If your garage door suddenly won't open, makes a loud bang, or hangs unevenly, there's a good chance your garage door springs are to blame. Springs are the hardest-working component in your garage door system — they bear the full weight of the door every single time it opens and closes. When they fail, the results can range from an inconvenient stuck door to a genuine safety hazard.
This guide explains how springs work, how long they last, and the key signs it's time to call a professional for spring replacement.
How Garage Door Springs Work
Most residential garages use one of two spring types:
- Torsion springs — Mounted horizontally above the door opening, they twist and store energy as the door closes, then release it to help lift the door. Most modern homes use torsion springs because they're safer and last longer.
- Extension springs — Mounted on both sides of the door track, they stretch to create tension. Older homes often have these. They're more likely to break suddenly and fly off, which is why safety cables are strongly recommended.
Both types are under enormous tension — typically hundreds of pounds of force. This is why spring replacement is not a DIY project.
How Long Do Garage Door Springs Last?
Springs are rated by cycle count. One cycle = one open + one close. Most standard springs are rated for:
- 10,000 cycles — the industry standard for basic springs
- 25,000–50,000 cycles — high-cycle springs available as upgrades
If you use your garage door twice a day, standard springs last about 7–12 years. More frequent use shortens that lifespan considerably. Cold Chicago winters also accelerate wear — the metal contracts and expands with temperature swings, weakening the spring over time.
6 Warning Signs Your Springs Need Replacing
1. Loud Bang from the Garage
A sharp, explosive bang — sometimes compared to a gunshot — is the most dramatic sign of a broken spring. A torsion spring under tension can snap suddenly with tremendous force. If you hear this sound, do not try to open the door.
2. Door Won't Open (or Only Opens a Few Inches)
If your electric opener struggles, makes a grinding noise, or the door only lifts 6 inches before stopping, the opener's built-in safety mechanism has detected that the door is too heavy to lift safely. A broken spring is the most common cause.
3. Visible Gap in the Torsion Spring
Walk into your garage and look above the door. A working torsion spring is a continuous coil. A broken one will have a visible gap — typically 2–4 inches — in the middle of the coil. This is an unambiguous sign the spring has failed.
4. Cables Are Loose or Dangling
The lift cables on either side of your door work in conjunction with the springs. When a spring breaks, the cables lose tension and hang slack. You may see them piled on the floor or hanging loosely along the tracks. Loose cables are a secondary failure sign — the primary cause is almost always a broken spring.
5. Door Looks Crooked or Sits Unevenly
If only one of your extension springs breaks (on a two-spring system), the door may still open partially but will hang visibly crooked. One side will be lower than the other, and the tracks will look uneven.
6. Door Feels Unusually Heavy
You can test this by manually disconnecting the opener (pull the red emergency release cord) and trying to lift the door by hand. A properly balanced door should feel like it weighs about 8–10 lbs and should stay at mid-point when you let go. If it feels extremely heavy or falls immediately, the springs are failing.
Why You Should Never Replace Springs Yourself
We get it — YouTube makes everything look doable. But garage door spring replacement is consistently listed among the top causes of DIY home repair injuries. Here's why:
- Extreme stored energy — A torsion spring holds 150–300+ lbs of torque. If the winding bar slips or the spring snaps during installation, the energy releases explosively.
- Proper tools required — Correct installation requires specialized winding bars sized to the spring. Improvised tools (screwdrivers, rebar) are the main cause of accidents.
- Matching specifications matters — The wrong spring size, wire diameter, or length will result in an unbalanced door that wears out your opener prematurely and creates dangerous conditions.
A professional spring replacement typically takes 1–2 hours and costs far less than an ER visit or a damaged vehicle.
