Garage door springs are the hardest working component in your entire door system, yet most homeowners never think about them until one snaps. We've responded to countless emergency calls in Coronado where a snapped spring has left a family trapped with a 400-pound door that won't budge. Let's cut through the confusion about garage door springs so you can understand what's happening in your garage and when to call for help.
Your garage door springs don't last forever. A typical spring lives 7 to 9 years, depending on use frequency and local climate. Here in Coronado, our salty air and temperature swings put extra stress on metal components. Springs fail because they're under constant tension. Every time your door opens and closes, the spring loses a tiny bit of its elasticity. After thousands of cycles, that metal fatigues and eventually breaks. See our guide on smart garage door technology in coronado: what you need to know.
The scary part? A snapped spring can happen without warning. You'll hear a loud crack or bang from the garage, and suddenly your door becomes a dead weight. Don't try to force it open manually. A 400-pound door falling without spring tension can cause serious injury.
These two types do the same job but work differently, and knowing which you have matters for repair cost and safety. Read about garage door cost & pricing in coronado: what homeowners really pay.
Torsion springs mount horizontally above your door opening. They twist (torque) to lift the door. Most modern homes have torsion springs because they're smoother, quieter, and more reliable. If one snaps, the door still won't open, but at least the broken spring is contained above the opening where it can't whip around.
Extension springs hang vertically on both sides of the door. They stretch as the door lowers and contract as it rises. Older homes in Coronado often have these. When an extension spring breaks, it can snap violently and damage the cable or track. They're also noisier during operation.
Which do you have? Look above your door opening. If you see a tightly coiled spring running left to right, you have torsion. If you see springs on the left and right sides that look like they're being pulled, those are extension springs.

A spring replacement isn't cheap. An estimate for a single torsion spring repair typically runs $200 to $400, depending on spring size and door weight. If both springs need replacement (which we often recommend for balance), expect $400 to $800 total. Extension springs are usually less expensive per unit but can still total $300 to $600 for a pair.
The cost depends on several factors. Your door's weight, the spring's load rating, and whether you need labor for same-day service all play a role. We always provide a free estimate before starting work. Never let a door sit with a broken spring. Every day you leave it unrepaired, you risk cable damage or worse.

You can't stop springs from aging, but you can extend their life. Regular lubrication with a silicone-based spray keeps springs moving smoothly and reduces friction. Once a year, apply a light coat to the entire spring assembly (avoid the door panels).
Also check your door's balance quarterly. Open the garage door halfway and release it. If it falls or rises, the springs are losing tension. Don't ignore this. Imbalanced doors wear out springs faster and put strain on your opener.
Coronado's coastal salt air corrodes metal faster than inland areas. Consider scheduling spring maintenance annually rather than waiting for failure. Our garage door maintenance guide covers seasonal checks that catch problems early.
Here's the hard truth: do not attempt to replace garage door springs yourself. Springs are under 200+ pounds of tension. If a tool slips or you misalign the coils, the spring can snap and cause serious injury. We've seen broken bones, lacerations, and worse from DIY attempts.
This is one of those repairs where professional help isn't optional. Garage Door Coronado technicians have the proper tools, safety equipment, and experience to replace springs without risk. We also inspect cables, tracks, and rollers while we're there to catch other problems before they become emergencies.
If your door is stuck and won't open, contact us for same-day emergency service.
How do I know if my spring is about to break? Listen for creaking or popping sounds during operation. If the door feels heavier than normal or moves slowly, the spring is losing tension. Visible gaps or rust on the spring coils are also red flags. Don't wait for a complete failure.
Can I use just one spring if the other breaks? Technically yes, but we don't recommend it. Mismatched springs create an imbalanced door that wears the opener faster and risks uneven movement. Replace both springs at the same time for safety and longevity.
How long does a spring replacement take? Typically 1 to 2 hours from start to finish. We'll inspect the entire system while we're here. Same-day service is available for most calls in Coronado.
Do extension springs need different maintenance than torsion? Both need annual lubrication and seasonal balance checks. Extension springs should also be inspected for cable wear since they're more exposed. Ask your technician for a full inspection report.
What happens if a spring breaks while the door is open? The door will stay where it is since there's no spring tension to hold it. Close the garage by hand carefully (it will be heavy), then call for repair. Never operate the opener with a broken spring.
