How to Fix Garage Doors That Are Drafty

Replacing the Bottom Stripping

• 1

  Open the garage door so the bottom edge is at a height you can reach. Place a pair of locking pliers on either track or prop the door up with a 2-by-4inch wood block.

• 2

  Grab one end of the weather stripping that's secured to the garage door’s bottom edge and slide it out if it's in a track. Use a hammer and pry bar to remove it if it's nailed on to the door.

• 3

  Slide the new weather stripping into one end of the track. Slide it across the door’s bottom until you reach the other end, or hold one end of the weather stripping onto the edge of the door bottom. Nail it in place. Continue lining up the remainder of the stripping and nail it into place. Trim excess weather stripping with a utility knife or a pair of sharp scissors.

Seal the Sides

• 4

  Remove the pliers or the 2-by-4-inch wood block and completely close the door. Measure one side of the garage door’s frame from the top to the floor. Cut a piece of weather stripping with a utility knife or sharp scissors to that length.

• 5

  Place the weather stripping flat on the side frame so it's snug against the garage door. The thicker side should face the driveway. Nail the piece into place from the top, all the way down to the bottom end.

  Repeating this step with the other side of the garage door frame seals it from drafts.
