Garage Door Springs in Union: Torsion vs. Extension (Which Do You Have?)
2026-08-11 7 min read
If you've ever stared at your garage door stuck halfway up, frustrated and unsure what went wrong, you likely have a spring problem. But here's what most homeowners don't realize: the type of spring your door uses determines everything about repair cost, safety risk, and urgency. Understanding whether you have a torsion spring or extension spring isn't just technical trivia. It could save you from a dangerous DIY mistake.
Torsion Springs vs. Extension Springs: The Key Differences
Torsion springs and extension springs do the same job: counterbalance your garage door's weight. But they work completely differently. See our guide on belt replacement: a complete guide for homeowners.
Torsion springs wind up like a clock spring. They sit horizontally above your garage door opening, held by a steel shaft. When the door closes, the springs tighten. When it opens, they unwind and release energy. Most residential doors built after 1980 use torsion springs because they're more durable and safer. They last 7 to 9 years with normal use.
Extension springs hang vertically on both sides of your garage door track. They stretch as the door closes and contract as it opens. Older homes, especially in the Union area, still use these. They're cheaper upfront but require safety cables to catch them if they snap. Extension springs also fail more frequently than torsion springs. Read about garage door springs in union: when to replace & what it costs.
The practical difference matters: a snapped extension spring is often visible (the cable hangs loose). A broken torsion spring is harder to spot. You'll notice the door won't open manually, or the opener struggles to lift it.
Why Spring Type Affects Your Safety and Repair Cost
This is where my experience in the field gets real. I've responded to emergency calls where homeowners tried replacing extension springs without proper tools or knowledge. The spring can snap back and cause serious injury. Torsion springs are even more dangerous because the tension is immense. Even at rest, they store enough energy to cause fractures or worse.
When you call Garage Door Union or any spring specialist near you, the first question we ask is: which type do you have? That determines whether we need special tools, how long the repair takes, and what the estimate will be. Extension springs typically cost less to replace than torsion springs, but both require professional installation.

How to Identify Your Spring Type
Stand outside your garage and look above the door opening. If you see a horizontal spring wound around a shaft with cone-shaped pulleys on each end, you have a torsion spring. If you see vertical springs hanging alongside the door tracks with cables running through them, you have extension springs.
Don't touch them. Even looking at a broken or stressed spring can be deceptive. Springs fail without warning. What looks fine can fail the moment someone tries to open the door.
If you're unsure or can't see clearly, take a photo and text it to us. We can often identify your spring type remotely and give you a ballpark cost estimate before we arrive. We offer same-day estimates for garage door springs in Union) so you're never left guessing.
When to Replace Springs vs. Repair Them
Springs don't get "repaired" in the traditional sense. They're replaced. When a torsion or extension spring fails, it's done. The only safe option is full replacement.
However, if only one spring is broken and your door uses two springs (common for heavier doors), you should replace both at the same time. Replacing one creates an imbalance. The new spring will wear faster, and your door can malfunction unpredictably. A professional can assess this during an initial inspection.
Age also matters. If your springs are nearing the 7 to 9 year mark, even if one hasn't failed yet, consider replacing both proactively. This prevents a second failure weeks later and saves on repeat service calls.

Why DIY Spring Replacement Is a False Economy
The cost difference between DIY and professional installation is smaller than you'd think. Spring replacement requires a spring compressor tool (which few homeowners own), precise tensioning knowledge, and understanding of safety cable installation. Plus, if something goes wrong, you're liable.
Insurance typically doesn't cover injuries from DIY garage door work. Professional installation includes warranty protection and liability coverage. When a snapped spring nearly takes out your hand or your car, professional service looks like the best money you ever spent.

Frequently Asked Questions
Can I open my garage door manually if the spring is broken? No. A broken spring removes the counterbalance mechanism. The door becomes extremely heavy and dangerous to lift manually. Attempting it can cause injury. Leave it closed and call a professional.
How long does spring replacement usually take? Most spring replacements take 1 to 2 hours, depending on your spring type and door condition. Same-day service is typically available in Union if you call before noon.
What's the average cost to replace garage door springs? Extension spring replacement ranges from $150 to $300. Torsion spring replacement is typically $250 to $400. Prices vary based on spring size, door weight, and local labor rates. We provide detailed estimates before work begins.
Do both springs need to be replaced at the same time? If you have two springs and only one is broken, yes. Replacing just one causes imbalance and premature failure of the new spring. Professional replacement means both springs are tensioned equally.
How often should garage door springs be replaced? Springs typically last 7 to 9 years with normal use. Heavy daily use shortens this timeline. Preventive replacement at the 7 year mark can prevent emergency failures.
