The housing stock in Valley Hi — and why it matters

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.

What causes water damage in 78224

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.

The losses we attend most often in this ZIP:

  • Medina River and Indian Creek watershed flood exposure
  • Clay soil movement fracturing under-slab supply lines
  • Slow-draining flat lots holding stormwater against foundations

Questions from Valley Hi property owners

My water bill doubled but I can't see a leak anywhere.

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.

Does the Medina River flood this area?

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.

How long before mold starts after water damage?

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.

Ask to see credentials — from us or anyone else

Before any technician starts work on your property, you are entitled to ask them who they are and what qualifications they hold, and to ask to see documentation. That applies to us and to every other contractor who knocks on your door. Ask at your own discretion, take your time, and do not feel awkward about it — a crew that is happy to be asked is the kind you want in your house. If anyone refuses or rushes you past the question, treat that as your answer.
