North Central San Antonio · ZIP 78213
78213 covers the north-central band around Castle Hills, Dellview and Shearer Hills — solid mid-century neighborhoods built out largely between the 1950s and 1970s, now at exactly the age where original building systems reach the end of their service life.
Our north side branch at 18210 Sonterra Pl is the closest crew base to this ZIP, covering Stone Oak, Hollywood Park, Shavano Park and the US-281 North corridor. Within 78213 we serve Castle Hills Enclave, Dellview, Shearer Hills, Greater Harmony Hills, Jackson-Keller and Lockhill.
1950s–1970s single-story ranch homes on slab, with some split-level and two-story stock in Castle Hills. Original cast-iron drain lines and early copper supply are widespread, and many properties are on their original sewer lateral.
This ZIP sits in the age band where cast-iron drain lines fail — roughly 50 to 70 years of service is where they give out, and much of this housing is right there now. Salado Creek tributaries cross the eastern side of the ZIP and drive localized flooding, and the mature tree canopy that makes these streets attractive also puts root systems into sewer laterals.
The losses we attend most often in this ZIP:
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 north side branch dispatches to 78213 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.
It is worth getting a camera inspection rather than waiting. Cast-iron drain lines from that era typically last 50 to 70 years, and much of this neighborhood is at or past that point. A plumber's camera survey costs far less than a below-slab failure, and it tells you whether you are looking at a repair now or a replacement in five years.
That is usually either a failed wax seal or a blocked or broken drain line beneath the slab. Either way, the water reaching the subfloor is contaminated. Stop using that bathroom, and get a plumber to diagnose the line while we handle the contaminated material and drying. Water tracking under vinyl or tile from a toilet base spreads further than it appears.
