1. Seal Garage Door Bottom
You can seal the garage door bottom in two ways, i.e., by a threshold seal and a bottom seal.
You can use a threshold seal to seal the garage door’s bottom portion. But for this, you need a few tools like
- A measuring tape
- Hacksaw or knife
You need to clean the garage properly and remove all the dust and debris and then try to install the threshold seal. The seal comprises rubber or vinyl and is extremely useful in preventing rainwater and strong wind from blowing inside the garage. But cleaning the threshold seal may create an issue in removing the debris outside the garage door.The threshold seal is fixed just beneath the garage door, i.e., on the ground, by an adhesive so that it will last longer.
You can even combine the threshold seal with the bottom seal to seal your garage door.The installation of this seal is quite simple and requires minimal effort. Let’s discuss the steps below.
- Your first step will be to take a measuring tape and measure the distance between the garage door rivets.
- Take a knife or hacksaw and cut the threshold seal according to the measurement you have taken above.
- Now place the cut portion of the seal on the ground, i.e., between the garage door rivets.
- Noe closes the garage door and pushes the seal so that it will remain just beneath the garage door.
- Take a pencil and mark along the two sides of the threshold seal.
- Your next step will be to clean the marked areas. Take sandpaper and rub it on the marked areas to remove any dust.
- Next, take a vacuum cleaner and remove any possible dust and dirt.
- You can take wine spirit and cloth and remove the leftover grease and dirt from the marked areas.
- Apply the adhesive or glue on the marked areas.
- Apply the glue in a zigzag pattern in between the pencil lines. Try to apply the glue quickly; otherwise, it may dry out, and you cannot properly seal the garage door.
- Take the threshold seal you cut earlier and lay it on where you have applied glue. Use your hands and press the seal to attach it firmly to the ground.
- If glue leaks, take wine spirit and a cloth to wipe the excess glue.
- Now close the garage door and check the seal. If you have done it correctly, no light will seep inside the garage door.
- Your first duty will be to remove the old bottom seal if applied.
- The seals usually crack with time. So, remove the screws holding the seal and pull them off.
- Fold the bottom seal so that T shape edges will face upward.

- Now open the packing of the double-sided tape and install it on the I beam. You can then attach the next seal after the first seal. You need to attach the second seal so that the brush of the second seal will tuck in the track of the first seal. Attach the third seal accordingly. Continue to spread the seal until it completely covers the I-beam of the garage.
- You need to be a bit careful while adding the last seal. Use a measuring tape and measure the distance covered by the third seal.
