How long can a hidden leak go unnoticed?
A slow leak can go unnoticed for weeks or even months, depending on the flow rate and where it's located. Small drips may evaporate before you see any signs. Regular checks of your water meter and listening for unusual sounds can help you catch it sooner.
Can a leak cause mold even if I don't see water?
Yes. Mold can grow in damp areas even without visible pooling. The moisture from a hidden leak can create the right conditions behind walls or under floors. A musty smell is often the first clue. If you suspect mold, consider having a mold professional assess the area.
What should I do if I suspect a hidden leak?
Start by turning off all water-using appliances and checking your water meter for movement. Listen near walls and floors for running water. If you can't find the source, contact local water damage pros to perform a hidden leak detection. They have the tools to find it without tearing up your home.
