Most Georgian and Regency (1714 – 1830) buildings are Grade II listed. If your property is listed, please click here for more information.

Buildings constructed during the Victorian and Edwardian periods (1837 – 1910) are generally not listed and in most cases still have the original box sash windows in place. Windows in such properties have very poor thermal and acoustic performance. Whilst we are happy to quote for major restoration and repair in unlisted properties, including the introduction of draught seals, we advise against it. Major overhauls are not cost effective and fail to adequately address thermal loss, acoustic issues (traffic noise etc.) and internal condensation.

Replacement copies true to the original detailing will give significant thermal and acoustic upgrades, yet retain the building’s refined sight lines and intended design features. 

Although replacement windows may be more expensive initially – compared to a major overhaul – the reduced heating costs and the durability of the windows compensate for this adequately over time. Introducing building regulation compliant box sash windows is an investment that increases value and will be recovered in the selling price of the property, unlike uPVC windows, which devalue period buildings.

For period buildings in which plastic or aluminium windows have been installed, we can reintroduce high spec. timber box sash windows appropriate to the age of the building, thereby restoring the original period façade.
