Garage Door Spring Replacement
Broken torsion and extension springs swapped out using proper winding bars.

Balance and tension corrected on springs that are still sound but out of adjustment.
What's involved
Garage Door Spring Repair
The spring system should offset the door's weight so it can be moved smoothly without asking the opener to do the lifting. Spring repair examines problems within that counterbalance system, including incorrect tension, binding bearings, loose shaft hardware, or a spring that no longer suits the door. A snapped torsion spring is normally replaced, not patched; however, related components may be repairable when they are preventing a sound spring from working properly. The door's balance, lift hardware, and travel are checked before deciding on the correct work. Book the assessment with the online form.

Symptoms
Signs You Need This Service
- The door is noticeably heavy when lifted by hand.
- A loud snap was heard and the opener now struggles to raise the door.
- The door falls or rises when left around waist height.
- The shaft and cables appear to move unevenly during travel.
- There is a visible separation between coils in a torsion spring.
Repair or replace?
Springs are rated in cycles rather than by a guaranteed calendar date. A common residential rating is approximately 10,000 open-and-close cycles, often around 7 to 12 years where the door is used normally. Usage, corrosion, door weight, and roller condition change that outcome. Correct sizing and freely turning bearings help a spring wear evenly; a broken coil normally calls for replacement rather than repair.

Root causes
What Actually Goes Wrong
Cycle wear
Spring steel bends and relaxes every time the door opens or closes. After enough cycles, fatigue can create a fracture or leave the system short of lifting force. The loss is often sudden to the homeowner, although the spring has been accumulating wear over time.
Mismatched spring
Spring dimensions and winding direction must suit the door's actual weight, height, drums, and lift arrangement. A weak spring leaves too much work for the opener, while an overly strong spring can make closing unpredictable and prevent the door from staying where it is placed.
Bearing resistance
The torsion shaft turns through centre and end bearings as the door moves. A bearing that is dry, worn, or seized interferes with that rotation. Instead of delivering spring force evenly, the system becomes noisy, uneven, and harder on the spring coils and cables.
Shifting shaft hardware
Drums, winding cones, and set screws must remain fixed in their intended positions. When hardware moves, cable travel and stored spring force can change at the same time. The result may resemble an opener problem, but the underlying issue is often incorrect counterbalance behaviour.
Local conditions
Why This Matters in Markham
At Buttonville Airport in Markham, January's mean daily minimum is −10.1 °C, and the station has recorded a low of −35.2 °C. In that cold, lubricant thickens and rollers or seals can add resistance to an already tired lift system. Cold weather does not usually break a healthy spring on its own, but it can reveal a spring that is near the end of its cycle life or hardware that is no longer moving freely. A door that suddenly feels heavy during a cold spell deserves a balance check instead of a higher opener-force setting.
Safety
What to Handle Yourself
Spring work is not a do-it-yourself adjustment. Torsion springs, winding cones, cables, and drums operate under stored force, and a slipped tool or released set screw can cause serious injury. Do not touch a spring with a visible gap, loosen fittings on the shaft, or make the opener haul a door that feels heavy. Leave the door closed if possible, avoid the hardware, and use the online form to arrange an assessment confirmed by email.
The visit
How We Work Through It
-
Check manual balance
With the opener disengaged when conditions allow, the door is assessed by hand at several positions. Its weight and tendency to drift reveal whether spring assistance is low, excessive, uneven, or being masked by friction somewhere else in the operating system.
-
Review lift components
The springs, shaft, drums, cones, bearing plates, and brackets are examined as one assembly. This makes it possible to distinguish a fatigued spring from a binding bearing, loose fastener, or earlier installation mismatch that altered normal balance. This also checks whether the existing parts have been installed in a way that preserves proper cable alignment.
-
Address serviceable faults
Repairable bearing, hardware, or adjustment issues are corrected where appropriate. A fractured or substantially fatigued spring is identified for replacement instead of being treated as a candidate for a short-lived repair. The door's actual load guides the work rather than appearance alone.
-
Confirm the result
The door is moved through several manual positions to verify that it stays reasonably balanced and does not bind. Only then is the opener returned to use and checked, so its travel settings are not compensating for a problem in the lift system.
Questions
Garage Door Spring Repair FAQs
Can a broken torsion spring be fixed instead of replaced?
A torsion spring that has fractured is normally replaced because the broken steel cannot regain dependable strength. The rest of the system still needs inspection, since a seized bearing, incorrect spring selection, changed door weight, or poor travel path may have shortened the spring's service life. Correcting those contributing conditions protects the replacement. That approach reduces avoidable strain on connected hardware.
Why does the opener hum without lifting the door?
The motor may be attempting to move a door that has lost its counterbalance assistance. An opener is intended to guide a properly balanced door, not lift the full door weight. Stop using the unit until the lift system is checked. Continuing to operate against that load can damage gears, the rail, or the door arm. It also provides a safer basis for the next decision.
If one spring has failed, should the other be checked?
Yes. Springs installed as a pair generally experience similar cycles, so the spring that remains intact may also be worn. Its size, condition, and ability to work with a matching companion are considered during service. The aim is even lifting force across the door, not simply restoring movement on one side. This keeps the door system more predictable during normal use.
Will lubricating the spring solve a new noise?
Light lubrication may quiet normal spring movement, but it does not renew weakened steel or correct a damaged coil, seized bearing, or poor tension setting. If the noise arrives with a heavier door, uneven lift, or visible separation in the coils, stop treating it as a minor sound issue. The complete counterbalance system needs assessment before the door is used routinely.
