The Role of Garage Door Springs

Garage door springs balance the weight of your garage door, making it possible for the opener or even yourself to lift this heavy object with ease. Imagine trying to bench press 200 pounds without any assistance - that’s roughly how much most residential garage doors weigh. Now imagine doing so several times a day...sounds exhausting, right?This is where our unsung heroes – the springs come into play. They store mechanical energy when your door closes and release it when you want to open up again.

Type Of Springs And Their Lifespan

You'll find two types of springs on most standard residential garages: torsion and extension springs. Torsion ones are mounted above your closed door while extension ones run alongside overhead tracks.

  • Torsion Springs: Typically lasting between 15,000-20,000 cycles (one cycle equals opening and closing once), they tend to have a lifespan around seven years with average use.
  • Extension Springs: These generally last about half as long as their torsion counterparts – approximately 10,000 cycles or three-to-seven years depending on usage.

Symptoms Of A Broken Spring

If your garage door won't open, or if it does but with an unusual struggle, you might have a broken spring. You may also hear a loud bang - the sound of a spring breaking can be startling.Another sign is seeing gaps in what should be tightly wound coils or having one side of your door appear higher than the other when closed.
