Southwest San Antonio · ZIP 78224
78224 covers Valley Hi, Indian Creek and the Medina Base area in the city's south-west. The Medina River and its tributaries define drainage across much of this ZIP, and the housing is largely mid-century slab construction on flat, clay-heavy ground.

1950s–1970s single-story slab homes dominate, built through the period of Lackland and Kelly-driven expansion. Original plumbing is common, and the clay soils beneath these slabs are among the more active in the county.
Two drivers: the Medina River and Indian Creek watershed on the drainage side, which produces genuine flood exposure on the lower parcels, and expansive clay movement cracking under-slab plumbing on the structural side. The flat terrain compounds both, since water that arrives has nowhere to go quickly.

Water running right now? Shut it off at the main if you can reach it safely, cut power to affected areas at the breaker if water is near outlets (never stand in water to do it), photograph everything before moving anything, then call (844) 476-1017. Our south side branch dispatches to 78224 around the clock.
Water damage frequently leads to mold, and fire losses almost always involve water too. We handle all three from the same branches: mold remediation with containment and independent verification, and fire and smoke damage restoration including emergency board-up.
That is the classic sign of a slab leak. Turn everything off inside and check whether the meter is still creeping — if it is, water is escaping between the meter and the house, most likely under the slab. We locate it acoustically and thermally before any concrete is opened, which usually saves both money and floor.
The Medina and its tributaries do produce flooding on the low-lying parcels in and around this ZIP during significant rainfall. Whether your specific address is exposed is worth checking on the public county flood maps. Also worth knowing: Indian Creek and the local drainage channels rise faster than the river itself, so the water that reaches your property often arrives before anyone is watching the river level.
In San Antonio's humidity, mold can begin establishing within 24 to 48 hours on damp organic material. That is why the response window matters so much and why drying to a documented moisture target — rather than until it looks dry — is the actual standard. Surface-dry material with a wet core will grow mold behind the finish.
