Watch for the signs
Red flags that point beneath the slab
Be on the lookout for unexplained increases in your water bill, warm or damp areas underfoot, the sound of running water when no fixtures are on, new cracks in walls or floors, and musty odors or mildew along baseboards.
Any one of these can have another explanation, which is why detection matters. A record of when each sign appeared and which rooms are involved gives the investigation a useful starting point.
