- The call
- 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. It used to float up with one hand.
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.
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
Containment cables, present or missing
The question the industry's own inspection checklist asks of every extension-spring door is whether each spring has a cable running through its centre, anchored at both ends. The technician checks for it on both sides, then checks its condition: a cable that is frayed, kinked, anchored to a loose screw or simply tied off to the hanger is not doing its job. Doors installed decades ago often have none at all, and doors that had a spring changed by a previous owner sometimes have one side fitted and one forgotten. Fresh containment cables go on with the new springs, and their anchor points are set into solid framing so that a spring which breaks stays on its cable.
Scene 2
Renewing the hardware around the springs
Anything the inspection flagged is dealt with while the door is open and the springs are slack, because that is when the work is easiest and the parts are already in hand. A pulley with a grooved wheel or a stiff bearing is swapped for a new one on its fork or bracket. Lift cables with rust at the loop or broken strands are replaced along with the springs. A rear hanger that had loosened is re-fixed with lag screws into a sound joist, and a bent front bracket is straightened or renewed. Bottom brackets eaten by salt and rollers with cracked wheels are changed at the same time.
Scene 3
Knowing when the next set is due
A standard extension spring is made for a set number of open-and-close cycles, commonly in the ten-thousand range, which on a door used four times a day works out to several years and on a door used twice a week to much longer. Springs age even when idle, as rust does its slow work in an unheated garage. The signs that the set is nearing the end are gradual: the door feels heavier by hand, the opener sounds as if it is working, the door drifts down from halfway, and gaps appear between coils when the door is open. Acting on those signs turns the next replacement into a planned appointment rather than a bang in the night.

What shapes the quoteMount Nemo Door Specialists
- Pulleys that need renewing
- Each side has two pulleys, and a wheel worn to a groove or a bearing that has stiffened is replaced with the springs. The quote names how many and which type.
- 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.
- 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.

Answers in plain language
Could I switch to torsion springs instead of replacing the extension ones?
Sometimes, and it is worth asking. A torsion system needs room above the door opening for its shaft and a header that can carry the spring bracket, which many older garages with a low ceiling simply lack; extension springs are there for that reason. Where the headroom exists, a conversion is a separate job with its own hardware and quote. The technician can tell you on the spot which route suits your garage.
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.
Should I try to open the door by hand before the technician arrives?
No need, and it is easier on the door if you leave it. With a spring broken or slack, the door is unbalanced and heavy, and lifting it can let it drop or twist a section in the track. If the door is stuck partway, leave it there and keep people and the car away from the opening. The technician brings clamps and props, and the door is secured before it is moved at all.

2021 census: what it means at the door
Every square is one home in a hundred.
- 61 in 100 homes · older homes
- 56 in 100 homes · mixed housing
- About 61% of homes in Hamilton were built in 1980 or earlier, according to the 2021 Census.Original openers in older neighbourhoods often predate photo-eye sensors and rolling-code remotes. Bringing one up to date means a quieter motor, sensors that stop the door for a child or pet, and remotes that cannot be copied from the driveway, all installed in a single visit.
- Single-detached houses make up about 56% of homes in Hamilton (2021 Census).Where housing types are mixed, some doors belong entirely to the homeowner and others are subject to a condo corporation's rules on colour and style. Before recommending a replacement door we ask who has a say, so the door chosen is one that can actually be installed.
