The rubber weatherstripping along the bottom of the door helps keep out the cold as well as water, dust, and dirt. Check it twice a year to make sure it is in good shape. Some weatherstripping fits into the bottom of the door using a flange that slides into a groove in the bottom of the door. Weatherstripping for wooden garage doors is usually nailed in place. Garage door weatherstripping is sold by the foot or in large rolls at hardware stores and big-box home improvement stores.
If your door has weatherstripping along the sides, also check its condition and reattach any loose spots or replace the entire length of stripping if it is badly worn or damaged.
