A broken garage door spring is one of those problems that gives you zero warning and demands immediate attention. Your door won’t open, it might be hanging at an angle, and you’re probably wondering what this is going to cost. Here’s the straightforward guide.
How to Tell Your Spring Is Broken
Most homeowners discover a broken spring in one of these ways:
- Loud bang from the garage — A torsion spring breaking sounds like a gunshot. If you heard a bang and your door won’t open, check the spring
- Door won’t open or feels extremely heavy — The springs do the heavy lifting (literally). Without them, the motor can’t raise the door
- Visible gap in the spring — Look at the torsion spring above the door. A broken spring will have a clear gap in the coil
- Door opens a few inches then stops — The opener’s safety mechanism kicks in when it detects too much resistance
- Door closes too fast — If the springs are weakened but not fully broken, the door may slam down instead of lowering smoothly
Torsion vs. Extension Springs
Your garage door uses one of two spring types:
| Feature | Torsion Springs | Extension Springs |
|---|---|---|
| Location | Above the door on a metal shaft | Along the horizontal tracks on both sides |
| Common on | Most standard and double-wide doors | Older installations, some single-car doors |
| Lifespan | 10,000–20,000 cycles | 10,000 cycles |
| Replacement cost | $200 – $450 (pair) | $150 – $250 |
| Safety risk | Very high tension — professional only | Moderate risk — still recommend professional |
| Replacement time | 45–90 minutes | 30–60 minutes |
Most Denton homes built after 2000 use torsion springs. If your home has extension springs, consider upgrading to torsion during replacement — they last longer, operate more smoothly, and are safer.
Replacement Costs in Denton
| Service | Typical Cost |
|---|---|

| Pair of torsion springs | $250 – $450 |
| Extension springs (pair) | $150 – $250 |
| High-cycle torsion springs (25,000+) | $300 – $550 |
| Spring + cable replacement | $275 – $500 |
| Full hardware tune-up with spring replacement | $350 – $550 |
| Emergency/same-day service surcharge | $50 – $100 extra |

Replace both springs at the same time. If one spring broke, the other is the same age and will fail soon. Paying for a second service call in a few months costs more than replacing both now.
Why This Is Not a DIY Job
Garage door torsion springs are one of the most dangerous components in your home. A standard two-car garage door weighs 150–250 pounds, and the springs that counterbalance that weight are under extreme tension.
Every year, DIY spring replacement attempts cause serious injuries across North Texas. The winding bars can slip, the spring can release stored energy violently, and the door itself can drop unexpectedly. Professional technicians have specialized tools, training, and insurance for this work.
The only safe DIY step: disconnect the opener and don’t use the door until a technician arrives.

A few things affect garage door springs in the Denton area more than other regions:
- Temperature swings — North Texas sees 30-degree temperature changes in a single day during spring and fall. Metal springs expand and contract with temperature, which accelerates fatigue
- Heat — Denton garages regularly hit 130+ degrees in summer. Sustained heat weakens spring steel over time, which is why springs in Texas tend to fail slightly earlier than their rated cycle life
- Humidity — Moisture causes corrosion on uncoated springs. If your springs show rust, they’re losing strength. A silicone-based lubricant applied every 6 months helps
How to Extend Spring Life
- Lubricate springs and hinges with silicone spray every 6 months
- Keep the tracks clean and aligned
- Don’t let the door slam — use the opener rather than manually dropping the door
- Get an annual tune-up that includes spring tension adjustment and hardware inspection
- Consider high-cycle springs (25,000+ cycles) at replacement — they cost $50–$100 more but can last 15+ years
Bottom Line
A broken garage door spring costs $200–$450 to fix and takes under two hours. It’s one of the more affordable home repairs, but it’s genuinely dangerous to attempt yourself. Call a pro, replace both springs, and consider high-cycle springs for longer life.
