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.

For that reason, many companies will happily waive the deductible if the existing windshield can be repaired. So you may be able to have that chip or crack fixed without paying anything at all.
To change the entire windshield will cost the car owner hundreds of dollars. If they decide to bring the car to a car shop for fix auto glass, they will spend more money. Repairing a windshield at home only takes an hour of dedicated work, and it is extremely easy to repair cracks and chips.
As a windshield installer for the past thirty five years, let me give you three good reasons not to repair your windshield. As windshield repair is a gimmick in my opinion.
Jolt your car or windows. Try to avoid slamming doors or shutting doors with the windows all the way up. Creating extra pressure inside the vehicle in this way can cause the crack to spread.
One way to find out about a companies reputation is to call other repair techs and ask them which company they bought their repair kit from and are they satisfied with it. Call the company itself and ask to speak to the owner. You will get a good feel for the company after having spoken with the customer service people and the owner.
