I have a question about crawlspace humidity.
I live in an old house (c. 1914) with a huge crawlspace. It's approximately 75ft by 25ft, staring at 10 ft ceilings at one end and going to 4ft at the other. It has an earth floor covered with a vapor barrier. The space is not sealed, but there are no gaping holes to the outside either.
The humdity in this space in the summer is constantly between 70% and 80%. I have talked to several people about this and have received 2 different pieces of advice. Half the people say I should seal it up and get a whole house de-humidifier down there, and the other half say I should put in air vents or an exhaust vent to get outside air circulating. I am very confused by this as they seem to be opposites!
Any advice you could offer will be much appreciated.
