Sash Window Repair for London's Period Properties
GGeorgian Properties (1714-1830)
Georgian sash windows typically feature six-over-six or eight-over-eight pane configurations with slender glazing bars. Original pulleys, weights, and hand-blown glass are common. These windows were designed for natural ventilation and their proportions are integral to the building's character.
VVictorian Properties (1837-1901)
Victorian sashes evolved to larger panes - often two-over-two or one-over-one designs as glass manufacturing improved. Bay windows became popular, along with decorative horns on the meeting rails. Many feature original crown glass with characteristic imperfections.
EEdwardian Properties (1901-1910)
Edwardian windows typically have larger single panes in the lower sash with smaller decorative panes above, sometimes with coloured glass margins. Casement windows also became fashionable. The joinery is often more substantial than Victorian examples.
