5. Build a Cardboard or Plywood Threshold to Block the Gap
For a more robust temporary solution, consider constructing a threshold using cardboard or plywood. Measure the width of the gap and cut a piece of cardboard or plywood to fit. Attach it to the floor directly in front of the garage door using heavy-duty tape or adhesive.
This makeshift threshold will help block drafts while providing a sturdier barrier than fabric alone. Remember, this is a temporary fix, so ensure that the materials you’re using can withstand moisture and temperature changes until professional repairs can be made.
6. Add Plastic Sheeting or a Tarp as an Interior Wind Break
Plastic sheeting or tarps can be used inside the garage as an additional windbreak. Hang the material from the ceiling to the floor, creating a secondary barrier behind the garage door. Use nails or adhesive hooks to secure the top edge and weights or tape to hold the bottom in place.
This method is particularly useful if your garage doubles as a workshop or storage area that needs to stay warmer. The plastic or tarp acts as an insulating layer, reducing airflow and keeping the interior space more comfortable.
7. Seal Side and Top Gaps With Painter’s Tape and Foam Strips
If your garage door has gaps along the sides or top, use painter’s tape and foam strips to create a temporary seal. Apply the foam strips along the edges of the door frame, pressing them tightly against the door when closed. Use painter’s tape to secure the foam in place and create an airtight seal.
This quick fix can help reduce drafts entering from the door’s perimeter. While not a permanent solution, it can significantly reduce airflow until more comprehensive repairs are possible.
