Guides
When should a roller shutter be repaired or replaced?
Quick answer
Repair is generally appropriate when the fault is localised and the curtain, shaft, guides and box remain sound. Replacement becomes more sensible when failures repeat, several components are worn, or the old system can no longer be adjusted and motorised reliably.
Faults that are often repairable
A broken belt, worn crank, detached hanger, end-limit setting or small guide component can often be handled separately. Diagnosis should still confirm that broader wear is not causing the issue.
Signs that favour replacement
A badly distorted curtain, damaged guides, worn shaft, repeated jams or unavailable parts may justify wider renewal. Fitting a new motor to unstable mechanics does not address the cause.
Compare service life, not only today's invoice
A lower-cost repair is worthwhile when it restores durable operation. Consider how many components are affected, overall condition, parts availability and desired improvements in comfort or control.
Replace one part and retain the rest
The choice is not always all or nothing. Depending on condition, the curtain, control or motor may be replaced while retaining the box and guides, provided the components remain compatible.
What to send for an initial assessment
Photos of the closed shutter, box, guides and controls, plus a description of the noise or jam, help prepare the visit. Around Biel/Bienne, the final decision follows an on-site check.
