After 15 years turning wrenches on garage doors across El Cajon and San Diego County, I can tell you this: most homeowners don't understand their garage door springs until one snaps. Then panic sets in. Let me cut through the confusion and explain what you're actually dealing with, why they fail, and what a replacement really costs in our area.
Your garage door weighs 300 to 500 pounds. You don't lift that with your arms. Springs do the heavy lifting. They store energy when the door closes and release it when you open. Without them, your opener would burn out in months, or the door would crash down. Springs are the unsung heroes of your entire system.
There are two main types in residential garages: torsion springs and extension springs. Torsion springs sit above the door on a horizontal rod and twist to lift the weight. Extension springs hang on each side and stretch like rubber bands. Most modern homes in El Cajon use torsion springs because they're more durable and safer. Either way, they wear out. Springs typically last 7 to 9 years with normal use, sometimes longer if you baby your door.
Torsion springs are the premium option. They balance the load evenly and fail more predictably. When one breaks, you usually get a loud bang but a relatively safe situation. They're also harder to install, which is why DIY isn't smart here. One mistake with a torsion spring under tension can cause serious injury.
Extension springs are cheaper upfront but less forgiving. They hang alongside the tracks and work in pairs. If one snaps, the other side still pulls, and your door can bind or tilt. Both types have a lifespan measured in cycles. A cycle is one open and one close. A garage door that cycles 3 to 5 times daily will need spring replacement sooner than a door cycled once a day.

A snapped spring usually announces itself loudly. You'll hear a sharp crack or twang, and the door won't open. But you don't have to wait for that. Watch for these red flags: the door feels heavier than normal when you open it manually, it sags on one side, or the opener struggles more than it used to. Sometimes you'll see the spring visibly broken or notice a gap in the coil. If you spot any of these, call us. Driving on a broken spring is possible but hard on your opener and dangerous.
I've seen plenty of homeowners try to work around a failing spring by forcing the opener to do more. That's how you end up with a $600 opener replacement instead of a $200 spring. We've written a detailed guide on complete garage door spring replacement that covers the full process and why professional installation matters.
Spring replacement isn't cheap, but it's not outrageous either. A single torsion spring costs between $150 and $300 installed, depending on the size and quality. Extension springs run $100 to $200 per pair. Labor adds another $100 to $150. So a typical torsion spring job lands around $250 to $450 total. Some homeowners replace both springs even if only one breaks. That's smart thinking. The second one isn't far behind, and you avoid a second service call in six months.

I'm going to be direct: don't replace springs yourself. This isn't like changing oil. Springs are under extreme tension. A slip, a wrong move, or a misunderstanding of the mechanism can cause the spring to snap and send metal flying at your face or hands. I've treated neighbors who tried it. It's not worth it. Our technicians have the right tools, the experience, and the insurance to handle it safely. We can usually get to your El Cajon home within hours if you call early in the day.
If your door is stuck or you heard a snap, don't keep forcing the opener. Turn it off and call us. If the door is up, leave it up. If it's down, leave it down. We'll handle the rest.
For routine maintenance to extend spring life, check our maintenance checklist and review our safety guide so you know what to watch for between service calls.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years under normal use (3 to 5 cycles per day). Lifespan depends on cycles and maintenance. Regular lubrication and inspection extend life.
Can I replace one spring or should I replace both? If one torsion spring breaks, we recommend replacing both. The second is likely near failure. This prevents a second breakdown weeks later. Cost difference is minimal compared to two service calls.
How much does spring replacement cost in El Cajon? Torsion spring replacement runs $250 to $450 installed. Extension springs cost $200 to $350 per pair. Prices depend on spring size, door weight, and any opener adjustments needed.
Is it safe to use my garage door with a broken spring? No. A broken spring puts all weight on the opener, which will burn out quickly. You risk the door crashing down or getting stuck. Call for repair immediately.
What's the difference between torsion and extension springs? Torsion springs twist above the door and handle load evenly. Extension springs stretch on both sides. Torsion is safer and lasts longer but costs more. Extension springs are cheaper but less reliable.
