How to Know When Your Garage Door Springs Need Replacing
Your garage door springs do the heavy lifting — literally. They counterbalance the full weight of the door (often 150–250 lbs) every time it opens and closes. Over time, they wear out. Here's how to know when yours are due for replacement.
1. The Door Won't Open or Feels Extremely Heavy
If your garage door suddenly won't open, or it feels like it weighs a ton when you try to lift it manually, a broken spring is the most likely culprit. The springs bear most of the door's weight — without them, the opener motor alone can't lift it.
2. You Heard a Loud Bang from the Garage
A snapping garage door spring sounds like a gunshot or a car backfiring. If you heard a sudden loud bang from your garage and nothing looks visibly wrong, check your springs. A broken torsion spring will have a visible gap in the coil.
3. The Door Opens Unevenly or Crooked
If one side of your door lifts higher than the other, one of your extension springs may have broken while the other is still intact. This puts dangerous stress on the remaining spring, tracks, and opener. Don't continue using the door — call for service immediately.
4. Visible Wear: Gaps, Rust, or Stretched Coils
Inspect your springs visually:
- Gap in the coil — the spring has snapped
- Rust — corroded springs are weaker and more likely to break without warning
- Stretched or elongated coils — the spring is losing tension
- Wobbling or loose spring — the mounting hardware may be failing
5. The Door Closes Too Fast or Slams Shut
Springs control the speed of your door's descent. If the door drops quickly or slams shut, the springs have lost their counterbalancing force. This is both a safety hazard and a sign of imminent spring failure.
6. Your Springs Are Over 7–10 Years Old
Standard torsion springs are rated for about 10,000 cycles (one cycle = one open + one close). If your household opens the garage door 4 times a day, that's roughly 7 years of life. High-cycle springs last longer, but all springs eventually wear out.
⚠️ Never attempt to replace garage door springs yourself. Springs are under extreme tension and can cause serious injury or death if handled improperly. Always call a licensed technician.
What to Expect from a Professional Replacement
A typical spring replacement takes 45–90 minutes. The technician will:
- Secure the door and release tension from the old springs
- Remove and replace the springs (we recommend replacing both at the same time)
- Lubricate and balance the door
- Test the opener, safety sensors, and manual operation
Cost typically ranges from $150 to $350 depending on the spring type and door size. We provide a written estimate before any work begins.
