The warranty on a house is usually for 5 years, and then you are on your own. Anything can happen, for example a bathroom subcontractor poorly installs your shower enclosure and water seeps into the surrounding wood or spreads to other areas across your foundational concrete slab. All this can be invisible to normal detection. Homeowners have every reason to install a MoistureGuard monitoring system which will immediately alert you to a problem with leaking water or moisture.
