Counterbalance brought back into adjustment on springs that are still sound.

Springs specified from door weight and drum size, then wound to the calculated turns.
What's involved
Garage Door Spring Replacement
When a torsion spring breaks, the door stops being a door. The counterbalance that made a heavy insulated section set liftable is gone, the whole weight lands on the opener and the cables, and the correct response is replacement rather than repair. Spring replacement is a specification job as much as a fitting job: the new spring has to match the door’s actual weight, its height and the drum size, which is exactly the calculation most often skipped when a door has been swapped by somebody else in the past. Milton’s oldest post-2000 subdivisions are now reaching this point in numbers.

Symptoms
Signs You Need This Service
- A visible gap of a few centimetres in a spring coil above the door
- A bang from the garage followed by a door that will not lift
- The opener runs, the door barely moves, and the motor labours
- The door is far too heavy to lift by hand with the opener disconnected
- The door lifted a foot, stopped, and dropped straight back down
Repair or replace?
Spring life is measured in cycles, and the number of cycles a door sees per year depends entirely on the household rather than on the door. A family that uses the attached garage as the main entrance will get through a given rating far faster than a household that opens the door at weekends, which is why higher-cycle springs are frequently the better value on Milton’s four-bedroom subdivision homes. Cables, rollers and bearings age alongside the springs and get inspected at the same visit.

Root causes
What Actually Goes Wrong
Rated cycles used up
Springs are rated in cycles, not years. Every open and close is one cycle, so a household passing through the garage several times a day reaches the rating in a fraction of the time a lightly used door takes.
Springs undersized from the start
A spring set that never matched the door it was carrying runs over-stressed on every cycle and fails early. This is the usual explanation when a door replaced by a previous owner has needed springs sooner than expected.
Corrosion at the coils
Steel that spends winters in a damp garage with road salt carried in on vehicles pits at the surface, and a pit is where a fatigue crack starts. Unlubricated coils rub against each other and accelerate the same process.
Cold snapping already-fatigued steel
Cold does not by itself break a sound spring, but it is unforgiving of one that is nearly finished. With a January daily mean of -6.8 C, Milton’s spring failures concentrate in the coldest weeks of the year.
Local conditions
Why This Matters in Milton
Beaty and Clarke were the first of the new Milton subdivisions, with 61 per cent of Beaty dwellings built between 2001 and 2005 and 41 per cent of Clarke’s in the same window, so those are the streets where original builder springs are reaching their rated cycles now. Dorset Park is the other pattern: 85 per cent of its dwellings date from 1961 to 1980 and two thirds of its properties have an attached single garage, so replacement springs there are sized for narrower 1970s doors rather than for modern builder doubles.
Safety
What to Handle Yourself
This is the one job on a garage door that a homeowner should not attempt. A torsion spring at working tension holds enough energy to break an arm or worse, winding bars are specific tools with no safe substitute, and a broken spring leaves the door held only by cables that may already be compromised. Keep vehicles and children out of the opening, leave the opener disconnected so nobody can energise it, and do not try to lift the door.
The visit
How We Work Through It
-
Weigh and measure the door
The replacement spring is calculated from the door’s weight, its height and the drum diameter, not guessed from what was on the shaft. Wire size, inside diameter, length and wind direction all follow from that.
-
Release the old tension safely
The remaining tension is wound out with proper bars, the shaft is supported, the drums are marked, and the old spring comes off in a controlled sequence rather than being cut free.
-
Fit as a matched pair where the door has two
On a two-spring door both are replaced together. The survivor has carried the same load for the same number of cycles, and pairing new steel with old guarantees a second callout.
-
Wind to specification and prove the door
Tension is wound to the calculated turns, cables are seated and the drums set, then the door is balanced by hand, cycled under power, and its safety reverse and photo eyes checked.
Questions
Garage Door Spring Replacement FAQs
One spring broke. Do I have to replace both?
It is the right call on a two-spring door and we recommend it as standard. The two springs were fitted at the same time, share the load equally, and have carried the same number of cycles, so the intact one is at a similar point in its fatigue life. Fitting one new spring beside an old one also unbalances the pair, which makes the door track unevenly and puts asymmetric load through the drums. Replacing both is one visit, one setup and one correct calculation.
How do I know it is the spring and not the opener?
Disconnect the opener with the door closed and try to lift by hand. If the door is far too heavy to raise, the counterbalance has failed and the opener was only masking it. Look along the spring on the shaft above the door as well: a broken torsion spring shows an obvious gap of a few centimetres where the coil has separated. If the door lifts easily by hand but will not move under power, the fault is in the operator instead.
Can I get a stronger spring so it never breaks again?
You can get a higher-cycle spring, which is a genuinely useful upgrade, but not one that never wears out. Higher-cycle springs use different wire and diameter combinations to reach the same lifting force with more fatigue life, and on a heavily used family door they usually justify themselves. What you should not do is fit a spring that lifts harder than the door needs: an over-tensioned door fights its own weight, wears the top fixtures and will not stay down properly.
How long does the visit take?
A straightforward torsion spring replacement on a standard residential door is normally completed in a single visit, including the balance check and the safety tests afterwards. What extends it is discovering something else: cables that have work-hardened or frayed, a centre bearing that has failed, drums that have scored, or an anchor bracket whose backing needs attention. We tell you what we have found before doing extra work rather than after.
