A shutter falls off its runners (the metal guides or tracks on either side of the frame) for one of these reasons:
Worn or damaged guides. Over time, the plastic or metal clips that hold the shutter in place wear out, especially in salty coastal air. The shutter slides sideways and derails. This is the most common cause.
Bent or dented track. If the shutter has been hit — a ladder leaning against it, high wind, a child tugging it — the track can bend slightly. This throws the shutter out of alignment. Even a small dent in a metal track can cause the whole shutter to slip.
Misalignment from age or installation. Older shutters, or those poorly fitted, can gradually slip out of square. Over months, the top and bottom guides drift apart, and eventually the shutter loses its seating.
Debris or corrosion in the track. Sand, salt spray residue, or rust particles can accumulate inside the track guides, especially on the Mediterranean coast. This prevents smooth movement and can cause the shutter to jam and then slip off under pressure.
Motor or mechanism failure (motorised shutters). If you have an electric shutter, the motor may have failed, leaving the shutter stuck. When you try to force it, it derails.
Until the locksmith arrives (try to book the same day), your job is simply to prevent the shutter from falling further or collapsing.
If the shutter is partially rolled down and hanging loose: Support it from below with a vertical prop — a length of timber, a sturdy stick, or a rolled-up towel placed under the edge. Make sure the prop bears the weight evenly and doesn't damage the shutter slats.
If the shutter is stuck at an angle: Do not try to straighten it. Leave it as is, and secure it with props on both sides if necessary to prevent it tilting further.
If the shutter is at the top (fully rolled up) and has slipped: Close the window behind it and do not attempt to lower it. Mark the area below with a warning so no one walks underneath. The shutter could fall without warning.
Keep the area clear. Move pets, children, and garden furniture away from directly beneath the shutter. A fallen shutter is heavy and can cause injury.
Do not apply lubricant or spray anything into the track. This will not fix the problem and may make it worse. Only the locksmith should touch the mechanism.
Stop immediately and call a professional if:
- The shutter is motorised and has stopped moving completely. Do not attempt to force the motor or pull the shutter by hand.
- The track is visibly bent, twisted, or has a large dent.
- The shutter has fallen completely out of the track and is hanging by one corner only. This is a fall hazard.
- You hear a grinding or scraping noise when you try to move it. This usually means internal components are broken.
- The shutter is attached to a metal frame that appears to be cracked or separating from the wall.
- There is visible rust or corrosion in the track guides. You cannot clean this yourself safely.
- You are uncomfortable standing on a step or ladder to reach the shutter. Do not climb.
In any of these cases, the safe action is to secure the shutter where it is and wait for the locksmith.
The locksmith will first inspect the shutter and track to find where it has slipped and why. They will check both the left and right guides, the track, and any mounting brackets for damage or wear.
If the problem is simply misalignment (the shutter is still intact but has shifted sideways), the locksmith will carefully lift or lower the shutter — sometimes with a helper — and guide it back into the track guides. They will then test it several times in both directions to ensure it runs smoothly. This usually takes 20–40 minutes.
If the guides are worn or cracked, they will replace them with new ones, sized to match your shutter. If the track is bent, they may be able to tap it back into shape, or they may need to replace a section of track. More complex repairs can take 1–2 hours.
Once the shutter is back in the track, the locksmith will make fine adjustments to ensure it moves freely without binding. They will check that it opens and closes fully and sits properly when closed. If you have a motorised shutter, they will test the motor to ensure it operates smoothly through the full range.
For motorised shutters, the locksmith may need to reset the motor limits if the derailment caused the motor to lose its position reference. They will explain any settings you need to know.
The locksmith will hand you a brief report (informal or formal, depending on their practice) confirming what was repaired and any advice for future maintenance — usually, keeping the track clean and checking the guides periodically.
Check your shutter guides once a month. Open and close the shutter slowly and listen for any grinding, rubbing, or unusual sounds. If movement becomes jerky, contact a locksmith before it becomes worse.
Keep the track clean. Use a soft brush or dry cloth to remove dust and debris from the top of the shutter and from the visible parts of the track. On the coast, do this more often because salt spray and sand accumulate faster.
Avoid forcing the shutter. If it sticks or binds, stop and investigate rather than pushing harder. Call a locksmith if it doesn't move smoothly.
Protect the shutter from impact. Do not lean ladders or tools against it. Warn family and guests not to slam doors or bang objects against the shutter frame.
Have motorised shutters serviced annually. If your shutter has a motor, ask the locksmith for a yearly check-up, especially if you live on the coast or in an area with harsh weather.
If your shutter has fallen off its runners, do not attempt to force it back into place. Secure it where it is, take a photograph, and contact a professional locksmith the same day. Most shutter realignments take under an hour, and a qualified locksmith will have it working safely again without further damage to the guides or track.
