What “shutter” means here
In Indian window terminology the shutter is the moving leaf of the window — the sash. This page is about repairing that moving part: the hinges, stays, rollers, locks and the sash frame itself.
If you are looking for decorative shutter panels and styles rather than repair, that is designer window shutters.
The four things that go wrong
1. The sash has dropped
Hinges wear, or their fixings work loose in the profile, and the sash stops hanging square. It shows up as the closing edge catching the frame, a growing gap at the top corner, and a window that needs a lift to close.
The repair is to lift the sash back into alignment and reset or replace the hinges. What you should not do is plane the frame to accept the dropped sash — that makes the fault permanent and opens a gap when the hinges are eventually fixed.
2. Rollers or tracks have worn
On sliding shutters, rollers flat-spot and tracks collect grit. The sash becomes heavy to move, sometimes jumping the track. Rollers are replaceable; tracks can usually be cleaned and, where worn, re-capped. See top sliding windows for the slider-specific detail.
3. Stays, locks and handles have failed
Friction stays lose their grip so the sash swings in wind. Multi-point gearboxes wear so the handle turns without locking. Both are wear items with a finite life, and both affect sealing as well as security — the locking cams are what pull the sash onto its gasket.
We fit replacement hardware matched to the system rather than generic parts that almost fit.
4. The sash frame itself has failed
Timber sashes rot at the bottom rail first, where water sits. uPVC sashes can have a welded corner open if the section was under-reinforced for its span. Aluminium sashes can corrode at cut edges.
Timber is usually repairable: cut out the rot, splice in sound material, re-wedge the joints, treat and refinish. A uPVC corner that has opened normally means the sash is replaced, though the frame stays.
Rattling, draughts and noise
These three complaints have one cause more often than not: the sash is not being pulled tight against its gasket. Either the locking points are out of adjustment or the gasket has hardened and no longer compresses.
It is worth fixing for reasons beyond the noise — an uncompressed gasket is also letting in dust and road noise, and letting out the cool air you are paying for. Window sealing covers that side in detail.
What we do and do not recommend
We will repair a sash wherever the frame is sound, because it is a fraction of the cost of a replacement window and the existing frame usually has years left.
We will tell you to replace when the frame has moved permanently, when a timber sash has rot through the joints rather than in one rail, or when the profile is obsolete and no hardware is available for it. That last one is more common than people expect with older imported systems.
Send a photo of the sash closed and the gap at the top and bottom corners, and tell us what it does. That is normally enough to diagnose a drop before we arrive.
