While clearing out the area of the large panel stock was found black mold on the walls we have sprayed it with some a Clorox solution kill the mold. The bottle at the base of the wall is that solution and can be sprayed on again if someone is there… Clif and are set to return at 2. Pm to clean the wall and continue building storage. There’s a lot of mold on the wood that was stored there and we are taking steps to dispose of said wood.
