If you've ever heard a loud bang from your garage and walked out to find a door that won't budge, there's a good chance a spring just let go. It's one of the most common calls we get from homeowners near JBSA-Fort Sam Houston. and it makes sense given what our climate does to metal hardware year-round.
San Antonio sits in a part of Texas where summers regularly push into the triple digits and humidity stays stubbornly high from spring through fall. That combination is hard on garage door springs. The metal expands in the heat, contracts during the occasional cold snap in January, and corrodes faster than it would in a drier climate. If your door is more than seven years old, it's worth understanding what's happening with those springs before they fail at the worst possible moment.
Your garage door weighs anywhere from 130 to over 300 pounds depending on the material. Springs are what make it possible for you. or your opener. to lift that weight with minimal effort. There are two main types:
- Torsion springs mount horizontally above the door opening and use torque to help lift and lower the door. They're the more common setup on newer homes in the San Antonio area and tend to last longer. - Extension springs run along the sides of the door on tracks. They're common on older homes, including some of the historic housing near Fort Sam Houston where detached garages with older door systems are still in use.
Most standard springs are rated for around 10,000 open-and-close cycles. If your household uses the garage as a primary entry point. which most families living near JBSA-Fort Sam Houston do. you can burn through that cycle count in seven to ten years.
Don't wait for the loud snap. These are the signs that your springs are on their way out:
The door feels unusually heavy. If you disconnect the opener and try to lift the door manually, it should stay put when raised halfway. If it drops, the spring tension is off.
The door moves unevenly or jerks. When only one spring fails on a two-spring system, the door will lift at an angle and put stress on the tracks and opener motor.
You hear squeaking, grinding, or a visible gap in the coil. A visible separation in the torsion spring coil is a clear sign it has snapped and needs immediate replacement.
The opener runs but the door barely moves. A broken spring forces the opener to work far harder than it was designed to, and over time that leads to motor burnout. turning a $200 spring repair into a much larger problem.
San Antonio's high humidity doesn't help here either. Moisture in the air contributes to rust and corrosion on metal springs, and once corrosion sets in, a spring that might have lasted another two years can fail much sooner. If you haven't had your springs inspected recently, it's a good idea to check our full services overview to see what a tune-up includes.
You'll find plenty of spring replacement tutorials online, but this is one of those repairs where the risk is genuinely serious. Garage door springs are under extreme tension. When a torsion spring releases unexpectedly, it can snap with enough force to cause severe injury or damage nearby objects.
Beyond the safety issue, getting the spring sizing wrong causes problems too. Using a spring that's too small or too weak for your door's weight will cause it to wear out faster. sometimes within months. A professional measures your door's exact weight and selects the correctly rated spring for your specific setup.

For most single-car garage doors in the San Antonio area, spring replacement runs roughly $150 to $300 depending on the spring type and whether you're replacing one or both. It's generally smart to replace both springs at the same time. if one has failed after 10,000 cycles, the other is right behind it.
Higher-cycle springs (rated for 25,000+ cycles) cost more upfront but can be a smart investment if you're planning to stay in your home for a while or if your household uses the garage door constantly. For military families in Schertz or Converse who PCS every few years, a standard replacement is usually the practical call.

Q: Can I still use my garage door if a spring is broken? A: Technically yes, but you really shouldn't. Using the door with a broken spring puts enormous strain on the opener motor and cables, and can cause additional damage. If the opener is already struggling, continued use may burn out the motor entirely. Disengage the opener and call for service.
Q: How long do garage door springs last in the San Antonio area? A: Most springs are rated for about 10,000 cycles, which works out to roughly 7,10 years for an average household. San Antonio's heat, humidity, and temperature swings can accelerate wear, so homeowners near JBSA-Fort Sam Houston may find springs wearing faster than the national average. Lubricating springs twice a year can help extend their lifespan.
Q: Should I replace both springs at the same time even if only one broke? A: Yes, in almost every case. Both springs experience the same wear over the same number of cycles. If one has broken, the other is near the end of its life too. Replacing both at once saves you a second service call within a year and keeps your door balanced.
