Bricks that are below the damp coarse,(normally door sill height) are prone to frost damage and blowing as these are in a constant damp, also In older properties where there is displaced pointing and perished bricks this can hold damp on walls, which inevitably will cause further damage externally and internally,

we can replace damaged bricks with like for like bricks and match the colour of mortar to match, this will hide any evidence of repairs.
