What is the average life of a garage door spring?

The average life of a garage door spring system is typically 7-9 years, if the spring set was calculated for 10,000 cycles based on being used 4 times per day.

Since the garage door is being used more like a front door by most busy families, the springs may only last between 4-6 years, or even less. 

There are two types of spring systems: Extension springs and Torsion Springs.

Extension springs are typically used for small, lightweight non-insulated doors.

Torsion springs are the preferred spring system, since they are safer and provide a smoother operation. In addition, a torsion spring system allows for engineering a high cycle count. Through a mathematical equation, the spring life can usually be doubled to 20,000 cycles, ensuring a longer time period of use without failure.
