Reinstate & Reactivate Sash Windows 1

Reinstate Sash Window

For Over 20 Years We Have Been Reinstating & Reactivating Sash Windows to their original double-hung sliding operation.

Reinstate The Original Box Window Style And Remove Ugly Window Conversions

Reinstating sash windows to their original double hung operation will restore the original charm of your period home.  

Over the years many heritage sash windows have undergone various conversions such as fitting uPVC, aluminium, louver, pivot or casement window sub-frames.  Fortunately the original box frame is often left intact and we can undo the conversion and reinstate them into a fully functioning, single or double glazed sliding sash window.

After removing the existing window conversion we fit a replacement balance system including new pulleys, cords & weights. 

We undertake frame repairs before installing our authentic replica wooden sashes into your existing timber frames. Sashes are supplied paint finished, either single or double glazed.

Bespoke Wooden Replicas

We carefully reproduce a copy of the original sashes using any photos you might have or referencing a neighboring property. By increasing the rebate depth we accommodate a sealed double glazed unit.
