Broken Garage Door Springs in Mount Prospect
Spring calls here rarely start subtly. Something lets go with a bang in the garage, and the next time anyone presses the button the door lifts three or four inches and stops dead.

The springs carry the weight of the door, not the opener. Once one has parted, the motor is dragging a couple of hundred pounds of steel up the track on its own, which is how a spring failure quietly turns into an opener failure a few weeks later.
A Heavier Door Needs a Different Spring
A lot of the ranches and split-levels around Mount Prospect have had their original single-skin steel door swapped for an insulated one. The new door seals better and looks right on the street, but it can weigh half as much again as the one it replaced.
If the spring was carried over during that swap, it has been under-rated for the job ever since. You see it in a door that will not hold halfway, an opener that groans on the way up, and springs that give out years earlier than they should. Sizing the spring to what the door actually weighs is the fix, and it is the first thing the technician checks.
Torsion Above the Opening, Extensions Along the Track
Doors in the village run one of two systems. Torsion springs sit on a shaft above the opening and are the normal fit on wider or heavier doors. Extension springs stretch along the horizontal tracks on either side and turn up mostly on older narrow singles that were never upgraded.
Extension springs need a containment cable threaded through them. On garages built in the fifties and sixties that cable is often missing, because it was not always fitted at the time. Without it, a spring that snaps becomes a length of steel travelling across the garage. When we replace extension springs, the containment cables go in with them.
What Happens on the Visit
Wire gauge, inside diameter and overall length come off the old spring before anything else, and the door gets weighed if there is any doubt. A spring that is nearly right will run the door heavy and wear out early, so the measuring is not a formality.
New springs go on as a pair where the door has two, the shaft is wound to suit the weight, and the door is balanced by hand until it stays put wherever you leave it. Cables, drums, end bearings and the opener force settings all get looked at in the same visit, because a spring seldom breaks without leaving marks elsewhere in the system.

Questions
Mount Prospect questions about this job
How long should springs last on a door the family uses every day?
Springs are rated in cycles, one cycle being one open and one close. Around 10,000 is standard, which works out at roughly seven to ten years for an average household. In a house where the garage is the door everyone actually walks through and the car leaves early and returns late, that total arrives sooner.
Can extension springs be converted to a torsion setup?
Often, yes, provided there is enough headroom above the opening for the shaft. Torsion wears more evenly, holds balance better and keeps the hardware clear of the ceiling. The technician measures the headroom on site and gives you a straight answer either way rather than assuming.
The spring that did not break looks rusty. Does that matter?
Rust matters more than it looks. A corroded coil binds against itself instead of sliding cleanly, which accelerates metal fatigue and changes how the spring winds. If one has already gone and the survivor is corroded, doing the pair is the sensible call.
Is spring replacement a reasonable weekend job?
No. A wound torsion spring stores enough energy to break bones, and setting one properly needs winding bars and the correct number of turns for that specific door. It is the one repair on a garage door we would tell anyone to leave alone.
