Extension Spring Replacement

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.

In plain words

A spring visit follows a fixed order, so you know what to expect. The technician releases the opener, raises the door fully and clamps it, because an extension spring is at its slackest with the door open. Then both springs, the pulleys, cables, hangers and containment cables are inspected and the door is weighed. Old springs come off, new ones go on with containment cables threaded through, cables are routed over the pulleys and both sides are hooked at the same setting. The clamps come off, the door is balanced by hand, and only then is the opener reconnected, adjusted and put through its reversal tests.

How the visit goes

Illustrative garage doors scene
  1. Scene 1

    The rest of the door, and why the spring went

    A spring rarely fails on its own, so the first look ends with the door it was lifting. The technician checks the rollers for cracked wheels and bent stems, the hinges for splits, the track for a bend or a bracket pulled off the jamb, and the bottom section for a dent that catches. The opener's force setting is noted, since an opener turned up to compensate for tired springs will overpower the new ones. And the history matters: a door recently fitted with insulation panels or windows weighs more than the springs were chosen for, and a door that has been closed onto snow or a bin has had its cables jolted.

  2. Scene 2

    Balancing the door by hand

    Balance is judged with the opener still disconnected. The technician lowers the door to the floor, then lifts it: it should rise with modest effort, stay put when let go at about waist height, sit steady when fully open, and come down under control rather than dropping. If it sinks, both springs need a little more stretch and each S-hook is moved one hole to take up cable; if it climbs on its own, one hole the other way. Adjustments are always made in pairs, with the door open and clamped again each time, so the two springs stay equal. Two or three rounds usually settle it.

  3. Scene 3

    A monthly look along the springs

    Extension springs are easy to inspect because they hang in plain view. Once a month, with the door fully closed so the springs are stretched, stand inside and look along each one from the back hanger to the pulley. The coils should be evenly spaced along the whole length; a section stretched wider than the rest is a spring losing its temper. Then raise the door and look again: with the door open the coils should close up tight, and both springs should hang at the same height. Rust bloom, a pulley that sits crooked, a cable off its groove or a containment cable hanging loose are all worth a call while they are still small.

In the van

  • Pulleys (sheaves) and forks
  • S-hooks and adjusting clips
  • Extension springs, matched pair
  • Containment (safety) cables
  • Rear spring hangers and angle iron

What shapes the quoteThorold Garage Door Repair Co.

Containment cables to add
A door that never had containment cables gets them with the new springs, along with anchor hardware into the framing. It is a small parts line and a worthwhile one.
Working room around the springs
Shelving, a stored canoe or a car parked under the tracks slows the work along the horizontal run. Clearing the sides of the garage beforehand keeps the time on the quote short.
Corroded fasteners
In an unheated garage the bolts through pulley forks and hanger brackets rust solid; freeing or cutting them and fitting new hardware takes time and shows in the parts list.

Frequently asked questions

The door creeps open on its own. Is that a spring problem?

Usually, yes. A door that rises from the floor or from halfway without help has springs pulling harder than the door weighs, which happens when a heavier-rated pair was fitted, when the hooks were set with too much stretch, or when a door has been made lighter by a panel change. It also puts strain on the opener, which has to hold the door down. Weighing the door and fitting the correct rating, set evenly, settles it.

What is the difference between extension springs and torsion springs?

They balance the door in different places. Extension springs are the two long coils that run beside the horizontal tracks and stretch as the door closes; they work through pulleys and cables. A torsion spring is wound on a shaft above the door opening and turns drums that wind the cables. The parts, the way tension is set and the service itself are different, so it helps to say which you have when you call.

Do the pulleys need replacing at the same time?

Often, yes. Each side has two pulleys, one on the spring and one fixed at the front of the track, and the cable rides over both on every trip. A pulley whose wheel has worn a sharp groove, or whose bearing has stiffened, drags on the cable and adds load the spring has to overcome, which is a common reason the old spring wore early. Pulleys that spin freely and run true can stay.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 55 in 100 homes · older homes
  • About 55% of homes in Thorold were built in 1980 or earlier, according to the 2021 Census.Where houses are older, the garage often sits beside the house rather than beneath a bedroom, so noise is a smaller concern and durability a larger one. Heavy-duty rollers, a properly sized torsion spring and cold-rated lubricant make an old door dependable for years.
  • Single-detached houses make up about 69% of homes in Thorold (2021 Census).Households in detached homes often have several remotes, a keypad and a phone app between family members and their cars. We keep all of them programmed to the opener, replace the ones that have failed, and explain how to add a new one when a car changes hands.
