Thanks for posting. I’m in the process of moving, and the house I’m buying has a partially finished basement with a high humidity level.
Here’s what has been suggested to me/I’m doing to relieve the problem. (Keeping the water away from the outside of the house goes a long way to relieve inside moisture problems. I realize you said you have a dry basement, but can’t hurt.)
1) Have the immediate exterior (3 or so feet closest to house) regraded to make sure water runs away from the house, rather than toward it when it rains. Keep mulch back from the house by a foot or two. (this helps with insect/termite/carpenter ants etc as well as getting rid of the moisture retaining mulch near the house)
2) Make sure downspouts have extensions, either above or below grade, that carry the water away from the house, rather than just dumping onto the ground beside the house.
3) Window wells should be covered.
4) As others mentioned, concrete is good at wicking, so keep everything off the floor. I will probably end up having the carpeting that is currently down there removed, as it smells musty at the moment (it didn’t earlier in the summer) Yet another thing I was not planning on doing, but such is the situation of buying a different house.)
5) Run dehumidifier, large capacity, and it will go via hose into the sump hole (even though the basement has a high humidity level, the sump pump supposedly never runs) That way it will run as much as necessary, rather than waiting to be dumped.
6) I’m having a duct put in from the heating/ac system into the finished part of the basement. I have to have some heating system changes made anyway, so this will be added to that.
I don’t know if any of those suggestions will help you, but maybe they will help someone.
