Timber Windows


This was one of our favourite installations in recent years. A spacious house in the country alongside a tumbling river and surrounded by woodland. It was beautifully sunny on this day but on our first visit, in the depths of winter, the house was so cold that you could see your breath in some rooms! The multiple large sliding sash windows were just leaking heat on every elevation.

Our job was to replace the windows with energy efficient double-glazed timber sash windows without changing the look of the house at all. That meant, tucking the windows behind the stonework by the same amount as before, finishing the insides with colour-matched moulded timber trims and pointing the outside with a lime-rich mortar to blend in with the rest of the stonework.

We installed our Traditional Sash window throughout, painted in Gardenia and with quality brass fasteners and hook lifts. The results speak for themselves.
