Sash Window Repair in Puddletown, Dorset

The upstairs bay sash window in this quirky Listed Cottage was made up of five sections, the outer sashes convex and the middle three pairs flat, though the centre top sash had a semi-circular arched head.

Project Details

The main problems were that most of the sash ‘joints’ weren’t joints at all. Adjoining sections of timber were butt-jointed and held together with nails or angle brackets which had mostly rusted away. So the sashes were falling apart.


First task was to dismantle each sash in turn, remove thick, sticky layers of ancient paint and putty before rotten wood could be replaced and new mortice and tenon joints made.

One of the curved sashes is shown in the final stage of repairs after re-assembly with proper, durable joints.
