Your garage door works dozens of times a day, but you probably never think about it until something breaks. When that happens, a snapped spring leaves your door stuck and your vehicle trapped inside. The good news: knowing the difference between torsion and extension springs helps you avoid overpaying for the wrong repair.
Garage doors use one of two spring types to balance weight and lift smoothly. Torsion springs sit horizontally above your door opening and twist to release energy as the door rises. They're mounted on a steel shaft and handle the heavy lifting work. Most modern residential doors in Dallas use torsion springs because they're safer, last longer (7 to 9 years on average), and distribute force evenly.
Extension springs hang vertically on both sides of the door opening and stretch like rubber bands. Older homes and lighter doors sometimes use these. When extension springs fail, the door can drop suddenly, making them riskier in homes with kids or pets. They typically need replacement every 5 to 7 years.
Springs wear out from constant friction and temperature swings. Dallas heat and humidity speed up this process. A snapped spring won't let your door open or close safely. If you hear a loud bang from your garage, that's usually a spring giving out. You'll notice the door feeling heavier, hanging unevenly, or refusing to move at all.
Trying to repair a failed torsion spring yourself is genuinely dangerous. The spring holds hundreds of pounds of tension. Even small mistakes can cause injury. Learn what to expect with emergency garage door service if your door fails unexpectedly.

A single torsion spring replacement typically costs between $200 and $400 in Dallas, depending on your door's weight and the spring's lifespan rating. Extension springs run $150 to $300 per side. Most homeowners replace both springs at once, even if only one failed, because the second one usually follows within months.
Labor makes up roughly 50 percent of your bill. Professional technicians need specialized tools and expertise to safely install springs under tension. Parts themselves are cheaper than you'd expect, but the safety risk makes DIY impossible.

Torsion springs dominate in modern Dallas homes because they offer better safety and durability. They wear evenly and rarely fail suddenly. If one breaks, the other can sometimes keep your door partially functional in emergencies. The initial cost is slightly higher, but longer lifespan means fewer replacements overall.
Heavy doors (over 400 pounds) almost always need torsion springs. Lightweight doors might work with either type, but torsion is the safer bet long term.
Extension springs fit tight spaces where torsion springs won't fit, like narrow garage openings or low ceilings. If your door already uses extensions and works fine, replacement springs cost less upfront. Just expect to replace them more often. Safety cables run alongside extension springs to catch them if they snap, preventing door collapse.
Older homes in the Dallas area sometimes have extension springs because that's what was standard 20 years ago. Upgrading to torsion during replacement improves safety if your garage opening allows it. Ask your technician whether your space permits the switch.
Spring costs depend on door weight, spring type, and whether both springs need replacement. Review our full breakdown of garage door pricing to understand what reasonable estimates look like. Cheap quotes often mean the technician skips safety steps or uses low-quality springs that fail sooner.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Lifespan depends on door weight, frequency of use, and local weather conditions like Dallas heat.
Can I replace just one spring? Technically yes, but both springs wear at similar rates. Replacing both at once costs more upfront but prevents a second failure weeks later. Most professionals recommend replacing both for safety and balance.
Why is spring replacement so expensive? Labor dominates the cost because the work is dangerous and requires specialized tools and training. A technician must safely manage hundreds of pounds of spring tension. Parts themselves are relatively affordable.
What's the difference between a snapped spring and a worn spring? A snapped spring fails suddenly and completely. Your door won't move at all. A worn spring gradually loses strength, making the door feel heavier or hang unevenly. Both need replacement, but snapped springs require urgent service.
Should I upgrade to torsion springs if I have extensions? If your garage opening allows it, yes. Torsion springs are safer, last longer, and wear more evenly. Ask your technician whether your space permits an upgrade during replacement.
