Understanding Garage Door Spring Replacement
January 5, 2025 7 min read
Garage door springs are the unsung heroes of your garage door system. These tightly wound metal coils bear the enormous weight of your door, making it possible to open and close smoothly. When they fail, your door becomes inoperable and potentially dangerous. Here's what every homeowner should know about garage door springs.
Types of Garage Door Springs
Torsion Springs
Located above the garage door on a metal shaft, torsion springs are the most common type in modern garage doors. They work by twisting and coiling on the shaft, storing mechanical energy that helps lift the door. Most residential doors have one or two torsion springs, depending on the door's weight.
Torsion springs are generally safer and longer-lasting than extension springs, with a typical lifespan of 15,000-20,000 cycles (one cycle equals one open and close).
Extension Springs
These springs run along the horizontal tracks on either side of the door. They extend and contract to provide lifting power. Extension springs are more common in older installations and on lighter doors.
Because they stretch under tension, extension springs should always have safety cables running through them to prevent a broken spring from becoming a projectile.
Signs Your Springs Need Replacement
The door won't open or opens only a few inches: When a spring breaks, the opener motor alone can't lift the heavy door.
The door opens unevenly: If one spring is weaker or broken, the door may rise crookedly or struggle on one side.
Loud bang from the garage: A breaking torsion spring releases energy suddenly and makes a loud noise, often compared to a gunshot.
Visible gaps in the spring coils: A broken torsion spring will have a visible gap where the coil separated.
Door falls fast when closing: Springs counterbalance the door's weight. Without proper tension, the door will slam down.
Why Spring Replacement Is Dangerous
Garage door springs are under immense tension.enough to seriously injure or kill. The average garage door weighs 150-400 pounds, and all that weight is being held by the springs. A sudden release of this tension can turn spring components into deadly projectiles.
Additionally, specialized tools are required to safely wind and unwind the springs. Without proper training and equipment, attempting spring replacement is extremely dangerous.
The Professional Replacement Process
When you call a professional like Garage Door Anaheim, here's what to expect:
1. Safety first: The technician secures the door in the open position and clamps the tracks.
2. Tension release: Using specialized winding bars, the old springs are carefully unwound.
3. Measurement and selection: Springs must be precisely sized for the door's weight. The technician measures and selects the correct replacement.
4. Installation: New springs are mounted and wound to the proper tension.
5. Balance testing: The door is tested to ensure it opens and closes smoothly and stays in place when partially open.
6. Safety check: All components are inspected and the door's safety features are tested.
Extending Spring Life
While springs eventually wear out, proper maintenance can extend their lifespan:
- Lubricate springs twice yearly with a silicone-based lubricant, Schedule annual professional inspections, Ensure the door is properly balanced, Replace both springs at the same time, even if only one breaks
The Cost of Spring Replacement
Spring replacement typically costs $150-350 for torsion springs and $100-200 for extension springs, including parts and labor. While this might seem expensive, it's far less than the cost of injuries or property damage from a DIY attempt gone wrong.
