In our Experienced Local Team Azusa, we've seen this problem again and again: homeowners don't know which type of garage door springs they have, so they can't describe the issue when they call for help. Torsion and extension springs work differently, fail differently, and cost differently to replace. Knowing yours saves time and money.
Torsion springs sit above your garage door opening, mounted on a metal shaft. They twist and untwist to lift the door's weight. One torsion spring can handle a single-car door. Two springs handle double-car doors. When a torsion spring snaps, the door won't open at all. You'll hear a loud bang.
These springs are harder to spot visually because they're tucked above the door frame. But if you look straight up when the door is closed, you'll see the shaft with one or two coiled springs wrapped around it. Torsion springs last 7 to 9 years with normal use.
Why do we recommend torsion? They're smoother, quieter, and safer than their counterparts. They also protect your garage door opener from strain. If a torsion spring fails suddenly, the door doesn't crash down because the spring mechanics distribute load evenly.
Extension springs run along both sides of your door, above the horizontal tracks. They stretch and contract to counterbalance the door's weight. When one snaps, you might still open the door manually, but it'll be uneven and jerky.
Extension springs are easier to spot. Look at the sides of your garage door opening. You'll see a spring running parallel to the track, usually with a cable running through it. That cable is critical. If an extension spring breaks and the cable isn't there, the spring can whip dangerously across your garage.
Extension springs typically last 5 to 7 years. They're less expensive upfront than torsion springs, but they wear faster and need cable replacements more often.
Southern California heat accelerates spring wear. Azusa summers get hot, and that thermal cycling stresses metal. Springs in our area often fail sooner than the manufacturer's timeline suggests. We've pulled countless snapped springs during August and September when homeowners finally call because they're locked out of their garage.

A snapped spring is obvious: you hear the bang, and the door won't budge. But springs often show warning signs before they break completely. Listen for squeaking or creaking when the door operates. Watch for jerky movement or the door sagging on one side. These are hints that a spring is losing tension.
If you notice these signs, don't wait. A failing spring puts extra load on your garage door opener and can damage the door itself. We've replaced many openers that could've been saved if the homeowner had addressed the spring first.

Extension spring repair usually means replacing the cable and maybe one spring. That's cheaper. Torsion spring repair almost always means replacing both springs as a pair, even if only one snapped. Why? Springs wear at the same rate. If one fails, the other is close behind.

Spring problems don't fix themselves, and they get worse fast. The sooner you act, the less secondary damage you'll face.
Can I replace just one spring instead of both? For torsion springs, no. Both springs wear together, so replacing one leaves the other ready to fail within weeks. For extension springs, you can replace just one, but we recommend both for balance and longevity.
How long does a spring replacement take? About one hour for torsion springs. Extension springs take 45 minutes. We'll have your door operational the same day.
Why are torsion springs more expensive? They're heavier-duty and safer. Torsion springs also require precision installation and special tools, which adds labor cost. But they outlast extension springs and protect your opener.
Is a snapped spring a safety emergency? Yes. A broken extension spring can whip around. A broken torsion spring leaves the door unsupported. Both need immediate professional attention. Don't DIY this repair.
Do springs need maintenance? Regular lubrication and visual inspections help springs last longer. Include spring checks in your annual garage door tune-up.
