Wooden casement windows

REPLACEMENT CASEMENT WINDOWS

We manufacture and install replacement wooden windows across London and the South. We also provide a supply only service nationwide.

Which? Trusted Trader

All our replacement timber casement windows are manufactured in our workshops in Berkshire. Depending on your requirements, we can replicate many different design configurations for wooden casement windows. We also have a Classic Range which covers most period design requirements.

Timber casement window styles

We can manufacture and install a wide range of wooden casement window styles to suit your period property.

Timber flush casement windows are a more traditional design compared to stormproof 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 and soundproofing.

We can manufacture casement windows to suit a range of period properties, including Edwardian, Victorian and Georgian homes.

Established in 1994, we have 30 years experience working in Conservation Areas and listed buildings 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.

Where We Install Casement Windows

We offer an installation service for new timber windows in the following counties:

London, Berkshire, Hampshire, Surrey, Oxfordshire, Hertfordshire, Buckinghamshire, Wiltshire, Essex, Kent, West Sussex, East Sussex, Bedfordshire, as well as parts of Gloucestershire.

If your property outside our installation area, or if you already have a company to install the windows for you, we also offer a supply only service for new joinery across Great Britain.

We offer double glazing as standard to improve energy efficiency. However, for listed buildings we can also manufacture single glazed casement windows (or heritage double glazing) when required.

Double Glazed Timber Windows

Unsure what type of windows you have? Sash windows slide up and/or down to open, whereas casement windows open on hinges, like a door.
