A line of damp appeared yesterday on the kitchen ceiling from the wall extending into the middle of the room. Looks like three puddles above, soaking through and linking up. The house is just over two years old (George Wimpey).
My only idea is that there is an air brick outside at ceiling level and we had absolute torrents of rain all day yesterday. The air brick is pretty well adjacent to where the dampness starts at the wall. The dampness has more or less dried out overnight (once the rain stopped).
Is there anything obvious I can do to check whether the air brick is the cause, or what else it is likely to be. And if so what would be the best cause of action to fix it?
Incidentally, I'm not clear why there would be an air brick at ceiling level. It is also adjacent to the cooker, which has an extractor fan but which, as far as I can tell, does not have an vent through the wall from the inside.
thanks for any help/advice you can give
