New Double Glazed Sash Windows into Existing Frames

If the frames are in good condition, we can replace just the sliding parts of the window, saving you money, minimising disruption, and retaining the heritage of your home. Alternatively we can manufacture and install complete new timber box sash windows including the window frame.

Below is a quick walk through by The Sash Window Workshop on installing new timber sliding sashes into existing window frames:

The materials we use are of the highest quality performance and durability. Customers can choose between timber types, glass specifications, paint finishes and furniture specifications.  The majority of our sash windows are made using AccoyaTM, a sustainably sourced manufactured wood.  View our gallery page for examples of our previous work.

We make the majority of our own double glazed glass units and cut our glass in house. This allows us to maintain the highest standards in both the glazing and the joinery. New complete wooden sash windows are glazed to offer the best in energy efficiency. If required, customers can opt for special glazing such as stained glass, obscured glass and bowed glass.

London sash windows

All our replacement timber windows and doors come fully factory finished.  Our standard paint finish is white semi-gloss inside and outside consisting of base-coat primer / preservative, undercoat and topcoat. Other colours and stains from specialist suppliers are available on request, but there may be an additional charge.

To improve the security and usability of your new timber windows our standard ironmongery range is selected to be high quality, elegant and hard wearing.

Traditional Timber Box Sash Windows London

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, which is why we work closely with them to ensure that the patterns and designs are precisely copied.
