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.

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.
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.
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
What you have afterwards is a door that behaves like a much lighter object. Both corners leave the floor together, the door holds still when you stop it at waist height, and it settles onto the floor instead of slamming. The opener runs quietly, because it is guiding a balanced door rather than hauling a heavy one, and its safety reversing works as designed. Both springs are new, both carry a containment cable, the pulleys turn freely and both S-hooks sit in the same hole. You also get the spring rating and door weight written down, so the next set can be ordered without measuring everything again.
How the visit goesYou 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. It used to float up with one hand.

How the visit goes
- 1
Weighing the door
Extension springs are chosen by the weight they are built to lift, so the door is weighed rather than guessed at. With the opener released and the springs disconnected or slack, the technician lowers the door onto a scale set on the floor under the bottom section and reads the figure. That number, together with the door's height, sets the spring rating and stretch length. The old springs are measured as a cross-check, but the scale wins if the two disagree, because a door can gain weight from new panels, insulation or a cladding added since the springs went on.

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.

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.

What affects the quote
- 1
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.
- 2
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.
- 3
Door 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 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.
How long do extension springs last?
Springs are rated in cycles, one cycle being a full open and close, and a standard set is built for a number in the ten-thousand range. A door used four times a day gets through that in several years; a door used a few times a week takes far longer. An unheated, damp garage shortens the figure through rust. Regular lubrication and a door kept in balance stretch it out.
How do you know which springs my door needs?
By weight. Extension springs are rated for the weight they lift, so the technician releases the opener and weighs the door on a scale, then matches that figure and the door's height to a spring rating and stretch length. The old springs are measured as a check on wire size, coil diameter and length. Where the two disagree, the scale decides, since doors gain weight from added insulation or panels.

What the census means at the door
52%
Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.
Older houses frequently have a garage door that was replaced once already, sometimes with a door chosen for the opening rather than the building. When that door reaches its end, there is a chance to pick a style that suits the house properly, and we measure with that in mind.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In a neighbourhood with both detached and attached homes, some customers decide alone and others report to a board or property manager. We adapt the visit accordingly, giving a homeowner options at the door and a manager a written summary they can circulate.
