How long do garage door springs last in Franklin?
Cycles decide it, not years. The builder-standard coil is rated at 10,000 cycles, which is seven to twelve years for a household opening the door four or five times a day, and closer to five years at eight or nine openings. Two things shorten it here: a garage used as the main entrance, and rust in the gap between the coils, which raises friction and spends cycle life faster than the count suggests. A 20,000 to 25,000 cycle coil adds an estimated $60 to $120 and roughly doubles the interval.
Counted in openings, not birthdays
Two springs fitted the same week can be years apart at the end, because the count is the wear. Four openings a day is roughly 1,500 cycles a year, so a 10,000 cycle coil has a decade in it. The three-bay carriage-house facades through Westhaven, Berry Farms and Ladd Park get used as the family front door, and eight or nine openings a day halves that figure. Those doors run out of rating on cycle count long before anything on them looks old.
Corrosion is what makes the rated number optimistic in a Franklin garage. The space is unconditioned, it holds humid air most of the year, the coil is bare steel, and a film of rust in the gap between the turns means every cycle drags where it used to slide. Friction spends cycle life. So the spring arrives at the end of its count early, and then lets go on the first properly cold morning, when the steel is stiff and the bottom seal is stuck to the slab. The cold is the trigger, not the cause.
When the heavier coil is worth it
A high-cycle spring is wound from heavier wire over a longer barrel and rated at 20,000 to 25,000 cycles, for an estimated $60 to $120 more at fitting. On a third bay that opens twice a month, that is money spent on nothing. On the door the family drives through twice a day it usually saves a call-out, and a light spray on the coils once a year keeps rust out of the gap and protects what you paid for. Planning figures, not a quote.
