A snapped spring won't let your garage door open or close, no matter how hard your opener works. The good news: understanding which type of spring you have and recognizing early warning signs can save you hundreds of dollars and hours of frustration. Most Coronado homes rely on one of two spring systems, and knowing the difference matters when you need a repair fast.
Your garage door uses either a torsion spring or extension springs. These aren't interchangeable, and the type determines how your door moves and how much replacement will cost.
Torsion springs sit above the garage door opening, mounted on a horizontal shaft. They twist (or "torque") to lift the door, storing enormous energy in a tightly wound coil. One torsion spring typically handles doors up to 12 feet wide. Heavier or wider doors need two springs working in tandem. Extension springs run along the upper sides of your door frame, stretching and contracting as the door moves up and down. They're common in older homes and smaller garage doors.
The key difference: torsion springs are more durable, more efficient, and last longer (typically 7 to 9 years with normal use). Extension springs wear out faster because they experience more friction and stress during every cycle. Neither type lasts forever, but torsion systems are what most modern Coronado homes have installed.
Garage door springs break under tension. Every time your door opens or closes, the spring works. A typical spring handles 10,000 to 15,000 cycles before fatigue sets in. That sounds like a lot until you realize one cycle per day means your spring lasts 27 to 41 years. But most doors cycle multiple times daily, and salt air near the coast accelerates corrosion and wear.
Torsion springs fail when the metal loses its ability to hold tension. You'll hear a loud bang or snap. After that, your door won't budge. Extension springs can snap too, but they often just lose tension gradually, making your door feel heavier and heavier. If you notice your door sagging slightly or struggling to open all the way, a weakened extension spring is likely the culprit.

Spring replacement cost varies based on type, quantity, and whether your door is standard or oversized. A single torsion spring replacement typically runs between $200 and $400 in Coronado. Two torsion springs (common for heavier doors) cost $350 to $600. Extension spring replacement is usually cheaper, around $150 to $300 per spring, but you often need two.
Labor adds another $100 to $200 depending on difficulty. If your springs have been failing for months and rust has built up on the shaft, removal takes longer. Emergency same-day service carries a premium, but when you can't access your garage, the cost is worth the peace of mind.

Garage door springs store enough energy to cause serious injury or death. A snapped spring under tension can snap back with force equivalent to a loaded crossbow. Even experienced mechanics respect this danger. The shaft, brackets, and cables are all under extreme stress. One wrong move during removal or installation can injure your hands or face.

How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use. Extension springs wear faster, often 5 to 7 years. Lifespan depends on cycle frequency and maintenance. Salt air in coastal areas like Coronado can shorten this window due to corrosion.
Can I replace just one spring if I have two? No. If one spring fails, the other is close behind. Replacing both at the same time ensures balanced door movement and prevents a second failure within weeks. It's more economical than paying for two service calls.
What's the difference between a torsion and extension spring? Torsion springs twist to lift the door and are mounted horizontally above the opening. Extension springs stretch along the sides of the frame. Torsion springs are more efficient, last longer, and are standard in modern homes.
How much does spring replacement cost in Coronado? A single torsion spring costs $200 to $400 plus labor. Two springs run $350 to $600. Extension springs are cheaper but often need replacing in pairs. Same-day service may add a fee depending on timing.
Is a snapped garage door spring an emergency? Yes. Your door won't open or close without the spring. You can't safely use the opener, and the door is a security risk. Call for immediate service rather than waiting or attempting a DIY fix.
