Try to find someone who is reliable when it comes to auto glass repair. Many times the people that you talk to will have had to have some type of auto glass repair done and can recommend who they used to get the job done. Ask around and see what happens.
Consider the possibility of doing an auto glass repair on your own. If you are doing this look into what it will take as far as tools as well as materials and look into comparing the costs to see if this would be a worthwhile venture or if it would be better to have someone else do it.
