Frequently Asked Questions About Windshield Repair

View all questions here

What type of windshield damage can be repaired?

A good rule of thumb, rock chips up to the size of a half dollar and single line long cracks up to 14 inches in length.

Would a rock chip spread further if I don’t get it fixed?

No one really knows the answer to this. But, a bump in the road or temperature changes can cause it to spread. It is a gamble to put off getting it fixed.

Can I drive the car as soon as the technician is finished?

Yes. There is ZERO downtime with windshield repair. The glass is 100% sealed and can be driven immediately. You can treat the windshield as you normally would (i.e. wash your car).

Will my insurance pay for this mobile service?

Yes, 95% of all insurance companies will waive your comprehensive deductible and pay for the windshield repair as long as you have full coverage. Always consider this as a claim and in some cases could affect your rates. Best thing to do is check with your agent.

What can I expect to see once the windshield repair is complete?

Generally speaking, on an average chip repair, you should always get 85 – 95% clarity. Clarity depends on many factors: a) how the rock impacted the windshield, b) the size of the repair, c) how much glass is missing from the point of impact, d) the slant of the windshield, e) how long the damage has been there. NOTE: On long cracks, depending on the location of the crack & angle of the windshield, you may only get 75% clarity on the repair. Ideally, they should only be fixed if less than one month old .

At what temperature can a windshield repair be done?

From 10 to 100 degrees fahrenheit. On a cold day you just warm up the glass to simulate a 70 degree day using soft heat (heat lamp or defroster). If the sun is out, you can use the heat of the sun. Glass is alway much warmer than the outside air temp when in the sun. On a hot day pull in the shade and open the windows.
