This is very common with old properties and its normally historical movement , you cannot just re-point the area as the crack will re-appear. So its important that you use some helical bar to crack stitch the vertical crack . This is used by injecting resin and then the bar vertically with a space of 450mm between each bar . You then re-point over the area and you will not see the bar or resin and the area will not move again. Its a good idea to get this done sooner rather than later as its quite normal for water to penetrate inside with this kind of problem. Hope this helps.
