Garage doors usually have a U-shaped weatherstrip, which works for most flooring materials. Look closely at the weatherstripping to check for the extent of gaps above the garage door.
Seeing signs of cracking or breaking apart only means you have to replace it, especially before the weather gets really cold or before the rainy weather begins.
How To Replace The Weather Stripping
One of the most common reasons why there are gaps above the garage door is that the weather stripping needs to be replaced. You can do the replacement job yourself.
These simple and easy steps can fill the gaps above and around the garage door:
- Carefully remove the existing weather stripping using a hammer and pry bar.
- Remove all the nails and screws from around the door frame.
- Remove all residual debris to see if there are damages in the door frame.
- Measure the perimeter of the garage door using a tape measure.
- Cut strips of vinyl according to the shape and measurement of the garage door.
- Install new weather stripping at the top section of the garage door. Make sure the nails are spaced some 8 to 18 inches apart.
- Install new weather stripping at the sides of the garage door. Make sure the pieces overlap with the top section to ensure a closed seal.
- Cut off the excess pieces of vinyl strips to make sure the sizes are exact with the garage door's measurement.
- Apply caulk to seal the joints and make sure there are no spaces in between the weather stripping.

Cracks or bumps in the floor can create gaps or spaces around the garage door, but fortunately, a U-shaped weather stripping works just as well on uneven surfaces. It works even if the garage floor is uneven or has cracks.

To adjust the garage door opener, you have to adjust the screws, and by turning it clockwise, you increase its strength to make sure it closes firmly. Just check on the manual to ensure the garage door works efficiently.
There should be no gaps at the top, bottom, or sides of the garage door, which is important both for privacy and protection.
Make sure the garage door opener is working properly, with no chain tension or vibration. If it's otherwise, try adjusting the chain sag on the slack side. The chain should not be too loose or too tight but just enough not to cause chain vibration.
