Southtown · ZIP 78204
King William and Lavaca hold the highest concentration of 19th-century architecture in San Antonio, and they sit directly on the San Antonio River. High property values, irreplaceable original material and genuine river proximity make 78204 one of the ZIP codes where getting the first 24 hours right matters most.
Our downtown headquarters at 105 Soledad St is the closest crew base to this ZIP, covering downtown, the River Walk, Southtown and the near-north corridor. Within 78204 we serve King William, Arsenal, Southtown, Lone Star, Collins Garden and Lavaca.
German-built limestone and brick mansions from the 1860s through 1890s, Victorian frame homes, and 1920s bungalows in Lavaca and Collins Garden. Thick masonry walls, original heart-pine floors and plaster over lath behave nothing like modern assemblies when they get wet — masonry in particular holds moisture for a very long time and will quietly feed mold behind an interior finish that looks perfectly dry.
The river is the obvious factor, and properties on the low side of King William Street and along the Arsenal reach carry real flood exposure. Less obvious but more frequent: these houses have had plumbing, HVAC and additions retrofitted repeatedly over 140 years, and condensate lines, second-floor bathrooms added into original structures, and aged supply lines account for most of the losses we actually attend here.
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 downtown headquarters dispatches to 78204 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.
Slowly and with measurement. Limestone and soft brick hold a great deal of water and release it gradually, so aggressive heat or airflow can drive salts to the surface and spall the face. We monitor with a combination of surface and deep-probe readings and hold the drying rate down deliberately. It takes longer than drying drywall and we will give you a realistic timeline at the start rather than an optimistic one.
Know how your lot drains and where water goes when the river is high. Bexar County flood maps are public and searchable by address, and the properties on the low side of King William Street and along the Arsenal reach sit meaningfully lower than those a block up. Knowing your elevation before an event matters more than anything you can do during one. Keep a record of what the house looks like dry, too — photographs of rooms and contents are worth a great deal later.
Frequently, if we get to them quickly. Old-growth pine is dense and does not absorb as fast as modern engineered flooring, which buys some time. We use floor-drying mats to pull moisture up through the boards rather than lifting them, monitor for cupping, and in most cases the boards flatten as they dry. Once the subfloor has delaminated or the boards have crowned, replacement becomes the honest answer.
