Cold air pours in under the garage door and the repair company can’t come until after New Year. What can I do now?

6. Check for Snow, Ice, or Debris

Sometimes the seal isn’t broken—it’s blocked:

• Clear snow, ice, or dirt from the door’s bottom edge
• Make sure the door closes fully
• Even small obstructions can cause big drafts

7. Avoid Risky Heat Sources

It can be tempting to use space heaters in the garage, but this can be unsafe—especially near flammable materials. Focus on blocking the cold, not heating the garage directly.
