Casement Windows in Highgate, London
Every casement windows project we deliver in Highgate starts with a senior surveyor on site — measuring, listening, and specifying to the character of Highgate Village, Highgate West Hill and the wider London area. Side-hung and top-hung casement windows in uPVC, aluminium and flush-casement finishes.
Casement Windows designed around sash-heavy period stock, communal-window agreements and RBKC / Camden conservation planning.
Highgate Village's Georgian core, the Heath-facing streets along Merton Lane and Fitzroy Park, and the substantial Victorian villas across N6 need matched sightlines and painted finishes. We install throughout with drawings prepared for Camden and Haringey planners.
