What kind of structural damage can humidity cause?
Nature, as usual, will find a way to maintain balance. Because humid indoor air tends to be under higher pressure than outdoor air, indoor air constantly pushes its way outward to the area of lower pressure — right through wood, plaster, insulation, and concrete. This process can cause insulation to deteriorate; paint to blister and peel; unsightly stains on walls and ceilings; and rotting of floors, wall supports, and other structural supports, including foundation damage.
