In our 15 years serving Duncanville, we've seen this problem again and again: a homeowner walks into their garage on an ordinary Tuesday, hears a loud BANG, and suddenly their door won't budge. Garage door springs in Duncanville fail without warning because they're under constant tension, carrying roughly 400 pounds of load. When a torsion or extension spring snaps, you're looking at a door that's basically dead weight. The good news is that replacement is straightforward once you know what to expect, and professional service near me can have you mobile again the same day.
Springs aren't mysterious. They're metal coils that wind and unwind thousands of times, easing your door open and closed. Over 7 to 9 years of normal use, metal fatigues. Heat cycles in the Texas sun accelerate that wear. One day the metal simply fractures, and the door stops working instantly.
You might hear it before you see it. A loud crack or bang from the garage is the classic sign. After that, the door becomes a two-ton liability. Trying to open it manually risks injury. Operating an automatic opener with a broken spring strains the motor and can damage the door itself.
This is why getting a same-day estimate and repair matters. A snapped spring isn't something to postpone. We've served homeowners across Duncanville and Arlington who waited a few days, only to find themselves locked out or dealing with secondary damage.
Two main spring types sit in residential garages. Understanding which you have helps you prepare for cost and repair time.
Torsion springs mount horizontally above your door opening, on a shaft running left to right. They're wound steel tubes that rotate to create lifting force. When a torsion spring fails, the door drops hard and fast. This type is more common in newer homes and handles weight more efficiently. Replacement cost for a single torsion spring typically ranges from $150 to $300, depending on diameter and wire gauge.
Extension springs hang vertically on both sides of the door, stretching and contracting as the door moves. They're older style but still found in many Duncanville garages. Extension springs cost slightly less to replace, usually $100 to $250 per spring, though most doors need both replaced at the same time for balance.
Both types require professional replacement. Attempting a DIY fix risks serious injury. The tension stored in a compressed spring is explosive when released.

Spring replacement isn't expensive, but you need to know where your money goes. Our detailed garage door repair cost guide breaks down typical expenses, but here's what springs specifically cost.
A single torsion spring replacement runs $200 to $350 installed, including labor and the spring itself. Extension springs are typically $150 to $280 per spring. Most homes have either one torsion spring (high-cycle doors) or two extension springs (older doors). If both extension springs are worn, replacing both at once prevents a second failure in six months.
Labor usually accounts for 40 to 50 percent of the bill. We charge travel time for same-day calls, especially if you're in south Duncanville or near the Cedar Hill border. An emergency evening or weekend call costs more, but it beats being trapped outside your garage.

Homeowners often ask whether they should replace both springs if only one snapped. The answer is almost always yes.
If you have extension springs, they're the same age and under the same stress. A second failure is likely within months. Replacing both now saves you from another service call and another repair bill in the near future.
For torsion springs, some doors have a single spring (most common) or two springs (heavier doors). If you have two and one snaps, the remaining spring can't balance the load. The door will bind, and the motor works harder. Replacing both keeps the door moving smoothly and extends opener life.

Springs fail. It's part of owning a garage door in Texas. The difference between a minor repair and a major headache is how fast you act.
How long do garage door springs last? Quality torsion and extension springs typically last 7 to 9 years under normal use. Frequency matters more than calendar time. A door opened and closed 3 to 5 times daily wears springs faster than one used once daily.
Can I replace a garage door spring myself? No. Springs under tension can cause serious injury or death if released improperly. Professional replacement is the only safe option. Specialized tools and training are required.
What does a snapped spring sound like? A loud crack, pop, or bang from the garage when the door fails to open. The door becomes immobile immediately. Some people hear it from inside the house.
How much does spring replacement cost in Duncanville? Single torsion spring replacement runs $200 to $350 installed. Extension springs cost $150 to $280 each. Labor is included. Emergency after-hours service costs more.
Will a broken spring affect my garage door opener? Yes. Operating an opener with a broken spring forces the motor to work harder and can burn it out. Stop using the opener immediately after spring failure.
