Torsion Springs Are Sized to the Door, Not Sold Off a Shelf
A torsion spring is rated by wire diameter, coil length, and inside diameter, and all three have to match the door's exact weight and the drum it winds onto. Get the size wrong and the door either slams down too fast or won't stay open on its own, which strains the opener either way. Lighter single doors, common on older homes around Kirkwood and Webster Groves, often run on a single torsion spring, while wider 16-foot double doors typical of newer construction in Chesterfield and Wildwood almost always need a two-spring system to balance the extra weight evenly across the shaft.
Most residential torsion springs are rated for around 10,000 cycles before metal fatigue sets in, and St. Louis's swing between humid summers and cold winters tends to shorten that window. If the spring turns out to be only one part of a bigger problem, like a bent track or worn rollers, that broader work falls under garage door repair rather than a spring swap alone. And if you're dealing with a fully stuck door outside normal hours, that's the same failure covered under emergency garage door repair, just handled after hours instead of during the day.
Torsion Spring Service
Single Torsion Spring Replacement
Common on lighter, single-car doors. We match the wire gauge and wind count to the door's weight rather than installing a generic universal spring.
Double Torsion Spring Systems
Standard on most 16-foot double doors, where two springs share the load evenly across the shaft. Both get replaced as a matched pair for balanced tension.
Correct Wire Gauge and Wind Count
The spring's wire thickness, coil length, and number of turns are calculated from the door's weight and drum size, not estimated by eye.
Torsion Cable Replacement
Torsion cables share the load with the spring system and wear alongside it. We check and replace them together so a fresh spring isn't paired with a worn cable.
Safe Winding and Setup
Torsion springs hold significant stored tension once wound. We use proper winding bars and technique so the door opens smoothly and the spring is set to the correct number of turns.
Matched Springs, Set Right
"I didn't realize our double door needed two matched springs instead of just replacing the broken one. Glad they explained it before winding anything."
"Quiet, smooth operation again after years of a loud, uneven close. The difference was immediate."
Torsion Spring Questions, Answered
Can I replace a garage door torsion spring myself? +
It's not recommended for a first attempt: a wound torsion spring stores enough tension to cause serious injury if a winding bar slips or the wind count is off. Professional replacement with the correct tools takes a fraction of the time and avoids that risk entirely.
How do I know which spring to buy for my garage door? +
Spring sizing depends on the door's exact weight, the track drum diameter, and the shaft length, which is why guessing from a hardware store chart often leads to the wrong spring. We measure the actual door and hardware before recommending a size.
How do I tell what torsion spring I need for my garage door? +
The three numbers that matter are wire diameter, coil length, and inside diameter, all of which are calculated from the door's weight rather than read off the old spring, since the old one may already have been undersized. That's the check we run before winding a replacement.
Can you replace just one spring on a garage door? +
On a single-spring door, yes, since there's only one to begin with. On a double torsion system we replace both together, because the unbroken spring is usually close to the same cycle count and near failure itself.
What is the average lifespan of a garage door torsion spring? +
Most residential torsion springs are rated for roughly 10,000 cycles, which works out to about seven to ten years on a door used several times a day. Heavier daily use, or a garage used as the main entrance, shortens that window.
