Wooden Sash Window Installers

Sash windows are a distinctive feature of many period properties and form an important part of British architectural history. They became widespread from the late 17th century and are commonly associated with Georgian, Regency and Victorian properties.

The word "sash" refers to a frame that holds the glazing. A traditional sliding sash window usually consists of two sashes that slide vertically, with one positioned in front of the other. Traditional designs use counterweights connected by sash cords and concealed within the window frame, while some modern sash windows use alternative mechanisms.

Traditional sash windows often feature several smaller panes separated by glazing bars. The arrangement can vary according to the architectural period. Six-over-six sash windows, for example, are commonly associated with Georgian properties, while larger panes became more common during the Victorian period as glass manufacturing developed.

When replacing sash windows in a period property, consider the age and architectural style of the building. Designs include Georgian, Regency, Victorian, Gothic Revival, Venetian and Queen Anne Revival styles.

Timber Versus uPVC Sash Windows

If your property is listed or located within a conservation area, there may be restrictions on replacing original sash windows or changing their materials and appearance. Check with your local planning authority before carrying out work where restrictions may apply.

Existing timber sash windows can sometimes be repaired, draught-proofed or restored rather than completely replaced. Where the existing windows cannot be repaired, replacement timber sash windows can be manufactured to replicate traditional styles and detailing.

Wooden Sash Windows Pros & Cons

Timber sash windows can be painted or stained in a wide range of finishes, making it possible to alter their appearance over time. Individual sections of timber may also be repairable if deterioration occurs.

Timber frames require regular maintenance to protect them from moisture and weathering. Without suitable maintenance, problems such as peeling finishes, swelling, warping and rot can develop. The environmental impact of timber windows will depend on factors such as the source of the timber, manufacturing, glazing, maintenance and lifespan.

Fitting Wooden Sash Windows Cost

Replacement sash window prices vary depending on the manufacturer, window size, glazing specification, timber and design. Timber sash windows are generally more expensive than comparable uPVC models, although the appearance or planning requirements of some period properties may make timber more suitable.

Complete replacement may not always be necessary. Repairing or restoring an existing timber sash window may cost around £100-£1,000, depending on its condition and the work required.

A replacement timber sash window may cost around £550-£1,200+. To get a price for repairing or replacing sash windows, click the "post your job" button on this page to compare quotes from local joiners and wooden sash window installers.

Choosing a Carpenter or Wooden Sash Window Installer

When choosing a carpenter or installer to fit, repair or replace wooden sash windows, check that suitable insurance is in place and ask about any relevant training or qualifications. You can also ask to see examples of previous sash window projects and check customer feedback where available.

Obtain written quotes from several carpenters or sash window installers before making a decision. To make the quotes easier to compare, ask each tradesperson to quote for the same work, materials and specification.

Price is one factor to consider, but you should also compare what is included in the quotation, the proposed materials, previous work, timescales and any guarantees offered. This can help you choose an installer and quote that suit your project.
