How to Spot a Hidden Water Leak Before It Costs You

Hidden leaks are sneaky by nature — they run behind walls, under floors, or beneath slabs long before any visible sign appears. A few early indicators are worth checking regularly.

• Your water bill increases without a change in household usage
• You hear running water when every fixture is off
• The water meter continues to move with everything shut off
• A warm spot appears on the floor, often over a hot water line
• A faint musty smell develops with no obvious source

If you notice any of these, professional leak detection can usually pinpoint the source using acoustic and thermal tools — without cutting into walls or floors to search for it.
