South San Antonio · ZIP 78221
78221 runs south along the Pleasanton Road corridor through Palo Alto Park, Mission Highlands and Villa Coronado. The terrain is flat, the housing is mostly post-war slab construction, and drainage is the recurring theme in almost every call we take here.
Our south side branch at 4715 Roosevelt Ave is the closest crew base to this ZIP, covering Harlandale, the Mission Reach, Brooks and the South Side. Within 78221 we serve Mission Highlands, Villa Coronado, Stonegate, Palo Alto Park, South Center and Pleasanton Road.
1950s–1980s slab-on-grade single-story homes predominate, with newer subdivision sections toward the southern edge. Slab foundations across expansive South Bexar clay soils move seasonally, and that movement is directly implicated in the plumbing failures we find beneath them.
Expansive clay soil is the underlying driver here. It swells when saturated and shrinks in drought — San Antonio gets both, often in the same year — and that cyclical movement stresses and eventually cracks the drain and supply lines cast beneath slabs. Add flat terrain that ponds stormwater rather than shedding it, and the two combine.

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 78221 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.
Very often they are, and in both directions. Expansive clay moving under the slab cracks pipes; a leaking pipe under the slab then saturates the soil locally and makes the movement worse. Fixing one without addressing the other tends to bring you back to the same place. We locate and document the moisture; a structural engineer and plumber handle the causes.
That is a grading and drainage problem, and it will eventually become a foundation and moisture problem if it is not corrected. Water should fall away from the slab on all sides. We can dry and treat what has already got in and identify where it is entering, but the permanent fix is regrading, guttering and extending downspouts well away from the structure.
