You open the door between your home and your attached garage, and cold wind rushes into the home. If this happens, then you are wasting money on your heating bills. Not only that, but your car and anything else stored in the garage is getting cold - which can damage it. If you live in a place with "decent" winters, then you should take the time to properly winterize your garage, and check this every year before the first snow hits.
When it comes to your garage door, the primary thing to be concerned with is weatherstripping. This is the strip that forms a seal between your garage door and its frame, and it does get worn out, creating cracks that let in that cold air.
If you are getting those cold blasts, you need to remove and replace the weatherstripping. Make sure to remove all of the old sealant, so the new has a smooth surface to adhere to. Make sure the strip is aligned so the rubber flap flattens against the door when it is closed. If you have consistent problems, consider more expensive weather stripping. A weather seal at the bottom of the door can also be helpful, especially if you have issues with insects in your garage.
Additionally, the door itself should be insulated. This generally involves putting foam board, fiberglass, or some other insulating material in the garage door panels. If this is not enough, then you might have to consider replacing the door. Most modern garage doors come already insulated.
Finally, it is a good idea to clean and lubricate the door tracks before winter comes, especially if you have a lot of leaves blown around your garage. The middle of winter is not when you want your garage door to get stuck halfway.
Winterizing your garage door can save on energy costs and make it easier to start your car on those frigid mornings.
