How do I tell a slab leak from a leak in the wall?
A slab leak tends to show at floor level: a warm spot, damp carpet or a wet baseboard, often with a water meter that moves when everything is off. A wall leak usually stains the wall higher up. Only a plumber's test confirms the location, so shut off the main and have one check.
Try the simple checks first. Turn off every fixture and appliance, then look at the water meter. If the dial or low-flow indicator keeps moving, water is leaking somewhere between the meter and the house. Listen near floors and walls for a faint hiss.
A plumber has pressure tests and acoustic or electronic leak detection to narrow the location. The slab leak signs guide walks through the clues in more detail, and the crew's moisture map can help show which rooms are wet while the plumber works.
What happens to my flooring?
It depends on the material and the water category. Carpet pad is usually removed, laminate and engineered wood often cannot be saved, solid hardwood may be dried carefully, and tile typically stays in place. The crew reads moisture and explains each choice before any flooring comes up.
Slab water has a particular habit: it pushes upward and spreads sideways between the concrete and the flooring. That is why a damp spot the size of a dinner plate can hide a wet area several times larger.
Floating floors such as laminate swell at the seams and often have to be lifted. Carpet itself can sometimes be cleaned and dried, but the pad beneath it holds water and is generally discarded. Wood floors have to be monitored, because boards can cup well after the surface seems dry.
You approve what comes up. Skipping removal can slow drying, but the choice is yours, and the crew should explain the trade-off first.
What does homeowners insurance usually say about slab leaks?
It varies. Texas policies often treat plumbing and slab leaks specially, sometimes with separate deductibles or exclusions for foundation damage, and long-term leaks are usually excluded. Ask your agent how slab leaks are handled, take photos before anything is moved and keep the moisture readings.
Standard homeowners policies often cover sudden and accidental discharge from plumbing, but a leak that ran slowly for months is a different matter. Whether damage to the slab or the pipe itself is included depends on the policy, which is why a call to your agent early is worth making.
The crew can give you readings and photos of the wet area and what was removed. Those records help whichever way coverage goes. The Texas Department of Insurance can help with claim questions and complaints.
Can mold follow a slab leak?
Yes, particularly if flooring or wall bottoms stayed damp. The EPA's 24 to 48 hours is a guideline, not a deadline, and materials that dried inside it may still have growth. Texas licenses mold assessors and remediators separately, and licensed remediation is generally required for 25 contiguous square feet or more.
Mold likes the dark space between flooring and slab. A musty smell that persists after drying is a reason to ask for an assessment rather than a reason to assume the job is finished.
The mold inspection and mold remediation pages explain how those roles differ. The drying crew removes the moisture that feeds growth, and any assessment or remediation is a separate step.
