Hi, I have a problem with a wet wall. I have looked through the forum and found some information on sweating walls due to condensation, but they seem to indicate this would happen mainly in the winter.
We bought this house 2 months ago and this week I noticed a lot of moisture on one of the walls. It has been very hot and humid where I live, and we do not have AC, as it is usually a colder climate here. The moisture is in a small area - about 3 feet of space on an interior hallway wall along the baseboard. The baseboard is also quite wet and I can tell that the wood has experienced wetness before, as it is darker than the baseboard wood throughout the rest of the house. This hallway has marble tile floor and it much cooler than the rest of the house. There is plenty of airflow in the hallway from windows and doors being open. The crawlspace under the house is dry, and there are no pipes running down the wall behind this wall. The wet area is only on a small portion of the wall - as I said, about 3 feet of space in a hallway with probly 30 feet of wall space total. The other side of the wall is the living room; the hallway is in the middle of the house.
Is it possible that this is simply condensation from the hot humid weather?
Thanks so much in advance!
