It usually starts with a bang from the garage, loud enough that people mistake it for something falling. The next morning the door will not open, or lifts a few inches and stops. Nine times out of ten that is a broken torsion spring, the most common garage door failure we see across South Florida.
How to tell the spring is broken
- You heard a loud bang. A torsion spring under tension releases with a sound like a firecracker when it snaps.
- The door feels extremely heavy. Springs carry almost the whole weight of the door. Without them a double door can weigh over 150 pounds at the handle.
- There is a visible gap in the coil. Look at the spring on the shaft above the door. A broken spring shows a clean two inch separation in the middle of the coil.
- The opener strains, then reverses. Openers are not built to lift a dead door, and most modern units sense the load and stop.
- The door rises crooked. On two spring doors, one broken side lifts unevenly and can jam the tracks.
Garage door spring snapped? What the bang means
A garage door spring that snapped makes one loud crack, often at night when the garage is quiet, and people regularly walk out expecting to find a shelf on the floor. The sound is the torsion spring releasing the stored lift for a 150 to 250 pound door in a fraction of a second. Once the spring has snapped the door is not dangerous on its own, but it is now dead weight: the cables go slack, the opener cannot lift it, and the top panel bends if you keep pressing the button. Look above the door from a safe distance with the door closed. A snapped torsion spring shows a clean gap of two or three inches in the coil. A snapped extension spring, the stretched type that runs along the tracks in older Boca Raton homes, usually hangs loose on one side and the door sits crooked. Either way the next step is the same: leave the door where it is and book a garage door spring replacement.
What to do right now
- Stop using the opener. Forcing it can burn out the motor and bend the top panel, turning a spring job into a spring plus opener plus panel job.
- Leave the door where it is. If it is closed, leave it closed. If it is stuck partway, do not walk or park under it.
- Do not disconnect the red release cord while the door is up. With a broken spring, pulling the release on an open door lets it free fall.
- Keep kids and pets out of the garage until the door is repaired.
What a safe fix looks like
A proper spring replacement is more than swapping the broken coil. We replace springs in matched pairs, because when one spring has reached the end of its cycles its twin is close behind. We then rebalance the door by hand so it holds steady at any height, check the cables and drums that took the shock of the snap, and safety test the opener force settings.
In South Florida, standard springs rated for about 10,000 cycles often age faster because salt air and humidity corrode the steel. High cycle springs rated for 25,000 to 50,000 cycles cost a little more and usually outlast the door itself.
What it costs to fix a broken garage door spring
Most torsion spring replacements in Palm Beach County run about $200 to $500 for the pair, installed, balanced and warrantied. You can see how that compares to other repairs in our garage door repair cost guide, and the full service details on our garage door spring replacement page. If the car is stuck inside and you need the door open today, our emergency garage door repair team covers Boca Raton and the rest of Palm Beach County the same day.
Torsion spring or extension spring, and how to tell which one broke
Almost every garage in South Florida uses one of two systems, and the repair is different for each. A torsion spring sits on a metal bar mounted horizontally above the door opening. Most doors built here since the 1990s use one or two of them. When a torsion spring breaks you will usually see a clean gap of two or three inches in the coil, as if someone cut it, and you may have heard a bang loud enough to be mistaken for something falling in the garage.
Extension springs run along the horizontal tracks on either side of the door, stretched out rather than coiled. Older Boca Raton homes, especially the 1960s and 1970s builds around Boca Raton Square and Winfield Park, still run these. A broken extension spring usually hangs loose, and the door often sits crooked because one side lost its lift while the other did not.
If you cannot see either clearly, do not go looking with the door up. Check from a safe distance with the door closed. Either way the answer is the same, the door should not be operated until the spring is replaced. Either way the fix is the same visit: our torsion spring replacement in Boca Raton is done in matched pairs, usually within the hour.
Garage door spring broken on one side: do both need replacing?
Yes, on a two spring door we replace both, and it is not an upsell. When a garage door spring is broken on one side, the other spring has the same age, the same cycle count and the same salt air exposure, and in our experience it follows within months. Replacing only one also leaves the door unbalanced, because a new spring and a worn spring pull unevenly, which is what makes the door rise crooked and wears out the opener. A matched pair costs a little more on the day, saves a second service call, and the labor carries our 3 year workmanship warranty.
Can you still open the door with a broken spring?
Physically, sometimes. Safely, no. The springs carry essentially the entire weight of the door, and a double garage door weighs between roughly 150 and 250 pounds. With the spring gone, that weight is held by nothing but the cables and whatever the opener can drag. Lifting by hand means holding that full load yourself, and if it slips it comes down fast.
The opener is the other casualty. A garage door opener is built to guide a balanced door, not to lift a dead weight. Running it against a broken spring is the single most common way people turn a repair that costs a few hundred dollars into one that also needs a new opener.
How do I open a garage door if the spring is broken?
Only if you must, and only with help. Pull the red emergency release cord so the opener is disconnected, then have two adults lift the door evenly from the bottom edge, one on each side. A double door with a broken spring can weigh well over 150 pounds at the handle, and it will drop the instant you let go, so prop it with a ladder or clamp locking pliers onto the track under the bottom roller before anyone walks under it. If the door is too heavy to lift smoothly, stop: that is the point where people get hurt and top panels get bent. Call us and we will get the car out when we arrive.
Is it common for garage springs to break?
Yes. A broken torsion spring is the single most common garage door repair we do across Boca Raton and Palm Beach County. Standard springs are rated for about 10,000 cycles, which a family door uses up in 7 to 12 years, and South Florida humidity and salt air shorten that. If one spring on a two-spring door breaks, the other is the same age and usually goes within months, which is why we replace them as a pair.
Why springs break, and roughly when yours is due
Springs are rated in cycles, one cycle being one full open and close. A standard spring is rated near 10,000 cycles. A household that opens the door four times a day reaches that in about seven years, and a busy family with two drivers can get there in five. So a spring breaking is usually not a defect, it is the part reaching the end of a life measured in use rather than years.
Two local factors shorten it. Salt air east of Federal Highway pits the steel and rusts the coils from outside in, which is why coastal Boca and Highland Beach doors tend to fail earlier than inland ones. And heat cycling in an unconditioned garage works the metal every day. When one spring on a two-spring door breaks, the second one is the same age and has done the same work, which is why replacing them as a pair is standard practice rather than an upsell.
Why this specific repair is not a DIY job
Most garage door work is approachable. This part is not. A torsion spring under tension stores a serious amount of energy, and it is released through winding bars in a controlled sequence. The failure mode when it goes wrong is not a scraped knuckle. Winding bars have broken wrists and worse. The tools are also specific, correct-diameter winding bars and a properly sized replacement matched to the door weight, not a hardware store approximation.
The second reason is that a mismatched spring will work and still be wrong. A spring rated for the wrong weight leaves the door unbalanced, which quietly destroys the opener over the following months and puts the whole system out of adjustment.
How long the repair takes
A standard torsion pair on a residential door is usually a one visit job of about an hour on site. That includes removing the broken spring, fitting the matched pair, winding to the correct tension, rebalancing the door so it holds position halfway, and safety testing the reverse mechanism. Extension spring systems are similar, with safety cables added if the door does not already have them. We carry the common Boca sizes on the truck, which is why most spring calls here finish the same day they come in.
