Most people don't think about their garage door until it stops working. Usually, that moment comes at the worst possible time: you're late for work, the weather's turning ugly, or you've got a guest arriving in an hour. Nine times out of ten, a snapped spring is the culprit. After 15 years climbing ladders and diagnosing doors across Schertz and the surrounding Hill Country, I can tell you that springs are the most common failure point we see, and they're also the most dangerous to ignore.
Your garage door weighs 300 to 500 pounds depending on the size and material. That weight doesn't lift itself. A pair of springs, either torsion or extension type, counterbalance the door and make it manageable for your opener to do its job. Without those springs working properly, your opener would burn out in weeks, or worse, the door could crash down unexpectedly.
Springs are under constant tension. They're designed to cycle 10,000 to 15,000 times over their lifespan, which typically runs 7 to 9 years in our Texas climate. That might sound like a long time, but in a household that opens and closes the door twice daily, you hit that limit faster than you'd expect. Heat accelerates wear. In Schertz, where summer temperatures regularly hit the mid-90s, springs degrade quicker than they do up north.
The two main types are torsion springs (wound around a rod above the door) and extension springs (running along the sides). Torsion springs are more common in modern installs and tend to last longer if maintained. Extension springs are cheaper upfront but wear faster and are messier when they fail.
A snapped spring usually announces itself loudly. You'll hear a sharp bang or crack, like a gunshot in your garage. The door will either not open at all or will open unevenly, one side sagging lower than the other. Some doors will open a few inches and then stop dead. That's your opener hitting resistance because it's trying to lift 400 pounds with zero spring assistance.
Other warning signs come earlier if you're paying attention. A door that feels heavier than usual. Slower opening and closing. A slight wobble or shimmy as it moves. These are clues that springs are losing their tension and that a failure is weeks or months away. If you notice any of these, don't wait. A preventive inspection costs far less than an emergency repair.
If your door's stuck or won't budge, we've got a troubleshooting guide that walks through the diagnosis process.

Spring replacement isn't cheap, but it's predictable. A single torsion spring runs between $150 and $250 in parts, plus labor. If both springs need replacement (smart move, since the second one's likely close behind), you're looking at $400 to $600 for the job, installed. Extension springs cost slightly less because the parts are cheaper, but the labor is identical.
That estimate includes a full inspection of your opener, hardware, and cables. We always check for wear on the rest of the system, because a snapped spring often stresses other components. For a detailed breakdown of what you'll actually pay, check our cost guide for garage door repair in Schertz.
DIY spring replacement isn't advisable. Springs carry tremendous force. A mistake can mean a serious injury. I've seen fingers broken, hands caught, and one memorable incident where a spring came loose and put a dent in a truck bed. Let a licensed tech handle it.
The best way to avoid a snapped spring is regular maintenance. Every 6 months, inspect your springs visually for rust, cracks, or uneven gaps in the coils. Keep them lubricated with a silicone-based garage door lubricant. Check that your door opens and closes smoothly without hesitation.
If you're proactive about upkeep, springs last longer. Our garage door maintenance guide covers the full routine and why it pays off in the long run. A tune-up every year can add 2 to 3 years to spring life and catch problems before they strand you.
When springs do fail, call us right away. We offer same-day estimates and repairs for most Schertz homes and can usually get you back in business the same day you call.
How long do garage door springs last? Typically 7 to 9 years with normal use, though Texas heat can reduce that to 5 to 7 years. Frequency of use and maintenance habits also affect lifespan. Springs that receive regular lubrication and inspection often outlast those left untouched.
Can I replace just one spring? Technically yes, but it's not recommended. When one spring fails, the other is usually near failure. Replacing both at once costs slightly more upfront but saves you from a second emergency call in a few weeks.
What's the difference between torsion and extension springs? Torsion springs sit horizontally above the door and twist under load. Extension springs run vertically along the sides and stretch to lift the door. Torsion springs last longer and are safer; extension springs are cheaper but wear faster and are prone to messier failure modes.
Why is spring replacement so expensive? The danger and liability. Improper installation can result in serious injury or property damage. Licensed technicians carry insurance and training. The cost reflects both the skill required and the risk involved.
Can I open my garage door if a spring is broken? Not safely. The door becomes too heavy for the opener and you risk damage to the motor or cables. Some older doors might open partway manually, but the risk of the door crashing down is real. Wait for professional help.
