- The call
- 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.
It is the first hard frost of the year and the door on the old detached garage has stopped halfway, squealing at one pulley. The springs are the ones that came with the door decades ago, orange with rust where they hang near the back wall.
In plain words
When one extension spring breaks, the other is replaced with it. The two springs were fitted together, have stretched the same number of times and have rusted in the same air, so the survivor is near the end of its life. More importantly, a door balances only when both sides pull equally; a new spring paired with a tired one lifts one corner ahead of the other and twists the door. Fitting a matched pair rated for the door's weight lets the technician set both sides to the same hook position and hand back a door that rises level and holds where it is left.

How the visit goes
Scene 1
Hangers, brackets and what they are screwed into
Extension springs pull against whatever holds their back end, usually an angle-iron hanger bolted to the rear track support or lag-screwed into a ceiling joist. The technician checks that this anchor is tight, that the lag screws bite into wood rather than drywall or a split joist, and that the hanger has not bent under years of load. The bracket that carries the fixed pulley at the front of the track is checked the same way, along with the bottom brackets on the door that the lift cables pull on. An anchor that has loosened lets the spring's geometry drift, which is one reason a door slowly becomes uneven.
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
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 shapes the quoteBridgeport Garage Door Experts
- 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.
- How the door is sitting
- A door resting closed with one spring gone is straightforward. A door stuck partway, twisted in its tracks or with a cable wrapped around a pulley has to be supported and straightened first.
- 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.

Ask us anything
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.
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.
Only one spring broke. Why replace both?
The two springs are the same age and have stretched the same number of times, so the one still hanging is close behind. There is also a balance reason: a door lifts level only when both sides pull equally, and a new spring beside a worn one lifts its corner first and twists the door. Fitting a matched pair sets both sides the same and avoids a second visit a few months on.

2021 census: what it means at the door
Every square is one home in a hundred.
- 49 in 100 homes · mixed ages
- 48 in 100 homes · mixed housing
- About 49% of homes in Kitchener were built in 1980 or earlier, according to the 2021 Census.Mixed neighbourhoods often include renovated older houses with a new facade and a garage door that no longer suits it. Choosing a door that ties the renovation together, then installing it plumb and balanced in an older opening, is work we do regularly and enjoy.
- Single-detached houses make up about 48% of homes in Kitchener (2021 Census).A mixed neighbourhood is where weatherproofing varies most. A detached garage with an old, uneven apron needs a thicker bottom seal; a newer townhouse door mostly needs a cracked section of seal replaced. We look at how each door meets its floor and fit what closes the gap.
