Garage door springs are the hardworking heroes behind every smooth open and close. Two main types exist: torsion springs mounted above the door, and extension springs on the sides. A snapped spring won't let your door move safely, so knowing the difference helps you act fast when trouble hits.
I've responded to dozens of emergency calls in Lawndale where a homeowner heard a loud bang, then found their door stuck. That sound? Almost always a spring that finally gave out. Understanding what happened, and what it'll cost to fix, removes panic from the equation.
Torsion springs wind tightly around a metal rod above your garage door opening. They store energy as they twist, then release it to lift the door's weight. Most modern homes use torsion springs because they're durable, balanced, and safer than the alternative.
Extension springs sit horizontally along each side of the door, above the upper tracks. They stretch and contract to help lift the door. Older homes, particularly in coastal areas like Lawndale and nearby Long Beach, often have extension springs. They work fine, but they require safety cables strung through them. Without those cables, a snapped extension spring can whip across your garage like a bullwhip.
This is where my "safety-first" mindset kicks in. I've seen extension springs fail and nearly hit someone standing nearby. That's why torsion springs are preferred now. If you have extension springs, make sure those safety cables are in place.
Garage door springs last roughly 7 to 9 years with normal use (about 10,000 cycles). That's roughly one open and close per day. Hard water, salty air near the coast, and humidity all speed up rust and metal fatigue. Lawndale's marine layer and occasional salt spray accelerate corrosion faster than inland areas.
A snapped spring usually happens without warning. Sometimes you'll notice the door feeling heavier or hear a slight creak weeks before it fails. Other times, one morning you press the opener and nothing moves. The spring finally couldn't hold the tension anymore.
Never try to force a broken spring open manually. The door weighs 300 to 500 pounds. Without a functioning spring, you risk crushing your fingers or worse. This is covered in our garage door safety guide for families, which goes deeper into what not to do.
A single torsion spring replacement typically costs between $150 and $300, plus labor. Extension springs run $100 to $150 per spring. If both torsion springs need replacing (they usually do, since they age together), expect $300 to $600 for parts and professional installation.
Labor takes 1 to 2 hours. Garage Door Lawndale offers same-day service for spring replacements, which matters when your door is stuck and you have places to be. Getting a free estimate helps you understand the exact cost before work begins.

If one spring snaps, both are likely near the end of their life. Replacing both at once prevents a second failure months later, which saves money and hassle in the long run. A technician will inspect the springs, cables, pulleys, and hardware during the visit.
Sometimes springs aren't fully broken, but they're weakening. You might notice the door rising unevenly or the opener working harder than usual. These are warning signs to call for an inspection. Our post on 5 warning signs your garage door spring needs replacement walks through each symptom so you know what to watch for.
Don't ignore a sagging door. Continuing to use it stresses other parts like the opener motor, rollers, and tracks. A small spring issue today becomes an expensive repair tomorrow.

How long do garage door springs typically last? Most torsion and extension springs last 7 to 9 years with regular use. Coastal humidity, salt air, and hard water in Lawndale can shorten lifespan. Professional maintenance helps extend their life.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury if mishandled. Always hire a licensed technician. DIY attempts have resulted in hospitalizations from spring recoil and falling doors.
What's the difference between torsion and extension springs? Torsion springs twist above the door opening; extension springs stretch along the sides. Torsion springs are safer and more reliable. Extension springs require safety cables to prevent dangerous whipping if they break.
How much does a garage door spring replacement cost? Single spring replacement runs $150 to $300 plus labor. Dual springs cost $300 to $600 total. Exact pricing depends on spring size, type, and whether cables or hardware need replacement. We provide free estimates.
Should I replace both springs at once? Yes. If one fails, the other is near failure. Replacing both prevents a second breakdown and ensures balanced door operation. It's more cost effective than replacing springs separately.
