Replaced in pairs
We recommend replacing both springs so the second doesn't fail weeks later.
Door re-balancing
The door is balanced by hand so the opener isn't carrying the weight.

We inspect cables, drums and the shaft for damage caused by the break.
Opener force reset
Travel and force limits re-set so the door opens and stops correctly.
