Torsion vs. Extension Springs in Rhododendron: Which Type Do You Have?
2026-07-11 7 min read
Your garage door springs are working right now, even if you can't see them. The moment a snapped spring happens, you'll understand why knowing the difference between torsion and extension types matters for your wallet. Most Rhododendron homeowners don't realize they have a choice, or worse, they assume all springs cost the same. They don't.
What's the Actual Difference?
Torsion springs sit above your garage door, running horizontally across a metal rod. They twist and unwind to lift the door. Extension springs hang on both sides of the door track. They stretch and contract like rubber bands. That's not just a design quirk. It affects cost, lifespan, safety, and repair complexity.
Torsion springs typically last 7 to 9 years with normal use. Extension springs last slightly longer, around 8 to 10 years. But here's where budget matters: torsion springs cost more upfront (usually $200 to $400 per spring installed), while extension springs run $150 to $300. However, torsion springs are generally safer and more durable. If you're replacing springs now, understanding which type you have prevents overpaying or choosing the wrong replacement.
Safety First: Why This Matters
Extension springs have safety cables running through them. Without those cables, a snapped extension spring can whip across your garage like a projectile. That's dangerous. Torsion springs are contained above the door, making them inherently safer, though still requiring professional handling. Both types store enormous tension. A snapped spring isn't just an inconvenience. It's a repair that demands professional help.
If you've never seen your springs fail, you might think they last forever. They don't. When one fails, the other usually follows within months because both carry equal load. Replacing just one spring now can mean a second service call and bill down the road. Many homeowners try to save money by replacing one, then regret it when the second snaps during a family vacation.

Which Type Do You Actually Have?
Look above your garage door from inside the garage. If you see a thick metal rod running horizontally with springs coiled around it, you have torsion springs. If you see springs hanging vertically on each side of the door track, those are extension springs. This matters because you can't mix types. You need to replace with the same kind your door was designed for.
Not sure? That's fine. A quick photo and a call to our team at Garage Door Rhododendron gets you a real answer. We'll assess your setup, tell you exactly what you're working with, and give you an honest estimate without pressure. Many homeowners in the Mt. Hood corridor discover their springs are older than they thought and benefit from understanding their options before something breaks.
Cost Breakdown: What You'll Actually Pay
A torsion spring replacement typically costs $250 to $450 installed, depending on the spring size and your door weight. Extension springs run $200 to $350 installed. Labor is usually $100 to $150 per spring. If both springs need replacing (which is smart, not wasteful), expect $400 to $700 total for torsion or $300 to $500 for extension.
This is where calling for an estimate matters. Cheap quotes often hide upsells or use lower-quality springs. Real costs depend on your door's weight, the springs' gauge, and whether you're replacing one or both. Our detailed breakdown helps you understand what you're paying for. We've helped homeowners avoid the $800 "quotes" from big-box companies that inflate prices.
When Should You Replace Springs?
Springs don't always fail suddenly. Watch for a door that opens partially then stops, or one that's harder to open manually. These signs point to a weakening spring. If your door is 7 to 9 years old, both springs are near end-of-life regardless of symptoms. Replacing both at once saves money long-term because you avoid a second service call.

Frequently Asked Questions
Can I replace one garage door spring instead of both? Technically yes, but it's not smart. The second spring is under the same stress and will likely fail soon after. Replacing both at once costs slightly more upfront but saves a second service call and emergency fee down the road.
How long does a spring replacement take? Most spring replacements take 30 to 60 minutes for a professional. If both springs need replacement, plan on 60 to 90 minutes. We offer same-day appointments for urgent repairs across Rhododendron.
Are torsion springs always better than extension springs? Torsion springs are safer and more durable, but extension springs work fine for lighter doors and cost less. The best choice depends on your door's weight, your budget, and your safety priorities. We'll recommend what fits your situation.
What causes garage door springs to fail? Springs fail from normal wear, rust, temperature changes (common in Oregon winters), and repeated opening and closing cycles. A spring lasts roughly 7 to 10 years depending on use and climate conditions.
Can I tell if a spring is about to snap? Sometimes. Listen for creaking or popping sounds. Watch for a door that opens unevenly or feels heavier. These hint at weakening springs. Often, though, failure happens without warning. Regular inspections catch issues early.
