When we bought our house four years ago (new construction), the basement had insulation but the basement wasn't finished (there was also no vapor barrier on the inside - just the fiberglass insulation). We were considering finishing the basement but when we pulled back insulation on the side and rear parts above the foundation of the basement found that the plywood walls were wet and had black mold/mildew. Examining the outside, the clapboard seemed dry. There is no visible signs of moisture elsewhere in the in house, although we considering poking a hole or two in the wall (on the first floor) above the most serious wetness areas. There appears to be two ways for the water to get in: (1) from behind the clapboard, but that part of the house looks dry, or (2) wicking up the outside of the foundation wall and then wicking up the plywood. Note: there is no interior water issue in the basement - everything appears bone dry. Our question is: who would be good to investigate and help solve this problem? Also, have you experienced something similar in the past.
Your help in this matter is greatly appreciated.
