Torsion or Extension: Which Springs Does Your Door Use?

Look above the closed door. A steel shaft with one or two large coils means torsion. Long, stretched springs running beside the horizontal tracks mean extension. We replace both types.

Torsion Springs

Most GTA homes

Mounted on a shaft above the door opening, torsion springs lift the door by twisting rather than stretching. They deliver smoother, more controlled travel, keep the door balanced across its full width, and are the standard on homes built or renovated in the last two decades.

  • How it liftsRotational torque on a steel shaft
  • Typical lifespan10,000–25,000 cycles by rating
  • Failure behaviourLoud bang; door stays down safely
  • Our replacement stockOil-tempered, multiple wire sizes

Extension Springs

Older & low-headroom garages

Extension springs stretch along each horizontal track and pull the door up from both sides. They are common in older Toronto and Scarborough homes and in garages without the headroom for a torsion shaft. Each spring works independently, so uneven wear can pull the door crooked.

  • Typical lifespan8,000–10,000 cycles
  • Failure behaviourCan whip — safety cables essential

Why Springs Matter

What a Spring Actually Does for Your Door

A double garage door weighs as much as a refrigerator — often 90 to 180 kilograms. Your opener is not what lifts that weight. The springs are.

  1. The spring stores the door's weight as tension

    When the door closes, cables wind the spring tighter. That stored energy offsets almost the entire weight of the door, which is why a healthy door can be lifted with one hand.

  2. The opener only guides the motion

    A residential opener produces modest force by design. It relies on the counterbalance doing the heavy work — which is why a broken spring makes even a strong opener give up or strip its gears.

  3. Every open and close is one cycle of fatigue

    Steel flexes and recovers with each cycle until microscopic cracks grow into a break. Cycle count, not age alone, is what determines when a spring fails.

  4. Correct sizing is everything

    Springs are matched to door weight by wire diameter, coil diameter, and length. A close-but-wrong spring leaves the door too heavy or too light, wearing out the opener and hardware early. We weigh and measure rather than guess.

Choose Your Lifespan

Standard or High-Cycle: A Choice Worth Understanding

One cycle is one full open and close. A family using the garage as the front door easily puts 6–10 cycles a day on their springs. Here is how the ratings translate to real years.

10,000 cycles — standard
≈ 5–8 years at 4 cycles/day

The builder-grade rating installed on most new homes. A sound, economical choice for garages used a few times a day. This is the spring your door most likely has now.

Most chosen upgrade
15,000–20,000 cycles — high-cycle
≈ 10–14 years at 4 cycles/day

A longer coil spreads the same work across more steel, cutting stress per cycle. For a modest price difference, the replacement interval roughly doubles — the better value for most busy households.

25,000 cycles — extended
≈ 17+ years at 4 cycles/day

For heavy daily use — home businesses, large families, or garages that serve as the main entrance. Often the last set of springs the door will ever need.

Catch It Early

Six Signs a Spring Is Failing or Already Broken

Springs rarely fail without notice. These are the signals we hear about most from GTA homeowners — and what each one means.

01

A loud bang from the garage

The sound of stored tension releasing in an instant. Homeowners often mistake it for something falling over. If the door will not lift afterwards, the spring has snapped.

02

A visible gap in the coil

Look at the shaft above the closed door. A healthy torsion spring is one continuous coil; a broken one shows a clean two-inch separation where the steel let go.

03

The door opens a few inches, then stops

Modern openers sense excess weight and reverse for safety. The motor is protecting itself from lifting a load the spring should be carrying.

04

The door feels extremely heavy by hand

Pull the red release cord and lift carefully. A balanced door lifts with light effort; if it takes real strength, the counterbalance has failed or lost tension.

05

Squealing or popping during travel

Dry, corroded coils grind against themselves before they fail. Lubrication helps, but persistent noise from the spring area deserves an inspection. See our popping noise guide.

