    Can I follow on this thread with a similiar issue,
    Our back door has some dampness at the reveal. This is in the kitchen.
    How can I resolve this issue?
    Is it due the warm humid kitchen hitting the cold wall, and maybe the wall is not insulated enough.
    So condensation is building up,
    Or is it a badly installed door?

    So right beside the part of the way that exhibits water ingress, is a pipe(sewage?) pipe running down into the ground. I'm going to take a guess and say there is a bathroom directly above the problem area?

    To me, from the picture that's not "damp", that's just plain old water ingress coming through the brick. Again guessing, I'd say its running down the inside of the cavity block. If it was at the bottom soaking up the wall it wouldn't be so direct to the area, same coming in from outside. So I'd start above where that is, looking at water sources. A bathroom would be the obvious source, probably something touching the outside wall or going through it, roof/windows above it next.
