How To Detect Hidden Water Leaks In Your Home

Detecting hidden water leaks early can help you avoid costly damage and water waste. Start by checking your water meter: turn off all water-using appliances and fixtures, then note the meter reading. Wait 1–2 hours without using water, and check again. If the reading has changed, you likely have a leak.

Look for signs like musty odors, mold or mildew growth, damp spots on floors or walls, bubbling paint, or warped wood. In bathrooms and kitchens, inspect under sinks and behind appliances for moisture or staining. Unexpected spikes in your water bill are another red flag.

Listen for running water sounds when no fixtures are on, especially at night. If you suspect a slab leak or pipe behind a wall, a professional leak detection service—like A&G Plumbing and Drain—can pinpoint the problem using thermal imaging or acoustic equipment.

Addressing hidden leaks promptly protects your home’s structure and can significantly reduce your monthly water costs.
