I have a damp patch on the bedroom wall up near the ceiling and one half way down.

Ihave been up in the loft and the chimney is dry all round, their are cowl's on the chimney pots to help stop the rain entering.

How can the damp show through such a long way down from the chimney?

Thanks

Is there a vent in the chimney breast in the bedroom ?

Thanks for your reply, yes their is a vent in the chimney.
