Project: Wholesale Window Replacement in 18th Century Stone House

This Rutland project was substantial—a complete window replacement across three floors of a Georgian country house that hadn’t been touched since the 1970s.

The existing windows were a mix of rotting softwood and badly-fitted aluminium (someone’s idea of “modernisation” in 1978). The clients wanted everything back to how it should be: proper Georgian sash windows with slim bars, correct proportions, and none of that chunky modern glazing.

We manufactured the lot in meranti hardwood—more stable than softwood for these large countryside windows, and better value than oak for a project this size. Each sash window got authentic 18mm glazing bars arranged in 6-over-6 pane configurations for the principal rooms, 2-over-2 for the upper floor bedrooms.

Installation took three weeks working room by room so the house stayed weathertight. The stone reveals were irregular (18th century masons didn’t use spirit levels), which meant every window needed individual adjustment on site.

Final touch: the clients chose a custom mixed grey paint that matches the Rutland limestone perfectly. Drive past and you’d assume these windows have been there 250 years. Check the energy performance certificate and you’ll see they’re better than most new builds.
