Sash windows are a classic and timeless feature of many traditional and modern properties. They are composed of one or more movable sashes that slide vertically or horizontally, held in place by counterweights, cords, and pulleys. Sash windows provide excellent ventilation and insulation, and enhance the visual appeal of any property, whether it is Georgian, Victorian, Edwardian, or contemporary.

However, sash windows can also be prone to wear and tear over time, especially if they are exposed to the elements or lack proper maintenance. Common problems that may affect sash windows include rot, decay, rust, warping, sticking, rattling, drafts, condensation, and noise. These issues not only compromise the performance and aesthetics of the windows but also pose a security and safety risk to the occupants.
