Whenever there is a prolonged period of rain a patch of damp appears at the bottom of an internal wall. It's not huge, maybe 6 inches tall but it used to be half the size it is now (I'm going back a year or so). On the other side of the wall is our conservatory and on this side there are no signs of damp; we've also lifted the carpet and it appears dry underneath but can't get under the conservatory floor as it's tiled. The skirting board appears dry and undamaged.
The house is 1940s.
There is an air brick outside and I'm wondering if that's likely to contribute (see image)? I forgot to draw it but in the bottom left corner is our electricity meter cupboard so it's difficult to see the back of the outside wall if that makes sense, but from what we can see its dry. In summer there is no sign of the damp and during light rain showers it also doesn't appear.
Any ideas?
