While contemplating where to start, the first place on your list should be the bottom part of your garage door. Check if any light ray is coming through it when the door is shut off. If you see lights coming in, it has holes that you can seal immediately using the floor seals.


  • Take a cloth piece and clean all the debris and dirt from the garage floor and the door.
  • Cut the seal according to the door area.
  • Put the seal under the door with the protection cover. The rubber part should be under the door. Mark the place that needs to be sealed.
  • After applying the seal let it rest for 24 hours.

2. Using Bottom Seal

You can block the garage door with some long-lasting garage bottom seal. These products have clips with them to make the installation process easy. Just clip them where you need them, and nothing else is required. This type of seal keeps dirt or rodents from infiltrating your garage.


  • Calculate the size of the door bottom.
  • Cut the seal measuring the same size.
  • Use clips to attach the seals to the garage door.

5. Using Threshold Seal

If you have a driveway slope, using a threshold seal is a great idea for sealing a garage door. This one is just like the bottom seal except for the fixture part. Rather than the door, a threshold seal is connected to the floor. This sturdy and durable product contains its own adhesive, meaning you don’t need to buy it separately.

  • Cut the threshold seal according to the taken measurement.
  • Remove any dirt from the floor and wipe it using a clean cloth.
