Not if it falls fast.

A door that drops quickly has lost most of its spring tension. Keep people and cars out from under it and call.

Three things to do now

  • 1. Do the balance test Opener off, door to waist height, let go.
  • 2. Don't prop it open If it slips off a prop, it comes down hard.

04 Questions

Balance questions

Why won't my garage door stay open?

Usually the springs have lost tension, so the door drifts down and the opener carries the difference. On a two-spring door, one may already have broken. Chen Garage Door adjusts or replaces springs in San Rafael and across Marin, with springs from $225.

Can the spring tension just be adjusted?

Sometimes, when the spring is sound and simply under-wound. A spring near the end of its cycle life needs replacing, and you hear which at the visit.

Is a drifting door safe to use?

A slow drift is a warning. A fast fall is a hazard: stop using the door and call (510) 509-9998 any hour.
