REPLACEMENT TIMBER SASH WINDOWS

The Sash Window Workshop specialise in the replacement of traditional timber sash windows in period properties.  We offer a supply and fit service across London and the South, with a supply only service nationwide.

The majority of our new timber sash windows are made in Accoya, a sustainably sourced modified wood that comes with a 50 year anti-rot guarantee. We can also make windows in alternative hardwood timbers if you prefer.

Our new windows come fully factory painted (with three coats) in white, as standard.  However, if you would like a specific colour we can also colour match to different paint finishes.

If required, customers can opt for special glazing such as stained glass, obscured glass and bowed glass.  We also offer a range of ironmongery options for your new sash windows.

Timber Box Sash Windows London and Southern England

Did you know that the traditional box sash window has been around since the 17th century? Amazingly the cord and lead weight design remains almost unchanged with spiral hung sash windows being a more modern development.

Victorian timber sash windows are a key architectural feature in a number of areas around London including Kensington, Islington and Hampstead.  Conservationists are keen to retain the heritage features.

At The Sash Window Workshop we are able to ensure that the patterns and designs are precisely copied to comply with any listed building or conservation area requirements for wooden sash windows in London and Southern England.

Energy Efficient Timber Sash Windows

When looking to replace timber sash windows it is important to ensure that the new sash windows are as energy efficient as possible. Did you know that traditional, double hung sash windows can provide excellent ventilation during the summer months.

At The Sash Window Workshop, our new timber windows are manufactured to provide the modern benefits of double glazing, while preserving the character of your home.

If you are unable to install double glazing, due to planning restrictions, we are also able to manufacture replacement single glazed wooden sash windows or use heritage double glazing, which uses a narrow profile meaning that it is more likely to be approved by planners.

If we are installing replacement sash windows in London and the South of England, we will also draught proof the windows on installation, helping to keep your home warm during the winter months.

To view examples of our previous work, view our gallery pages.

In addition to complete new timber sash windows, we can also manufacture and install new sashes into the existing window frames, alongside complete new casement windows and external wooden doors.  If your windows don’t require replacement, we also offer a draught proofing and overhaul service for timber windows.
