It can be terribly frustrating when your garage door becomes broken or begins to not work properly.
  Generally you have two options: You can attempt to have your current door fixed, or you can replace it with a new one that will hopefully work better.
  Both approaches have their advantages and disadvantages.
  Fixing the door tends to be cheaper, but may not always work, especially if you have an older door for which getting parts may be difficult or if the motor itself has burned out.
  It's important to find a repair person that you can trust so that the cost of fixing a door does not get out of hand.
  Replacing the door has advantages as well: Though it may cost a bit more, you will have the chance to install a more modern door which is virtually guaranteed to work better, and may better match your architecture and design of the house.
  Be sure to shop carefully to get the best deal on the door, and to get multiple estimates for installation of the door.
  If possible, get a long warranty on the installation so that if anything goes wrong in the future or if the installation was faulty, you will be able to get the installation guy back out to your location to fix it at no cost to you.
  Getting a new garage door is also a great chance to add a new color or style of door to your house that you may not have done otherwise.
