cost out of pocket. That’s not always the case. Depending on your policy, your insurance may fully or partially cover auto glass replacement.
- California law allows for separate glass coverage in many policies.
- Some plans waive the deductible for glass-only claims.
What to Do: Contact your provider before scheduling service. AMB Auto Glass and Window Tint can also help guide you through the claim process if needed.
4. Skipping Research on Your Installer
Not all auto glass companies use the same quality parts or follow proper installation methods. Some cut corners by using cheap materials or skipping safety steps.
- Poor installation can cause leaks, rattling, or weak seals.
- Improperly installed windows may fail in an accident.
What to Do: Look for certified technicians, real customer reviews, and warranty coverage. Don’t choose a shop based on price alone. Quality and experience matter.
5. Failing to Clear the Area Before the Appointment
Techs need space to open doors, access the interior, and move around the vehicle. Personal items in or around the car can slow things down or get damaged during the process.
- Items near the window may interfere with installation.
- Dirty surfaces can affect adhesive performance.
What to Do: Clean your vehicle’s interior and remove items near the damaged window. Park in a clear, accessible space if you’ve scheduled mobile service.
After Your Auto Glass Window Replacement
Once your new window is installed, your job isn’t over just yet. What you do next can affect how well the glass holds up and whether you’ll need another repair down the line.
1. Driving Too Soon After Installation
The adhesive used in glass replacement needs time to cure. Driving too soon can cause the window to shift, loosen, or seal improperly.
- Most urethane adhesives require at least one hour to cure.
- In cooler or humid weather, curing can take longer.
What to do: Ask your technician how long you should wait. Don’t rush the process, even if your schedule is tight. It’s a safety issue.
2. Slamming Doors or Rolling Windows Down
Right after installation, the glass is still settling into place. Forceful door slams or lowering the window can compromise the seal or alignment.
- Air pressure from closing doors too hard can loosen the bond.
- Opening the window too early can interfere with the adhesive.
What to Do: Avoid slamming doors for 24–48 hours. Don’t roll down the new window unless your technician confirms it’s safe.
3. Going Through a Car Wash Immediately
Washing your car may seem harmless, but high-pressure water, brushes, or even hand-washing can damage the new seal or cause leaks.
- Automated car washes can knock the glass out of alignment.
- Even low-pressure rinsing can weaken the adhesive early on.
What to Do: Wait at least 48–72 hours before washing your car. If you need to clean the window, use a soft cloth and avoid heavy water pressure.
4. Skipping Post-Install Inspection
Some issues—like small gaps, loose trim, or minor leaks—can be caught right after the job is done. But many drivers skip the final check and notice the problem days later.
- A quick inspection can prevent bigger problems later.
- It’s easier to fix issues on-site than days after.
What to Do: Before driving away or letting the tech leave, check the alignment, look for air bubbles, and test the seal by gently pressing on the glass.
5. Not Getting a Written Warranty
Auto glass replacement should come with a warranty. Without it, you’re stuck paying again if there’s a defect, leak, or workmanship problem.
- Some shops offer limited or no warranty at all.
- Verbal promises don’t hold up when something goes wrong.
What to Do: Ask for the warranty in writing and keep a copy. AMB Auto Glass and Window Tint provides documented warranty coverage with every replacement.
