Grinding, squealing, rattling or banging — each noise points at a different fault, and none of them get better on their own. Here's what your shutter is telling you and how urgent it is.
Why It Matters
Shutters don't get loud for no reason. Noise means metal is moving against something it shouldn't — a dry bearing, a corroded guide, a curtain sitting out of line, or a spring losing its tension. Every cycle after that point makes the wear worse and drags the motor harder.
The businesses that ring us about a noise pay for a service visit. The ones that wait pay for an emergency callout, a new motor and a day of being shut. It is genuinely one of the cheapest interventions available on a commercial shutter.
Worn barrel bearings or debris in the guides. Get it looked at within days, not months.
Dry guides or barrel. Cheapest fix there is, and it stops the wear that follows.
Loose fixings, worn end locks or slat play. Annoying now, sloppy alignment later.
Possible spring failure. Stop using the shutter and call an engineer straight away.

Putting It Right
A proper diagnosis of where the noise is coming from, then the repair — not a squirt of lubricant and a hopeful goodbye.
Guides cleaned of debris and corrosion, correctly lubricated, and the curtain checked for alignment through a full cycle.
Worn barrel bearings replaced and the barrel checked for run-out — the usual source of a grinding shutter.
Counterbalance springs inspected, re-tensioned or replaced by engineers equipped to do it safely.
A sharp bang followed by a heavy or unresponsive shutter usually means a snapped spring. Stop using it and ring 07492 737 695 — that one is not safe to keep cycling.
