Overhaul and Draught Proofing

The benefits of draught proofing include improved insulation, removing rattles and rolls and sound proofing. Modern innovations and products allow Preservation Windows to seal any gaps around your windows and eliminate draughts without altering the appearance of your windows. 

As well as making your home draught free, the Preservation team can carry out a full service of your windows, including replacing the sash cords, replacing any rotten timber or sills and making your windows open smoothly. 

Bespoke Replacement

The other option involves the complete renewal of the windows. All of our windows are custom-made to your requirements by our expert craftsmen at the Preservation workshop based just outside of Glasgow. Each window is manufactured, glazed and painted at our workshop before being delivered to your home to be installed by one of our experienced joiners.
