Neglecting water damage can lead to severe structural issues in your home, putting the integrity of the building at risk. This includes the foundation, walls, ceilings, and other components, which can result in collapse if left unaddressed. Water infiltration into the foundation can cause walls to shift and crack and ceilings to collapse due to the weight of the water. These long-term effects can be detrimental to both the home and the health of its occupants.
