Garage Door Spring Safety: What Every Homeowner Should Know
2024-01-05 5 min read
Garage door springs are under tremendous tension—enough to lift a door weighing 200-400 pounds or more. While this stored energy makes operation effortless, it also makes springs one of the most dangerous components in your home to handle without proper training and equipment.
Understanding How Garage Door Springs Work
There are two main types of garage door springs:
Torsion Springs
Located above the door opening, torsion springs wind and unwind on a shaft to raise and lower the door. They're the more common type in modern installations because they're safer, more durable, and provide smoother operation. A typical residential door has one or two torsion springs.
Extension Springs
Found on either side of the door, running parallel to the horizontal tracks, extension springs stretch and contract as the door moves. They're more common on older doors and lighter-weight models. Because they're under tension even when the door is closed, they require safety cables to prevent them from becoming projectiles if they break.
Why Springs Are Dangerous
The numbers tell the story. A broken torsion spring releases enough force to cause serious injury or death. The spring can whip around violently, and the sudden release of tension can cause the door to drop without warning.
Even attempting to adjust spring tension without proper tools and knowledge is extremely dangerous. Professional technicians use specialized winding bars, safety equipment, and techniques developed over years of training and experience.
Warning Signs Your Springs Need Attention
Learn to recognize these indicators that your springs may be wearing out or damaged:
Visible Wear: Look for gaps in the coils, rust, or stretched sections. Healthy springs should have evenly spaced coils with no signs of deformation.
Difficulty Opening: If your door feels unusually heavy when opened manually, the springs may be losing tension. A properly balanced door should stay in place when opened halfway—if it falls or rises on its own, the spring tension needs adjustment.
Loud Bang from Garage: This is often the sound of a spring breaking. The door may still work if you have two springs and only one broke, but operating it puts tremendous stress on the remaining spring and opener.
Jerky Operation: Springs that are wearing unevenly can cause the door to jerk or shake during operation.
Gap in Spring Coils: A visible gap in your torsion spring means it has broken and needs immediate replacement.
What to Do When a Spring Breaks
1. Don't try to operate the door: Even if it still moves, doing so can cause further damage or injury 2. Disconnect the opener: Pull the emergency release cord to prevent the opener from trying to lift the full weight of the door 3. Keep the door closed if possible: An open door with broken springs can fall without warning 4. Call a professional: This is not a DIY repair under any circumstances 5. Keep people and pets away: Until the door is repaired, treat it as a hazard zone
The Lifespan of Garage Door Springs
Standard garage door springs are rated for about 10,000 cycles—one cycle equals one open and close. For a family that opens their garage door four times daily, that's roughly 7-9 years of life.
High-cycle springs rated for 25,000-100,000 cycles are available and worth considering if you use your garage frequently or want to minimize future service calls.
