The point about gutters is really important. We have a Victorian farmhouse
with a few damp problems. Fixing the gutters, new roof and lead flashing
sorted it and we did not carry out the remedial damp course work identified
during the survey. Doing sensible things like letting the property breathe
can also help - for example mildew can form on the back of fitted carpets on
tiled floors due to very slight permeability so we enjoy the tiles instead.

Many older buildings have stone drains, formed by putting flat stones on
edge a few inches in from the footings, and can be found both inside and
out. These drain water away from the footings, and help to keep them
dry(er). Over the years they fill with silt. Often this can be jetted
out by poking a hosepipe in one end. Its amazing how a damp wall can be
dried out by cleaning the stone drain, and applying a little heat and
ventilation.
