A spring failure announces itself: a sharp bang in the garage, then a door the opener strains at and cannot lift. Springs carry almost the whole weight of the door, and a broken one leaves that weight with nothing to hold it but you. Do not force the door and do not try to rewind anything — a torsion spring stores enough energy to break bones, and this is the one garage repair that should never be a weekend project.
We replace springs from measurement, not from a guess off the box: the door is weighed, and wire size, inside diameter and length are matched to it. On a two-spring door both are replaced together, because they have worked the same cycles. Then the door is balanced until it floats at mid-travel and cycled on the opener before we leave.
Signs You Need Garage Door Spring Repair
- A bang like a dropped plank, then the door will not rise
- A visible gap in the coil above the door
- The opener hums and the door lifts a few inches only
- The door slams down fast instead of easing closed
- Loose or slack cables hanging beside the door
- Springs looking dry, dull or rust-spotted
⚓ The Bay-Edge Factor
With no freeze to crack the steel, springs here fail on cycles — and Mountain View households run a lot of them. Two commuters, a home office in the converted half of the garage, kids with bikes and a car charging every night can push a door past four or five cycles a day, so a standard spring that lasts a decade elsewhere is spent in six or seven years. Near the bay, surface rust adds friction between the coils. For busy doors we recommend high-cycle springs, and we always explain the trade-off first.
