Broken garage door spring replacement in Durham Region
A snapped spring is the single most common reason Durham Region homeowners call a garage door company. Most people describe the same thing: a bang loud enough to be heard from inside the house, then a door that feels impossibly heavy and an opener that hums without lifting anything. The springs, not the motor, carry the weight of the door, so once one lets go the whole system stops working.
Springs are rated in cycles rather than years. A standard residential spring is built for roughly ten thousand open-and-close cycles, which a busy family can use up in six or seven years, and Ontario winters shorten that further as cold steel becomes less forgiving. We stock a wide range of torsion springs and also service older extension-spring systems, sizing the replacement to your door's actual weight, height and drum type rather than fitting whatever happens to be on the shelf.

Signs your spring has failed or is about to
Spring failure is sudden, but the warning signs usually appear weeks earlier. If you notice any of the following, stop using the door and call before it fails completely.
- A gap of two or three inches in the coil above the door, the clearest sign a torsion spring has broken.
- The door rises only a few inches then stops, or the opener strains and reverses immediately.
- The door feels extremely heavy by hand and crashes down instead of staying where you leave it.
- Rust, elongated coils or a spring that looks stretched compared with its partner on the same shaft.
How spring replacement is done
Spring work is the highest-risk job on a garage door, and it follows a strict sequence for good reason.
- 01We measure wire diameter, inside diameter, length and wind direction, then weigh the balance requirement so the replacement matches your door exactly.
- 02Remaining tension is released with proper winding bars while the door is secured, and old springs, cones and bearings are removed.
- 03New springs are installed with fresh centre and end bearings where needed, cables are re-seated in the drums and tension is wound to the correct turns.
- 04The door is balance-tested by hand at knee, waist and shoulder height, the opener force is re-set and the safety reverse is verified.
Why spring work is not a do-it-yourself job
- A wound torsion spring holds hundreds of pounds of stored energy. Released without proper bars, it moves faster than anyone can react.
- Springs must be matched to door weight. An incorrect wire size leaves a door that drifts, slams or wears out its opener within months.
- On two-spring doors, replacing both at once prevents an unbalanced load and a second call weeks later when the older spring follows.
Residential and commercial spring service
Residential doors typically use one or two torsion springs above the opening. Commercial bays and shop doors often use high-cycle springs rated for twenty-five thousand cycles or more, and for businesses that open a door dozens of times a day the upgrade usually pays for itself. Tell us your door type and daily usage when you call and we will bring the right springs for the job.

support@anygaragerepair.caOn a two-spring door we strongly recommend it. Both springs have the same cycle history, so the second is usually close behind. Replacing the pair keeps the door balanced and avoids paying for a second service call within the year.
