Hi all,

Can anyone explain what kind of damp this is and what might be causing
it? There is nothing amiss or damaged on the outside of the building that
could account for it so I'm at a complete loss as to what the underlying

Thanks.



Getting in at the top of the frame (side or top surface) and dripping
down the voids in the frame. Building up at the bottom. Look for
pinholes in the sealant around the top.
