Answers, before you call.
What damage can be repaired?+
Rock chips up to the size of a half dollar, and single-line cracks up to 14 inches long.
Will my insurance pay for it?+
Yes — 95% of insurers waive the comprehensive deductible for windshield repair when you have full coverage.
Can I drive right after?+
Yes. Zero downtime. The glass is 100% sealed and you can even wash the car immediately.
What clarity should I expect?+
Chips average 85–95% clarity. Long cracks may finish at ~75%, ideally repaired within a month of damage.
Does temperature matter?+
We repair between 10°F and 100°F. We warm cold glass with soft heat and pull into the shade on hot days.
Should I wait to see if it spreads?+
Don't. A bump or a temperature swing can spread it overnight, turning a $0 fix into a full replacement.
Stop staring at that chip.
Pick up the phone. A real technician — not a script — will give you a quote and book a free mobile appointment, usually same day.
