Sash window restoration in Belfast.
Conservation-grade restoration, repair and bespoke manufacture of timber sash and casement windows across Belfast and Northern Ireland. Restored where they can be saved, made new where they cannot.
Heritage window specialists
Sash Restoration Belfast restores, repairs and makes timber sash and casement windows for period properties, listed buildings and conservation areas across Belfast, County Antrim, County Down and the rest of Northern Ireland.
Restoration and manufacture happen under one roof: original sashes repaired, new ones made to match. Our joiners bring over 25 years of combined experience and work to conservation standard.
We restore before we replace. Windows that other firms condemn can often be fully restored, which costs less than replacement and keeps the original joinery and glass.
Our purpose is to help preserve historic buildings and heritage architecture wherever possible. Where restoration is not possible, we manufacture heritage-grade replacements using traditional methods in our Belfast studio.
