Windshield Rock Chip

You're driving down the road behind a truck. Then you hear a "BANG." A rock just struck your windshield. Amazing that a small rock striking the windshield can make that much noise. Also amazing that something made of glass can take that kind of abuse with breaking. But wait ... now you see it ... there is a chip in the windshield.

The chip is small, about the size of a dime or even smaller. Do I need to worry about this? How much would it cost to repair the rock chip, or even replace the windshield?

Rock Chip Repair Options

Fortunately rock chips are simple to repair, and the work can even be done at your home or office. A technician will inject clear epoxy resin into the damaged area which will harden. The process takes less than an hour and costs about $65.

If you do not get the rock chip repaired, water can get into the damaged area and facilitate cracking. Even if some cracks appear, the windshield can usually be repaired if the width of the crack is smaller than the size of a dollar bill.

How Much Does it Cost to Replace a Windshield?

However, even areas of damage smaller than a dollar bill may require windshield replacement if the damage is in an area of the windshield that blocks the driver's view of the road. Also, some rock chips will crack out even after repaired (see picture).

How much does a windshield replacement cost? Not as much as you might think: $300 or less for most vehicles. The cost of the windshield with installation was $230 for my Honda Civic.

Windshield replacement can be done at your home, though it's best if you have a garage where the work can be done in a controlled environment. It is important not to drive for 3 to 24 hours to allow the urethane to cure. The technician should tell you the minimum wait time.

Is It Dangerous to Drive With a Cracked Windshield?

Yes. The windshield not only protects occupants from debris (like rocks!), but is an important contributor to the structural integrity of the vehicle. In other words, it is not safe to drive with a cracked windshield. The roof can collapse in an accident, or an airbag deployment could shatter a damaged windshield and create additional hazzards in an accident.

Penny-Pinching Tips

  • Repair rock chips promptly (at a cost of about $65) to reduce the likelihood that the windshield will crack and need replacement.
  • Find a repair service that will guarantee rock chip repairs. I found one that will apply the cost of the repair to the cost of a new windshield if it cracks. The repair did crack, and they took $65 off of the bill for my replacement windshield
  • Repair or replace a damaged windshield in your vehicle. It will improve the resale value greatly, and more importantly, will be safe to drive.

        Even though there are free or really cheap auto glass repair shops, I never use them. I like to save money, but I also like a job well done. Windshield safety is ranked only third next to airbag and seat belt safety, then repairing a windshield should not be taken lightly.

        Thanks for the great tips! I had a rock chip in my windshield that I ignored for weeks until it turned into a huge crack practically overnight. I ended up having to replace the entire windshield when I could have done a simple repair if I had taken care of it early. I'll have to keep this advice in mind for future incidents. Thanks!

        Updates: The technician who replaced my windshield used adhesive with "1 hour dry time". He said it was OK to drive after 1 hour, but I waited 12 just to be safe. Also he said to avoid slamming the car doors during the drying time- the air pressure can break the seal.
