Modern uPVC sash windows

uPVC sash windows keep the vertical sliding action and proportions of a traditional sash while removing the painting, rattling and draughts that come with old timber. Run-through horns, slim meeting rails and period colours help the window sit comfortably on older elevations.

Both sashes slide, and on most designs both tilt inwards so the outside glass can be cleaned from indoors — a real advantage on upper floors. Our guide to sliding sash windows explained covers the mechanics in more detail.

Sash windows across South Wales

We fit sash windows in Cardiff, Newport and across South Wales, where sliding sashes suit the Victorian and Edwardian terraces of the cities and valleys towns, as well as period homes in Bristol and Bath. The right specification depends on the street: some areas have conservation controls that shape what can be fitted, so check with the local planning authority where that applies.

For local detail, see our pages on windows and doors across Bristol, Bath and North Somerset and windows and doors across Bristol, Bath and North Somerset. Where a property is listed or in a conservation area, our guide to conservation areas and listed building glazing explains the questions to ask first.

Replacing timber sash windows

Sash window replacement usually means removing the old box frame and sashes and fitting a complete new unit into the opening. The survey checks the condition of the surrounding reveals and lintels, measures each opening individually — period openings are rarely identical — and records the details that matter to the look, such as horn shapes and glazing bars.

If you are weighing up materials, the guide to timber vs uPVC sash windows compares the two honestly. Fairway Window Systems Ltd provides a free home survey and a written quote, and we beat any like-for-like quote.
