What happened in Appleton
CCS inspected this basement in Appleton on November 26, 2025, as a free mold assessment, and documented it with 18 photos. The owner received a written estimate for remediation.
The basement has painted block walls and a concrete floor. Along the bottom of several walls a dimpled plastic drainage membrane had been installed at the joint between the wall and the floor, part of an interior drain system. Above it, the block was stained dark in a band and in the corners, with black growth climbing up from the floor and under the rim joist where the insulation meets the top of the wall.
The crew also photographed the floor drain, the plumbing stack and drain lines, and the stair area. An interior drain system handles water that comes through the wall, but the block above it can still stay damp enough to grow mold, especially where airflow is poor and things are stored close to the walls.
