Torsion vs. Extension Springs in Oakville: Which Type Do You Have?
2026-09-12 7 min read
In our years serving Oakville, we've seen homeowners confused about their garage door springs until something breaks. The type matters enormously. Torsion springs sit above your door and twist to lift weight. Extension springs run along the sides and stretch open. Most homes use one or the other, but knowing which one you have prevents dangerous mistakes and helps you understand repair costs faster.
Why Spring Type Matters for Safety
This isn't just technical trivia. A snapped spring is one of the most dangerous garage door failures. Torsion springs store tremendous rotational energy. Extension springs hold tension along cables. When either fails, the door can drop unexpectedly, pinching fingers, crushing objects, or worse. You cannot safely replace either type yourself. The tension is too high.
Oakville homeowners who understand their spring type are less likely to attempt DIY fixes. That's the safety win we care about. Knowing what you have also lets you describe the problem clearly to a technician, which speeds diagnosis and gets you a same-day estimate faster.
Torsion Springs: How They Work
Torsion springs mount horizontally above your garage door opening, usually on a steel rod. As your door closes, the spring tightens. As it opens, the spring unwinds. This rotational motion is what counterbalances the door's weight.
Most newer homes and heavier doors use torsion springs. They're more durable, last 7 to 9 years under normal use, and wear more evenly than extension springs. When a torsion spring fails, the door becomes nearly impossible to open manually. Many people hear a loud bang when the spring snaps.
Torsion springs come in different gauges and winding directions. The cost of replacement depends on door weight, spring length, and quality grade. A detailed garage door spring replacement cost breakdown in Oakville can help you understand pricing upfront.
Extension Springs: How They Work
Extension springs run parallel to your garage door tracks, one on each side. They stretch as your door closes and contract as it opens. This extension and contraction counterbalances the door weight.
Older homes and lighter doors often use extension springs. They're less expensive upfront but wear faster than torsion springs, typically lasting 5 to 7 years. Extension springs also require safety cables running through them. If a spring snaps, the cable prevents the spring from whipping across your garage, which is a genuine injury hazard.
When an extension spring fails, the door often tilts or moves unevenly. Some homeowners notice the door won't open at all on one side.

How to Identify Your Spring Type
Stand inside your garage with the door closed. Look above the door opening at the ceiling. Do you see a horizontal steel rod running left to right with a coil wrapped around it? That's a torsion spring system.
Do you see springs running vertically along each side of the door tracks? Those are extension springs. Extension springs look like compressed coils attached to the door frame via brackets and pulleys.
When you call for service, describe what you see. A technician can also identify your spring type from a photo. This speeds up the process and helps us provide accurate pricing.
Spring Failure: Common Warning Signs
Don't wait until a spring snaps. Listen for these warning signs. A creaking sound during opening or closing often means the spring is wearing unevenly. If your door feels heavier than usual, a spring may be losing tension. If the door moves slowly or jerks, spring failure is near.
Our garage door maintenance guide covers inspection routines that catch spring wear early. Regular lubrication and inspection can extend spring life and prevent sudden failure.
Replacement Cost and Spring Lifespan
Torsion spring replacement typically costs more than extension spring replacement because the work is more complex and requires specialized tools. Both types need professional installation. A snapped spring near me search in Oakville will show why: this isn't a DIY job.
Spring cost varies by weight rating, material quality, and labor. A free estimate from a local technician gives you real numbers. Most Oakville homeowners pay between $200 and $400 per spring, plus installation.

Frequently Asked Questions
What happens if a garage door spring breaks while the door is open? The door will drop suddenly if no other support holds it. This is why safety cables are essential on extension springs. Torsion spring failure while the door is open can cause the door to fall and damage the opener or track.
Can I replace just one spring if one snaps? No. Springs wear as a pair. If one fails, the other is near failure. Replacing only one causes uneven lifting and premature damage to the opener and door. Professional technicians always replace both springs together.
How often should garage door springs be inspected in Oakville? Annual inspection is ideal. If you use your door frequently, twice yearly catches wear early. Many homeowners skip this until something breaks, which costs more in the long run.
What's the difference in cost between torsion and extension spring repair? Torsion springs typically cost $150 to $250 per spring, while extension springs range from $100 to $150 per spring. Labor varies, but professional installation is required either way.
How long do garage door springs last before needing replacement? Torsion springs last 7 to 9 years under normal use (about 10,000 cycles). Extension springs last 5 to 7 years. Frequent use shortens lifespan. Regular maintenance and lubrication extend durability.