06

The door drifts down from halfway

A door that will not hold position at mid-height has lost spring tension. It may still work, but every cycle is straining the opener. Our balance service corrects this before a full failure.

Why We Recommend Replacing Springs in Pairs

When a two-spring door breaks one spring, the other has endured exactly the same number of cycles and is usually weeks or months from its own failure. Replacing only the broken side leaves the door lifting unevenly on mismatched tension — and sets you up for a second service call and a second labour charge.

Replacing the pair costs only the price of the second spring while the technician is already on the ladder, restores even balance across the door, and resets the whole counterbalance to a known lifespan. It is the honest recommendation, and we will explain it on your written estimate rather than surprise you.

On-Site Protocol

How We Replace Your Springs

A disciplined procedure keeps the job safe and the result precise.

Measure

Weigh & spec the door

We measure door weight, height, track radius, and drum size, then read the old spring's wire diameter, inside diameter, and length to confirm the correct replacement — not just a close match.

Secure

Lock down the system

The door is clamped to the track, the opener is disconnected, and remaining tension is released in controlled quarter-turns with proper winding bars.

Install

Fit & wind new springs

New oil-tempered springs go on the shaft with fresh centre bearing inspection. Winding turns are calculated from door height and drum size, then set precisely.

Verify

Balance & safety test

The door must float at mid-height without drifting. We reset opener force limits, test the safety reversal, lubricate the coils, and document the work on your warranty invoice.

Built for Ontario Winters

Why GTA Springs Break in January

Spring failures spike during cold snaps, and it is not a coincidence. Steel becomes more brittle as temperatures fall below −15°C, so a coil already fatigued from years of cycling is far more likely to let go on a frigid morning — usually on the first open of the day.

Cold also thickens ordinary grease into a paste that binds the coils instead of protecting them. That is why our technicians use synthetic, non-gumming lubricant rated for Canadian winters, and why we install oil-tempered springs: the heat treatment leaves the steel less brittle in deep cold than untempered wire.

If your springs are past the five-year mark, a pre-winter maintenance visit can measure remaining balance and catch a tired spring before the season does. Our winter preparation guide covers what you can check yourself.

Common Questions

Spring Replacement FAQ

Straight answers about cost, safety, and what to expect.

The four tell-tale signs: a loud bang from the garage, a door that will not lift or rises only a few inches, a visible two-inch gap in the coil above the door, and a door that feels extremely heavy when lifted by hand. If the door is simply unresponsive with no bang and no gap, the issue may be the opener instead — our broken spring guide walks through telling them apart.
Replacing a pair of torsion springs on a typical double door in the GTA generally runs $250 to $450 installed. Single-car doors and standard extension springs sit toward the lower end; oversized, insulated, or wood doors need heavier springs and sit higher. High-cycle upgrades add a modest amount. Every job is confirmed with a written estimate before work begins.
We recommend it, and we will show you why on site: both springs have identical mileage, so the survivor is typically close to failure itself. Replacing the pair while the technician is already set up costs only the second spring, keeps tension even across the door, and avoids a repeat service call. That said, it is your door and your decision — the estimate shows both options.
We do not recommend forcing the door. Without its counterbalance, the full weight of the door is unsupported — lifting it manually takes two strong adults, and it can slam down if grip is lost. Running the opener risks stripping its drive gear and bending the top panel. If the car is trapped, mention it when you call and we will prioritize the scheduling options available.
A wound torsion spring stores energy equal to the full weight of your door. Releasing or setting that tension requires proper winding bars, correct technique, and knowing the right number of turns for your door's height and drum size. Improvised tools — screwdrivers, rebar — are the cause of serious hand, arm, and head injuries every year. This is one repair where the professional fee is genuinely the safer spend.
A standard torsion pair takes about 45 minutes to 1.5 hours, including balance testing, opener force adjustment, and lubrication. Our trucks stock the common wire sizes used across GTA homes, so nearly all replacements finish in one visit.
