Your garage door suddenly won't open, or it's stuck halfway. You hear a loud bang from the garage. Nine times out of ten, you've got a snapped garage door spring. A broken spring is not a repair you can DIY, and it's not one you should wait on. This guide covers exactly what happens when a spring fails, why you shouldn't touch it, and how to get help fast in Duncanville.
Garage door springs fail for three main reasons. First, they simply wear out. Most torsion and extension springs last 7 to 9 years with normal use. That's roughly 10,000 to 15,000 cycles (one open, one close equals one cycle). Second, the Texas heat accelerates wear. Springs in Duncanville and the Dallas area cycle faster in summer because metal expands and contracts with temperature swings. Third, imbalance causes premature failure. If one spring carries more load than the other, it snaps first.
When a spring finally breaks, it happens fast and loud. You'll hear a sharp crack or pop. The door becomes impossible to lift by hand. The opener may sound like it's straining but won't budge the door. This is your first warning sign.
Do not attempt to lift the door manually after a spring breaks. A standard two-car garage door weighs 300 to 400 pounds. The springs counterbalance that weight. Without them, you risk serious injury to fingers, hands, arms, or even your head if the door falls. Do not try to adjust the springs yourself. Torsion springs are under extreme tension. If you slip while working on them, the spring can unwind and cause severe cuts or broken bones. Do not ignore the problem hoping it will resolve itself. A broken spring means the door opener is working overtime to compensate, which can damage the opener motor and lead to a much costlier repair down the road.
Instead, stay out of the garage. Turn off the opener if you can do so safely. Call a professional immediately.

Most residential doors use one or two torsion springs mounted horizontally above the door. Some older homes have extension springs running along the sides. Torsion springs are the heavy-duty choice and last longer, but when they snap, the failure is catastrophic. Extension springs are cheaper but wear faster. If your door has extension springs, you may want to upgrade to torsion during your repair. We've seen too many homes with older extension setups that fail repeatedly within a year of each other.
Knowing which type you have helps us give you an accurate estimate over the phone. Take a photo of the spring area if you can do so without entering the danger zone. Send it to our team, or describe the setup. That detail saves time when you schedule a free quote.
A single torsion spring replacement typically costs between $150 and $300 for the part and labor combined, depending on the spring size and your door weight. Extension springs are slightly cheaper, around $100 to $250. Many homeowners are surprised by the cost until they realize that professional installation prevents injury and protects your opener. If you've already damaged the opener by running it with a broken spring, you're looking at an additional $200 to $800 for opener repair or replacement.

A snapped spring often feels like it came out of nowhere, but it usually doesn't. Springs that are about to fail show warning signs. The door may open or close unevenly, favoring one side. You might hear creaking or groaning sounds. The door may drift down slowly when stationary, indicating spring weakness. These are all signals to call for an inspection before a complete failure happens.
Routine maintenance catches these problems early. Our complete tune-up guide covers the inspection checklist and seasonal care steps that extend spring life and keep your door safe.
When you call Duncanville Garage Doors with a snapped spring, here's what to expect. We'll ask for a description and photos. We'll provide an estimate over the phone or schedule a same-day visit depending on your timeline. On arrival, we'll inspect both springs (even if only one snapped, the other is likely close behind). We'll replace the broken spring and test the door balance. A properly balanced door opens and closes smoothly without drifting. We'll also check the cables, pulleys, and opener to ensure nothing else was damaged during the failure.
Most same-day repairs take 1 to 2 hours from arrival to completion.

A broken spring is not a cosmetic issue. It's a safety and security concern that affects your home and your family. Let the professionals handle it.
Can I open my garage door manually if the spring is broken? No. A broken spring removes the counterbalance that makes manual lifting safe. The full weight of the door (300+ pounds) falls on you. Serious injury is likely. Call a professional instead.
How long do garage door springs typically last? Torsion and extension springs last 7 to 9 years under normal use, or roughly 10,000 to 15,000 opening cycles. Texas heat and humidity can shorten this lifespan. Regular maintenance helps maximize durability.
Will my garage door opener get damaged if I run it with a broken spring? Yes. The opener motor will strain to lift a door without spring support. Repeated attempts can burn out the motor, leading to additional repair costs of $200 to $800 or more.
How much does a snapped spring repair cost? Torsion spring replacement averages $150 to $300 including labor. Extension springs run $100 to $250. Costs vary based on spring size, door weight, and whether other components need repair.
Can I replace just one spring if both are old? Technically yes, but we usually recommend replacing both. If one spring fails, the other is likely near the end of its life. Replacing both at once prevents a second emergency repair within months.
