Replacing Garage Door Springs The most common garage door torsion springs have an expected life of about 10,000 “cycles”. A cycle is one opening and one closing of the garage door. The steel spring experiences tremendous force each time the door opens or closes. Gradually, the steel fatigues with each flex, and eventually cracks and breaks, usually releasing its stored energy in an instant with a loud noise or bang. If you need a new garage door spring for your home, don't hesitate to call us. We'll be there quickly and install the new springs properly and for less than you might expect.
