Sash windows in Chiswick

Chiswick is a diverse area with a range of housing options to suit different lifestyles. Nearly every property in Chiswick is well-suited to sash windows.

Georgian and Victorian terraced houses: Chiswick has a number of historic terraced houses, many of which date back to the 19th century. These properties are typically well-proportioned, with high ceilings and period features such as fireplaces and sash windows.

Edwardian and inter-war, semi-detached houses: Many of the semi-detached houses in Chiswick were built during the early 20th century and feature spacious layouts and original features such as stained-glass windows and ornate tiles.

New-build developments: In recent years, Chiswick has seen a number of new residential developments, including modern flats and apartments as well as luxury townhouses.

If you want a classic example of period sash windows, then look no further than the famous Hogarth’s House, the former home of the famous English artist and satirist William Hogarth. Built in the early 18th century, the house has been restored to its original Georgian splendour, complete with period furnishings and artwork, including several stunning sash windows, installed by SashWise.

Should you repair/refurbish your sash windows or simply replace them?

There are several compelling reasons to refurbish sash windows rather than replace them. 

  1. Historical and architectural value: Sash windows are often found in older and historically significant buildings, contributing to their charm and character.  In this area we are lucky to have great numbers of heritage properties. Residents are keen to maximise the historical and heritage value of their homes, which is why we recommend refurbishing your windows to help preserve the original architectural features and maintain the authenticity of the property. By refurbishing sash windows, you can retain the historical value of your house, while enhancing its overall aesthetic appeal.

  2. Cost-effectiveness: Refurbishing sash windows can be a cost-effective alternative to complete window replacement. Replacing windows entirely can be expensive, especially when dealing with multiple windows. Refurbishing sash windows involves repairing and restoring the existing frames, replacing damaged components, and improving their functionality. This approach can save a significant amount of money compared to installing brand new windows.

  3. Energy efficiency and insulation: Older sash windows may have gaps, cracks, or inefficient glazing, which can result in drafts and heat loss. By refurbishing these windows, you can address any issues and improve the energy efficiency. Upgrading from single to double glazing can significantly enhance insulation, reduce heat transfer, and contribute to lower energy bills. Additionally, sealing any gaps or cracks and ensuring proper weather-stripping can further improve insulation, making the space more comfortable and reducing your carbon footprint.
