Garage Door Spring Types in Aurora: Torsion vs. Extension Explained
2026-08-25 7 min read A2Z Garage Doors
Your garage door relies on one of two spring systems: torsion or extension. Knowing which one you have saves you money, prevents dangerous mistakes, and helps you communicate clearly with repair technicians. Most Aurora homes use torsion springs, but not all, and the difference affects repair costs, longevity, and safety concerns.
What Are Torsion Springs?
Torsion springs sit horizontally above your garage door opening, wound tightly around a metal shaft. When you open the door, these springs unwind, using rotational force to counterbalance the door's weight. They're engineered for precision and durability, lasting 7 to 9 years under normal use. See our guide on garage door photo eye safety in aurora: why this one part matters most.
One snapped spring means the entire system fails instantly. You won't open your door manually without serious risk. That's why a snapped spring demands immediate professional repair, not a DIY patch job.
Torsion springs cost more to replace than extension springs, typically ranging from $200 to $400 per spring plus labor. But they're worth it. They distribute weight more evenly, put less stress on your opener, and rarely fail suddenly if you catch early warning signs. Read about garage door springs in aurora: when they fail & how to spot warning signs.
What Are Extension Springs?
Extension springs run horizontally along both sides of your door opening, stretching and contracting as the door moves. They're simpler, cheaper to install, and common in older homes and some budget installations across Aurora and surrounding areas.
The trade-off? Extension springs wear out faster, around 5 to 7 years. When one fails, you still have the other as a backup, giving you a narrow window to call for help before the second one snaps. That backup saves you from complete lockout, but don't ignore it.
Extension springs also transfer uneven stress to your opener and door tracks over time. Repeated imbalance causes misalignment, damaged rollers, and premature opener failure.

How to Tell Which Type You Have
Look above your garage door from inside the garage. Torsion springs run horizontally across the top center, usually with cables attached to both ends. They're thick, wound tightly, and look industrial. Extension springs run vertically along the top sides, stretching lengthwise. They look thinner and less compact.
If you can't safely access the space, don't force it. Call a technician for a free visual inspection. Garage Door Company Aurora can identify your system and explain repair options without pressure.
Why This Matters for Your Wallet
Understanding your spring type prevents overpaying for unnecessary work. If a contractor quotes you $600 for a single extension spring replacement, you're being overcharged. If they recommend replacing both springs on a torsion system when only one is damaged, ask why before agreeing.
Preventive maintenance extends spring life. Regular lubrication and balance testing catch wear early. We've written a full maintenance guide that explains lubrication schedules and testing steps so you can stay ahead of failures.
When to Replace vs. Repair
Spring repair isn't really an option. Springs don't get "fixed." They get replaced. Once a spring snaps or loses tension, replacement is your only choice. That's why knowing your spring type matters for budget planning.
If your door opens unevenly or pulls to one side, it's often a spring balance issue, not a complete failure yet. Read our guide on warning signs to spot before springs fail completely and you'll know when to act.

Regional Considerations for Aurora
Aurora winters are brutal on springs. Temperature swings cause metal to contract and expand repeatedly. Springs in Colorado Springs and Denver suburbs fail earlier than springs in milder climates. If your springs are past the 6 to 7 year mark and you're in Aurora, start budgeting for replacement even if they haven't failed yet.
Salt and moisture from snow melt also corrode spring hardware faster. Regular lubrication with garage-door-specific products prevents rust and extends life by 1 to 2 years.
Springs don't last forever, but you can control when they fail. Knowing your type, catching warning signs early, and scheduling preventive maintenance keeps you safe and saves money. Don't wait for a snapped spring to strand your car inside.

Frequently Asked Questions
Can I replace one spring if I have two? No. If one spring fails, the other is near the end of its life. Replacing both prevents immediate repeat failure and ensures balanced door operation. Replacing one leaves you vulnerable to a second break within weeks.
How much does spring replacement really cost in Aurora? Torsion spring replacement ranges from $200 to $400 per spring plus labor. Extension springs cost $150 to $250 per spring plus labor. Labor typically adds $100 to $200. Get multiple estimates before committing.
Is it safe to use my garage door if one spring is broken? No. A snapped spring removes the counterbalance system. The door becomes extremely heavy, dangerous to open, and risks crushing fingers or objects. Call a professional immediately.
How often should springs be replaced? Torsion springs last 7 to 9 years. Extension springs last 5 to 7 years. Aurora's temperature swings and winter salt can shorten this by 1 to 2 years. Annual inspections help catch wear early.
What's the difference in maintenance between spring types? Both types benefit from regular lubrication and tension testing. Torsion springs need less frequent adjustment but cost more to replace. Extension springs need more frequent monitoring but cost less upfront.
