Spring Tension — Garage Door Glossary | D&L Garage Doors
**Spring Tension**: The amount of stored energy in a garage door spring, which must be precisely calibrated to counterbalance the door's weight. Understanding this component helps homeowners make informed decisions about garage door maintenance, repair, and replacement. Below, D&L Garage Doors explains what a spring tension is, how it works, common misconceptions, and when to call a professional.
What Is a Spring Tension?
Spring tension refers to the amount of energy stored in the garage door springs. Proper tension is critical — if the springs have too much tension, the door will be difficult to close and may fly open. If there's too little tension, the door will be heavy to lift and may slam down. The goal is for the springs to counterbalance the exact weight of the door, so the door stays in any position when the opener is disconnected. Spring tension is set during installation by winding torsion springs a specific number of turns (typically 7 to 8.5 full turns for a standard residential door) or by adjusting the hook position on extension springs. Over time, springs lose tension as the metal fatigues, which is why garage doors gradually become harder to open. A door that won't stay open halfway when disconnected from the opener likely has weakened springs that need adjustment or replacement.
Common Misconceptions About Spring Tensions
There are several widespread myths about spring tensions that can lead to costly mistakes or safety hazards. Here's what you should actually know:
- Myth: You can adjust spring tension yourself. Reality: Adjusting torsion spring tension requires specialized winding bars and is extremely dangerous.
- Myth: Adding more tension makes the door last longer. Reality: Over-tensioned springs wear out faster and create unsafe conditions.
- Myth: Spring tension doesn't change over time. Reality: Springs gradually lose tension through metal fatigue, typically over 7-10 years.
Safety Warnings
Safety is paramount when dealing with garage door components. Keep these important warnings in mind:
- Never attempt to adjust torsion spring tension without professional training and proper winding bars.
- A door that is too heavy or too light to operate manually indicates a spring tension problem — call a professional.

- Extension Spring — A spring that stretches and contracts along the horizontal tracks on either side of the garage door to counterbalance its weight.
- Garage Door Balance — The condition where the springs precisely counterbalance the door's weight, allowing it to stay in any position when disconnected from the opener.
- Cycle Life — The number of open-and-close cycles a garage door spring or component is rated to perform before expected failure.
When to Call a Professional
While understanding garage door components helps you communicate effectively with technicians and spot problems early, most garage door work should be performed by licensed professionals. Springs, cables, tracks, and opener systems involve heavy components under significant tension.
