This basement was previously finished with assorted materials that claimed to be 'waterproof' and 'mold-tough', including greenboard and waterproof sheetrock. A quick removal of the cabinets & counter top reveals a wall riddled in black mold.
Sandwiching your typical wood baseboard trim up against drywall is never good in a moisture situation. The homeowner now sees the effects of basement moisture.
Your basement, regardless of how 'dry' it is, still allows water to wick through the porous concrete or stone foundation. Putting up conventional wood/drywall walls only traps the water that wicks through and doesn't allow it to evaporate. Leaving the perfect real estate for reproducing black mold.
It is no news to many homeowners that mold is extremely dangerous, and many will say that don't have any signs of mold. It is what the homeowner can't see that is where black mold loves to dwell.
