Garage Door Spring Repair

A garage door can weigh as much as a hundred pounds or more. Springs counterbalance that weight so the opener, or your hand, only has to guide the door rather than lift it. Torsion springs sit horizontally above the door on a steel shaft, while extension springs run along the side tracks.

Each time the door cycles, the spring winds and unwinds. Over many cycles the metal fatigues and eventually breaks. Springs are rated by cycles, so heavier use or a heavier door shortens their life.

Most modern residential doors use torsion springs, which are generally quieter and longer lasting. Older or smaller doors often use extension springs along the side tracks, usually with safety cables running through them.

Both types must match the door's weight and height. A spring that is too light fails early, and one that is too strong over-lifts the door and stresses the cables. Many older homes in Hamilton and Brantford still have extension systems, and in many cases they can be converted to torsion.

The classic sign is a loud bang from the garage when a spring snaps. Afterward the door feels very heavy, will not stay open, or the opener runs but the door barely moves. A visible gap in the coil above the door confirms it.

Before a spring breaks, you may notice the door moving unevenly, dropping when lifted partway, or the opener straining more than usual. These are good reasons to book an inspection.

A technician first confirms the spring type and identifies why it failed. We measure the door and select the right wire size, length and cycle rating rather than using the nearest part on the truck. You receive a written quote and approve it before work begins.

We use winding bars and proper hardware to install and set tension, usually replacing both springs together, then check cables, drums and brackets. The door is balanced and tested through full travel before we leave.

Spring work involves stored energy that can cause serious injury if released uncontrolled. Improvised tools such as screwdrivers or pliers are a common cause of accidents. This is not a repair to attempt at home.

If you think a spring has broken, leave the door closed, disconnect the opener if you can do so safely, and keep people and pets clear. Do not force the door open or run the opener repeatedly.

We replace springs in Hamilton, Burlington, Oakville, Brantford and Waterdown. Double-car doors are common in newer Burlington, Oakville and Waterdown subdivisions and need heavier springs and hardware, which we carry on our trucks.

Cold Ontario temperatures can add stress to steel springs, so a door that has been showing wear may fail when the weather turns. Same-day service is available in many cases.

Call right away if you hear a bang, the door feels heavy, or it will not stay open. A door with a broken spring is unsafe to operate and can damage the opener.

If you only notice wear, such as noise or uneven movement, schedule a visit before the spring fails. Replacing it on your schedule is far easier than dealing with a car trapped in the garage.

Expect a clear explanation of the problem, a written quote, and replacement of both springs where it makes sense so you avoid a second visit soon after.
