Emergency spring replacement
The snapped spring — the door nobody can lift.
Call 01632 960 391A broken torsion spring is the one fault that leaves the door dead. The opener will strain, the door will not move, and forcing it bends the panels. We carry matched springs to gauge, wind them to the door’s own weight, and balance the door before we leave.
What the visit includes
- Torsion and extension springs, matched to wire gauge and length
- Both springs replaced as a pair — a matched pair fails together
- Cables, bearings and end plates checked on the same visit
- Door re-balanced to float at half-travel before sign-off
Where it sits on the door’s travel
Spring fractured · door dead. At this point the drawing on our homepage reads 0.0 turns still wound in the spring and 143 lb on the cables — the counterbalance the whole system is built around. Get that number wrong and the door fights the opener, the rollers and itself.
