Need Water Removal or Flood Cleanup in San Antonio, TX?
Three sources cause most water damage in San Antonio homes. Flash flooding is the first, and it has deep roots here: the 1921 flood reshaped the city, and creeks like Salado still pose a real flood risk during heavy rain. Slab leaks are the second, caused by the expansive clay under most homes, known locally as black gumbo, which swells and shrinks with the seasons and cracks the plumbing beneath the slab. Roof and ceiling leaks are the third, since sudden downpours overwhelm roofing and gutters and push water inside. We respond to all three with advanced extraction equipment, structural drying, and documented moisture readings, backed by 65-plus years of ServiceMaster experience serving Southeast San Antonio and Bexar County.
Flash Flood & Storm Water Cleanup
Flooding is part of San Antonio's history, not just its forecast. The city sits in Flash Flood Alley, where storms off the Gulf hit the Balcones Escarpment and send water downhill fast. The 1921 flood is the event that changed everything, killing dozens and devastating the West Side creek neighborhoods, and it led directly to the Olmos Dam and the bypass channel that became the River Walk. The risk hasn't gone away: the 1998 flood dropped more than 11 inches in a day, and the 2013 Memorial Day storm closed Highway 281 after 17 inches fell on the Olmos Basin. We handle rapid extraction, treat floodwater as contaminated, and dry the structure while documenting the loss for your claim.
Slab Leak Water Damage Restoration
Slab leaks are the water problem hiding under the house. The Blackland Prairie clay beneath San Antonio, black gumbo, swells when it's wet and shrinks when it dries, and that constant movement stresses the water lines running under a slab foundation until one cracks or pulls apart at a joint. Because the leak sits under the concrete, it usually shows up indirectly, through an unexplained jump in the water bill, a warm spot on the floor, or a musty smell with no obvious source. Our crews use moisture detection to locate the leak beneath the flooring, coordinate with plumbers on the repair, and dry the affected area with protocols built for slab-on-grade construction.
Roof & Ceiling Leak Water Damage Cleanup
The same storms that flood the streets go after the roof. San Antonio's heavy downpours come fast and hard, and they overwhelm roofing and gutter systems that drain fine in ordinary rain, driving water under shingles and through flashing into the attic and ceilings. A ceiling stain is often the first visible sign, but the water has usually spread through insulation and framing by then. Our crews trace the intrusion to its point of entry, extract and dry what the storm left behind, and monitor moisture in the attic and ceiling assemblies until the readings come down, so a roof leak doesn't turn into a mold problem overhead.

Why Water Damage Can't Wait in San Antonio Homes
Water spreads fast, and delay turns a contained problem into a structural one.
- Within the first hour: Floodwater or a burst slab line spreads across floors and soaks into drywall, baseboards, and flooring before most homeowners realize how far it's gone.
- Within 24 hours: Wet materials begin breaking down and mold sets in, especially through San Antonio's humid summer stretches when moisture lingers instead of drying.
- Within days: A slab leak left alone can wash away the soil supporting your foundation, turning a plumbing problem into a structural one.
The sooner the drying starts, the more of the home can be saved rather than replaced.
