Section of damp on exterior redbrick

phunkadelic

Hi, posting this a person with very little DIY experience, but spotted a section on the outside of the house that is noticeably damp early in the morning after the dew, then gradually dries off during the day. It goes across redbrick and also the concrete on the door frame.
There is a corresponding patch of damp on the interior at that same place.

Drainage seems ok on that wall, no loose pipes or drains. It seems to come across from the small blue boundary wall, but that might be unrelated.

Anyone got any ideas on whether it would be handy to fix, or some kind of process of elimination?

Pls post some internal pictures.
Does it dry inside during the day

Inside is more just showing through the paint. Can't feel the damp but it is visible

What's the other side of that wall. Neighbouring one. Water appears to be travelling horizontally

I'll check that. Not that easy without being spotted!

could there be vent from neighbours boiler on other side of blue wall?
maybe a leak within the wall travelling along that header course?

Is there any possibility of a water pipe in the wall? Unlikely, I know, just a vague possibility

I cant see anything on the far side of the blue wall at all. And no pipes going through the wall either

Can you take a photo from further back of the entire rear elevation please?

As listermint and others suggested - it might be helpful to find out what is behind the blue wall.

Perhaps use a mirror on a stick to check it out or try to look over the wall?
