New Bespoke Joinery

Whether you require a complete new box sash or sashes to fit your existing boxes, Envirosash can manufacture and fit beautiful timber bespoke joinery to suit your individual requirements.

Our replacement bespoke joinery can be made to look in keeping with your existing windows by replicating their often unique profiles and features.

Our bespoke joinery is hand made from a range of different timbers using traditional construction methods, such as wedged mortice and tenon joints. We mainly use Accoya, which is a sustainably sourced wood that goes through an acetylation process creating an extremely durable timber. 

This means that all of our sliding sash windows, casement windows and doors are built to last.


Each new timber window that we produce is individually customised with your choice of options...
