Water Damage in San Antonio
San Antonio homes face water damage risks you won't find in every market. Our clay soils shift with the seasons, and that foundation movement is a leading cause of slab leaks and pinhole pipe failures — especially in older neighborhoods like Alamo Heights, Monte Vista, and Terrell Hills, where galvanized or polybutylene plumbing is still in place. I've crawled more crawl spaces and traced more mystery leaks in this town than I can count, and the pattern is always the same: the sooner we get eyes on it, the less it costs to fix.
Then there's the weather. When a Hill Country thunderstorm drops inches of rain in an hour, flash flooding hits fast. Low-lying areas, homes near creek beds, and properties with poor drainage can go from dry to several inches of water before you finish your coffee. Appliance failures are another local culprit — San Antonio's hard water shortens the life of supply lines to washing machines, dishwashers, and ice makers, and those slow leaks often hide behind cabinets for weeks.
We serve homeowners and businesses across areas we serve including San Antonio, Boerne, New Braunfels, Helotes, Schertz, Converse, Stone Oak, and Alamo Heights. If you're standing in water right now, call us at (210) 599-9726 — we'll be on our way.
Types of Water Damage We Handle in San Antonio
Different water sources call for different tools, drying protocols, and timelines. Here's how we handle the water problems we see most across San Antonio.
Burst & Frozen Pipes
A failed supply line can release water into walls and cabinets faster than most homeowners expect. San Antonio's occasional hard freezes put exposed pipes in attics and exterior walls at risk, and the city's shift-prone clay soils are hard on buried lines too. We stop the source, extract quickly, and dry the wall cavities so a pipe leak doesn't become a mold job.
Ceiling & Roof Leaks
Roof leaks and HVAC condensation often show up as a brown stain on the ceiling long before the damage is visible from above. Water travels along framing, so the leak is rarely directly above the stain. We trace it to the source, dry the attic and ceiling assembly, and replace saturated drywall.
Slab Leaks
San Antonio's expansive clay soils shift with wet and dry cycles, and that movement is a leading cause of slab leaks under foundations. These leaks are slow and hidden — you may notice a spike in your water bill, a warm spot on the floor, or a musty smell before you ever see water. We locate the leak, dry the affected flooring and structure, and coordinate with your plumber on the repair.
Appliance & Water Heater Leaks
San Antonio's hard water shortens the life of supply lines to washing machines, dishwashers, ice makers, and water heaters. Those slow leaks often hide behind cabinets or in closets for weeks before they're discovered. We extract the standing water, dry the surrounding cabinetry and flooring, and check for hidden moisture with thermal imaging.
Storm & Flood Damage
When a Hill Country thunderstorm drops inches of rain in an hour, flash flooding can push water into homes in low-lying areas and near creek beds. Storm water is typically contaminated, so we treat it as Category 2 or 3 with proper protective equipment and antimicrobial treatment. See our storm & flood damage restoration service for the full process.
Sewage Backups (Category 3)
A sewage backup is Category 3 "black water" — it carries bacteria, viruses, and parasites, so it should never be handled with a shop vac or household fans. Backups usually trace back to a clogged main line, a failing septic system, or storm water overwhelming the city sewer. We contain and remove the waste, dispose of unsalvageable materials, and disinfect the area. See our sewage cleanup service for what Category 3 cleanup involves.

Why Immediate Response Matters
Mold in 24–48 Hours
According to the EPA's guide on mold and moisture, mold colonies can begin forming within a day of water exposure. Fast extraction and drying stops mold before it starts.
Structural Damage Risk
Standing water weakens drywall, warps flooring, and compromises structural framing. Every hour increases repair costs.
Health Hazards
Contaminated water (Category 2 & 3) introduces bacteria and pathogens. Professional extraction and sanitization protect your family's health.
