For owners of listed buildings or homes located within sanctuary, the legal structure surrounding window modifications is rigid. Historical home window professionals must be skilled in regional and national preparation policies.

In many jurisdictions, changing original windows with contemporary double glazing is prohibited since it changes the profile and reflection of the building.

Typical Historic Window Styles
Specialists need to be masters of various architectural styles, including:
Sash Windows: Common in Georgian and Victorian architecture, utilizing a system of weights and wheels.Casement Windows: Hinged windows that precede the sash style, typically seen in Tudor or cottage-style residential or commercial properties.Leaded Lights: Small panes of glass held together by lead cames, normal of medieval and Gothic Revival structures.Crittall Windows: Iconic steel-framed windows popular throughout the Art Deco and Modernist movements.Technical Innovations in Restoration
