How do I adjust a garage door so there is no gap when closed?

Recently I replaced the concrete garage floor. Prior to that, the garage door was tight across the length of the door where the door met the floor. Now that I have a new concrete floor that is level, I have a half inch gap on the right side (on the inside of the garage, looking at the door). It tappers from the left to the right. (Tight on the left - gap on the right.) Since the garage floor was obvious not level when the door was installed but now it is, how do I adjust the door so it is level and tight to the floor - the whole width? (I do have a garage door opener.)Thanks in advance for your input.

    I think I would have a professional come in and do it. It probably will take them way less time to figure it out without all the headaches and frustration you may run into. I have a local carpenter who occasionally looks at mine and it doesn't take him long because he does garage doors all the time.
