A garage door spring does the heavy lifting, literally. Torsion springs mounted above the door (or extension springs along the tracks on older setups) store the tension that counterbalances a 150 to 250 pound door, so the opener only has to guide it. When a spring snaps, that counterbalance disappears and the full weight lands on the opener, the cables, and you.
Warning: a wound torsion spring holds enough force to cause serious injury if it's handled wrong. This guide covers the warning signs, why replacement needs a trained technician, and what the service visit involves. It will not teach you to wind a spring yourself, because that job should never be a DIY project.
Signs your garage door spring is broken
A broken torsion spring usually announces itself with a loud bang from the garage, followed by a door that barely lifts by hand. You may also see a visible gap in the coil above the door, hear popping or grinding, or notice the door sitting crooked.
- A loud bang from the garage, like a firecracker going off, followed by a door that won't open.
- A visible gap of an inch or more in the torsion spring coil above the door.
- The door feels extremely heavy when you try to lift it by hand.
- Popping, snapping, or grinding noises when the opener tries to move the door.
- The door rises crooked, stops partway, or won't close fully.
- The opener strains, hums, and then gives up.
Why torsion spring replacement is never a DIY job
Torsion springs store enough tension to lift a 200-pound door, and releasing that tension the wrong way can cause serious injury. The job needs specialized winding bars, an exact spring size matched to your door's weight, and experience that only comes from doing it hundreds of times.
The winding bars matter. They are the only safe way to control the spring's tension, and a screwdriver or improvised bar can slip and release that force instantly. Technicians train specifically for this step, and it's the most dangerous part of the job.
The sizing matters just as much. A spring that's even slightly wrong for your door's weight will strain the opener, wear out fast, or slam the door. Matching wire size, coil length, and wind direction takes measurements most homeowners never make, and door makers like Amarr warn against DIY spring work in their own safety guides.
Rust makes it worse. Antioch's humid summers corrode springs from the inside out, so a spring in Hickory Hollow or near Percy Priest Lake can look fine and still be weakened. Corroded metal behaves unpredictably under tension, which is one more reason to leave it to a pro. If your opener has been straining against a failing spring, it may need attention too. See our garage door opener repair page for what that visit covers.
What a professional spring service visit includes
A professional spring visit in Antioch takes about one to two hours. The technician inspects the door, cables, and drums, sizes the correct replacement spring for your door's weight, releases the old spring's tension with proper winding bars, installs the new spring, and balances and tests everything.
- Inspect the full system: door, springs, cables, drums, and rollers, since a snapped spring often stresses the rest.
- Disconnect and secure the opener so the door can't move during the work.
- Release the old spring's tension with proper winding bars, then remove the broken spring. This is the step that makes the job dangerous for anyone untrained.
- Install correctly sized replacement springs, often in pairs so both sides wear evenly.
- Wind the new springs to the correct tension and set the door's balance.
- Test by hand first, then reconnect the opener and verify the door opens, closes, and reverses safely.

What homeowners should never do with a broken spring
A broken spring turns your garage door into dead weight, and the wrong move can damage the opener, the door, or you. Do none of these while you wait for a technician, even if you're handy. Every one of them makes the eventual repair bigger, more expensive, or more dangerous.
- Don't keep running the opener. It will strain the motor and can burn it out.
- Don't try to wind, unwind, or remove the spring yourself, even with online videos guiding you.
- Don't force the door up if it feels extremely heavy. A falling door can cause serious injury.
- Don't prop the door open with ladders, boards, or clamps. They slip.
- Don't order a random spring online. Spring sizing is specific to your door's weight and dimensions, and the wrong one creates new problems.

Frequently Asked Questions
How can I tell if my spring is broken or just worn out? A broken spring shows a visible gap in the coil, a loud bang you probably heard, and a door that's suddenly very heavy. A worn spring just makes the door sluggish or noisy. If you're unsure, don't test it by forcing the door. Call (615) 576-1762 and we'll check it safely.
Can I open my garage door manually with a broken spring? Only with extreme care, and only if you must. Pull the red release cord with the door fully closed, then lift slowly. If the door feels very heavy or won't stay up on its own, lower it gently and leave it alone. A free-falling door can cause serious injury.
How long does a professional spring replacement take? About one to two hours for most Antioch homes. That covers the full inspection, removing the broken spring, installing the correctly sized replacement, and balancing and safety-testing the door.
Should both springs be replaced if only one broke? Usually yes. Springs on the same door share the same age, cycles, and exposure to Antioch's humidity, so the second one is rarely far behind. Replacing both at once saves you a second service call a few months later.
What does broken spring repair cost in Antioch? Spring service falls within our upfront $139-$399 pricing. The exact number depends on your door's size and spring type, and you'll know it before any work begins. Call (615) 576-1762 for a quote.
