Sash windows

Myth-busting

Wooden sash windows needn’t go in the skip

TALKS AND DISCUSSIONS

Saturday 16 May 2026

Meet specialist heritage conservation carpenter Ross Harris as he explains how wooden sash windows can be economically and effectively repaired.

Ross Harris busts the myth that wooden sash windows are only fit for the skip. He’ll show how old wooden sash windows, often made of high-quality timber, can be repaired, re-corded, re-glazed and preserved and in use for years to come. He’ll talk about the pros and cons of inserting replacement double-glazed panes and the options for secondary glazing and draft proofing as well as specialist adhesives and paints.

A collaboration for  London Craft Week
