Garage door springs in Casselberry 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. Both fail eventually, and when they do, your door won't open. Knowing which one you have helps you understand repair costs and safety risks.
I've responded to hundreds of spring emergencies across Central Florida. The worst calls come from homeowners who try DIY fixes or ignore warning signs. A snapped spring can turn a simple repair into an injury. Let's cut through the confusion so you stay safe and informed. See our guide on garage door safety features in casselberry: auto-reverse & photo eye explained.
Torsion springs do most of the work in modern garage doors. They're mounted horizontally above the door opening and wind up like a clock spring. As your door closes, tension builds. When you open it, that stored energy releases and lifts the entire weight.
Here's what matters: a single torsion spring typically lasts 7 to 9 years with normal use. Casselberry's heat and humidity accelerate wear. I've seen springs fail at year five in homes where the garage faces west and bakes in afternoon sun. The metal fatigues faster in our Florida climate.

When a torsion spring snaps, you'll hear a loud bang. Your door becomes a dead weight. The opener can't budge it. Worse, if you ignore it and keep forcing the opener, you risk burning out the motor or having the door fall on a person or vehicle.
Torsion spring replacement costs between $200 and $400 per spring, including labor. Most doors need one or two. That's far cheaper than a new opener or medical bills.
Extension springs hang along the sides of your door frame. They stretch as the door opens and contract as it closes. Older doors and lighter single-car doors often use these instead of torsion springs.
Extension springs fail the same way torsion springs do, but the failure mode is different. Instead of one loud snap, you might notice your door opening unevenly or feeling heavier on one side. If one extension spring breaks and the other holds, the door tilts. That imbalance strains the opener and tracks.
Safety cables run through extension springs for good reason. When an extension spring snaps, that cable catches it and prevents the spring from whipping across the garage like a metal whip. Without the cable, a snapped spring can cause serious injury.
Check your extension springs monthly. Look for rust, fraying cables, or visible gaps between coils. If you spot damage, schedule a free quote with our team before the spring fully fails.
Our location near Orlando means year-round heat and afternoon thunderstorms. Salt from nearby coastal areas can travel inland and corrode metal. Dust from construction also settles on garage doors.
Repeated opening and closing wears springs down. A typical garage door cycles 3 to 5 times daily. Over 7 to 9 years, that's thousands of cycles. The metal fatigues.
Humidity causes rust from the inside out. Even painted springs can develop internal corrosion. Once rust starts, the spring weakens and fails faster.

A single snapped spring always needs replacement. You can't weld or patch a torsion or extension spring safely. The repair would fail under load, and the door could crash down unexpectedly.
If your door is older than 10 years and one spring fails, consider replacing both. Springs of the same age are likely to fail within months of each other. Replacing both at once saves labor costs and prevents a second emergency call.
Minor maintenance like lubrication can extend spring life. Regular inspections catch rust and wear before catastrophic failure. Our maintenance guide covers what to check each month.
Spring replacement cost depends on spring type, door weight, and whether one or both springs need work. A standard torsion spring replacement runs $250 to $350. Extension springs cost $150 to $250 each.
Never attempt to replace springs yourself. The tension in a loaded spring can cause serious injury. Even experienced DIYers have lost fingers and hands. Professional technicians have the right tools and training.

Don't wait for a spring to snap. If your door sounds different, moves slowly, or feels heavier than usual, springs may be wearing out. Early detection saves money and keeps your family safe.
How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs may last 5 to 7 years. Casselberry's heat and humidity can reduce lifespan by 1 to 2 years. Regular lubrication and inspections help springs reach their full lifespan.
Can I open my garage door if the spring is broken? No. A broken spring removes lifting power, and the door becomes extremely heavy. Forcing it open risks damaging the opener, tracks, or panels. Call a professional for safe removal and replacement.
How much does it cost to replace a garage door spring? A single torsion spring costs $200 to $400 installed. Extension springs run $150 to $250 each. If both springs need replacement, expect $400 to $700 total. Get a free estimate before committing.
Are extension springs safer than torsion springs? Both types are equally dangerous when they fail. Extension springs have safety cables to prevent whipping. Torsion springs are more common in modern doors. Safety depends on proper installation and maintenance, not type.
What's the difference between a snapped spring and a stretched spring? A snapped spring breaks completely and stops working instantly. A stretched spring loses tension gradually, making the door harder to open. Both need professional replacement. Stretched springs often precede sudden snapping by weeks.
