Extension Spring Replacement

The home inspector's report on the house you are buying flags the garage door: extension springs with no safety cable running through them, coils showing rust, and a door that sank when he lifted it partway. The seller has never had it looked at.

  1. When a spring breaks, the safe approach for the household is to leave the door where it is, keep people and vehicles clear, and avoid running the opener, which can damage the top section, the trolley or the gear drive.

  2. Pull the manual release only when the door is fully closed unless a technician asks otherwise; a door disconnected while partly open can move on its own if the springs are out of balance.

  3. Never drive a vehicle at a closed door to get out; the door collapses and the stored tension in the counterbalance is released. Use the release, the outside key release, or a technician.

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.

Sound familiar?

The opener groans on the way up and the door slams the last foot on the way down, hard enough to rattle the windows. The motor is the same one it always was; something in the springs has stopped doing its share.

How the visit goes

  1. 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.

  2. 2

    Threading the containment cables

    Before a spring is hung, a containment cable is fed through the centre of its coil. One end is anchored at the rear, to the hanger or the framing behind it, and the other is run forward past the pulley and fixed to the bracket at the front of the track or to the wall, with enough slack that the cable never carries load while the spring works. The cable is checked to be clear of the pulley wheel and the lift cable so nothing rubs. Both sides are done the same way, whether or not the old installation had them. A spring that breaks in future is held on the cable rather than crossing the garage.

  3. 3

    The numbers that stay with the door

    Before leaving, the technician tells you what the door weighed, which spring rating and length went on, whether the pulleys and cables were renewed, and which hook position the cables were set to. Write it on a card by the opener or inside the door's manual. Extension springs are sold by rating and length, so the next set can be ordered from that card without weighing the door again, and a technician arriving later can see at a glance whether the door has been altered since. Add the date and roughly how many times a day the door is used; together those two facts give a fair idea of when the springs will be due again.

What affects the quote

  1. 1

    One spring per side or two

    Heavier doors sometimes carry a pair of springs on each side rather than one. Four springs, four containment cables and the extra setting time show as their own lines.

  2. 2

    Condition of the lift cables

    Cables with fraying, rust at the loop or a kink are renewed as a pair while the springs are off. Sound cables are re-routed and set, and the quote says which applies.

  3. 3

    Weight added since the door went in

    Insulation panels, windows or a wood overlay fitted after the original springs mean a heavier rating than the old pair. The door is weighed and the quote reflects the door as it is now.

Extension Spring Replacement: questions

Advice · (289) 805-6879

What can I do to make the new springs last?

Three things. Spray the springs, pulley axles and hinges with a garage-door lubricant twice a year, which slows rust in an unheated garage. Keep the threshold clear of bins and packed snow so the door never stops short with the springs still pulling. And leave the opener's force setting where the technician put it, since a door that starts needing more push is a balance question rather than a dial to turn.

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.

What if the spring hanger has pulled loose from the ceiling?

It is put right as part of the job. The rear hanger takes the full pull of the spring on every cycle, and lag screws driven into thin plywood, a split joist or drywall work loose over the years, which is often why a door slowly goes out of balance. The technician re-fixes the hanger with fresh lag screws into solid framing, or adds a length of angle iron to reach it, before the new springs are hung.

What the census means at the door

58%

Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.

Extension springs are common on older doors, and they should carry a safety cable through the middle so a broken spring is held rather than flung. Adding those cables is a small job the technician checks for and offers on any older door he services.

23%

Single-detached houses make up about 23% of homes in Toronto (2021 Census).

Townhouse rows generally have a narrow single door on each unit, with shared walls on both sides. Noise from a chain opener or dry rollers carries straight into the neighbour's home, so quiet belt-drive openers and nylon rollers are a popular and considerate choice here.
