Leaving a leak alone is the absolute worst thing you can do, even though we know calling for service can be a stressor all on its own. Even after a short amount of time, the leak can lead to a serious mold infestation, which threatens the health of your family. Over time, the leak will also damage the structure of your home — floors, foundations, ceiling, and walls. And eventually, a leak will damage your home plumbing even further, leading to more expensive repairs or eventually replacements.
