In our years serving Tar Heel, we've seen this problem again and again: a homeowner hears a loud bang from the garage, tries to open the door, and nothing happens. A snapped spring is almost always the culprit. The good news? This repair costs far less than replacing the entire door, and addressing it quickly prevents secondary damage to your opener and panels.
Garage door springs work under extreme tension. A typical torsion spring (the most common type in residential homes) handles roughly 10,000 to 20,000 opening cycles before wearing out. That translates to 7 to 9 years for an average household opening the door twice daily.
Springs fail because of:
- Metal fatigue. Springs flex thousands of times. Eventually, the steel loses its elasticity. - Rust and corrosion. Moisture in your garage accelerates deterioration, especially in humid climates. - Poor maintenance. Lack of lubrication makes springs work harder than necessary. - Sudden temperature swings. Cold snaps can make metal brittle.
Extension springs (less common, found on older doors) snap similarly but typically fail faster because they handle load differently than torsion springs.
A snapped spring repair in Tar Heel typically runs between $200 and $400, depending on the spring type and whether both springs need replacement. Single torsion springs cost less to replace than a pair of extension springs.
Why replace both springs even if only one snapped? Because the second spring is likely near failure too. Replacing just one creates imbalance, strains your opener, and wastes money when the second spring breaks weeks later. Most professionals recommend replacing springs in pairs.

Some homeowners consider replacing springs themselves after watching YouTube videos. We strongly advise against it. Springs under tension can cause serious injury if they slip. A professional can schedule a free quote and complete the job safely in under an hour.
The labor cost is worth the safety margin and warranty coverage. If a spring fails within 30 days of repair, most reputable shops replace it free.
Your door won't open or opens very slowly and unevenly. You might hear a loud metallic snap or bang from the garage, sometimes followed by the door dropping suddenly. The remote won't activate the opener because the motor senses the imbalance and stops.
If your door is stuck or won't open, we've covered troubleshooting steps in detail here. Spring failure is just one possible cause, but it's the most common one requiring professional help.
Regular maintenance extends spring life by 2 to 3 years. A simple tune-up includes lubrication, tension checks, and balance testing. For a complete maintenance checklist, see our garage door maintenance guide for Tar Heel.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with average use (opening and closing twice daily). Extension springs wear faster, often lasting 5 to 7 years. Lifespan depends on maintenance, humidity, and temperature swings.
Can I open my garage door manually if the spring is broken? No. A broken spring removes the counterbalance, making the door extremely heavy and dangerous to lift by hand. Always call a professional for broken spring repair.
Why do springs break suddenly without warning? Metal fatigue accumulates silently over thousands of cycles. Springs rarely show signs of wear until they snap. This is why proactive replacement of aging springs prevents surprise failures.
Is it cheaper to replace one spring or both? Replace both. The surviving spring is likely near failure too. Replacing only one creates imbalance, damages your opener, and costs more when the second spring breaks shortly after.
What's the difference between torsion and extension springs? Torsion springs twist to lift the door and sit above it horizontally. Extension springs stretch and sit on the sides. Torsion springs are stronger, safer, and more common in modern homes. Extension springs are found on older single-car doors.
