Most of the ground floor is wooden floor boards but there are two tiled
floors where I guess it seems to be a solid floor underneath.

I live towards the bottom of a steep hill. Could it be water underneath
flowing downward?


If this is ground floor and the damp doesn't affect the external walls,
you have to be looking at some kind of rising damp or a leak. Either way
the damp should be worse at the bottom and not go any higher than 1
metre. Is this a solid floor?
