Good basement finishing jobs nowadays typically rely on the sump pump and interior French drain solution I mentioned earlier, but just as much on specialized insulation and building materials specifically designed for high-humidity, mold-friendly environments: steel studs, purple drywall, polyisocyanurate foam board insulation sealed with seam tape and spray foam and silicone sealant, a raised floor or a tile floor laid over a wateproofing membrane, and PVC trim.Your apartment here is obviously a basement apartment, judging from the window placements.
