Garage Door Spring Replacement in Calgary – What Every Homeowner Needs to Know
One of the most common calls we receive at Alberta Garage Door Services is from homeowners whose garage door suddenly stopped working — and the culprit is almost always a broken spring. In fact, garage door spring replacement is one of the most frequent repairs in Calgary and across Alberta. If you’ve ever heard a loud bang from your garage late at night, chances are a spring has snapped.
In this post, we’ll explain everything you need to know about garage door springs — how they work, why they fail, the difference between spring types, and why you should never attempt to replace them yourself.
What Do Garage Door Springs Actually Do?
Your garage door may weigh anywhere from 100 to 400 kilograms depending on its size and material. Without springs, your garage door opener motor would struggle enormously — or fail completely — trying to lift that weight every time you pressed the button.
Garage door springs act as a counterbalance system. They store mechanical energy when the door closes and release that energy to assist the opener — and in some cases your own physical strength — when raising the door. In short, springs do the heavy lifting so your motor doesn’t have to.
The Two Types of Garage Door Springs
There are two primary types of garage door springs used in residential and commercial systems across Calgary:
Torsion Springs are mounted horizontally above the garage door opening along a steel shaft. When the door closes, the spring winds up tightly, storing energy. When the door opens, the spring unwinds and assists in lifting. Torsion springs are more durable, produce a smoother and quieter operation, and are considered safer because they break in a controlled manner. Most modern homes in Calgary have torsion spring systems.
Extension Springs run along the horizontal tracks on either side of the door. They stretch and contract as the door moves. Extension springs are common in older homes and tend to be less expensive upfront, but they require safety cables to prevent them from becoming dangerous projectiles if they snap.
Why Do Garage Door Springs Break?
Springs are not designed to last forever. They have a cycle rating — typically between 10,000 and 30,000 cycles depending on quality. One cycle equals one full open-and-close of the door. If your family uses the garage door four times a day, that’s 1,460 cycles per year — which means a standard spring set could last roughly seven to ten years.
Alberta’s extreme cold also accelerates spring fatigue. Low temperatures make metal more brittle, increasing the risk of snapping during winter months. That’s one reason we see a significant spike in emergency garage door repairs in Calgary every January and February.
Other factors that shorten spring life include lack of lubrication, excessive door weight from added insulation or decorative hardware, and poor-quality springs from budget installations.
Signs Your Garage Door Springs Are Failing
Don’t wait for a complete snap. Watch for these warning signs:
Your garage door feels unusually heavy when you try to open it manually. If your door lifts with ease when disconnected from the opener, the springs are likely still working. If it’s very heavy or doesn’t stay up on its own, the springs are failing.
Your door opens unevenly or is crooked. One spring may have lost tension while the other remains strong, causing the door to tilt to one side.
Your opener is straining. If the motor sounds like it’s working harder than usual, or if it starts and then reverses immediately, a weakened spring may be the cause.
You can see visible gaps in a torsion spring. A snapped torsion spring will have a visible separation or gap in the coil.
The door closes faster than usual and hits the ground with a loud bang — a sign that the springs are no longer providing proper resistance.
Why This Is NOT a DIY Repair
We cannot stress this strongly enough: garage door spring replacement is one of the most dangerous DIY repairs a homeowner can attempt. Torsion springs are wound under enormous tension. If released incorrectly, they can cause severe injuries, broken bones, or even fatality. Every year, Canadians are seriously injured attempting to replace garage door springs without proper training and tools.
Professional technicians use specialised winding bars, safety equipment, and calibrated tools to safely manage spring tension. Attempting this with a screwdriver or makeshift tools is genuinely life-threatening.
What to Expect From a Professional Spring Replacement
When you call Alberta Garage Door Services for a spring replacement in Calgary, here’s what happens:
Our technician will arrive, inspect your entire door system, and identify the spring type, size, and required tension. We’ll replace both springs simultaneously — even if only one has broken. Replacing springs in pairs ensures balanced tension, extends the life of both springs, and saves you from calling again in a few months when the second spring inevitably fails.
We also lubricate all moving parts, check cable condition, test the opener, and ensure the door is properly balanced before leaving. The whole process typically takes about one hour.
How Much Does Garage Door Spring Replacement Cost in Calgary?
Pricing varies based on spring type and size, but here’s a general guide:
- Single torsion spring replacement: $150–$250
- Double torsion spring replacement: $200–$350
- Extension spring replacement (pair): $120–$200
- Emergency/after-hours service: may include an additional call-out fee
These prices include parts and labour. We use high-cycle springs rated for 20,000+ cycles for maximum longevity.
Act Quickly – Don’t Operate a Door With a Broken Spring
If your spring has snapped, do not continue operating the door with the opener. Doing so can burn out the opener motor, damage the cables, and create additional safety hazards. Disconnect the opener and avoid using the door until a professional has made the repair.
