All garage door springs play a vital role in safely lifting, lowering, and balancing your garage door—whether it's lightweight, heavy-duty, designed for a standard lift, or high-lift system. The springs act as powerful counterbalances, making it possible to open and close your door smoothly with minimal effort.
Types ofGarage Door Springs: Extension vs. Torsion
- Extension Springs: Extension springs are typically mounted on either side of the door and stretch (extend) when the door is closed. As you open the door, they contract and release stored energy, which helps raise the door. They’re usually installed in pairs to ensure balanced tension and safe operation. For heavier doors, additional extension springs may be used.
- Torsion Springs: Mounted above the garage door opening, torsion springs don't stretch—instead, they wind and unwind around a shaft. When you close the door, the springs wind up, storing energy. As you open the door, the springs unwind, releasing that energy to lift the door. Torsion springs come in left-wind and right-wind configurations, which provide balanced torque and ensure the smooth, safe movement of your garage door.
Key Differences and How They Work
- Extension springs rely on stretching action and are typically installed parallel to the horizontal tracks.
- Torsion springs depend on rotational force (torque) and are mounted horizontally above the door.
- The right configuration depends on your door’s weight, size, and movement style (up-and-over, roll-up, sectional).
How to Know Which Type You Have
- If you see coils running along the sides of your garage door’s horizontal tracks, you have extension springs.
- If there’s a bar running above the door with tightly wound coils, this system uses torsion springs.
Why Spring Maintenance is Critical
Worn or improperly balanced springs can cause:
- Excessive noise
- Uneven lifting or closing
- The door to slam or fail to stay open
Regular professional maintenance is crucial since springs are under extreme tension and can be dangerous if handled improperly.
Pro Tip: Signs You Need Garage Door Spring Service
- The garage door feels extremely heavy
- The opener has trouble lifting the door
- Loud popping, banging, or snapping noises
- Visible gaps, rust, or stretching in the springs
If you notice any of these warning signs, it’s time to call a professional immediately.
