Not every leak announces itself with a drip. Many happen inside walls, under slabs, or behind fixtures — running up your water bill and damaging your home long before you notice.
In our humid South Florida climate, a hidden leak can also feed mold, so catching it early matters.
Warning signs of a hidden leak
- ✓A water bill that jumps with no change in usage
- ✓The sound of running water when everything is off
- ✓Warm spots on the floor (a clue to a hot-water slab leak)
- ✓Musty smells, or stains on walls, ceilings, or floors
- ✓Mold or mildew that keeps coming back in one spot
- ✓Cracked or buckling flooring and peeling paint
The water meter test
Turn off every water fixture and appliance in the home. Find your water meter and note the reading or watch the leak-indicator dial. Wait 1–2 hours without using any water, then check again. If the reading changed, you likely have a leak somewhere in the system.
Why hidden leaks need a pro
Pinpointing a leak inside a wall or under a slab without tearing up your home takes specialized leak-detection tools and experience. Catching and repairing it early is almost always far cheaper than repairing water-damaged framing, flooring, and drywall later.
