Spring Life Is Measured In Door Cycles
One cycle is one complete opening and closing of the garage door. A spring rated for 10,000 cycles could last many years on a lightly used door but wear out much sooner when the garage is the household’s main entrance.
Manufacturer guidance commonly places standard spring life around 7 to 10 years under typical use, but that is an estimate—not a guarantee. A Burnaby household using the door four times per day adds roughly 1,460 cycles each year.
