What we do

Timber Sash and case Windows 


We’re qualified and experienced joiners specialising in the renovation of traditional sash and case timber windows. We’re based in Glasgow and most of our work comes from the elegant Victorian and Edwardian housing stock of that city - but we also work in the rest of Scotland, on buildings of any age, and in commercial and public property as well as residential houses and flats.


We’re experts in timber sash and windows and we can handle anything and everything about them. A typical renovation project would involve repairing, repainting and draught proofing your sash windows so they look and work like new, at a surprisingly affordable price. We’re also happy to carry out smaller repairs, for example fixing or replacing weather damaged windowsills, or repairs to leaded or stained glass.


We’ve done lots of work in conservation areas, on listed buildings, on grant aided projects and with heritage organisations. This means we can anticipate special requirements and offer informed advice to homeowners, architects and project managers.


Of course you may want to replace old sash windows with new double glazed units. We make and install beautiful new timber sash and case windows to suit the original style of your home perfectly. These are acceptable in many conservation areas and listed buildings - and they’re always an attractive alternative to modern PVCu frames, wherever you live.


Lastly, although windows are our first love, we can undertake general joinery work too. So if you’d like us to quote for decking, doors, wooden flooring or alcove work, please do get in touch.
