Winter weather can be harsh on garage doors. Proper weatherproofing protects against cold, moisture, and energy loss.
Replace Weather Stripping
Weather stripping seals gaps around the door perimeter.
Signs of wear: Cracks, brittleness, visible gaps, cold drafts
Types:
- Vinyl: Most affordable, lasts 1-2 years
- Rubber: Better durability, 3-5 years
- Bulb seal: Best for uneven floors
Install/Replace Bottom Seal
The bottom seal (threshold or astragal) prevents water, snow, and drafts from entering under the door.
Installation tips:
- Clean the area thoroughly first
- Measure accurately – order slightly longer
- Slide into retainer or attach with adhesive
- Ensure even contact with floor
Lubricate Moving Parts
Cold weather thickens lubricants. Use silicone-based or lithium grease rated for low temperatures.
Lubricate these components:
- Hinges
- Rollers
- Springs (torsion bar)
- Bearing plates
- Lock mechanism
Check Insulation
Inspect existing insulation for gaps or damage. Add insulation if R-value is inadequate for your climate.
Test Door Balance
Cold weather affects spring tension. A poorly balanced door strains the opener motor.
Test: Disconnect opener and manually lift door halfway. It should stay in place. If it falls or rises, springs need adjustment.
Clear Drainage
Ensure water can drain away from the door. Poor drainage leads to ice buildup that can damage the door or prevent operation.
Protect from Ice
- Never force a frozen door open
- Use de-icer on threshold, not salt (corrodes metal)
- Keep snow cleared from door base
- Run door periodically during extreme cold
Winter Emergency Kit
Keep these items handy:
- Silicone spray lubricant
- Ice scraper
- De-icer
- Emergency release instructions
- Garage door company phone number
