Leaky pipes may severely harm the structure of a home and the wellbeing of its inhabitants. Persistent leaks can cause major water damage including stained ceilings, warped floors and deteriorated walls. This moisture allows mildew and mold to develop - damaging building materials and causing health problems including respiratory issues and allergies. Also, unnoticed leaks can result in huge water bills because of wasted water. Structural damage goes beyond the visible portions and weakens wooden beams and foundations, possibly compromising the whole building's stability. Leaks also draw in pests like termites and ants that could damage the home. Electrical hazards arise when water contacts wiring and creates short circuits and fires. Leaking pipes may also decrease house value, making houses less appealing to prospective buyers.
