cracks in brick mortar
Couple of things:
- The bond on those brick seems real close, which is certainly prone to step cracks.
- Windows are a common place for step cracks as well, and often they're just a good indicator of where a control joint would have been helpful. Control joints are rare in residential masonry though.
- More than likely, chiseling or grinding the joints out, and then tuckpointing with a tinted Type S mortar will be your best & easiest solution.
