Why a Broken Spring Is Dangerous — Not Just Inconvenient

Garage door springs are wound under extremely high tension to counterbalance the door’s weight. That same tension makes a broken spring genuinely hazardous. Never attempt to open, close, or force a garage door with a broken spring — the door can drop unexpectedly, and the sudden release of tension in a spring or cable can cause serious injury. This isn’t a repair to attempt yourself; it requires the right tools and training to handle safely.

What Causes Garage Door Springs to Break?

Garage door springs are rated for a certain number of open-close cycles — typically somewhere in the 10,000–15,000 range — and will eventually wear out from normal use. A few other factors can shorten that lifespan:

• Age and accumulated cycle count
• Rust or corrosion from moisture exposure
• Lack of routine lubrication and maintenance
• Extreme temperature swings, which are common through Kansas City metro winters and summers
• A spring that was undersized for the door’s weight during a previous installation

Torsion Springs vs. Extension Springs

Most garage doors use one of two spring systems. Torsion springs mount horizontally above the door and twist to create lifting force — these are the more common setup on newer doors. Extension springs run along the horizontal tracks on either side of the door and stretch to provide tension. Both fail in similar ways, but the repair process differs. Our garage door spring repair page covers the replacement process for both types in more detail.

What to Do If You Think Your Spring Is Broken

1. Don’t try to open or close the door. Leave it in whatever position it’s in.
2. Don’t use the automatic opener. Forcing it can damage the opener motor and creates a safety risk.
3. Keep kids and pets away from the door until it’s been inspected.
4. Call a professional. Spring replacement involves high-tension components that require the right tools and experience to handle safely.

Frequently Asked Questions

How long do garage door springs last?

Most springs are rated for 10,000–15,000 cycles (one cycle = one full open and close). For an average household, that generally works out to several years, though frequency of use and maintenance affect the timeline.

Can I open my garage door manually if the spring is broken?

We recommend against it. Without spring tension, the door is very heavy and can drop suddenly. If you need vehicle access before a technician arrives, use extreme caution and keep everyone clear of the door’s path.

How much does it cost to replace a garage door spring?

Cost depends on the type of spring, your door’s size and weight, and whether one or both springs need replacement. Contact us for a straightforward quote before any work begins.

Should I replace one spring or both?

If your door has two springs and one has broken, we generally recommend replacing both, since they wear at a similar rate and the second is often close behind.
