Why does my garage door not want to close when it’s cold?

Answered by Robert Dupre

The most common issue with garage doors in the winter is difficulty in closing. This frustrating problem is often caused by the contraction of metal due to cold temperatures. When the temperature drops, the metal components of your garage door, such as tracks, hinges, and springs, start to tighten and become less flexible. This can make it challenging for the door to move smoothly along its tracks and ultimately prevent it from closing properly.

One of the main reasons for this contraction is the basic principle of physics that states that cold temperatures cause materials to shrink or contract. Metal is particularly susceptible to this phenomenon. As the surrounding air gets colder, the metal in your garage door reacts by tightening and becoming more rigid. This can result in increased friction and resistance when trying to close the door.

Additionally, the lubricants and oils used in garage door mechanisms can also be affected by cold temperatures. In colder weather, these lubricants can become thicker and less effective, further impeding the movement of the door. This combination of contracted metal and thickened lubricants creates a perfect storm for garage door troubles in the winter.

It is worth noting that the severity of this issue can vary depending on factors such as the design and quality of your garage door, the age of the components, and the specific climate in your area. In colder regions, where temperatures regularly drop below freezing, this problem may be more pronounced.

To address this issue and ensure that your garage door closes smoothly during the winter, there are a few steps you can take:

1. Lubricate the moving parts: Apply a high-quality garage door lubricant to the tracks, hinges, and springs. This will help to reduce friction and ensure that the door moves more easily. Be sure to use a lubricant specifically designed for garage doors, as general-purpose oils or greases may not be as effective in extreme temperatures.

2. Check and adjust the door’s alignment: Cold temperatures can sometimes cause a garage door to become misaligned. Inspect the tracks and ensure they are properly aligned and free from any debris or obstructions. Use a level to check if the tracks are straight and make any necessary adjustments to ensure smooth movement.

3. Insulate the garage: Adding insulation to your garage can help to regulate the temperature and reduce the impact of cold weather on your garage door. Insulation can also help to prevent drafts and reduce energy loss.

4. Install a garage door seal: A seal or weatherstripping at the bottom of the garage door can help to create a barrier against cold air and moisture. This can also improve the overall energy efficiency of your garage.

5. Regular maintenance: It’s important to regularly maintain your garage door throughout the year, but especially in the winter. Inspect the door for any signs of wear or damage and address them promptly. Clean the tracks and remove any debris or ice that may be hindering the door’s movement.

The contraction of metal in cold temperatures is the primary reason for garage doors struggling to close in the winter. By understanding this phenomenon and taking proactive measures to address it, you can ensure that your garage door functions properly throughout the colder months. Regular maintenance and proper lubrication are key to keeping your garage door operating smoothly in all weather conditions.
