Conservation-Led Timber Window Restoration by Barnsbury Joinery

 

Barnsbury Joinery provides heritage sash window repair in Kennington, London, helping homeowners preserve and restore original timber windows in period and historic properties.

Kennington is known for its Georgian terraces, Victorian townhouses and conservation areas, many of which retain original sash windows. Our work focuses on repairing rather than replacing, maintaining the architectural character while improving performance and longevity.

​

We carry out careful, conservation-led repairs to traditional sash windows, ensuring original features are retained wherever possible.

​

Our services include:
