Do garage door springs LOSE their “spring”

garage-doorgarage-door-opener

On a one-piece, single-car door that's rarely opened (springs usually stretched), do they eventually stretch, thus stopping the opener from working?

Best Answer

No, they don't measurably stretch. The reason is that, by design, the springs are not extended beyond their elastic limit at any point in the open/close cycle. The amount of "annealing" that takes place over your lifetime is too small to worry about -- or measure.
