Noticed a couple of cracks opening up through the middle of two individual stones on the external wall of our house. One is on the external chimney stack the other not.
Just wanted to know how concerned I should be with this type of crack? I don’t know for sure when they opened up or if they were already there when we moved in 1 year ago.
there are quite a few cracks through the mortar joints elsewhere but these seemed more concerning. Any thoughts appreciated.
