Identify the fault before choosing the repair
Professional Roller Shutter Repair
A faulty roller shutter is more than an inconvenience. In a shop it can mean lost sales; in a warehouse or factory it can block goods movement or leave the premises unable to be secured at the end of the day. Before recommending any work, Unity Shutters diagnoses the underlying fault — because the visible symptom is often not the real cause.
A shutter that will not move may have a worn spring, a failed motor, a blocked track or an electrical fault. We inspect the complete system, explain what we find, and give you a clear choice between repair and replacement before any work begins.
Common Roller Shutter Problems We Repair
These are the faults we most often attend. Every shutter is diagnosed on site before we confirm the repair, so the description of the problem is only the starting point.
Shutter Will Not Open or Close
A shutter that refuses to move can be mechanical, electrical or both. The curtain may be jammed in the guides, a spring may have lost tension, the motor may not be receiving power, or the controls may have failed. We test the system to isolate the cause rather than assuming a part needs replacing.
Stuck or Jammed Roller Shutter
Debris in the tracks, a bent slat, a displaced curtain or a seized bearing can jam a shutter partway. Forcing it usually makes the damage worse. We free the shutter carefully, identify what caused the jam, and repair the cause so it does not return.
Shutter Moves Unevenly or Comes Off Track
When one side runs ahead of the other, the curtain is likely misaligned in its guides or the shaft is out of level. If left, a shutter can come off the tracks entirely. We realign the curtain, check the guides and confirm the shutter tracks evenly along its full travel.
Noisy, Slow or Jerky Operation
Grinding, rattling or slow movement usually points to worn bearings, a dry chain or drive mechanism, or a motor struggling under load. The noise tells us which component needs attention. We inspect, lubricate or replace the affected part and test the operation.
Damaged or Misaligned Slats
Individual slats can be dented, bent or knocked out of alignment by impact. Where the profile allows, damaged slats can be replaced rather than the whole curtain. We match the existing profile and confirm the curtain rolls and seals correctly afterwards.
Broken Springs, Chains or Manual Mechanisms
Manual shutters rely on springs and chain mechanisms, and these wear with use. A broken spring leaves a shutter heavy, uneven or unsafe to operate. We replace springs, chains and operating mechanisms with parts matched to the shutter, and test the manual operation.
Electrical, Switch or Control Faults
An intermittent or unresponsive shutter is often an electrical problem: a faulty switch, a tripped breaker, a control panel error or a wiring issue. We check the electrical circuit and controls as part of the diagnosis, and repair or replace the faulty component.
Roller Shutter Parts We Can Repair or Replace
Where a component cannot be repaired safely, we replace it. The parts we commonly work on include:
- Motors — diagnosis, repair or replacement
- Slats or curtains — damaged slat replacement and curtain realignment
- Side guides and tracks — cleaning, straightening and realignment
- Bearings — replacement when worn or seized
- Springs — replacement and tension adjustment
- Shafts — replacement when bent or worn
- Chains — replacement and lubrication
- Bottom bars — replacement if damaged
- Limit switches — adjustment or replacement
- Controls and switches — repair or replacement
- Wiring and safety devices — checks and replacement of faulty components
Types of Shutters We Repair
We repair all brands and types of manual and motorised shutters, including aluminium, steel, polycarbonate and perforated profiles, roller grilles and fire-rated shutters. Our repair work covers residential, commercial and industrial properties across Singapore, including shopfronts, warehouse doors, factory openings and loading areas. We also accept shutters supplied and installed by other companies. If you are unsure whether we can support your shutter, send us the details and we will confirm before arranging a visit.
Our Roller Shutter Repair Process
We separate diagnosis from repair deliberately: we will not recommend work until we know what is wrong.
Initial Fault Information
You tell us what the shutter is doing — whether it is stuck, noisy, slow or unresponsive — plus the shutter type and location. This helps us prepare for the visit and bring the right test equipment.
Site Inspection and Diagnosis
A technician inspects the shutter, its components and its controls, and identifies the underlying fault. This is the point at which we distinguish between what can be repaired and what should be replaced.
Repair Options and Quotation
We explain the fault, present the repair options and provide a quotation before work begins. You approve the scope and cost first — there are no surprise charges.
Repair or Component Replacement
Approved work is carried out, whether that is adjustment, repair of an existing part or replacement of a component.
Operational and Safety Testing
After the repair we test the shutter through its full travel, confirm the safety devices work and check manual and automatic operation where fitted, before handing the shutter back.
Repair or Replace the Shutter?
Weighing repair against replacement depends on the shutter, not a fixed rule. Consider the shutter’s age and condition, the extent of the damage, whether parts are still available, the cost of the repair against the cost and benefit of a new shutter, and the shutter’s safety and reliability. If the same fault keeps recurring, replacement may be the more practical option.
Repair is not always cheaper, and replacement is not always necessary. Our job is to give an honest recommendation based on the diagnosis, the remaining life of the shutter and your budget. We will always explain the reasoning so you can decide with the full picture.
Commercial and Industrial Roller Shutter Repairs
A broken shutter disrupts more than one doorway. In a shop it can stop trade; in a warehouse or factory it can block loading, hold up goods movement and leave stock exposed overnight. We schedule repairs around your operating hours where possible to limit disruption, and we prioritise situations where the premises cannot be secured. Because downtime is expensive, our approach is to diagnose accurately the first time and carry out the work in as few visits as possible.
Request Roller Shutter Repair
To request a repair, tell us:
- Your location
- The shutter type (aluminium, steel, polycarbonate, grille, fire-rated, etc.)
- Whether it is manual or motorised
- What happens when you operate it
- A photograph or short video of the fault, if you can send one
- Whether the property can currently be secured
Use our contact page and we will arrange a diagnosis and quotation.
Complete Diagnosis
The visible symptom is only the starting point. We inspect the shutter system to identify the underlying fault.
Repair or Replace
We explain whether adjustment, component repair or replacement is the practical option before work begins.
Frequently Asked Questions
| Question | Answer |
|---|---|
How quickly can a roller shutter be repaired? | It depends on the fault and parts availability. We diagnose on site and will tell you whether the repair can be completed in that visit or requires parts. |
Can you repair a shutter installed by another contractor? | Yes. We accept shutters installed by other companies and will inspect and diagnose the fault before quoting. |
Why is my roller shutter stuck? | Common causes include a jammed or misaligned curtain, debris or damage in the tracks, a seized bearing, a failed spring or a motor or control fault. Do not force the shutter — a technician should identify the cause first. |
Can individual damaged slats be replaced? | Where the profile allows, individual slats can be replaced rather than the whole curtain. We match the existing profile and test the shutter after the replacement. |
Do you repair both manual and motorised shutters? | Yes. We repair manual mechanisms such as springs and chains, and motorised shutters including motors, controls and wiring. |
What happens if replacement parts are required? | We quote the parts and labour before proceeding. If a part is not immediately available, we will confirm lead time and arrange a follow-up visit rather than leaving the work incomplete. |
Is it better to repair or replace an old shutter? | It depends on the shutter's age, condition and the cost and reliability of a repair. We give an honest recommendation after diagnosis — repair is not always cheaper, and replacement is not always necessary. |
