REPLACEMENT CASEMENT WINDOWS

We manufacture and install replacement wooden windows across London and the South, providing a supply only service nationwide

All our replacement timber casement windows are individually manufactured in our workshops in Berkshire. There are many different design configurations of wooden casement windows that we are proud to be able to replicate depending on your bespoke requirements. We also have a Classic Range which was developed over many years and covers most period design requirements.

Our timber casement window styles

We manufacture and install a range of wooden casement window styles to suit your period property and offer double glazing as standard.  For listed buildings, we can also manufacture single glazed casement windows.

Timber flush casement windows are a more traditional design style of casement window than storm proof casement windows. Flush casement windows sit flush within the frame, creating a flat surface on the outside.

In contrast, stormproof casement windows (sometimes referred to as lipped casement windows) overlap the window frame when closed.

We are also able to replace casement sashes (the moving parts of the timber casement window) if the frames are still in a good condition.

Timber Casement Windows in Period Properties

At The Sash Window Workshop all our replacement timber windows are designed to add charm and character and be in keeping with your home, while providing modern benefits such as double glazing.

We can manufacture casement windows to suit a range of period properties and listed buildings, including EdwardianVictorian and Georgian properties, and have extensive experience working in conservation areas across London and Southern England.

If your windows are in a good condition we can repair the existing window by carrying out our draught proof and overhaul service.
