Extension Spring Replacement in Georgian Heights

You pulled the red cord to open the door during a power cut and it barely moved. Lifting it took your whole weight, and when you let go it came down hard.

Extension Spring Replacement

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

Georgian Heights

How the visit goes

  1. Pulleys, cables and the hooks that set them

    Each side of an extension system has two pulleys, one on the moving end of the spring and one fixed at the front of the horizontal track, and a lift cable that runs from the bottom bracket over both to an S-hook or clip on the track hanger. Each pulley is spun to feel for a rough bearing and looked at for a wheel worn to a sharp groove or wobbling on its bolt. The cables are followed for fraying, rust at the bottom loop and a wrap that has slipped off a pulley. Worn pulleys and cables are renewed with the springs, since a seized pulley is often what shortened the old spring's life.

  2. Setting both sides to the same hole

    The initial tension is set with the door open and clamped, so the technician is adjusting slack springs rather than loaded ones. Each cable's S-hook is placed in a hole on the hanger, or its clip set to a mark, and the two sides are put at the same position. The cables are drawn to the same snugness so that neither corner of the door is being pulled ahead of the other. A level across the top section confirms the door is square in its tracks. Only when both sides read the same do the clamps come off and the door come down for its first balance check.

  3. A clear threshold and an honest opener

    Two habits protect the new springs from the shocks that shorten a spring's life. The first is the floor: a door that comes down on a bin, a bike wheel or a ridge of packed snow stops short while the springs and cables are still pulling, and the jolt can throw a cable off its pulley. Keep the opening clear and scrape the ice ridge off the threshold before running the door in winter. The second is the opener's force setting. It was set for the newly balanced door; if the door ever seems to need more push, that is the springs asking for attention, not a reason to turn the force up.

What affects the quote

Same fees day, night or weekend

  1. 1Getting the van to the garage

    A detached garage down a shared laneway, a rural property or a building with the bay behind a gate takes more time to reach and set up in, and the quote allows for that.

  2. 2Converting 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.

  3. 3Door weight and size

    Spring rating follows the door's weight, and a wide insulated door or a wood door takes heavier springs than a light single. Weight and height together set the parts on the quote.

Extension Spring Replacement: questions

What are the early signs that the springs are wearing out?

The door starts to feel heavier when lifted by hand and the opener sounds as though it is working harder. Released from the opener, the door sinks from halfway instead of holding. With the door open, gaps show between coils that used to sit tight together, or one spring hangs longer than the other. Rust bloom on the coils and a squeal from a pulley round out the list. Any of these is a good time to call.

What does the paint colour on the end of the spring mean?

Manufacturers dab a colour on the end coil to indicate the spring's weight rating, which is a handy starting point. It is not the final word: a faded or repainted end coil tells you little, and the pair on an older door may have been a near match rather than the right one. The technician treats the colour as a hint and confirms the rating from the door's measured weight and the spring's own dimensions.

Can I use the door as soon as the work is done?

Yes. The last steps of the visit are the balance test by hand, several full cycles under power and the opener's reversal checks, so the door is ready for normal use when the technician leaves. New springs need no settling period. It is worth running it yourself once or twice while the technician is still there, so you know what a properly balanced door sounds and feels like from now on.
