Garage Door Spring Broke in Toronto & the GTA
A sharp bang from the garage and a door that will not lift usually means a torsion spring reached end of life. Treat the system as energized hardware — not a DIY weekend project.
- Leave winding cones alone
- Do not run the opener on a broken spring
- Replace springs as a matched set when worn
- Cycle-rated wire for GTA climate use
What this guide covers
Torsion springs store the energy that makes a heavy door feel light. When a spring breaks, the opener is asked to lift hundreds of pounds it was never designed to carry. That is how gear kits die the same week as the spring.
Upright stocks common wire sizes for Toronto-area doors and replaces springs with proper winding bars, not improvised tools. We also check cables, drums, and bearings while the system is open.
How to recognize a broken spring
You may hear a gunshot-like sound. Visually, look for a gap in the coils on the torsion shaft above the door. Extension springs along the horizontal tracks can show a stretched or separated coil.
- Door suddenly very heavy or immovable
- Opener strains, then stalls or trips
- Visible gap between torsion coils
- Cable slack on one side after the break
Why GTA springs fail when they do
Residential springs are rated for a finite number of cycles. High-use family doors, salt air near highways, and temperature swings all shorten that life. Cheap low-cycle springs fail earlier.

Safe checks vs call a technician
Safe DIY checks
- Disconnect the opener and leave the door closed if possible
- Photograph the spring gap and door brand label for the technician
- Keep kids and pets away from the door opening
- Do not insert screwdrivers into winding cones
Call a professional when
- Any confirmed or suspected spring break
- Extension spring safety cable missing or damaged
- Door that crashed or sits crooked after the bang
- Planning higher-cycle springs for a busy household

Garage Door Spring Broke — common questions
On dual-torsion setups, the mate has seen the same cycles. Replacing the pair keeps balance predictable and avoids a second failure soon after.
No. That overloads the motor and gears. Disconnect the opener and wait for spring service.
Most residential torsion jobs are completed in a single visit once the correct wire size is on the truck.
We discuss usage: a busy family door often benefits from higher-cycle wire than a low-use secondary garage.
