Looking at insulting my loft somewhere in the near future to use as an office space. Gable end brickwork looks pretty bad, mortar sandy and missing in places. Gable end is also single brick - what would be the best way to insulate and repair this?
Property was built around 1890, end terrace.
Would I be right in thinking i'll need lime mortar to repoint & would this be suitable? - https://www.lime-mortars.co.uk/lime-mor ... cragg/25kg
