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 job. Most homes in Mount Dora use torsion springs because they're safer and last longer. If your door won't open or you hear a loud bang, a snapped spring is usually the culprit.
I've responded to countless emergency calls where homeowners were shocked their springs broke. The truth is less mysterious than you think. Garage door springs typically last 7 to 9 years with regular use. They cycle open and close thousands of times. Metal fatigues. It's physics, not a design flaw. See our guide on brand comparison: what every homeowner should know.
Heat and humidity accelerate that wear. Mount Dora's warm, humid climate doesn't help. Springs corrode slightly faster here than in drier regions. Lack of maintenance speeds failure too. If your door isn't lubricated or balanced properly, springs work harder than they should.
A snapped spring usually announces itself loudly. You'll hear a crack or bang from the garage. Your door becomes impossible to open, even with the opener. Never force it. A broken spring means the full weight of your door (typically 300 to 500 pounds) falls entirely on the opener motor and cables. That's a recipe for expensive secondary damage.

Torsion springs wind up tension like a clock spring. When you open the door, they gradually release that stored energy. They're positioned horizontally above the door opening, usually one or two depending on door size. A single snapped torsion spring can disable your entire system immediately.
Extension springs work opposite. They stretch as the door closes, then contract to lift it. You'll find them on either side of the door. If one breaks, sometimes the other can still support the door temporarily. But that's temporary. Using an extension spring system with one broken spring will snap the remaining spring within days.
Torsion springs are generally safer because they're under constant, controlled tension. Extension springs can snap violently and whip around dangerously. I've seen extension spring failures injure people standing nearby. Torsion designs minimize that risk.

Spring replacement cost varies. A single torsion spring typically runs $150 to $300 installed. Two springs cost $250 to $500. Extension springs are usually less expensive per spring but labor is similar.
The good news: spring replacement is straightforward. A qualified technician can handle it in under an hour. The bad news: you can't ignore it. Driving on a snapped spring accelerates other failures. Your cables, drums, and pulleys all wear faster.
When you call for an estimate, be ready to describe what happened. Did you hear a bang? Can you open the door at all? Does it feel heavier than normal? These details help us diagnose the exact problem and give you an accurate cost quote. We also offer pricing for preventive spring replacement if both springs are aging. Replacing them together costs less than emergency repairs six months apart.

Most homeowners wait for a spring to fail. Smart ones don't. Regular maintenance catches worn springs before they snap. We inspect spring tension, lubricate them annually, and check cable condition. A garage door tune-up and maintenance appointment catches these issues early.
Springs under-tensioned force your opener to work harder, burning out the motor faster. Over-tensioned springs snap suddenly. A professional balances everything so your door opens and closes smoothly with minimal opener strain.
Also, don't ignore weather. Mount Dora gets intense summer heat and occasional cold snaps. Temperature swings affect metal expansion. Springs that were fine in winter might fail in July. Seasonal inspection catches this.
If your door won't open and you suspect a snapped spring, stop. Don't try to force it with the opener. Call us for a same-day estimate. Schedule your free assessment here or dial (352) 758-7386.
Spring failure is urgent but fixable. We'll diagnose whether it's torsion, extension, or something else. Most spring jobs are completed the same day you call. That means your door works again and your family is safe.

How do I know if my spring is broken? You'll hear a loud bang or crack. Your door becomes very heavy or won't open at all. The opener may hum but nothing moves. These are clear signs of spring failure. Never force the door.
Can I replace a garage door spring myself? Springs are under extreme tension. DIY replacement risks serious injury or death. Always hire a licensed professional. The cost difference isn't worth your safety.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 10,000 cycles). Extension springs last slightly less. Climate and maintenance affect lifespan. Florida heat shortens the timeline.
Why are my springs rusting? Mount Dora's humidity and salt air corrode metal. Rust weakens springs and accelerates failure. Regular lubrication and protective coatings help. Annual maintenance catches rust early.
Should I replace both springs at once? Yes, if both are similar age. Replacing one leaves the other to fail soon after. Doing both together saves on labor and prevents another emergency next season.
