Hi, I had an open breezeway between the side door of my house and the separated garage (they share the same roof). I hired a contractor to wall it in. He used cedar channel wood siding. He also installed two doors on the once open sides of the new room. There is no insulation and it sits on a concrete slab. The room is about 180sq ft.
It was great through the winter, but now that the summer is here, the room is filled moisture and the concrete slab is very wet.
-I've opened the windows on the doors to let air pass through, but it has little effect on the moisture.
-I installed a small fan near the floor blowing air outside, but I don't think it is doing anything.
Any information on how to fix this problem would be greatly appreciated.
