Your garage door is the heaviest moving object in most homes. What makes it glide up with the touch of a button is not the motor alone. It is the springs. They do the real lifting, counterbalancing the weight of the door so the opener only has to guide it. When a spring fails, the door becomes almost impossible to move, and the repair is one of the most dangerous jobs on a garage door. Here is why.
The two types of spring
There are two common spring systems, and knowing which you have helps you understand the risk.
Torsion springs sit on a metal shaft mounted horizontally above the door opening. As the door closes, the springs wind up and store energy. As it opens, they unwind and release that energy to help raise the door. Torsion systems are strong, controlled and long-lasting, which is why they are common on heavier and double doors.
Extension springs, sometimes called tension springs, run along the horizontal tracks on either side of the door. They stretch and contract as the door moves, extending when the door is closed and pulling back to help lift it open. They are typically found on lighter, single doors.
Both do the same job, counterbalancing the door’s weight. Both store a large amount of energy when the door is closed. That stored energy is exactly what makes them hazardous.
Why springs wear out
Springs are rated by cycles, with one cycle being a single open and close. Every cycle stresses the metal a little, and over years of daily use the spring eventually fatigues and breaks. Perth’s conditions can speed this up, as coastal salt air and general moisture encourage rust, and rust shortens a spring’s life. Lack of servicing also plays a part, since dry, unlubricated springs and worn components put extra strain on the system.
A broken spring usually announces itself. You might hear a loud bang like a gunshot from the garage, find the door will not open or feels enormously heavy, see a visible gap in a torsion spring, or notice the door closing too fast or crookedly.
Why this is not a DIY repair
It is tempting to save money and tackle a spring yourself, but this is the one garage door repair where that decision can cause serious injury.
A spring under tension holds enough stored energy to break bones or worse if it releases suddenly. Adjusting or replacing a torsion spring means controlling that energy with winding bars, and a slip can turn a bar or spring into a projectile. Springs almost always work as a matched pair, and replacing only one leaves the system unbalanced, which wears the new spring and strains the opener. Correct spring selection matters too, because the spring must be matched to the exact weight and size of your door. The wrong spring will not counterbalance properly and can make the door unsafe.
On top of the danger, the specialist tools and the experience to gauge the right tension are not things most households have. A professional, like from Perth Garage Doors replaces springs safely, in the correct pair, matched to your door, and then balances and tests the whole system so it runs smoothly.
What a professional repair involves
When a Perth Garage Door professional technician attends a spring failure, they safely release any stored tension, confirm the correct spring specification for your door, replace the springs as a set, then check the balance, cables, rollers and opener force settings so nothing else is left under strain. They will also spot related wear, such as frayed cables or worn bearings, before those cause the next breakdown. The result is a door that lifts smoothly, an opener that is not overworked, and a system that is safe to use.
Springs are the hardest-working and most dangerous part of your garage door. Whether you have torsion springs above the door or extension springs along the tracks, a failure needs prompt, professional attention. It is not worth risking a serious injury to save a callout fee, especially when a correctly matched, properly balanced repair also protects your opener and extends the life of the whole door.
