Step-by-Step Processes for How to Winterize a Garage Door

Step 1: Inspect the Door

Inspect the door and its components to identify any potential issues. Make sure that all nuts, bolts, screws, pulleys, rollers, and springs are secure and in good condition. Remove dirt and debris from the door using a damp cloth or brush. Wipe down tracks with a slightly lubricated cloth to remove any dust and dirt.

Step 2: Lubricate Moving Parts

Apply lubricant to the door’s moving parts, including the rollers, springs, pulleys, hinges, and tracks. This will help ensure that the door works smoothly when opened and closed. Apply a sealant or weatherproofing to the door’s exterior trim. This will help protect the wood from extreme weather conditions and moisture buildup.

Inspect the door’s weatherstripping for any gaps or worn-out areas, and replace it as needed. This will help prevent cold air from entering the garage during colder months.

Step 4: Install a Threshold Seal

Add a sealant or weatherstrip to the threshold of the door. This will help prevent cold air from entering and keep warm air inside. Attach a door sweep to the bottom of the door. This will help keep cold drafts from entering through gaps at the bottom of the door.

Step 5: Replace Weatherstripping

Replace old, worn-out weatherstripping with new weatherstripping that is specifically designed to withstand extreme temperatures. This will provide an extra layer of protection against cold drafts. Test your newly winterized garage door to make sure there are no issues. Open and close the door several times to ensure proper operation. If you find any issues, contact a professional as soon as possible for repairs or adjustments.
