Garage door springs carry roughly half the weight of your door. When one snaps, the door becomes a 400-pound liability. This guide cuts through the confusion about garage door springs in Duncanville so you understand what's holding up your door, when replacement is non-negotiable, and what you'll actually pay.
Your garage door uses one of two spring systems. Knowing which one you have matters because they fail differently and carry different safety risks. See our guide on garage door maintenance in duncanville: the complete tune-up guide.
Torsion springs sit above the door opening on a metal shaft. They twist and unwind to lift your door. One torsion spring typically lasts 7 to 9 years with normal use. These are the safer option because the cable system contains a snapped spring, preventing sudden collapse. Most homes in Duncanville use torsion springs.
Extension springs run along the sides of your door tracks. They stretch and contract like rubber bands. Extension springs last 5 to 7 years and are less forgiving. When one fails, the door can drop suddenly because both springs usually fail around the same time, and there's no containment system.

Torsion springs cost more to replace but outlast extension springs by years. If you're unsure which type you have, look above your door opening. If you see a horizontal shaft with coils, that's torsion. If you see springs running parallel to the tracks on each side, that's extension.
Springs wear out through cycles. Every time your door opens and closes, the spring loses a tiny bit of elasticity. After 10,000 to 15,000 cycles, metal fatigue wins.
But Duncanville's heat accelerates failure. Summer temperatures spike above 95 degrees regularly. Metal expands and contracts daily, creating stress fractures invisible to the eye. Rust also speeds deterioration, especially if you skip routine maintenance.
I've seen springs snap with zero warning. One homeowner heard a loud bang at 6 a.m. The door wouldn't budge. Another family discovered a snapped spring when their opener stopped working mid-close. A third called after their door fell hard enough to bend the bottom panel.
For a deeper understanding of how heat impacts your door, read our guide on preparing your garage door for winter, which covers seasonal stress on all components.
A working spring is nearly invisible. When it fails, you'll notice immediately. Watch for these warning signs:
Your door opens only partway before stopping. The opener struggles more than usual. You hear a loud metallic snap or bang. The door feels heavier or moves unevenly. Visible rust or gaps appear where the spring connects to the shaft.
If you spot any of these, stop using the door. A snapped spring can't hold the door safely, and continued use risks injury or equipment damage.

A torsion spring replacement typically runs $200 to $400 per spring in the Duncanville area, including labor. If both springs need replacement (common), budget $400 to $800 total. Extension spring replacement is slightly cheaper at $150 to $300 per spring, but you'll usually replace both.
These prices assume standard residential doors. Wider or heavier doors cost more. Commercial doors cost significantly more.
Many homeowners ask about DIY replacement. I strongly advise against it. Spring replacement involves high-tension systems that store enormous force. A mistake can cause serious injury or death. This is one repair where professional installation isn't optional.
When you call for an estimate, ask if the cost includes a safety inspection of cables and pulleys. A reputable company will check these components at no extra charge because they often fail alongside springs. Learn more about our garage door spring replacement service and what's included.

Your garage door spring isn't a luxury component. It's essential safety equipment. When it fails, call professionals immediately. Waiting risks injury to your family and damage to your door.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Texas heat and frequent use reduce lifespan. The number of cycles matters more than calendar years.
Can I replace just one spring if both are old? No. If one spring fails, the other is near failure. Replacing only one creates imbalanced door movement and strains the remaining spring faster, leading to a second failure soon after.
Is it safe to use my garage door if one spring is broken? No. A snapped spring can't support half the door weight. The door may fall suddenly or open unevenly, creating a collision or pinch hazard. Stop using the door and call for repair.
Why is spring replacement so expensive? Labor is the largest cost. Spring replacement requires specialized knowledge, tools, and safety precautions. The springs themselves are relatively cheap, but professional installation protects your family and door.
