Garage Door Springs in Ontario: Torsion vs. Extension Explained
2026-08-25 7 min read
Your garage door relies on one of two spring systems to lift a 300 to 400 pound panel. Understanding which type you have, and how each works, cuts through confusion and helps you avoid overpriced repairs. We'll walk you through both so you know what to expect when you call for an estimate.
Torsion Springs: The Workhorse
Torsion springs sit horizontally above your garage door opening, wound around a steel shaft. When the door closes, the spring winds tighter, storing mechanical energy. That tension releases when you open the door, counterbalancing the weight so your opener doesn't strain.
Torsion springs are more durable and quieter than their counterpart. They typically last 7 to 9 years with normal use, handling thousands of cycles before fatigue sets in. Most modern residential doors use torsion springs because they're precise, safer, and distribute load evenly across the shaft.
The tradeoff: if one snapped spring fails, the entire door becomes unbalanced. A snapped spring on a torsion system means the door won't open or close smoothly, and forcing it risks damage to your opener and tracks.
Extension Springs: The Secondary Option
Extension springs run vertically along each side of your door opening. They stretch and contract to counterbalance weight, much like a rubber band under tension. Older homes and lighter doors often use these.
Extension springs wear faster because they're exposed to direct stress with every cycle. They also require safety cables running through them. If an extension spring fails without a cable in place, the spring can whip across the garage, creating a serious safety hazard.
Installation and repair of extension springs is typically less expensive than torsion work, but their shorter lifespan (5 to 7 years) means you'll replace them more frequently. For homeowners in Ontario looking for longevity, torsion is the better long-term choice, even if the upfront cost is slightly higher.
Why Springs Snap and When to Call
Springs fail due to metal fatigue. Each opening and closing cycle stresses the coil. After thousands of cycles, micro fractures develop. Temperature swings in Ontario's climate don't help, as metal contracts and expands with heat and cold, accelerating wear.
You'll know a spring is failing before it snaps completely. Listen for a loud bang or crack when the door operates. If the door feels heavier or slower to open, or if it tilts to one side, a spring is likely weakening. Don't ignore these signs. A failing spring can snap without warning, leaving you stuck.

Cost and Honest Pricing
A torsion spring replacement typically runs $200 to $400 per spring, including labor and parts. Extension springs cost $100 to $250 per spring. The difference reflects complexity: torsion work requires precise calibration and specialized tools.
We've seen homeowners quoted $800 to $1200 for a single spring replacement elsewhere in Southern California. That's inflated. At Garage Door Company Ontario, we charge fair prices and explain exactly what's needed before we touch your door.
Getting an accurate estimate requires an in-person look at your system. Spring size, door weight, and local labor rates all factor in. If you're comparing quotes, ask each company what's included: do they replace both springs (recommended for wear balance), adjust tension, and test the door's balance afterward? Cheap quotes that skip these steps will cost you more in repairs down the road.

Prevention and Maintenance
You can't stop springs from aging, but you can slow the process. Regular maintenance keeps springs, tracks, and rollers in good condition. We recommend a tune-up every 6 to 12 months. A technician will lubricate moving parts, check tension, and spot wear before failure happens.
If you've never had your springs serviced, or if your door is over 5 years old, a professional inspection is worth the peace of mind. A small maintenance visit costs far less than an emergency call for a snapped spring.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use, about 10,000 cycles. Extension springs wear faster, lasting 5 to 7 years. Frequency of use, climate, and maintenance all affect lifespan. If your door opens and closes multiple times daily, expect shorter service life.
Can I replace a garage door spring myself? Not recommended. Springs are under extreme tension and can cause serious injury if mishandled. A technician has proper tools, safety equipment, and training. DIY attempts have caused broken bones and lacerations. Always call a professional.
Why did my spring snap without warning? Springs fail from metal fatigue, not sudden impact. Micro fractures develop over years of stress and temperature cycles. You usually get warning signs: unusual noise, sluggish operation, or visible rust. If you ignore these, a snap can happen anytime.
Should I replace both springs even if only one snapped? Yes. When one spring fails, the remaining spring has handled unbalanced load for months or years. Replacing both ensures even wear and balanced operation going forward. It costs slightly more upfront but prevents a second failure weeks later.
What's the difference between repair and replacement? A repair adjusts or fixes a spring that's still functioning but worn or misaligned. Replacement removes the old spring and installs a new one. If a spring is snapped or severely rusted, replacement is necessary. Our technician will recommend the right option after inspection.
