Replace brick below damp course.

Looking at buying this property but a little worried about a part of a single height extension which has blown brickwork. Concrete path up against may be the issue and led to water/  frost damage. No damage or crack elsewhere in any of the house or above this area. Its been owned by the same person since 1960s and been let go over the last few years.
