Windshield repair is a relatively cheap and quick auto body repair. The same is true for windshield replacement. Because of the comparative ease of these automotive services, drivers tend to take a fairly laissez-faire approach to their windshields: When they’re cracked, they get them repaired or replaced, and then they don’t think about them.

But doing this could mean you’re not getting the most out of the money you spend on windshield repairs. By taking some basic steps for maintenance, you can preserve your windshield after a repair. This makes it less likely you’ll have to return to the collision repair shop (at least for your windshield) and it increases your safety.

Windshield repair: a PSA

Let’s begin with a quick—but necessary—public service announcement. Do not delay windshield repair.

If you notice a crack or chip in your windshield, please visit an auto body repair shop as soon as possible. A small imperfection in your windshield, especially if it’s not in the driver’s line of sight, seems inconsequential. But sometimes these tiny cracks can spread, often suddenly. Overnight, a small chip can turn into a spiderweb that blocks your vision, thus derailing any plans you had that day.

Even seemingly minor damage can undermine the structural integrity of your windshield. This could mean a slow-speed fender bender or a piece of gravel striking the glass could shatter your windshield, making it impossible to see through and jeopardizing your safety. Windshield repair is generally quick and inexpensive—especially if it’s fixing a small chip—so it’s worth taking the time and fixing it as early as you can.

Windshield repair vs. windshield replacement

Many of the tips in this article are relevant whether you’ve had a windshield repair or a replacement. But just for the sake of clarity, it’s worth defining the two:

• Windshield repair: This term is generally used to describe when technicians fill a crack in a windshield. Auto body repair shops use special gels and fillers, as well as applicators, UV lamps, and heating methods, to fix small chips and abrasions. 
• Windshield replacement: Sometimes technicians must replace the entire windshield. This is necessary when there’s significant damage to the windshield. This is typically a more expensive service, though it’s still cheaper than most types of collision repair.

Windshield maintenance tips

After a windshield repair or replacement, the automotive glass is at its most fragile. That’s why it’s crucial to follow best practices for windshield maintenance. However, many of these tips are applicable to all situations, not just right after a windshield repair. Below are three lists for keeping your windshield in good shape in different scenarios.

After a windshield repair

After auto body repair professionals have fixed a crack or nick in your windshield, here are some things you can do to preserve their work:

Don’t wash it!

Keeping your vehicle clean is generally the best practice for maintenance. But in this case, take a break from normal cleaning procedures. It’s best not to wash your recently repaired windshield for two days to let the resin fully cure.

Don’t put pressure on it

A healthy windshield is like an elite athlete—it won’t crack under pressure. However, after a repair, a windshield is like an athlete returning from injury; it’s best to take it easy at first. Avoid leaning on your windshield and don’t push on it or scrape it.

Keep it mild

You can’t control the weather but control the temperature in and around your car as much as possible. Refrain from blasting the air conditioner or defroster and park indoors if you can, or at least in the shade during summer. 

Drive carefully

Obviously, you should always drive safely. With a recently repaired windshield, this takes on added importance. Perhaps avoid gravel roads or streets with lots of potholes for a few days.

After a windshield replacement

If you’ve had your windshield replaced with an entirely new one, here are some extra tips to consider:

No driving! (For an hour)

Wait at least an hour—two is better—after the replacement before driving. This gives the adhesive time to set properly.

Retain retention tape

If the auto body repair techs have left retention tape on your windshield, leave it. Keep it in situ for at least 24 hours to keep the seal secure.

Don’t slam your doors

It’s a good idea to simply never slam your car doors. But after windshield replacement, it’s even more important. Close your doors gently for a day or two afterward.

Crack your windows, not your windshield

Going along with the temperature advice above, if you must park in the sun on a hot day after a windshield replacement, crack your windows a bit. This prevents pressure buildup inside your vehicle, which could pop the windshield out in extreme circumstances.

Listen

Some people love the sound of whistling, while others detest it. However, you feel about it, if you hear whistling noises coming from your windshield after a replacement, that’s bad. It suggests the auto body repair technicians didn’t do a great job, or something has jostled it out of place. You’ll have to get it set properly again.

General windshield maintenance tips

Here are a few bonus tips for keeping your windshield in good condition:

Replace your wipers regularly

Worn-down blades can scratch your windshield. Replacing them before they get warped and damaged helps preserve your windshield’s condition.

Maintain a safe distance

Tailgating is dangerous for numerous reasons, not least of which is the potential of rocks, gravel, and other debris to strike your vehicle. This can easily damage your windshield.

Use proper windshield washer fluid

Other cleaners and soaps can damage the glass or the wipers, so you really should use purpose-made washer fluid.

And there you have it! Following these steps should keep you out of the auto body repair shop (at least for windshield service). But if you do notice a crack, it’s time to start searching for windshield repair in your area.
