Summertime Auto Glass Repairs – Why Does the Heat Matter?

To you, a cracked windshield is an annoyance whether it happens during the dog days of summer or smack dab in the middle of a frigid winter.  But to a good auto glass repair company, the summertime heat plays a major role in how they approach your damage.


Because hot weather and windshields don’t really mix.  Specifically, it’s the change in temperature that’s the problem.  After all, if it’s 100° outside, you’re likely going to have the air conditioner cranking at full blast inside your car.  Sure, you’ll feel cool and comfy, but all of that cold air will be blowing on your windshield — and that’s where the problem lies.

One side of your windshield is getting blasted by cold air, while the other side is getting blasted by the hot outdoor air.  That dramatic difference in temperatures can cause an existing chip or crack to spread across your windshield.

But that’s not the only risk you face during the summer.

If you use the wrong auto glass repair company — and they don’t know how to adjust their work during the heat of the summer — you can actually wind up with more damage!  So, how do you prevent your auto glass repair technician from turning an annoyance into a full-blown problem?

See if they place their hand on the windshield before doing anything else.

If the windshield is too hot, a number of problems can arise — including a breakdown in the windshield’s internal safety layer and resin that cures before it has time to completely cover the damage.

The rule of thumb that auto glass experts go by is testing the temperature of the glass with their hands.  If the windshield is too hot for them to leave their hand on comfortably for a few seconds, it’s too hot to repair.  That’s why a good windshield repair expert will NEVER work on a hot day before doing this test first!

See if they have a digital thermometer to do a secondary temperature test.

The hand-on-windshield test is a good start, but you need more than that.  An expert technician will use a digital thermometer to take the windshield’s temperature, and if it’s over 100°, they’ll know to cool it before he begins working.

Find out how they are going to cool the windshield.

As we’ve already discussed, dramatic temperature changes can damage your windshield.  So, if your auto glass technician thinks it’s a good idea to pour cold water on your hot windshield or to turn the air conditioner on full blast and point the vents at your hot windshield, they are not the experts they claim to be!

A good way to cool the windshield gradually is to use the floor vents in your car’s air conditioner.  That way, cold air will slowly make its way up to the windshield, instead of blasting it.

Ask them if they are going to warm up the resin first.

One of the most common problems that pops up during a summertime repair is an auto glass technician using resin that’s colder than the windshield.  It may not seem like a big deal, but cool resin can actually make the existing damage worse — or even cause brand new damage!

That’s why an expert technician will test the temperature of the resin along with the temperature of the windshield.  If the resin’s temperature is more than 10° lower than the windshield’s temperature, they will know they need to make some adjustments.

Now that you know what an expert SHOULD do, it will be easy to see if your auto glass repair company is doing everything right.  If they’re not, find another one.  Your windshield is too important to risk!
