Getting the water down safely
Pumping starts gradually so the pressure outside the walls does not crack a slab or a block wall. Water that came up from the ground or through a drain is treated as contaminated, with protective gear and containment. Clean water from a failed pipe or water heater is simpler, but it still has to be removed quickly.
What gets removed and what gets dried
Carpet pad, baseboards and the bottom of drywall wick water upward and usually come out. Concrete, joists and framing are dried in place, since they cannot be replaced cheaply. Finished lower levels with trim, built-ins and cabinets need extra care because moisture hides behind them.
Dehumidifying the lower level
A closed, below-grade room stays humid for a long time, so dehumidifiers do most of the late-stage work. Readings steer the run until the slab and wall bottoms look dry. Structural drying covers that stage, and storm and creek flood cleanup applies when outside water is the source.
