Broken or Loose Shutter Louvres: Causes, Repairs and Costs
Loose, stiff and broken louvres are three different faults with three different repairs. Identifying which one you have tells you what the work involves, whether new parts are needed and roughly what it will cost. You do not need to take anything apart to find out: the pattern of the fault usually gives it away.
Quick answer
A drooping louvre needs its grip restored, a louvre that no longer turns with its neighbours needs reattaching to the tilt rod, and a cracked or snapped louvre needs a compatible replacement. A replacement louvre averages about £25 and a tilt-rod repair about £50, including VAT, parts and labour with no separate call-out charge. Avoid forcing stiff louvres while you wait.
Key takeaways
- When every louvre in a panel droops, look at the grip across the panel; one drooping louvre points to its own ends.
- A louvre turning out of step with the rest has usually come away from its tilt rod and may only need reattaching.
- Some light between closed louvres is normal, but a louvre that sits out of line or will not close is a fault.
What is the difference between a loose, stiff and broken louvre?
Each louvre is held at both ends where it meets the upright side of the panel, and the grip at those ends lets it stay at the angle you choose. A loose louvre has lost some of that grip, so it drops back, flaps when the window is open or will not hold any angle.
A stiff louvre resists turning, sticks partway or needs both hands. A louvre that turns on its own, out of step with the rest, has usually come away from the bar or mechanism that links the louvres together. A broken louvre is damaged itself, with a crack along its length, a snapped end or a split where it meets the panel.
Some light between closed louvres is not a fault. The British Blind and Shutter Association notes that light will come through where louvres meet and at the edges of the panels, and that some louvres may close tighter than others. A louvre that sits visibly out of line, or will not close while the others do, is a fault.
Louvre faults at a glance
Which louvre fault do you have?
| What you notice | Likely cause | What the repair involves |
|---|---|---|
| Every louvre in a panel droops or will not hold an angle | The grip across the panel has worn or loosened | Restoring the grip, quoted after assessment |
| One louvre droops on its own | Wear where that louvre meets the panel | Repairing or replacing the worn part at that louvre |
| One louvre turns out of step with the rest | It has come away from the tilt rod or linking system | Reattaching the louvre, if it is undamaged |
| Several louvres stop moving together | The tilt rod has broken or come loose | Tilt-rod fix or replacement, about £50 |
| A louvre is cracked, split or snapped | Damage to the louvre itself | Compatible replacement louvre, about £25 |
| Louvres are stiff or hard to turn | Held too firmly, paint or dirt at the ends, or moisture | Easing or adjusting the louvres after the cause is checked |
| Louvres are swollen, warped or discoloured | Water damage | Replacement, not repair |

Why do louvres droop or stop moving together?
Louvres droop when the grip at their ends wears or loosens, and they stop moving together when one comes away from the tilt rod or linking system. Everyday use gradually wears that grip, and the British Blind and Shutter Association notes that timber absorbing and losing moisture over time may cause slight warping or twisting, which can change how a louvre sits and turns.
Look at the pattern. When every louvre in a panel droops together, the grip across the whole panel is the likely cause, and an adjustment may restore it without new parts. When one louvre droops on its own, the problem is more likely at that louvre's own ends, and the worn part may need replacing.
The association describes three ways of linking louvres: a visible tilt bar on the front of the panel, a hidden tilt system at the back, or a concealed mechanism inside the upright side of the panel. On a visible tilt rod, each louvre is attached by a small fixing. If one comes away, that louvre stops following the others; if the rod breaks or comes loose, several louvres stop together. Shutters with a split tilt rod or a midrail are made so the upper and lower louvres move independently, so separate sections are not always a fault.
Do not wedge, tape or glue a drooping louvre, and do not pull harder on a loose rod or force louvres back into line. Tape and glue can mark the finish, and force can break the fixings on louvres that still work. If the louvre itself is undamaged, reattaching it may be all that is needed.
Why are some louvres stiff or hard to turn?
A stiff louvre is usually held too firmly, rubbing against its neighbour or the frame, or caught by paint or dirt built up at its ends. Notice whether the stiffness started after decorating, after new windows were fitted or after a spell of condensation.
Moisture is a frequent reason in kitchens and bathrooms. The British Blind and Shutter Association advises that, apart from products designed for humid rooms, shutters should be kept dry, with condensation and water removed using a dry cloth to prevent damage.
Louvres that have swollen, warped or discoloured after getting wet are replaced rather than repaired, because water-damaged material needs replacement, not repair. Do not force a stiff louvre: forcing it can snap the louvre or its fixings, which turns an adjustment into a replacement.
Can a cracked or snapped louvre be replaced on its own?
Yes, when the surrounding panel is sound and a compatible louvre is available. The replacement has to match the existing louvre's width, length, shape and material, and suit the way the louvres in that panel are held and linked.
A replacement louvre averages about £25, including VAT, the compatible part and labour, with no separate call-out or travel charge. A new louvre can look slightly different beside an older finish, so we explain any likely difference before the work goes ahead rather than promise an identical result. Keep any pieces that have come away, because they show the original size and shape.
A louvre that broke because the side of the panel has split, or because the panel took a knock, needs the panel checked too: a new louvre cannot hold securely in damaged material. When many louvres are damaged or compatible parts cannot be found, replacing them one at a time may not give a lasting result. Older sets with several worn parts may suit restoration, our repair-or-replace guide explains how we compare the options, and Shutters Design supplies completely new made-to-measure shutters when a new set is the better route.
What does a louvre repair cost, and what should you send first?
Our indicative average prices include VAT, the stated parts and labour, with no separate call-out or travel charge: about £25 for a replacement louvre, about £50 for a tilt-rod fix or replacement, and about £25 to realign a dropped panel. Restoring the grip across a panel and reattaching a louvre are quoted after we have seen the shutter.
Several faults on one set are priced as one job, and we confirm the work and price before starting. We complete approximately 90% of repairs in one on-site visit; some jobs need a compatible part to be ordered or a return visit, and we say so before booking. Our plantation shutter repair cost guide explains how quotes are built.
You do not need to name the faulty part or open the shutter up. Send a photograph of the whole shutter and a close-up of the affected louvres, and mention the room. A panel that has dropped, rubs on the frame or will not close properly has a hinge or alignment problem rather than a louvre fault, which our plantation shutter repair guide covers.
Before you book
What to check and photograph
- Whether one louvre or a whole panel is affected.
- Whether the louvres droop, stick, turn out of step or are cracked.
- Whether the panel itself has dropped or rubs on the frame.
- A photograph of the whole shutter and a close-up of the affected louvres.
- Which room the shutter is in, especially a kitchen or bathroom.
- Any pieces that have come away, kept somewhere safe.
