How to Know If Your Garage Door Spring Needs Replacement

Your garage door spring is one of the most critical — and most stressed — components in your entire garage door system. Knowing when it needs replacement can save you from an unexpected failure.

5 Clear Signs Your Spring Needs Replacement

• Loud Bang: A sudden loud bang from the garage, even when the door wasn't in use, almost always means a torsion spring has broken.
• Door is Very Heavy: If your door feels extremely heavy when you lift it manually, the spring is no longer counterbalancing the door's weight.
• Door Only Opens a Few Inches: The opener may be trying to lift but stopping because the spring is broken.
• Visible Gap in the Spring: A torsion spring above the door with a visible 2-3 inch gap has snapped and needs immediate replacement.
• Door is Uneven or Crooked: If one side drops lower than the other when opening, one spring on a two-spring system has likely failed.

Torsion Springs vs Extension Springs

Most modern garage doors use torsion springs mounted horizontally above the door opening. They store energy by twisting. Older systems use extension springs that run parallel to the overhead tracks and stretch to store energy. Both types eventually wear out and both require professional replacement.

How Long Do Garage Door Springs Last?

Standard springs are rated for approximately 10,000 cycles — one cycle equals one complete open and close. At typical usage (4 open/close cycles per day), that's roughly 7 years. High-cycle springs rated to 25,000 cycles are available and can last over 17 years at the same usage rate. Call Garage Mender at (209) 593-4575 to upgrade.

Why You Should Never Replace a Spring Yourself

Garage door springs are under hundreds of pounds of tension. An improperly installed or incorrectly sized spring can snap violently, causing serious injury or death. Always have a licensed, insured technician handle spring work.
