Re-tensioning and rebalancing for intact springs that have gone out of adjustment.
What's involved
Garage Door Spring Repair
The lifting system should make a garage door feel controlled rather than dead-heavy. Spring repair addresses faults in the counterbalance assembly, including incorrect tension, damaged bearing plates, worn bearings, and springs that no longer match the door's weight. On many doors, a fully broken torsion spring is replaced rather than patched; repair work can also correct a related component that is making a spring work poorly. We assess the door's balance, hardware condition, and cycle history before deciding what can be repaired safely.

Symptoms
Signs You Need This Service
- The door feels much heavier than usual when lifted manually.
- A sharp bang came from the garage and the opener now strains.
- The door drifts down after you raise it halfway.
- The shaft turns unevenly and the door lifts at different speeds.
- A coil has a visible gap or hangs out of alignment.
Repair or replace?
Torsion springs are commonly rated by cycle count rather than calendar age. Standard residential springs are generally rated around 10,000 open-close cycles, often about 7-12 years for typical use, while higher-cycle options can last longer. Springs that are correctly sized and paired with freely moving rollers and bearings tend to wear predictably. A broken coil is normally replaced; adjacent hardware may be repairable.

Root causes
What Actually Goes Wrong
Cycle fatigue
Every opening and closing flexes the spring steel. Over thousands of cycles, the metal can fatigue until a coil breaks. The system no longer provides enough torque to counter the door's weight.
Incorrect spring sizing
A spring must match the door's weight, height, and drum arrangement. A spring that is too weak leaves the opener doing lifting work; one that is too strong can pull the door upward or make closing control poor.
Worn shaft bearings
Torsion springs turn on a shaft supported by end and center bearing plates. When a bearing binds, spring torque is not transferred smoothly, causing noise, uneven winding, and added wear on the spring coils.
Loose winding hardware
Set screws, winding cones, and cable drums must remain secure on the shaft. Movement in this hardware changes spring tension and cable tracking. It can make a door appear to have an opener problem when balance is the real issue.
Local conditions
Why This Matters in Mississauga
Southern Ontario's repeated freeze-thaw periods place a changing demand on a spring system. A door may move freely during a mild afternoon, then meet a colder seal, stiffer rollers, and thicker lubricant the next morning. That added resistance does not usually break a healthy spring by itself, but it can expose a spring already near the end of its usable cycle life. Checking balance as winter begins is more useful than waiting for a heavy door to reveal the problem.
Safety
What to Handle Yourself
Garage door springs are not a homeowner adjustment. A torsion spring is wound under substantial force, and associated hardware is loaded. A slipped tool or released cone can cause serious injury. Do not touch a spring that has a gap, loosen hardware on the shaft, or run the opener to overcome a heavy door. Leave door closed and book the spring assessment online.

How We Work Through It
-
Measure door weight
We disconnect the opener and assess the door's manual weight and balance. That establishes whether spring force is low, high, uneven, or being interrupted by friction elsewhere.
-
Inspect spring assembly
The shaft, coils, cones, drums, bearing plates, and mounting brackets are examined for fractures, wear, movement, or a mismatch between the existing spring and the door.
-
Correct repairable faults
Where the spring remains serviceable, we correct associated bearing, hardware, or tension issues. A fractured or severely fatigued spring is identified for replacement rather than an unreliable temporary fix.
-
Verify balance
The door is moved by hand through several positions and should stay near the position where it is left. The opener is then reconnected and its travel is checked without making it compensate for poor balance.
Questions
Garage Door Spring Repair FAQs
Can a broken torsion spring be repaired?
A broken torsion spring is normally replaced because the fractured steel cannot be restored to dependable strength. The repair assessment can still find and correct the reason it wore poorly, such as a binding bearing, wrong spring size, or a door-weight change that affects balance.
Why does my opener hum but not lift the door?
The opener may be trying to lift a door that has lost its spring assistance. An opener is designed to guide a balanced door, not hoist its full weight. Stop using it until the balance is checked, because continued operation can damage the opener gear.
Should both springs be inspected if only one failed?
Yes. Paired springs have usually performed a similar number of cycles, so the unbroken spring may also be well advanced in age. Inspection considers its condition and remaining serviceability. The practical choice depends on the door's balance requirements and whether matching spring force can be maintained safely.
Can I lubricate the spring to fix the noise?
Appropriate garage-door lubricant can reduce ordinary coil noise, but it cannot repair fatigue, a crack, or incorrect tension. Noise combined with a heavy door, jerky travel, or a visible gap deserves inspection. Do not assume lubrication makes a damaged spring safe. Book an assessment instead.
