The Project Brief
A measured upgrade, shaped around the property.
White heritage-style sash windows were fitted into an older brick elevation, combining traditional proportions, decorative horns, privacy glazing and modern weather sealing.
What mattered most
- Keep the vertical proportions, glazing bars, horns and white finish appropriate to the older elevation.
- Use privacy glass where the room requires it without breaking the external rhythm of the windows.
- Improve weather sealing and everyday operation while keeping the replacement visually restrained.
Specification Decisions
The details that made the installation work.
Character, privacy, and easier upkeep
Room-specific glazing
Clear glass was used where outlook mattered, with textured privacy glass specified for the more private opening.
Opening-by-opening survey
Each brick reveal was treated as an individual opening so the frame, cill and perimeter finish sit neatly within the existing masonry.
The brief: improve the windows without losing the elevation
The property needed replacement windows that would be easier to use and maintain, but a plain modern casement would have looked wrong against the established brickwork. The answer was a heritage-style vertical slider with the visual cues people expect from a traditional sash.
The completed installation shows why the small choices matter: meeting-rail position, sash horns, glazing-bar spacing and the depth of the white outer frame all contribute to a result that feels settled rather than newly imposed.
Survey decisions shaped the finished appearance
Older openings are rarely identical. The survey therefore needed to account for the brick reveals, existing cills and the relationship between adjacent windows before manufacturing sizes were confirmed.
One opening also required privacy glazing. Specifying that at survey stage allowed the textured unit to retain the same glazing-bar layout as the clear windows, keeping the outside elevation visually consistent.
- White heritage-style vertical sliding frames.
- Decorative horns and applied glazing bars.
- Clear and textured glazing selected by room.
- Perimeter finishing coordinated with the existing brick reveals and cills.
A quieter visual upgrade with modern practical benefits
The finished windows give the elevation a clean, consistent appearance while retaining the vertical emphasis of the original sash openings. Modern balances, seals and glazing make the units simpler to operate and maintain than the older windows they replaced.
Rather than trying to make the property look newly renovated, the installation succeeds by looking appropriate to the house. That is the key lesson for similar sash-window projects in Kingston and neighbouring period-home areas.
