Story
The early 14th century East Window is the oldest in Devon except for one or two windows in Exeter Cathedral. The window contains panels of reordered 14th and 15th century painted fragments with 19th century additions and two remarkable donor portraits of Sir William de Ferrers and his wife Matilda, who extended the church in c.1332.
A specialist company asked to survey the window reported as follows:
The window is structurally stable however poorly supported on the current saddle bars which are rusty and have damaged the masonry. Replacement of the ferrous bars with 316 marine grade stainless steel would prevent further expansion related damage to the jambs and mullions.
The medieval glass exhibits surface corrosion on both the interior and exterior faces with areas of deep pitting and surface loss. There is some associated deterioration of the glass paint which should be considered very fragile, but the overall appearance and legibility of the detail remains fairly good.
The window is dirty and hygroscopic crusts and algae are obscuring some of the figures, especially in the tracery. The presence of algae indicates that the window and its immediate environment is regularly wet and for prolonged periods of time, therefore careful cleaning, removal of microbiological growth and improved moisture management at the perimeters and sills is recommended. In order to achieve this safely, the figurative panels and tracery should ideally be removed and cleaned under a microscope.
Given the extent of deterioration found and the ongoing nature of the mechanical and atmospheric damage related to its current position within the church, we strongly recommend the installation of an internally ventilated protective glazing system (EPG). This window contains notable examples of medieval painted glass which have historical and religious significance as well as outstanding artistic merit.

Following the assessment of the window it has been removed and work has begun. This is an expensive project, but needed if the window is to survive for future generations, so donations would be welcomed.
The window will be rededicated by Bishop James at our morning service on the 29th November at 10am.
