5 Signs You Have a Hidden Water Leak

Hidden water leaks are the worst kind. They damage your home slowly, balloon your water bill, and cause lasting moisture damage — all before you have any clue something’s wrong. Here are the 5 most common signs we see when called out for leak detection in Waco.

1. Your water bill is rising with no explanation

If your water bill jumped 20%+ and your usage habits haven’t changed, you likely have a leak. A small leak can waste 90+ gallons a day. Compare bills month over month and to last year’s same month – a sudden spike usually means a leak somewhere.

2. You hear running water when no fixtures are on

Stand in your house with all fixtures off. If you hear water running in the walls or under the floor, that’s a leak. The sound usually means a pressurized pipe is losing water continuously.

3. Wet spots or warm spots on the floor

Slab leaks (under your concrete foundation) often show up as warm spots or wet areas on the floor. Hot water leaks heat the slab; cold water leaks leave wet patches. Either is a serious issue requiring professional detection.

4. Musty smell that won’t go away

A musty or mildew smell often indicates water somewhere it shouldn’t be. Even small leaks behind walls or under cabinets can cause hidden structural damage within 24-48 hours. If you smell it, find the source quickly.

5. Stains or peeling paint on walls and ceilings

Brown stains on a ceiling are classic signs of a leak in the floor above. Peeling paint, bubbling drywall, or warped baseboards all indicate water damage. The visible damage is usually smaller than the actual affected area.

What to do if you suspect a leak

The fastest first step: turn off the water main, then check your water meter. If the meter is still moving with everything off, water is flowing somewhere it shouldn’t be.
