How to Winterize Your Garage Door (NJ Homeowner's Guide)

Get Your Garage Door Winter-Ready

NJ winters bring freezing temps, ice, snow, and salt that damage your garage door system. Prep now prevents expensive emergency repairs in January.

1. Replace Weatherstripping

If bottom seal is brittle or cracked, replace before the first freeze. $20–$40, 15 minutes to install.

2. Lubricate Moving Parts

Apply silicone-based lubricant (NOT WD-40) to hinges, rollers, springs, and bearing plates.

3. Check Door Balance

Disconnect opener, lift door to waist height. If it moves on its own, springs need adjustment by a pro.

4. Inspect Springs and Cables

Look for rust, fraying, gaps between coils. Cold makes metal brittle — catch problems now.

5. Test Auto-Reverse

Place 2x4 in door path. Door should reverse on contact. If not, sensors need repair.

6. Clear the Tracks

Remove dirt, leaves, debris. Salt and grit accumulate faster in winter.

7. Consider Insulation

Insulated doors reduce heat loss by up to 71% and keep your car warmer.
