Every premises. Every shutter type.

We understand that your roller shutters have to do more than just protect your premises. A retail unit may wish to display its wares at night, through security shutters that allow a clear view of the products in the window. An industrial location may wish to discourage intruders with roller shutters that look even harder to break into than they are.
We offer a range of shutter types, from transparent and punched shutters to galvanised and powder-coated roller doors. And our shutter repair London teams are happy to offer advice on the best kinds of shutter for your needs.

Our electric shutter motors are the best in the business: quiet, efficient, and quick. But power failures happen. So our shutter repair London teams install motors and doors that are also equipped with the oldest, most tried-and-tested technology of all. Your new door, or newly-installed motor, will come with a hook-and-winder assembly, which allows manual raising and lowering of the shutters in the event of power cutoff.

As well as shutter repairs, we design, fit and repair secure shop fronts. We fit frameless toughened glass shop fronts. And a range of glass types in aluminium framed frontages.
