How do we upgrade your sash windows?

We make new timber sashes out of Sapele or Accoya, both of which are incredibly durable. We then fit into the existing boxes that we fully restore.

Replacing the sashes without replacing the boxes is a more cost-effective solution and less disruption than replacing the whole window.

We always take great care to ensure that the new double glazed sashes sympathetically replicate the originals, in terms of style, pane configuration and matching any horn or molding detail. 

On-site our team of window fitters will strip back the sash box frames to wood, they will repair any rot and replace hardwood cills if required.

Then the boxes will be painted to finish coat using The Little Green Company paint. Once the boxes are ready, we will install new pulleys, new lead weights and then fit the new double glazed sashes incorporating a draught-proofing system.

Finally, we provide new security locks and window furniture.

If you are looking to improve the thermal performance of your sash windows and reduce noise pollution then our workshop in West London can make double-glazed timber sashes to fit within your original box sash frame. This is a more cost effective and less disruptive process than replacing the whole of your sash window.

Our skilled craftsmen take great care to replicate the style and detail of your existing sashes so that they maintain the traditional character and architectural identity of your property. The thickness of the double glazed unit that is fitted depends upon the width of your existing sash box. In most cases, a specialist 12mm ‘restoration unit’ is used that encompasses an inert gas within the unit and a pane of low-emissivity glass, which reflects heat back into the room.

All of our new timber double-glazed sashes are finished with a range of traditional sash furniture and installed with the added benefits of our specialist Draught-Proof System.
