First measure the garage door

This is the first step you should take before installing weather stripping to seal the gaps on the sides of the door.

To measure the sides of the door, add the height of the door, after multiplying it by two, to its width. This will give you the drill length you need for this process.

When measuring, be sure to measure theSpace between the garage door and the frame.

When making the marks, be sure to leave an 8" gap from the inside of the rim. So pay attention to the measurements. This will help you complete the next step.

Many people tend to leave extra space at the bottom of the door just to let fresh air into the room. If you do the same, there is no point in closing the door tightly. When measuring, keep the following in mind:

  • Check the gaps on the sides and at the top of the door.

Check garage door jambs. If your stops aren't working properly, it's time to replace them, too. If not, you can move them closer to the door and see if they work better.

  • Check the suggestions

If the jambs look perfect but the door will not close vertically in a straight line, the roller tracks on both sides of the door may need to be checked. See if they keep the door at a constant distance. If not, loosen the screws to remove the rails and push them closer to the stops. However, don't go too far.

  • Examine the gaps along the bottom of the door.

A gap at the bottom of the door where the door meets the floor is very common. It happens for various reasons. The cause determines the solution to implement.

If your garage door won't close all the way, reset the limit switches. Do not use a flexible garage door seal. Even if you already have one installed, reset the limit switches so that the seal is compressed and animals cannot chew it.

Remove dirt and dust from the track with a brush

The next important process is the cleaning of doors, rails, etc. It is the backbone of the sealing process because any dirt or dust left behind can create an air pocket that will render all your efforts useless.

Use a brush and clean the rails. Make sure there is no dirt or dust. Clean the top, bottom, and sides of the garage door.

Gather everything you need for this process.

Make a list of the materials that will be needed for this process. It doesn't take much to seal the gaps on either side of a garage door. Therefore, you would have no problem finding them.

  • Purchase a tempo track of your choice. They are available in rolls. These days they usually come in a variety of styles.
  • Take a staple gun or pneumatic drill and a hammer.
  • Some nails or screws
  • Buy putty for the final touch.

Attach the garage door seal bracket to the bottom of the garage door

If the previously installed vinyl peel is still fine now, great. If you haven't installed anything before and find that your garage door bracket is faulty, it's time to replace it. First install an aluminum bracket. This will help you later to install a new stripper.

To remove the old caulk, do the following:

  • Take a flat screwdriver.
  • Remove the roll. So access the bottom seal of the garage door.
  • Now remove the previous stain.
  • Install the new aluminum bracket in its place.
  • Finally, use a screw gun to drill screws into the bottom or top of the mount.
