Turn on a heat gun or hair dryer, and aim it at the ice fusing the garage door to the cement. Spread the heat evenly along the bottom of the garage door, giving the ice time to soften. Spray a chemical de-icer in the gap between the door and cement.
Use a chisel, screwdriver or the tip of a shovel to gouge out the softer ice. Wait until the ice is soft before gouging so you don't damage the seal at the bottom of the door. Chip away all the ice along the bottom before attempting to open the garage.
Once the garage door opens, examine the ground for snow, ice or water. To prevent the garage door from freezing again, use the heat gun or hair dryer to clear away any source of moisture.
