Commercial Window

Improve natural light, control the temperature within your building, and add a professional-looking finish to your premises with our commercial windows.

With more than 60 years’ combined experience in installing, repairing and maintaining windows across the capital, you can rely on the expert team here at Sureclose to take care of all your commercial maintenance needs in London and the surrounding areas.

Working to increase the lifespan of your glazing wherever possible, we can accommodate every type of window, from old Crittall structures to modern tilt and turn windows, high-level windows, and low-level windows. Our staff can also source and install new windows and window operating equipment where it makes practical and economic sense to do so.

We have a vast network of suppliers, and we pride ourselves on having access to spare window parts that are difficult to find.

Secondary glazing

Reduce heat transfer across your building and improve your internal acoustics by adding a slim additional layer to your windows.

Popular styles, materials and finishes

Our product range is second to none. Sliding sash windows, timber windows, uPVC windows, tilt and turn windows – you name it, we can install it or fix it!

Window operating systems

Manual remote opening systems, often called Teleflex winders, operate high-level windows using a remote handle at a lower level. We install and maintain various brands of these systems.

Finishing touches
