IT IS A GIVEN I should not have to say that you should go in dressed nicely with some sort automobile windshield chip repair of logo on your shirt or hat that shows you are serious and you are a professional.
If you live where it snows, consider what ice, snow, salt, and loose gravel can do to your car. The radiator can corrode without you even knowing it, minor scratches and nicks can turn rusty, and the windshield is subjected to the extremes of interior heat and exterior cold. These factors, and others, affect your vehicle when the weather changes from winter cold to summer hot.
Check with your insurance, because it's likely your insurance will pay for some forms of windshield chip repair. They may even waive the deductible, since repairing your windshield is so much cheaper than replacing a windshield. Should you need total windshield replacement, you may have to pay a deductible with your insurance.
It will be very hard to be successful with your business until you change the way you market. When a potential customer needs a repair done, you want to be the one in the crowd waving the big red flag. You want to stand out. To do so you have to give them a compelling reason to call you instead of Joe's windshield repair.
As you drive down the road, a small piece of gravel can hit your window and leave a chip. No matter how expensive your window is, the glass is still susceptible to chips. Leaving the chip alone can cause breakage and may lead to a full window replacement instead of just having it repaired.
But the best way to fix a leak is completely removing the glass and shooting a new seal. This is the only way to truly see what is happening. If the glass is removed a technician can 100% fix the underlying issue. This option may require the purchase of a new molding. Also your auto glass company will most likely require you to purchase a new glass if the old glass breaks upon removal.
