Since purchase in 2016, various damp problems have manifested in numerous locations, several of which focus upon the centrally located chimney stack. Despite multiple attempts to resolve the problem; chimney and roof repairs, clearing and repairs to gutters, the symptoms have persisted.

Traditional methods such as lime plastering are often the preserve of buildings deemed to be of historical importance, yet it seems to have been forgotten that more modest properties such as the ubiquitous Victorian terrace were also built with solid walls, lime plaster and a need to ‘breathe’. The designers and craftsmen who built them were creating a carefully balanced internal climate to ensure occupant comfort, avoidance of damp & protection of the fabric of the building and its structural integrity.
