uPVC vertical sliding sash windows Surrey & South West London

As a Preferred Installer for the Bygone collection range of bespoke PVCu vertical sliding windows, we can install replacements which closely replicate traditional timber designs.

It’s hard to believe that these sash windows are constructed from uPVC, as they have such superb detailing that it is almost impossible to tell them apart from wooden sash windows.

Advantages of uPVC sliding sash windows

Featuring all the advantages of modern technology – no timber to rot, shrink or swell; no broken sash cords; no draughty or sticking sashes. With the ease of cleaning, superb insulation and great longevity, they are extremely cost-effective.

Our standard grained, wood effect finish is available in either white or cream. Additional colours can be etched into the surface creating a long-lasting bonded paint finish.
