Garage Door Springs in Dennison: Torsion vs. Extension (and When They Fail)
2026-08-10 5 min read
You've got two types of garage door springs, and they work completely differently. Torsion springs twist above your door; extension springs pull from the sides. When one snaps, your door won't budge, and you'll need professional help fast. I've been waking up to snapped spring calls for 15 years, and this is the one repair that cannot wait.
What Actually Happens Inside Your Springs
Garage door springs are under brutal tension. A 200-pound door gets lifted by springs carrying roughly 150 pounds of force each. Torsion springs handle that by rotating on a metal rod. Extension springs stretch and contract like giant rubber bands on a pulley system.
Both types last 7 to 9 years on average if your door operates roughly 4 to 8 times daily. After that, metal fatigues. A spring doesn't just wear slowly, either. It fails suddenly. One day it's fine. The next morning, it snaps.
When a torsion spring breaks, you hear a loud bang. That's the rod spinning freely because the spring lost all tension. When an extension spring snaps, the door crashes down or gets stuck halfway. Neither scenario is safe.
Torsion vs. Extension: Which Do You Have?
Open your garage and look up. If you see a horizontal metal rod running above the door with wound-up springs on it, you have torsion springs. If you see springs stretched along the top sides of the door opening, connected to pulleys, those are extension springs.
Most homes in Dennison and surrounding areas use torsion because they're smoother and safer. Extension springs are cheaper upfront but wear faster and pose more injury risk if they snap while you're near them. That's why I always recommend torsion to my customers if they're replacing both springs.
The difference matters for cost. A torsion spring replacement runs $200 to $400 per spring, including labor. Extension springs cost $150 to $250 per spring. But torsion lasts longer, so you're not replacing them as often.

Why Your Estimate Matters More Than You Think
When you call a garage door company near me and ask for an estimate, they should tell you which springs you have, their age, and whether you need one or both replaced. Some shops will push you to replace both even if only one broke. That's sales, not service.
Here's the truth: if one spring snaps and the other is less than 5 years old, you can often replace just the broken one. But if both are older than 8 years, I'll recommend replacing both at the same time. Springs are a matched pair, and an old spring plus a new spring will wear unevenly.
A proper estimate also accounts for your door's weight. Heavier doors need stronger springs. Some doors use two torsion springs; others use four. The labor involved differs too. Our team at Dennison Garage Doors always inspects the entire system before quoting because a snapped spring can damage the cable or rod.
Same-Day Service Isn't a Luxury, It's a Necessity
A broken spring means your door is immobile. You can't get your car out. You can't secure your garage. If you work from home, that's annoying. If you run a business, that's a revenue hit.
That's why we prioritize spring calls. Most spring failures happen early morning when you're trying to leave. We aim to be at your door within hours, not days. We carry springs in our trucks for common door weights and styles, so we can usually finish the job same day.
Emergency pricing is different from standard pricing. If you need us at 6 a.m. on a Sunday, that costs more than scheduling a Tuesday morning appointment. But you're paying for speed and availability, which has real value when your door won't work.

Preventing Spring Failure (Sort Of)
You can't stop springs from aging. Metal fatigue is physics. But you can slow it down with regular garage door maintenance in Dennison to keep everything running smoothly. That means lubricating the springs every six months with a silicone spray, checking the cables for fraying, and ensuring the door balances properly.
A balanced door doesn't work your springs as hard. If your door is lopsided or doesn't open smoothly, that's stress on the springs. We can adjust that for you when we're out for any other service.
Don't try to oil or adjust springs yourself. If a spring is under tension and fails while you're working on it, you could be seriously hurt. This is 100 percent a job for a professional.

Frequently Asked Questions
How long do garage door springs actually last? Torsion and extension springs typically last 7 to 9 years with normal use (4 to 8 cycles daily). Factors like humidity, temperature swings, and door weight affect lifespan. Springs in Dennison's winter climate sometimes fatigue faster due to metal contraction.
Can I replace just one spring, or do I need both? If one spring snapped and the other is less than 5 years old, you may replace just the broken one. However, if both are older than 8 years, replacing both prevents uneven wear and future calls. We assess the condition during your estimate.
What's the difference between torsion and extension spring cost? Torsion springs cost $200 to $400 per spring installed; extension springs cost $150 to $250. Torsion lasts longer, so the higher upfront cost often saves money over time despite fewer replacements needed.
How fast can you service a snapped spring in Dennison? We aim for same-day service on spring breaks. Call (740) 519-8454 early, and we'll get you back on the road. Emergency calls outside business hours carry a premium fee, but your door gets fixed quickly.
Is it safe to drive under a garage door with a broken spring? No. Never force a door open or closed if a spring is broken. Your door could fall unexpectedly. Contact a professional immediately. A broken spring means the door is not balanced and poses a safety hazard.
