Garage Door Springs in Dundee: Torsion vs. Extension (What You Need to Know)
2026-08-21 7 min read
Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch to do the same job. Your door's design, weight, and balance determine which one you have, and knowing the difference could save you money and prevent injury.
What Are Torsion Springs?
Torsion springs are the safer, more durable choice for most homes. They're mounted horizontally above the door opening and use rotational force to counterbalance the door's weight as it opens and closes. A torsion spring typically lasts 7 to 9 years with normal use. When properly installed, they wear evenly and fail predictably, which is much better than the alternative.
The downside? Replacing a snapped spring requires professional tools and expertise. DIY attempts here are genuinely dangerous. The spring stores enormous tension. A broken torsion spring can't support the door, and the coils can whip violently if mishandled. Dundee homeowners who've tried repairs at home have learned this lesson the hard way.
If you're unsure which type you have, look above your door. A single or double metal rod running parallel to the door frame = torsion. This is the premium setup.
Why Torsion Springs Fail
Rust, lack of lubrication, and daily wear are the main culprits. Humid climates like Dundee and the surrounding central Florida region accelerate rust formation on the metal coils. Every open and close cycle puts stress on the spring. After thousands of cycles, the metal fatigues and snaps.
What Are Extension Springs?
Extension springs hang along each side of your door, one on the left and one on the right. They stretch when the door closes and contract to help pull it open. They're cheaper upfront but don't last as long as torsion springs. Most extension springs fail after 5 to 7 years.
Extension springs also come with safety cables running through their center. If a spring snaps, the cable catches it and prevents it from flying across your garage. This is a key safety feature but not a substitute for professional replacement.

Cost and Replacement Estimates
A single torsion spring replacement typically runs between $200 and $400 for parts and labor. Extension springs cost $150 to $300 per spring. If both extension springs fail at once (which happens often), you're looking at $400 to $600 total. These are ballpark figures. The actual cost depends on your door's weight, the spring's diameter, and labor rates in your area.

When Springs Snap: What to Do
A snapped spring means your door won't open, or it opens and closes unevenly. You'll hear a loud bang or snap. Stop using the door immediately. Continuing to operate it puts extra load on the opener and other parts.
Don't attempt to lift the door manually if a spring is broken. The door is now a several-hundred-pound weight with no counterbalance. This is an emergency garage door service situation. Call a licensed technician right away.
Why DIY Spring Replacement Is Dangerous
Springs hold up to 500 pounds of tension. A snapped torsion spring can launch coils or the center shaft across a garage at lethal speeds. Extension springs can snap like a whip. Even trained technicians use special winding tools and safety procedures.
If you've been thinking about routine garage door maintenance to catch problems early, spring inspection is part of that package. A professional can spot a weakening spring before it fails completely.
Getting Your Springs Inspected in Dundee
Annual maintenance catches worn springs before they break. During a tune-up, a technician applies lubricant, checks the spring tension, and measures wear. For Dundee residents, this usually costs $100 to $150 and can prevent a $400 emergency repair.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs fail sooner, usually after 5 to 7 years. Lifespan depends on how often you use the door, humidity, and maintenance. Regular lubrication extends the life by a year or two.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools, knowledge of proper tension, and safety training. A mistake can cause serious injury or death. Always hire a licensed technician for this work, even if it costs more.
Why did my garage door spring snap without warning? Springs don't always give obvious signs. Rust, accumulated fatigue, and lack of lubrication cause sudden failure. That's why annual inspections matter. A pro can spot a weakening spring months before it snaps.
How much does a snapped spring repair cost near me? In Dundee, expect $200 to $400 for a single torsion spring replacement, or $150 to $300 per extension spring. Emergency service after hours costs more. Call (863) 563-3317 for an exact quote.
Should I replace both springs at the same time? Yes, if you have two extension springs. They wear at the same rate, so the second one will fail soon after the first. Replacing both at once saves you a second service call and the cost of a second emergency visit.
