If you've noticed your garage door feeling heavier lately or heard a loud bang from the garage, a snapped spring is likely the culprit. But before you call for a repair, you should know that not all garage door springs are created equal. Torsion and extension springs work in completely different ways, and installing the wrong type will waste money and create safety headaches down the road. Understanding which one your door uses is the first step to getting an accurate estimate and avoiding overpaying.
Torsion springs and extension springs serve the same job (counterbalancing your door's weight) but operate on opposite principles.
Torsion springs wind tightly around a metal rod mounted above your garage door opening. When you open the door, they twist and store energy, then slowly release that energy as the door closes. Think of it like winding a clock. Extension springs, by contrast, hang vertically on both sides of your door track. They stretch and contract as the door moves up and down, similar to how a rubber band works. The mechanics are fundamentally different, which means repair costs, lifespans, and safety profiles diverge significantly.
Most modern homes in Duncanville use torsion springs because they're more reliable and safer. But plenty of older homes still rely on extension springs. If you're unsure which type yours has, look above the door opening. A horizontal rod with springs coiled around it means torsion. Springs hanging along the sides of the tracks mean extension.
Torsion springs typically last 7 to 9 years and cost $200 to $400 per spring to replace. Extension springs last 5 to 7 years and run $100 to $200 per spring. That's cheaper upfront, but you'll replace them more often. Over a decade, the total cost often favors torsion springs even though the initial expense is higher.
The real wallet-killer is mixing types. If your door came with torsion springs and you install extension springs (or vice versa), your door won't balance properly. This creates extra strain on the opener, leads to a snapped spring sooner, and can damage the tracks. You'll end up paying for the wrong repair plus the correct one.

Extension springs aren't bad. They're just better suited to specific situations. Older garage doors, especially those with lighter single-panel designs, often came with extension springs. If your door is 15 or 20 years old and has never had a major repair, extension springs might be original equipment. Replacing them with the same type keeps your setup simple and cheap.
However, if you're upgrading your opener or planning to keep your door long-term, switching to torsion is worth the extra $100 to $200. Torsion springs handle power openers better, require less maintenance, and break less frequently. They're also safer. When a torsion spring snaps, it stays in place. When an extension spring fails, it can whip across the garage with dangerous force.
The safest approach is matching your new spring to whatever type your door was engineered for. Your door's manual or the manufacturer's label will specify. If you've already had work done and don't have records, a professional inspection takes 15 minutes and costs nothing.

Spring type isn't the only variable affecting cost. Your door's weight, the number of springs needed, and your location within the Dallas area all factor in. A heavy custom wood door might need stronger (and pricier) springs than a standard steel model.
Labor is another piece. Torsion spring installation requires special tools and expertise. Improper installation can result in an unbalanced door or premature failure. Extension springs are easier to install, which is partly why some inexperienced contractors push them. This is precisely why garage door spring safety and DIY attempts often fail, the temptation to save money by doing it yourself or hiring an unlicensed handyman leads to bigger problems.
Getting a free estimate before committing saves hundreds. When you call, mention whether your door currently uses torsion or extension springs, and whether you've had recent repairs. This helps the technician prepare an accurate quote.
The best way to know what you need is to schedule a free quote with a professional who can inspect your specific setup. Duncanville Garage Doors can assess your springs, identify the type, check for wear, and give you pricing for same-day repair if needed. You'll know exactly what you're paying for instead of guessing or overpaying for the wrong solution.
If your door is currently working but you're thinking ahead, a spring inspection during routine garage door maintenance prevents emergency repairs down the road. Catching a weak spring early costs far less than replacing a snapped one at midnight.

Can I replace just one spring if both are the same age? No. Springs wear evenly over time. If one snaps, the other is near failure. Replacing both simultaneously ensures balanced operation and prevents a second breakdown within weeks. It costs more upfront but saves money long-term.
How do I know if my spring is about to break? A door that's harder to open, makes creaking sounds, or feels unbalanced often signals failing springs. Don't wait for a snap. A professional inspection identifies weak springs before they fail.
Is torsion always better than extension? Torsion is more durable and safer for most modern doors, but extension springs work fine for lightweight, older doors. The key is matching the spring type to your door's design and weight.
Can I upgrade from extension to torsion springs? Yes, if your door's structure supports it. A professional can assess whether your door is compatible and handle the conversion. It costs more upfront but improves reliability.
What's the average cost of garage door springs near me in Duncanville? Torsion springs run $200 to $400 per spring with installation. Extension springs cost $100 to $200 per spring. Labor and diagnostics add $100 to $150. Get a free estimate for your specific door.
