I've just noticed a cracked brick, and wondered if I could just replace it and do some repointing, or could suggest another problem?
The cracked brick appears to have a crack in the mortar moving diagonally up a 3 or 4 bricks to the right. I've included a photo and the brick I'm talking about is 3 bricks up from the left window sill and then 3 in.
My house was built in 1910, and has had its wall ties replaced in the late 70s.
