What a torsion spring system actually does

It is a spring assembly on a steel shaft directly above the opening that uses torque, rotational force, to lift and lower the door. The spring unwinds, the shaft turns, the cable drums at each end wind the lift cables, and the cables pull the door up.

The spring is not lifting your door by stretching. It is lifting it by twisting. That distinction matters for sizing: a spring wound to the wrong tension for the door's actual weight will either overwork the opener or fail early.

The door comes down and the spring winds up, storing torque
You trigger the opener and the spring begins to unwind
The shaft turns, and the drums at each end turn with it
Both lift cables wind onto their drums together
The door rises in a balanced, controlled arc

For most residential doors that cycle runs somewhere between 1,500 and 2,000 times a year. If the configuration on your door has not been established yet, start at spring repair.

Torque, not stretchFront view

Single or double, decided by the door

A single spring carries the whole load. Two springs on the same shaft split it, so each one lasts longer, and if one fails the door still has partial support. Which one you get depends on measured weight and the space above the opening.

Single torsion

One spring centred on the shaft
Correct on lighter, single-car doors
The only option where header clearance is tight
Sized to measured weight, never to door size alone

A correctly sized single beats an unnecessary double every time.

Double torsion

Two springs on one shaft, either side of centre
Each wound the opposite way to its position
Load split, so each spring lasts longer
Needs enough header clearance above the opening

Common on heavier insulated and two-car doors, and only recommended when the weight and clearance justify it.

What I saw on a double-car door in West Allis

Single springs on heavy insulated doors are the most common mismatch I find.

The homeowner said the opener had been grinding for a few months and the door felt heavy on the manual release. It was a 16-foot insulated steel double-car door, and there was easily twelve inches of header clearance, the vertical space between the top of the frame and the ceiling. Plenty of room for a double setup.

The door had been on a single spring since the house was built, and that spring was undersized for the weight. Not by a massive margin, but enough that the opener motor had been compensating for years. The spring had not snapped, but the winding cones showed stress and the wire had a slight set to it, meaning it had permanently deformed from overloading. When one does go all the way, snapped spring repair handles it on the same visit.

We installed a double setup, two springs on the same shaft wound in opposite directions: left-wound on the left, right-wound on the right. Wind direction has to match position on the shaft or the system works against itself.

The door balanced at the halfway mark afterwards and the opener barely made a sound. The homeowner said it felt like a brand new system, which it essentially was.

Your door's weight drives the decision, not what was installed originally

We measure or estimate door weight on every diagnostic visit. Heavier insulated doors, two-car models especially, often benefit from a double configuration even where a single spring came with the house. After installation, balancing verifies the tension and confirms the load is spread evenly.

Header clearance decides whether a double setup is physically possible. Most homes here built after the 1980s have enough. Older low-ceiling garages sometimes do not, and in those cases we work with extension springs or a compact torsion alternative rather than forcing a configuration that will not fit. See extension spring systems.

No guesswork, and no springs ordered before the door has been checked.

Our standards on every torsion job

The same process on every Milwaukee visit.

Selected by door weight
Not by door size alone, and not from a chart.
Cycle rating matched to use
Heavier daily use gets a higher-rated spring.
Opposing wind directions
Left-wound and right-wound on the same shaft, each on its own side of centre.
Winding bars only
All tensioning done with proper bars. No substitute tools, ever.
Safety cables routed
Threaded through each spring as secondary containment before tensioning begins.
Cable drums inspected
Checked for wear and re-tensioned to match the new spring specification.
Greased properly
A full application on the coils, the shaft and the winding cones.

How the visit runs

Three phases: assess, install, prove the balance.

Phase one, about 30 minutes
Door measurement and system assessment
Width, height and an estimated weight from the material and insulation type. Header clearance checked to confirm single or double. The existing shaft, cable drums and winding cones inspected for wear, and the opener checked to see whether it has been compensating for a spring problem.
Phase two
Spring selection and installation
Springs selected, wound to the correct tension with proper winding bars and mounted to the shaft. On a double setup the left-wound spring goes left of the shaft centre and the right-wound goes right. Safety cables thread through both springs before tensioning begins, and the cable drums are re-tensioned to match.
Phase three, 15 to 20 minutes
Balance test and verification
The opener is disconnected and the door raised by hand to the halfway mark. A properly balanced door holds there without rising or falling. Then the opener is reconnected, five full cycles run, and we listen for grinding, uneven movement or cable slack. Sensor alignment is confirmed before we leave.

Milwaukee garages wear springs fast

Garages here cycle through extreme swings: an unheated garage can sit below zero in January and run past ninety in July. Steel contracts in cold, so a spring calibrated at room temperature is under extra stress on a January morning, exactly when the door is heaviest and the metal is stiffest.

Manufacturers rate springs for a cycle count at a controlled temperature, following DASMA practice, and cold-weather cycling works through that rating faster. We factor it into every selection, which means wire gauge and cycle rating chosen for the conditions rather than whatever matches the door size on a chart.

Torsion system questions, answered

What people ask before choosing single or double.

A double setup costs more, because it is two springs, both cable drums re-tensioned and a full balance test. The exact figure depends on the door's weight and the condition of the existing hardware. Both options are assessed on the diagnostic visit so you see the difference before any work starts, and on a heavy insulated door the extra usually comes back through longer spring life and less strain on the opener.

Most torsion jobs finish in two to three hours from arrival. Measuring the door, checking header clearance and inspecting the shaft takes roughly thirty minutes, installation and winding follow, and the balance test adds another fifteen to twenty. A double setup on a heavy two-car door can run slightly longer, and completion on the same visit is normal.

Only when the measured weight and available header clearance justify it. Single-spring setups work correctly on lighter single-car doors. We measure the door first and present both options with the reason behind the recommendation. Some low-ceiling garages here physically cannot take a double setup, and those get a correctly sized single spring instead.

Every torsion spring is wound left or right, and that orientation has to match its position on the shaft. A spring fitted the wrong way works against the system rather than with it, which causes immediate imbalance and can damage the cable drums within days. Wind direction is verified before any spring is tensioned: left-wound to the left of the shaft centre, right-wound to the right.

Cold makes steel contract, which adds stress on the mornings the door is already heaviest. Springs are rated for their cycle count at controlled temperatures, and a climate like this works through that rating faster. We choose wire gauge and cycle rating with cold-weather cycling in mind rather than door size alone.

A working opener can mask a worn or undersized spring for months; the motor compensates quietly until it cannot. The early signs are a door that feels heavy on the manual release or moves slightly slower than it used to. If it is a heavy insulated door that has run on a single spring for years, an assessment is worth booking before winter adds load to an already stressed system.
