Understanding Garage Door Springs: Types, Lifespan, and When to Replace
2024-01-08 10 min read
Garage door springs are the unsung heroes of your garage door system. They do the heavy lifting.literally.counterbalancing the weight of your door so the opener motor doesn't have to work as hard. Understanding how springs work, their lifespan, and when they need replacement can save you from unexpected breakdowns and potential safety hazards.
The Two Types of Garage Door Springs
Torsion Springs
Torsion springs are mounted horizontally above the garage door opening, attached to a metal shaft. When the door closes, the springs wind up and store energy. When the door opens, they unwind and release that stored energy, helping to lift the heavy door.
Advantages of torsion springs: - Longer lifespan (typically 15,000-20,000 cycles) - Smoother, more controlled door operation, Better balance and less strain on the opener, Safer design.if a spring breaks, it stays on the shaft
Most modern residential garage doors use torsion springs because of their superior performance and safety features.
Extension Springs
Extension springs are mounted on either side of the door, running parallel to the horizontal tracks. They stretch and contract as the door opens and closes. You'll find extension springs on older garage doors and some single-car garage installations.
Characteristics of extension springs: - Shorter lifespan (typically 10,000 cycles) - Less expensive to purchase, Potential safety hazard if not equipped with safety cables, More prone to uneven wear if not properly matched
If your garage door uses extension springs without safety cables, we strongly recommend having cables installed. If a spring breaks without safety cables, it can become a dangerous projectile.
How Long Do Garage Door Springs Last?
Garage door springs are rated by cycles, with one cycle being one complete open and close of the door. The average household opens and closes their garage door 3-5 times per day.
Standard Torsion Springs (10,000 cycles): - At 4 cycles/day: approximately 7 years, At 2 cycles/day: approximately 14 years
High-Cycle Torsion Springs (25,000-50,000 cycles): - At 4 cycles/day: 17-34 years, At 2 cycles/day: 34-68 years
Extension Springs (10,000 cycles): - At 4 cycles/day: approximately 7 years, At 2 cycles/day: approximately 14 years
Environmental factors also affect spring lifespan. Humidity, temperature extremes, and lack of maintenance can shorten the life of your springs. Regular lubrication helps reduce friction and extend spring life.
Warning Signs Your Springs Need Replacement
1. Visible Gaps in the Spring
The most obvious sign of a broken spring is a visible gap in the coil. When a torsion spring breaks, it typically separates into two pieces with a noticeable gap. If you see this, do not attempt to operate the door.
2. Door Won't Open or Opens Only Partially
If your garage door opener is straining to lift the door or the door only opens a few inches before stopping, the springs may be broken or losing tension. The opener is designed to work with functional springs.without them, it doesn't have enough power to lift the door safely.
3. Loud Bang from the Garage
A breaking garage door spring makes a loud bang, similar to a gunshot or firecracker. If you heard a loud noise from your garage and can't identify the source, check your springs for damage.
4. Door Falls Quickly When Closing
When springs are working properly, they control the door's descent, allowing it to close smoothly and relatively slowly. If your door falls rapidly when closing, the springs may be broken or losing tension.
5. Door Is Crooked or Uneven
If one spring is broken or weaker than the other, the door may appear crooked when opening or closing. This puts stress on the remaining spring and can damage other components if not addressed quickly.
6. Cables Are Loose or Frayed
When springs break, the cables that work with them may become loose or tangled. Visible cable damage often indicates a spring problem.
Why Spring Replacement Is a Job for Professionals
We cannot stress this enough: garage door spring replacement is dangerous. Each spring can hold 300+ pounds of tension. Improper handling can result in serious injury or death.
