Your garage door may look simple, but it’s powered by a complex system of springs, cables, and tracks that work together to lift hundreds of pounds safely and smoothly. Among the most essential—and often overlooked—components are garage door extension springs.
In this blog post, we’ll break down what they are, how they work, and why proper maintenance and repair are so important—especially in Ottawa’s tough weather conditions.
What Are Garage Door Extension Springs?
Extension springs are long, tightly wound springs mounted on either side of the door’s horizontal tracks. Their job is to stretch and contract as the door opens and closes, storing and releasing energy that helps lift the heavy garage door.
While torsion springs are more common in newer installations, many Ottawa homes—especially older ones—still use extension springs.
How to Tell If Your Springs Are Failing
Extension springs don’t last forever. In fact, they typically last between 7,000 to 10,000 cycles (one cycle = one full open and close). Here are some signs that your extension springs may need professional attention:
- The door feels unusually heavy or won’t stay open
- It opens or closes unevenly
- You hear loud snapping or banging sounds
- The springs look stretched, rusted, or visibly broken
- The door jerks or shakes when in motion
Safety Tip: Never attempt to fix or replace extension springs yourself. These springs are under high tension and can cause serious injury.
Why Extension Spring Maintenance Matters in Ottawa
Ottawa’s fluctuating weather conditions—especially harsh winters—can take a toll on your garage door system. Cold temperatures may cause metal components to contract and become brittle, making regular inspection and lubrication even more important.
Pro Tip: Have your garage door springs inspected once a year by a professional technician—ideally in the fall before winter hits.
Extension Springs vs. Torsion Springs: What’s the Difference?
| Feature | Extension Springs | Torsion Springs |
|---|---|---|
| Location | Alongside the door tracks | Mounted above the door |
| Motion | Stretch and contract | Twist and untwist |
| Cost | Less expensive | More durable but pricier |
| Lifespan | 7,000–10,000 cycles | 15,000–20,000 cycles |
