Garage Door Springs in La Mesa: How They Work and Why They Matter
2026-06-25 7 min read
A snapped garage door spring won't let your door open or close, leaving your car trapped inside or your home exposed. The good news is understanding how these springs work helps you spot problems early and avoid costly emergency repairs.
Your garage door weighs 300 to 500 pounds. Two steel springs balance that weight, making the opener's job simple and keeping the system safe. When springs fail, the door becomes a safety hazard and a genuine inconvenience. Most homeowners in La Mesa don't realize springs need professional attention until something goes wrong.

How Garage Door Springs Actually Work
Two main types of springs do this critical job: torsion springs and extension springs.
Torsion springs sit above your door, running horizontally along a metal shaft. They twist and untwist as the door moves, storing and releasing energy with mechanical precision. When you press the opener button, these springs do roughly 90 percent of the lifting work. The opener just guides the door smoothly along the tracks.

Extension springs hang on either side of the door, running parallel to the upper tracks. They stretch and contract, pulling the door up as it opens. Less common in modern installations, but still found in older La Mesa homes, extension springs require safety cables threaded through them. Without those cables, a snapped extension spring can snap down violently and cause serious injury.
Both types last roughly 7 to 9 years under normal use. That means a spring installed when you moved in might be near the end of its life right now.
Why Springs Fail
Springs fail from metal fatigue, not sudden shock. Every open and close cycle stresses the coils slightly. After 10,000 to 15,000 cycles (about 7 to 9 years), the metal simply breaks. A snapped spring makes a loud bang that sounds like a gunshot in your garage. Don't ignore that sound or try to force the door open manually.
Temperature swings in San Diego County also accelerate wear. Heat causes metal to expand and contract, weakening the material over time. If you haven't had your springs inspected recently, now is the right moment to do so.

Never attempt spring replacement yourself. Springs are under extreme tension. A slip or mistake can cause serious injury or death. Even experienced DIYers get hurt working on springs. This is one repair where calling a professional isn't optional, it's essential.
A trained technician will assess which spring type you have, measure the exact specifications, and install matched replacements. They'll also inspect the door balance and test the system before leaving.

Frequently Asked Questions
How do I know if my garage door spring is broken? The door won't open or close smoothly, you hear a loud bang from the garage, or the door feels heavy and unbalanced. Never force a stuck door. Call a professional immediately.
Can I drive under a garage door with a broken spring? No. A broken spring means the door could fall without warning. Stay away from the door opening until a technician inspects it.
How much does it cost to replace garage door springs? Torsion spring replacement typically costs $200 to $400 depending on door size and spring type. Extension springs cost slightly less. Labor and parts are included in most quotes.
How long do garage door springs last? Quality springs last 7 to 9 years with normal use, which means roughly 10,000 to 15,000 open and close cycles.
Should I replace both springs at once? Yes. If one spring snaps, the other is likely near failure. Replacing both springs together prevents a second breakdown weeks later and saves on labor costs.
