On 26 Sep 2003 09:46:03 -0700, a particular chimpanzee named
(David) randomly hit the keyboard and
produced:

"Slight bulging of brickwork was noted above the kitchen window frame.
Whilst the movement is considered to be historic, pinning back the
brickwork should be undertaken"

Would it just involve hacking out the damaged area and replacing it?

Probably not even that. If it's a small area and out of plumb by no
more than a third of its thickness it should be stable and not need
any immediate action. Otherwise a tie rod can be drilled through the
wall into the floor joists or a cross wall.
