Heritage replacement windows and glazing are designed to replace windows or individual elements that can no longer be effectively repaired, while remaining sympathetic to the character and architectural style of the property. For period buildings, careful consideration is given to details such as the glass, leadwork, proportions and existing frames.

Common problems include cracked or broken glass, deteriorating leadwork, draughts, leaks, condensation, rotten timber and corrosion to metal frames. Older windows can develop several issues at once, so assessing the complete window is important before deciding on the appropriate repair.

Heritage window design is the process of creating glazing that complements the age, architecture and character of a period property. Rather than using a standard modern window design, details such as the glass, leadwork, proportions and existing frames are considered to achieve an appropriate appearance.

Heritage window repair focuses on fixing damage and deterioration while retaining as much of the existing window as possible. Repairs can involve the glazing, leadwork and frames, with the aim of extending the life of the window while preserving its traditional appearance.

Heritage window restoration involves carefully repairing and improving older windows while retaining as much of their original character and fabric as possible. The aim is to preserve the appearance of the window while addressing issues caused by age, damage or deterioration.

Restoration can address problems including broken or ageing glass, deteriorating leadwork, draughts, condensation, leaks, rotten timber and rusting metal frames. The appropriate solution will depend on the condition and construction of the individual window.

Heritage double glazing typically uses slim insulated glass units that are considerably thinner than standard modern double glazing. This allows them to fit within traditional window frames that would not normally accommodate conventional sealed units. The exact thickness depends on the glazing specification and the requirements of the individual property.

The right glass depends on the age and character of the property. Sherriff offers options including Flotara, which provides a clearer appearance, and Heritane, which has an irregular surface designed to recreate the distinctive character of older historic glass.
