Springs do the heavy lifting, not the opener. Every time your door moves, the spring twists or stretches. After enough trips, the steel fatigues and lets go, usually on a cold morning.
Torsion springs sit on a steel shaft above the door opening. They wind up as the door closes and unwind to lift it. Extension springs run along the horizontal tracks on each side and stretch when the door comes down. Older Baldwin homes with low ceilings often still have extension springs, and many of them are missing the safety cable that keeps a broken spring from whipping across the garage.
Near the water in Baldwin Harbor and south of Merrick Road, salt air adds rust to normal wear. A rusted coil grinds against itself and snaps sooner. For homes close to Middle Bay we usually suggest galvanized or coated springs, which hold up better in damp, salty air.
How long do garage door springs last?
A standard spring is rated for about 10,000 cycles. One cycle is one trip up and one trip down. For a family that uses the garage four times a day, that works out to roughly seven years. High-cycle springs rated for 25,000 or more cycles cost a little more and can last two to three times as long.
Should both springs be replaced at once?
On a two-spring door, yes. Both springs were installed together and have made the same number of cycles. When one breaks, the other is close behind. Replacing the pair saves a second service visit and keeps the door evenly balanced.
