- The call
- Open the door by hand and it drifts back down on its own, a little at first and then all at once. Nothing is broken that you can see, but the springs along the tracks look tired, rusty and slightly sagging.
It is the first hard frost of the year and the door on the old detached garage has stopped halfway, squealing at one pulley. The springs are the ones that came with the door decades ago, orange with rust where they hang near the back wall.
In plain words
Choosing the right spring is a matter of weight, not colour. Extension springs are rated for the weight they are meant to lift, and the correct pair for your door is found by weighing the door itself with the opener released, then checking that figure against the wire size, coil diameter and length of the old springs. Paint colour on the end coil is only a hint; older springs fade, get overpainted or were never quite right to begin with. A pair matched to the measured weight gives a door that holds at half height and lifts with one hand, and an opener that works lightly.

How the visit goes
Scene 1
Securing the door with the springs slack
An extension spring is stretched tight when the door is closed and nearly relaxed when the door is fully open, so the first move is to get the door up. The technician pulls the opener's release, raises the door by hand if it will go, and clamps both vertical tracks below the bottom rollers so the door cannot come down. If a broken spring has left the door stuck partway, it is lifted and supported with the weight taken on clamps and props before anything else is handled. With the door held open, the springs, pulleys and hooks can be examined and removed like ordinary hardware, which is the whole reason the sequence begins this way.
Scene 2
Fitting a pair that matches the door
The new springs are selected from the door's measured weight and its height, which together give the rating and the stretched length required, and they are fitted as a pair even if one old spring looked sound. The technician checks each new spring's wire size, coil diameter and relaxed length against the specification before it goes up, and confirms the end loops suit the hanger and the pulley fork. The rear loop is hung on the hanger and the front loop takes the pulley fork. On heavier doors that carry two springs per side, all four are renewed together. Nothing is hooked to the door yet; the springs simply hang in place, slack, waiting for the cables.
Scene 3
Containment cables, and leaving them be
Your door now has a cable running through the middle of each spring, anchored at the back hanger and at the front of the track. It carries no meaningful load while the springs work, though a trace of slack as the door cycles is normal. Its job begins only if a spring ever breaks, when it holds the pieces on the cable instead of letting them fly. It should not be removed, used to hang anything, or tied back to the wall. If it ever looks badly slack, frayed or pulled from its anchor, call to have it corrected promptly rather than waiting for a routine visit. A home inspector looks for this cable when a house is sold.

What shapes the quoteHumber Valley Garage Door Co.
- How the door is sitting
- A door resting closed with one spring gone is straightforward. A door stuck partway, twisted in its tracks or with a cable wrapped around a pulley has to be supported and straightened first.
- Time of the call
- An evening, weekend or holiday visit costs the same amount as a weekday daytime appointment for an extension-spring replacement. The technician confirms the exact figure once the springs, cables and door weight have been checked on site.
- Converting to torsion instead
- Where the garage has the headroom, some owners take the opportunity to move to a torsion system. That is a different job with different hardware and is quoted as its own option.
FeesSame any hour
Have a question?
Will the lift cables be changed as well?
They are inspected every time and changed when they show fraying, rust at the bottom loop, or a kink from having jumped a pulley. Cables and springs are generally the same age, and with the door already open and the springs off, fitting new cables adds little to the visit. Bright, tight strands with clean loops can stay and are simply re-routed over the pulleys and set to the new springs.
Would a stronger spring make the door easier to lift?
Not in a useful way. The aim is a spring that matches the door's weight, so the door holds still wherever you leave it. A spring rated above that weight pulls the door up on its own, makes it hard to close, and leans on the opener to hold it down. A spring rated below lets it sink. Matched springs, set to the same hook position, give the light, even feel you want.
Why does the opener get adjusted after new springs?
Because the door is now much lighter for the opener to move. Over the years, as the old springs weakened, the opener's force setting may have been turned up to keep the door going, and its travel limits were set against a door that sat differently on the floor. Left alone, that extra force would push the newly balanced door too hard. Resetting force and travel, then repeating the reversal tests, matches the opener to the door it now has.
Springs & Hardware
- Garage Door Hinge ReplacementThe roller at the top of the second panel is leaning outward and only half of the wheel is still in the track.
- Garage Door Track Repair or ReplacementThe garage floor has settled at one corner, and the door now scrapes the concrete on that side while daylight shows at the other.
- Garage Door Cable ReplacementThere was a sharp crack from the garage, and when you went to look the door had dropped on one side and jammed.
- Torsion Spring ReplacementAfter pulling the red release cord, you tried lifting the door yourself and it would barely leave the floor.
- Garage Door Balance AdjustmentThe opener has started to groan on the way up.

2021 census: what it means at the door
Every square is one home in a hundred.
- 58 in 100 homes · older homes
- 23 in 100 homes · mostly attached
- About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.In a mature neighbourhood the garage door is often the single largest feature of the front elevation, so keeping the original look matters. Modern insulated doors come in raised-panel and carriage styles that echo the older designs while running on today's torsion hardware.
- Single-detached houses make up about 23% of homes in Toronto (2021 Census).Where housing is mostly attached, the common garage entrance may be a rolling grille or heavy sectional door with access by fob or remote, managed by the property. We service these operators, safety edges and photo-eyes, and coordinate with management so residents keep their access throughout.
