hmmm as others have already mentioned most sensible answers - so I will just add
we live near a lake and the property is built on reclaimed marshland so a very damp area - we suffered from extreme damp and had double glazing installed but the damp remained. After a year or so we purchased a dehumidifier and left it running on full for a few days - each day or so emptying the full container. After a few weeks the collected water was less - I believe that because the whole house had become damp it took this extra "usage" to dry out the whole home.
Now we switch it on occasionally - no steamed up windows etc
Hope this helps
Just found this link for you - maybe an idea to consider
