The process
The a slab leak process, step by step
- 1
Walkthrough and moisture map
The tech who does the walkthrough finds the source and maps how far the water traveled, using thermal imaging and pinless meters.
- 2
Extraction and removal
The extraction crew pulls standing water with truck-mounted units, then removes anything the water category says cannot be saved.
- 3
Drying set to the room
Air movers and LGR dehumidifiers go in sized to the evaporation load of each room, with desiccants for dense Class 4 materials.
- 4
Daily readings to dry
Readings are logged daily, and equipment leaves only when wet materials are within 2 to 4 points of a dry reference material.
Most St. Petersburg homes built from the 1950s on are concrete block on a slab, with water lines running under or through the concrete. When one of those pressurized lines fails, water spreads under the flooring before it shows. The first signs are usually small: a warm patch on tile over a hot water line, grout that stays dark, a floating floor that starts to cup, or baseboards swelling along one wall.
Signs of a slab leak
- A warm or damp area on the floor, often near the kitchen or a bathroom.
- The sound of running water when every fixture is off.
- Cupping or buckling in wood, laminate or vinyl plank flooring.
- A sudden jump in the water bill with no change in use.
How slab leak damage is dried
A plumber locates and repairs the leak, often by opening the slab or rerouting the line. The restoration side starts with a thermal camera and moisture meters to map how far the water spread under the flooring and into the walls. Floating floors and laminate over wet concrete usually have to come up, because water trapped between the plank and the slab will not dry through the floor. Tile that is still firmly set can sometimes stay. The drying team then runs air movers, LGR dehumidifiers and, on dense concrete, desiccant dehumidifiers until the slab and wall bottoms reach the drying goal.
Older homes with cast iron drains under the slab can also leak waste water; that is a sewage cleanup job, not a clean-water one. For leaks inside walls rather than under the floor, see burst pipe cleanup.
Why concrete takes longer
Concrete is a Class 4 material under the IICRC S500 standard. It holds water deep in its pores, so drying a slab takes targeted airflow, dry air and patience, confirmed with readings.

Questions
Slab Leak Water Damage questions in St. Petersburg
Can I leave the flooring down while the slab dries?
Floating floors and laminate usually have to come up, because they trap water against the concrete. Tile that is still firmly set can sometimes stay if readings allow.
How is a slab leak found?
Plumbers use pressure tests, acoustic listening devices and thermal imaging. The drying team uses meters and thermal imaging to map the wet area around it.
Is slab leak damage covered by insurance?
Many policies cover the resulting water damage and access to the pipe, but not always the pipe itself. Coverage depends on your policy, so it is worth checking with your own insurer.
How long does a concrete slab take to dry?
Longer than drywall. Several days is common, and a saturated slab can need a week or more with desiccant dehumidifiers.
Will the leak come back?
Older lines can fail again in another spot. Many owners choose to reroute supply lines through the attic or walls after a second slab leak.
Can a slab leak cause mold?
Yes, under flooring and at the bottom of walls, especially in humid Florida air. Drying to verified readings is how that is prevented.
