Two of the limestone jambs to the fireplace were badly deteriorated. One of the stone jambs was repaired with lime mortar, the other with natural stone.
The damage to one stone was minimal so the use of lime mortar repairs allowed minimal intervention to the stonework. Before the lime mortar was applied armatures were fixed to provide a key for the lime mortar. The final coat was applied and the lime mortar was run in-situ to match the existing moulding. A careful selection of sands and stone dusts were used to blend in with the existing stonework colour and texture.
The other stone jamb however, had deteriorated tot he point that there was concern that the stone was not performing its role structurally. A check was carefully chiselled out of the damaged stone to accommodate a newly worked stone matching the existing moulding.
