To install weatherstripping on a garage door, clean the door's surface, measure the door, cut the weatherstripping to size, and attach it along the bottom and sides to create a tight seal.

Installing weatherstripping helps keep out drafts, moisture, and pests. By cutting the weatherstripping to the correct size and securing it along the edges of the door, you can improve the insulation of the garage and protect it from external elements. Regularly replacing worn weatherstripping also helps maintain the seal.
