Extension Spring Work on Schaumburg Garages
Stand inside the garage and look up. If a long spring runs along each horizontal track, stretched out parallel to the ceiling and hooked to a pulley, you have extension springs. If instead there is a steel shaft across the wall above the opening with a coil wound onto it, that is a torsion system and a different repair entirely.

Extension springs still show up around Schaumburg on lighter doors. Original single-car openings from the early build-out have them, and so does any garage where there was never enough clearance above the header for a torsion shaft. They are a perfectly sound design. They simply wear and fail in their own way.
How an Extension Spring Gives Up
Extension springs stretch before they break. The coil takes a permanent set, the spring no longer returns to its resting length, and it stops pulling its share. Because the two sides rarely fatigue at exactly the same rate, the door starts lifting unevenly and the rollers scrub in the track.
The spring is also only one part of an assembly. Each side has a pulley, a lift cable, S-hooks and an anchor at the rear track hanger. Replacing a tired spring while leaving a grooved pulley or a frayed cable in place only relocates the next failure, so we quote the assembly rather than the coil on its own.
Containment Cables Are Part of the Job
An extension spring under load stores real energy along its length. When one snaps, that energy releases sideways, and the loose spring and hardware travel. The engineering answer is a containment cable threaded down the centre of the spring and anchored at both ends, so a broken spring is captured rather than launched.
Older installations around the village very often have none, or have one on a single side. Every extension spring we replace gets a containment cable fitted, whether or not the door had one before. There is no scenario where it is the wrong call.
Stay With Extension, or Convert to Torsion
If the door is light, the tracks are straight and the headroom is genuinely tight, replacing like for like is the honest recommendation and we will say so. Extension springs work.
Conversion earns its keep in two situations: a heavier insulated door that was hung on an extension system never intended for the weight, and a garage where the horizontal tracks and the springs above them are constantly in the way of storage. A torsion shaft balances a wide door more evenly and keeps the hardware in one place above the opening. Where headroom is the obstacle, low-headroom torsion kits exist and we will measure to see if one fits before suggesting it.

Questions
Schaumburg questions about this job
What is the practical difference between extension and torsion springs?
Extension springs pull along the horizontal tracks and work as two independent units. A torsion spring sits on a shaft above the opening and twists, driving both cable drums from one point. Torsion gives smoother balance on wide, heavy doors. Extension needs less headroom and suits lighter doors.
Do both extension springs need replacing if only one broke?
Yes. The two sides have carried identical loads for identical years, so a fresh spring opposite a fatigued one pulls harder and racks the door in the opening. Fitting both together keeps the lift even and avoids a repeat callout when the second one goes.
There is barely any clearance above my garage door. What are my options?
Low-headroom situations are common in the older detached and tuck-under garages here. Options include staying with extension springs, a low-headroom torsion kit with a double horizontal track, or a rear-mount torsion arrangement. The technician measures the clearance above the header and the depth behind the opening before recommending anything.
