Let's get into some of the most common causes of jammed roller shutters and expert solutions...
Debris and Dirt in the Tracks
One of the most common causes of roller shutter jamming is dirt or debris in the tracks.
Dust, leaves, small stones, and other foreign objects can accumulate in the grooves and crevices over time, preventing the shutter from moving smoothly.
How UK Doors & Shutters fix it:
A trained technician will carefully inspect the tracks for any obstructions. They will then remove all debris and thoroughly clean the channels to ensure the shutter has a clear path. In some cases, a suitable lubricant may be applied to reduce friction and restore smooth, reliable operation.
Worn or Damaged Components
Over time, the parts and components of roller shutters naturally experience wear and tear. Slats, springs, rollers, and hinges endure constant use, which can lead to cracks, bends, dents, or worn-down elements.
While regular inspections can catch these issues early, eventually most shutters will encounter component wear that affects smooth operation.
How UK Doors & Shutters fix it:
A skilled repair team will identify the faulty components and replace them, restoring the shutter to full working condition. If multiple parts are approaching the end of their lifespan, a comprehensive service may be recommended to prevent recurring issues.
By using a reputable contractor, you can ensure repairs are carried out efficiently, safely, and with minimal disruption to your business.
Motor Failure
For motorised roller shutters, the motor itself can fail after extended use, often causing the shutter to jam or operate inconsistently.
Common causes include overheating, blown fuses, faulty wiring, control system issues, or general wear and tear of motor components. Regardless of the cause, the result is the same: a shutter that won’t function properly.
How UK Doors & Shutters fix it:
Engineers perform a full diagnostic to determine whether the fault lies with the motor, the power supply, or the control unit. Based on their findings, they may repair wiring, replace blown fuses, or install a new motor, restoring the shutter to smooth, reliable operation.
Improper Installation or Alignment
Shutters that were not installed correctly by a reputable company may develop issues such as jamming.
Common causes include misalignment, uneven weight distribution, or loose components, all of which can affect smooth operation and long-term reliability.
How UK Doors & Shutters fix it:
A qualified repair team will carefully assess the shutter’s alignment and identify any installation-related faults. Minor misalignments can often be corrected on-site, while more serious issues may require partial re-fitting or component replacement.
After inspection, a professional will provide a full diagnosis and recommend the best solution to restore smooth, reliable operation.
Lack of Regular Maintenance
Routine inspections and servicing are essential to keep your roller shutters in optimal condition.
Without regular maintenance, issues like dried lubrication, loose bolts, and general wear and tear can lead to more frequent jamming and costly repairs.
How UK Doors & Shutters fix it:
UK Doors and Shutters offer maintenance packages that ensure your shutters are regularly checked and serviced. Our engineers keep your system properly lubricated, identify potential faults early, and address minor issues before they escalate.
Regular maintenance provides peace of mind and ensures your shutters continue to operate smoothly and reliably.
Tips to Prevent Roller Shutter Jamming
Following simple practices can help reduce the risk of your shutters jamming and extend their lifespan:
- Keep the tracks clear: Regularly remove dirt, dust, leaves, and other debris from the shutter tracks.
- Operate shutters gently: Avoid slamming them shut or forcing them open, as this can damage components over time.
- Listen and watch for changes: Unusual noises, uneven movement, or hesitation are early warning signs of potential faults.
- Check for visible damage: Look for bent slats, loose fixings, or signs of rust that could affect performance.
- Arrange periodic servicing: Regular professional shutter servicing can prevent problems before they start and ensure everything is operating safely.
