Garage door springs play a vital role in the smooth functioning and longevity of your garage door. Understanding how these springs work and implementing proper maintenance practices can help you avoid costly repairs and ensure the safety of your family and belongings. In this blog post, we will delve into the world of garage door springs, exploring their types, functionality, and essential maintenance tips.

Types of Garage Door Springs:

Garage doors typically use two types of springs: torsion springs and extension springs.

  • Torsion Springs: Torsion springs are mounted horizontally above the door opening. They work by twisting or rotating to generate torque, which helps lift and lower the garage door smoothly. Torsion springs are known for their durability and ability to handle heavy garage doors.
  • Extension Springs: Extension springs are typically found alongside the horizontal tracks on either side of the garage door. They extend and contract to counterbalance the door’s weight during opening and closing. These springs are suitable for lighter garage doors.

How Garage Door Springs Work

Both torsion and extension springs operate on the principle of storing and releasing mechanical energy.

  • Torsion Springs: When the garage door is closed, torsion springs are under immense tension. As the door is opened, the stored energy in the springs unwinds, applying torque to the shaft, which helps lift the door. When closing, the springs wind up again, storing energy for the next cycle.
  • Extension Springs: Extension springs stretch and contract as the garage door is operated. When the door is closed, these springs are in a stretched position, storing energy. As the door is opened, the stored energy is released, assisting in the upward movement. When closing, the springs stretch again, storing energy for the next operation.

Importance of Maintenance

Regular maintenance of garage door springs is crucial for their optimal performance and longevity. Neglecting maintenance can lead to premature wear, potential damage to the door opener, and even safety hazards. Here are some essential maintenance tips:

  • Visual Inspection: Perform a visual inspection of the springs, looking for signs of wear, rust, or damage. If you notice any issues, such as gaps in the coils, significant corrosion, or a broken spring, it’s vital to call a professional for repairs.
  • Lubrication: Apply a high-quality silicone-based lubricant to the springs, hinges, rollers, and tracks regularly. This helps reduce friction and ensures smooth operation. Avoid using petroleum-based lubricants as they can attract dirt and grime.
  • Balance Testing: Disconnect the garage door opener and manually operate the door halfway. If it remains in place, the springs are adequately balanced. If the door falls or rises, it indicates an imbalance and calls for professional adjustment.
  • Professional Inspection: Schedule a professional inspection at least once a year. Garage door technicians have the expertise to identify potential problems, adjust tension, and replace worn-out springs, ensuring optimal performance and safety.


Garage door springs are vital components that enable the smooth and safe operation of your garage door. Understanding the different types of springs, their functionality, and implementing regular maintenance practices are key to extending their lifespan and minimizing the risk of accidents or costly repairs. By following the maintenance tips outlined in this guide and seeking professional assistance when needed, you can keep your garage door springs in top shape, ensuring the security and convenience of your home.
