Torsion Spring Replacement in Heidelberg
Nothing broke outright, but the door has grown heavier each winter, opens more slowly and squeals as it moves.
In plain words
On a door with two springs, replacement usually starts with a conversation about scope. Both springs have completed the same number of cycles, so when one breaks the other is typically close behind, and replacing the pair together gives the door two matched springs sharing the load evenly. The technician explains what the installed system is, how each spring is loaded and what the door's weight calls for, then fits and winds the springs as a set. The result is a balanced door with a fresh cycle life on both sides rather than a repair that may be repeated soon.
How the visit goesLooking up at the coil above the door, you can see a clean split with a gap of several centimetres between the two halves. The rest of the spring looks fine, but the door has become almost impossible to move by hand.

How the visit goes


Confirming the system layout
Doors are set up in several ways, and the replacement has to match. The technician notes whether there is one spring or two, whether the shaft is a single piece or two halves joined by a coupler, and what the shaft diameter is. Drum type is read from the drums themselves: standard-lift drums for a normal ceiling, high-lift or vertical-lift drums where the door rises well above the opening, or a rear-mounted assembly in a low-headroom garage. Track radius and headroom are measured because they change how many turns the spring needs and which drums it must work with.
Finishing the job properly
After the balance and opener tests pass, the technician lubricates the new spring coils, bearings, hinges and roller bearings with a garage-door lubricant, leaving the track clean so the rollers run true. The old spring and any replaced parts are removed from the site. The customer is shown how the door should feel by hand, where the manual release is and how to use it, and what was installed, including the spring specification for future reference. A final look confirms clamps are off, tools are clear of the tracks and the area beneath the shaft is tidy.
A door that carries its own weight
The clearest change is in your hands: with the opener released, the door lifts with light, even effort and holds its position at mid-height instead of sliding down. That is what a balanced counterweight feels like. The door closes softly at the floor and rises without hesitation, and the opener runs with a calmer sound because it is guiding the door rather than hauling it. You can test this yourself any time by pulling the release cord with the door closed and lifting to waist height; a door that stays put is a door in balance.

What affects the quote
Cycle rating chosen
A standard-cycle spring and a high-cycle spring balance the door the same way but differ in wire and length. Choosing a longer-life spring is an option the household can weigh against how often the door is used.
Door size and weight
A double-width door, a solid wood door or a thick insulated door weighs far more than a single-width steel panel, calling for heavier wire, longer coils or more springs to balance it.
Oversize or non-standard doors
Very wide doors, tall doors, carriage-house doors with heavy overlays and light-commercial doors may need duplex springs, multiple springs or larger drums, which changes both the hardware and the method.
What to have ready
- Is the door currently closed, open, or stuck partway?
- What is the door made of: steel, insulated steel, wood or aluminum?
- How many springs are mounted above the door, one or two?
Torsion Spring Replacement: questions
QuestionsWhat happens if the header wood or centre bracket is damaged?
The centre bracket anchors the spring's reaction force to the framing above the door, so it has to be solid. If the header has split or softened, or the lag bolts have pulled, the technician can refasten into sound wood, add a reinforcing plate or replace the bracket before the new spring is wound. Dealing with this first keeps the shaft level and the spring pulling straight, which protects the bearings and the door.
Can a spring be adjusted rather than replaced?
A spring that is intact but has relaxed slightly can be given a little more tension, within limits, to restore balance; this is a normal adjustment on a door that has settled. A spring with a broken coil is replaced as a unit, since the wire has reached the end of its life. The technician checks the condition of the steel and recommends whichever restores a balanced, safe door.
What should I do before the technician arrives?
Keep the door closed and leave it alone, move any vehicle you can reach out of the way or at least clear the space in front of the door inside the garage, and make sure there is room for a ladder beneath the shaft. Note whether there is one spring or two and whether a cable is loose. A photo of the spring area, the drums and the opener helps the technician bring the right parts.
