I am from eastern NC. I have a home that was built in 1955. It is a ranch style home with central air. I have a bathroom in the home which the walls are sweating bad. It looks like tears coming down everywall. The paint is peeling. Also all the walls in the home are plaster ( slick ) ....and in perfect shape. This problem started about 6 months ago. When I found a small leak near the bathroom. I had it repaired by a roofer and thought my problem was solved. Well now my perfect plaster has started to break and chip away. I have been in the attic. I have checked for leaks, condensation and any type of moisture....Nothing found. I have started noticing that there is several places in the hallway of the home that the sweating is occuring about a foot from the ceiling. I do have 9' ceiling in the home....The attic does not have open gable ends or a roof vent...But the home does have openings around the eaves( where the boxing is).NC is having a very hot summer 95 to 115 degrees with humidity. Also the house does have a crawl space. If you have a suggestion...please reply.
