What Is A Listed Building?

A listed building is a building that has been placed on one of the four statutory lists maintained by Historic England in England, Cadw in Wales, Historic Environment Scotland in Scotland, and Northern Ireland Environment Agency in Northern Ireland.

If you live in a listed building, it may not be destroyed, extended, or changed in any way without permission from the local planning authority, which typically consults the relevant central government agency, particularly for significant alterations to the more notable listed buildings.

What Is A Sash Window?

The word ‘sash’ refers to a single frame for glazing; a traditional sliding sash window features two sashes that slide up and down. In basic terms, the weight of the glazed panel is usually balanced by a sash weight or counter-weight hidden within a hollow box frame.

This timeless design is commonly found in Georgian and Victorian properties, but can also be seen with variations in late Victorian and Edwardian houses.

Signs Of Poor Sash Windows

Most defects you are likely to find with sash windows will be evident on close visual inspection. Such as,

  • Condensation

  • Failure to open

  • Loss or breaking of the sash cord

  • Loss or deterioration of putty

  • The old paint braking away

However, timber decay is one problem that is less easy to spot. It’s usually possible to restore even the most rundown windows, but when the lifespan inevitable runs out, the window will need to be replaced.
