Damp floorboards next to concrete floor

[SALL2009]

I have removed the carpet from this room and the edge of the floorboards that meets concrete floor (old terracotta tiles under the lino) has signs of water.



I went outside and the wall doesn't look very healthy.



Could this be were the surface water is entering the building and then flowing through the concrete floor.

What should be a fix? Could repointing the wall and filling holes in the floor be the answer?

I am not sure if it’s the answer but it would be a good place to start. Hopefully the floorboards will then dry giving you a good indication of the external work helped
