New Hampshire winters are brutal on garage doors. Temperature fluctuations, ice, and snow can cause metal to contract, lubricants to thicken, and weatherstripping to crack. Proper preparation prevents costly repairs and keeps your garage—and home—warm and secure.
The rubber seal at the bottom of your door is your first defense against the cold:
- Look for cracks, gaps, or brittleness - Replace if damaged—this is an easy DIY project - Consider upgrading to cold-rated weatherstripping
Cold weather increases stress on these components:
- Look for signs of rust or corrosion - Check cables for fraying - Never attempt to adjust springs yourself—call a professional
A balanced door is crucial for cold weather operation:
1. Disconnect the opener 2. Manually lift the door halfway 3. It should stay in place—if it falls, springs need adjustment
Cold weather makes lubricants thicken and fail. Use the right products:
- Do use: Silicone-based lubricants (won't freeze) - Don't use: WD-40 or petroleum-based products - Apply to: Rollers, hinges, springs, and tracks
An insulated garage door can:
- Reduce heating costs by up to 20% - Protect your car and stored items - Prevent freeze-thaw damage

- Keep salt/sand away from the door bottom (causes corrosion) - Clear snow and ice from the threshold before operating - If door freezes shut, don't force it—apply heat carefully
