If you have a high humidity level in your house during the humid months but no moisture problems and start refinishing rooms by adding insulation and sealing all air leaks are you opening up problems for that room (ex: trapping the humidity because of no air flow)?
I ask because I finished up my basement (no moisture problems) prior to Christmas and it had a nice NEW SMELL
. Now that the humid months have started my basement is developing a smell. It doesn't smell musty but there is a smell. I put a hygrometer down there and the humidity was at 74%. So I took it upstairs and the humidity was around 70% and dropped to 68% in the morning. So could I be trapping the humidity in the basement (partial/walk out basement)? Hope that makes sense.
I know its time for a Dehumidifier. I'm waiting on a quote for a central AC unit to be installed.
thanks
