Gather the observations
Changes that may warrant a slab leak assessment
Warning signs can include unexplained water-bill increases, running-water sounds with fixtures off, warm or damp areas underfoot, new cracks and musty odors around baseboards. These observations warrant attention, but a plumbing investigation is needed to determine what they mean.
Keep the observations separate: where the moisture appears, when a sound is heard and how water use changed. Explain any recent plumbing work or previously repaired leak. Avoid assuming that all symptoms share one cause. Useful records help the plumber understand the sequence, while the actual condition must be established at the property.
