Garage Door Spring Repair in Green Bay, WI

Broken torsion and extension springs — the most common failure here and the one not to touch.

A garage door does not lift on the opener's strength. The springs counterbalance the door's weight and the opener only overcomes what is left. That is why a door with a broken spring either will not move or moves and then slams: the counterweight is gone and a motor sized for a few pounds is suddenly facing one to four hundred.

In northeast Wisconsin these fail on a schedule. A torsion spring is rated in cycles, commonly about ten thousand, which is roughly seven to ten years for a household opening the door a few times a day. Each cycle leaves a little fatigue in the steel. Cold does not create that damage; it removes the margin. Steel loses toughness as temperature drops and the coil contracts, adding stress precisely where the fatigue already sits. A sound spring does not snap because it got cold. One that was nearly finished does.

The practical consequence is that this is a seasonal maintenance item rather than an emergency. If your springs are past about seven years, they are worth looking at in October rather than discovering on the first ten-degree morning with a car behind the door.

Expect roughly $200 to $400 installed for a single torsion spring and $300 to $600 for a matched pair on a double door, varying with wire gauge, length and cycle rating. A twenty-thousand-cycle spring costs modestly more and roughly doubles the expected life, which in this climate is worth the difference.

When one of a pair breaks, replacing both is honest advice rather than an upsell. Both were fitted at the same time and have taken the same number of cycles, so the survivor is near the end too.

This is the one repair where the advice is simply do not. A wound torsion spring stores enough energy to break bones, and the winding bars become projectiles if they slip.
