How to Know When You Have a Hidden Water Leak

A hidden water leak can quietly damage your home for weeks before you ever see a drop. Catching it early saves you from mold, rot, and a sky-high water bill.

Common Warning Signs

• A water bill that keeps climbing with no change in your usage
• The sound of running water when every fixture is off
• Warm spots on the floor (a clue to a hot-water slab leak)
• Musty smells, stains, or bubbling paint on walls and ceilings
• Low water pressure that appears out of nowhere

A Simple At-Home Test

Find your water meter and write down the reading. Don't use any water for two hours, then check it again. If the number moved, water is escaping somewhere in your system.

What to Do Next

Shut off your main water valve to stop further damage, then call a licensed plumber. We use leak-detection equipment to pinpoint the source without tearing up your whole house — so the repair stays small and affordable.
