Garage door springs are the unsung heroes of your garage door system. They bear the tremendous weight of your door, making it possible to lift a door weighing several hundred pounds with minimal effort. When springs fail, your garage door becomes inoperable, and attempting to fix them yourself can be extremely dangerous. Here's everything you need to know about garage door springs.
Your garage door springs counterbalance the weight of the door, making it feel much lighter than it actually is. A typical two-car garage door weighs 200-400 pounds, yet you can lift it with one hand when the springs are properly balanced. This is possible because the springs store mechanical energy when the door closes and release it when the door opens.
There are two main types of garage door springs, and the type you have affects replacement cost, lifespan, and safety considerations.
Torsion springs mount horizontally above the garage door opening. They work by twisting (applying torque) when the door closes, storing energy that helps lift the door when opening. Torsion springs are:
- More durable, typically lasting 15,000-20,000 cycles, Safer, as they're contained on a shaft and don't fly off when they break, More expensive to replace, Better at providing smooth, balanced operation, Standard on most modern residential doors
Extension springs mount on either side of the door, parallel to the horizontal tracks. They stretch when the door closes and contract when opening. Extension springs:
- Are less expensive initially, Have shorter lifespans (around 10,000 cycles) - Can be more dangerous if they break without safety cables, May cause uneven door movement as they age, Are more common on older installations
Recognizing failing springs before they break completely can save you from being stranded with an inoperable door. Watch for these warning signs:
If your door feels heavier than usual or your opener struggles more than it used to, the springs may be losing tension.
Torsion springs develop visible gaps between coils when they break. Even small gaps indicate the spring has failed.
A door that slams down or closes faster than normal indicates the springs aren't providing adequate counterbalance.
If one spring is weaker than the other (or has broken), the door may hang crooked or move unevenly.
A breaking spring releases tremendous energy and produces a sound like a gunshot. If you hear this, stay away from the door and call a professional.
A properly balanced door should stay in place when stopped halfway. If it falls, the springs need attention.
We cannot stress this enough: garage door spring replacement is dangerous and should only be performed by trained professionals. Here's why:
Garage door springs are under tremendous tension, enough to seriously injure or kill. Torsion springs store enough energy to lift a several-hundred-pound door, and that energy must be safely released during replacement.
Professional spring replacement requires winding bars, clamps, and other specialized tools. Improvising with incorrect tools dramatically increases the risk of injury.
Springs must be precisely matched to your door's weight and properly tensioned. Incorrect springs or improper tensioning can damage your door or opener and create safety hazards.
A spring that releases unexpectedly can damage vehicles, walls, or other objects in the garage.
When you call Garage Door Titusville for spring replacement, here's what to expect:
1. Our technician inspects the entire door system to identify all issues 2. We measure and match the correct spring specifications 3. The door is safely secured and tension is released from old springs 4. Old springs are removed and new springs installed 5. Springs are precisely tensioned to the door's weight 6. The door is balanced and tested through multiple cycles 7. All safety features are verified
Spring life is measured in cycles (one cycle = one open and close). Standard springs last about 10,000 cycles, while high-cycle springs can last 25,000-50,000 cycles. For a typical household that opens the door 4 times daily, standard springs last about 7 years.
While springs will eventually wear out, you can maximize their lifespan by:
- Lubricating springs every few months, Keeping the door balanced, Scheduling annual professional maintenance, Not overloading the opener by manually stopping the door mid-cycle, Addressing minor issues before they stress the springs
Spring replacement costs vary based on spring type, door size, and whether one or both springs need replacement. Expect to pay $150-350 for most residential spring replacements. We recommend replacing both springs even if only one has broken, as they wear at similar rates.
A broken spring means your garage door is essentially unusable and may be a safety hazard.
