While Southern California winters are milder than most of the country, temperature fluctuations and occasional cold snaps can still affect your garage door's performance. Taking time to prepare your garage door for winter can prevent inconvenient breakdowns and extend the life of your door and opener.
This guide covers everything you need to do to winterize your garage door and keep it operating smoothly throughout the colder months.
Weatherstripping is your first line of defense against cold air, rain, and pests entering your garage. Over time, weatherstripping can become brittle, cracked, or compressed, reducing its effectiveness.
The bottom seal (or astragal) runs along the bottom of your garage door and creates a barrier between the door and the garage floor. Inspect it for cracks, gaps, or areas where it's pulling away from the door. Replace if necessary, it's an inexpensive part that makes a significant difference in energy efficiency.
Check the weatherstripping on the sides and top of your door frame. These should create a tight seal when the door is closed. Replace any sections that are damaged or no longer making good contact with the door.
Cold temperatures can cause lubricants to thicken, making your garage door operate less smoothly. Apply a silicone-based lubricant or white lithium grease to these components:
Apply lubricant to each hinge pivot point and roller stem. This reduces friction and wear while preventing squeaking.
Lightly coat your torsion springs with lubricant. This prevents rust and helps maintain their flexibility in cold weather.
While you shouldn't apply heavy lubricant to your tracks (it can attract dust and debris), a light coating of lubricant can help prevent rust and ensure smooth operation.
If your garage door has a manual lock, lubricate it to prevent it from sticking in cold weather.
A properly balanced garage door puts less strain on your opener and is less likely to have problems in cold weather.
1. Disconnect the opener by pulling the manual release cord 2. Manually lift the door to about waist height 3. Let go, the door should stay in place with minimal movement 4. If the door falls or rises, the springs need adjustment
Have a professional adjust your springs if the door fails the balance test. Properly balanced springs will last longer and reduce stress on your opener.
With the opener connected, open and close the door several times while observing:
- Is the motion smooth and consistent? - Does the door hesitate at any point? - Are there any unusual sounds? - Does the door close completely to the floor?
Address any issues before cold weather arrives.
Cold weather can affect the performance of your safety features, so it's important to verify they're working correctly.
Clean the lenses of your photo-eye sensors with a soft cloth. Dust, cobwebs, or condensation can interfere with the beam. Test the sensors by waving an object through the beam while the door is closing, the door should stop and reverse immediately.
Test the mechanical auto-reverse by placing a 2x4 flat on the ground in the door's path. When the door contacts the board, it should reverse within two seconds.
If your garage is attached to your home, proper insulation can reduce your heating bills and keep your garage at a more comfortable temperature.
If your garage door isn't insulated, consider upgrading to an insulated model or adding an insulation kit to your existing door. Insulated doors help regulate temperature and also operate more quietly.
Don't forget about the walls and ceiling of your garage, especially if you have living space above. Proper insulation in these areas can significantly impact your home's energy efficiency.
If you have a battery backup on your opener, cold weather can reduce battery performance. Check your battery according to the manufacturer's recommendations and replace if necessary. A fully charged battery backup ensures your garage door will operate during winter power outages.
