How to replace the seals on your sliding glass doors.

Begin the fix by cleaning the bottom door track. Insert the caulking tube into the caulk gun and push the plunger into the back of the tube and turn it 180 degrees. Attach the new seals to the sliding door in one continuous piece or according to the directions on the package. Press the release button.

Add between 5 and 10 percent to this measurement to get the amount of weatherstrip you will need to complete the project. Use the adjusting screws at the bottom of the metal door frame to raise or lower the rollers. Cut the tip of the nozzle of a tube of silicone caulking at a 45 degree angle and poke the foil at the bottom of the tube with the metal rod connected to the caulk gun. Be sure to remove debris big and small to ensure a smooth slide.

Place the door back on the track and tilt up. Move the door in until it is within a half inch of the latch side jamb. Sealing the exterior of a sliding glass door only requires a few minutes of your time but it prevents excessive drafts from entering your home saving money on heating bills throughout the winter. These will be covered in plugs the same color as your door.

Look at the weatherstripping along the sides of the sliding section of door where it meets the door frame as well as the bottom of the door. Seal the exterior of a sliding glass door to prevent drafts. Determine which weatherstripping you need to replace.
