A garage door is one of those household features you only notice when it stops working. In most cases, the culprit behind a door that won’t budge is a broken spring. While it might seem like a simple mechanical part, your garage door springs are actually under extreme tension and are the most dangerous component of your home’s entry system.
For homeowners looking for garage door repair in Mississauga, understanding how these springs work—and why you should never touch them yourself—is essential for your safety and the longevity of your door.
The Hidden Muscle of Your Garage Door
Many people assume the garage door opener does all the heavy lifting. In reality, the opener just provides the signal and a little bit of guidance. The springs do the actual work of counterbalancing the door’s weight, which can range from 150 to over 400 pounds.
When the springs are working correctly, you should be able to lift your door with one hand. When they break, that weight becomes a dead lift, often making it impossible for the opener (or a person) to move the door at all.
Torsion vs. Extension Springs: What’s the Difference?
In most Mississauga homes, you will find one of two types of spring systems. Knowing which one you have can help you describe the problem to a technician from Pro Entry Services.
1. Torsion Springs
These are the most common in modern homes. They are located on a metal shaft directly above the garage door opening. Instead of stretching, they use torque—a twisting force—to lift the door.
- Pros: They last longer (usually 10,000–20,000 cycles) and provide smoother movement.
- Safety: Because they are mounted on a shaft, they generally stay in place if they break.
2. Extension Springs
These are found in older homes or garages with low headroom. They run parallel to the tracks on the sides of the door. They store energy by stretching out like a giant rubber band.
- Pros: Cheaper to install initially.
- Safety: Because they are not on a shaft, they can fly off with dangerous force if they snap. They must have safety cables installed to catch them.
Top 5 Signs You Have a Broken Spring
If you suspect your spring is failing, look for these specific red flags before you try to operate the door again:
- The Loud Bang: A snapping spring often sounds like a gunshot or a heavy object falling. If you heard a loud noise from the garage while you were in the house, it was likely the torsion spring releasing its energy.
- The Gap: A broken torsion spring will have a visible 2-inch gap where it has separated into two pieces.
- Door Only Opens a Few Inches: If the door starts to move but stops after 6 inches, the opener’s safety sensors are likely detecting that the door is too heavy to lift safely.
- Cables Are Frayed or Loose: When a spring breaks, the tension on the cables is lost, causing them to hang loosely from the drums.
- Crooked Opening: If you have two springs and only one breaks, the door will pull to one side, looking crooked as it moves.
The Real Dangers of DIY Spring Repair
We live in an age of YouTube tutorials, but garage door springs are the one project that even the handiest DIYers should avoid. Here is why:
Tremendous Tension
Springs store enough energy to lift a steel door. If a tool slips or you use the wrong winding bar, that energy is released instantly. This can cause broken bones, facial injuries, or worse.
The “Unseen” Second Spring
If you have a double-car garage, you likely have two springs. When one breaks, the other is usually just days or weeks away from failing as well. A professional from Pro Entry Services will know to replace both, ensuring your door is balanced. If you only fix one yourself, you risk the door falling unevenly later that week.

Proactive Maintenance: How to Make Your Springs Last
While every spring will eventually break due to metal fatigue, you can extend their life with a little bit of care:
- Lubricate Twice a Year: Use a silicone-based garage door lubricant on the springs. This prevents rust, which is the #1 cause of premature snapping in the humid Mississauga climate.
- Test the Balance: Once a month, pull the emergency release cord and try to lift the door halfway by hand. If it doesn’t stay in place, your springs are losing tension and need a professional adjustment.
- Listen to the Sound: If your springs are squeaking or “chattering,” it’s a sign of friction. Addressing this early can prevent a sudden break.
Conclusion
A broken spring is more than a nuisance; it’s a safety hazard that leaves your home vulnerable and your car trapped. When the “bang” happens, don’t reach for your toolbox—reach for your phone.
