UPVC Sash Windows

Architecture in large parts of London and the South East of England still features traditional sash windows. Sash windows are a main feature of Georgian, Victorian and Edwardian architecture and therefore a part of British building heritage.

Sash windows in conservation areas invariably have to be made from wood, but in other parts of our rural and urban landscapes it is not a requirement to fit timber framed sash windows when replacement windows are needed.

For any measurements or advise we will travel within the 5 mile radius so do give us a call so we can advise you the best quality windows for your home.

We guarantee your orders will arrive within the 4-5 weeks time and we will provide the best service installation possible.

If your current windows have reached the end of their lifetime and it is not feasible to repair or restore them, or if you are looking to replace your windows completely, contact us for bespoke sash window solutions.

We are specialists in creating new made-to-measure sash windows and casement windows. With the ability to create practically any moulding shape, our services are especially valued by clients in conservation areas, where it is imperative to match a particular window moulding to existing styles. If you choose timber framed sash window replacements in either hardwood or softwood, all our bespoke sash windows are made to measure and adhere strictly to current building regulations.

We are specialists in joinery work that will create beautiful bespoke sash windows no matter what style, shape or size you choose. We can also supply bespoke UPVC sash windows and supply you with new window sills.

We can recreate heritage details such as mouldings or glazing bars that will match your existing windows and finally show your period home to perfection. Sashco can supply bespoke windows that are built to last and are suitable for homes in conservations areas.

If you live in a period home in a conservation area, any sash window refurbishment will have to be carried out by an expert. Sashco can offer quality joinery work that can replace your window sills or carry out repairs to your existing window sills, astragals, sash bottom rails or any other part of your timber sash window that needs attention.

Every sash window consists of a large number of elements that can develop faults through wear and tear. The very first sash windows were introduced in the late 17th century and over the next couple of centuries changes in glass manufacture techniques meant that sash windows changed dramatically in style and design.
