- 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
Garage doors are balanced by one of two spring systems, and the extension kind is the one you find on many single-car doors and older detached garages. Instead of a spring wound on a shaft above the opening, an extension system uses two springs stretched along the horizontal tracks, working through pulleys and cables. It needs less headroom, which is why it suits garages with a low ceiling. Replacing these springs is its own service with its own parts: springs chosen by door weight, pulleys, S-hooks and containment cables. A technician confirms which system is on your door before any part is chosen.

How the visit goes
Scene 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.
Scene 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.
Scene 3
Lubrication that keeps the new set turning
Twice a year, in spring and before winter, a can of garage-door lubricant does most of the maintenance the springs need. Spray a light coat along each extension spring, working from the hanger to the pulley; it slows rust in a damp garage and quiets the coils. Put a drop on each pulley axle and on the bolts through the pulley forks, then on the hinge pins and roller stems. Leave the tracks dry and wipe them clean, since grease there collects grit and stops rollers rolling. Heavy grease and general-purpose oil are avoided on the springs because they hold moisture against the wire. Run the door a few times afterwards to spread the film.

What shapes the quoteErin Mills Garage Door Experts
- 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.
- Getting 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.
- 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.

Answers in plain language
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.
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.
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.

2021 census: what it means at the door
Every square is one home in a hundred.
- 38 in 100 homes · mixed ages
- 37 in 100 homes · mostly attached
- About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.A blend of older and newer homes usually means a blend of expectations too: keeping an original door running as long as sensible, or bringing a builder-grade door up to a quieter standard. Both are worthwhile, and the choice is explained at the door with the options side by side.
- Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Townhouse and condo owners often share responsibility for the door with a board or property manager, so we provide a clear written report after each visit: what was found, what was replaced and what is likely to need attention next, ready to pass along.
