Cold Air Pouring Under Your Garage Door? Quick Fixes Until the Repair Company Arrives
Keep your garage warm and prevent drafts with simple, DIY solutions for cold air under the garage door until the repair company can come.
Nothing makes a winter morning worse than cold air rushing in under your garage door. If your repair company isn’t coming until after the New Year, don’t worry — there are practical, temporary fixes you can do today to keep your garage (and home) warmer.
1. Identify the Source of the Draft
Before you fix it, understand where the cold is coming from:
-
Bottom seal/gasket: Most garage doors have a rubber strip that wears out or cracks.
-
Gaps on the sides: Air can sneak in through worn weatherstripping along the tracks.
-
Uneven door alignment: If the door isn’t level, the seal won’t make full contact with the floor.
Pinpointing the problem helps you choose the most effective temporary solution.
2. Temporary DIY Solutions
A. Use a Garage Door Draft Stopper
-
Roll up a foam, fabric, or even a pool noodle and place it along the bottom of the door.
-
Slide it under the door when closed to block cold air.
B. Apply Weatherstripping Tape
-
Adhesive weatherstripping can seal gaps along the sides or bottom of the door.
-
Look for temporary, removable tape to avoid damaging the door before professional repairs.
C. Lay a Heavy Towel or Blanket
-
For a quick, short-term fix, fold a thick blanket or towel and tuck it under the door.
-
Works best overnight or during the coldest parts of the day.
D. Block the Garage from Your Home
-
Close interior doors between your garage and living space.
-
Add a door draft stopper at the entrance to reduce cold air from reaching your home.
E. Insulate the Garage Floor (Optional)
-
If the garage floor feels icy, temporary foam mats or rugs can help keep the space warmer.
3. Reduce Heat Loss Further
-
Seal other gaps: Windows, vents, and small cracks in the walls can let in cold air.
-
Use a space heater safely: If you need extra warmth, place a portable heater safely away from flammable items.
-
Add insulation panels: Temporary foam board insulation can reduce overall heat loss in the garage.
Combining multiple fixes is often more effective than relying on one method.
Real-Life Scenario
Homeowner Mike shares:
“Our garage door seal tore right before the holidays, and the repair company couldn’t come until January. I rolled a pool noodle under the door and added weatherstripping tape along the sides. It stopped most of the draft, and I was able to park my car without scraping frost off it every morning!”
FAQs
1. Can I just leave the garage door closed?
Yes, but if there’s a big gap at the bottom, cold air can still enter and chill your home.
2. Are DIY solutions safe for the door?
Yes — foam, blankets, and removable weatherstripping are safe temporary measures. Avoid anything that can jam the door mechanism.
3. How long can I leave a draft stopper in place?
For as long as needed until the repair. Just check for moisture buildup if using towels or blankets.
4. Can I prevent future drafts?
Regularly inspect seals and weatherstripping, and replace worn parts before winter hits.
5. Will these fixes keep pests out?
Partially — sealing gaps helps, but larger pest problems may need professional attention.
Even if your garage repair company can’t come until after the New Year, you don’t have to suffer from icy drafts.
