What Happens When You Call DryRoute
What Causes Water Damage in San Antonio
San Antonio is dry much of the year, then heavy storms drop rain on thin soil and limestone that can’t absorb it. Creeks rise, low-water crossings flood, and between storms plumbing leaks do the steady damage.
Central Texas is known as Flash Flood Alley. Salado Creek, Leon Creek and other drainage channels can rise in a single storm, and low-water crossings flood quickly. Floodwater that enters a home is Category 3. Flood damage restoration →
Most homes sit on concrete slabs, and clay soils in many parts of the city swell and shrink between wet and dry spells. That movement stresses water lines under the slab. A warm spot on the floor or a running meter can be the first sign. Water damage cleanup →
Spring thunderstorms bring hail and wind that crack shingles and lift flashing. The leak may not show until the next rain, when stains appear on the ceiling. Ceiling water damage →
San Antonio averages only about 5 freezing nights a year, so outdoor and attic pipes often have no insulation. Winter Storm Uri in February 2021 burst pipes and strained the water system across the city. Burst pipe cleanup →
About 40% of homes in these ZIP codes were built before 1980, a mix of older and newer housing. In older homes, aging supply lines and drains add to the risk.

Why the First 24–48 Hours Matter in San Antonio
San Antonio’s heat makes surfaces look dry early, but water trapped under flooring, in wall cavities and beneath cabinets stays wet much longer. That hidden moisture is where mold starts.
MC 28% → 12% until materials hit dry targets.When San Antonio Freezes
Texas freezes are rare but severe, because many pipes were never built for them.
Days of sub-freezing temperatures burst pipes in attics, exterior walls and garages across the state, including San Antonio. Many Texas homes run water lines where they were never meant to freeze.
Before a hard freeze
- Know where your main shut-off is and make sure it turns.
- Wrap pipes in the attic, garage and exterior walls; cover outdoor faucets.
- Open cabinet doors under sinks on outside walls.
- Keep heat on if you travel.
- If a pipe bursts: shut off the main, cut power to wet areas from a dry spot, then call.

Flash Flood Alley Safety
Creeks here rise quickly after heavy rain.
Never drive into a flooded crossing
Central Texas is known as Flash Flood Alley. Creeks can rise in minutes and low-water crossings flood first.
- Turn around at any water over the road. You can’t see the depth or whether the road is gone.
- A foot of moving water can float a car (NWS).
- Stay out of flooded rooms too: floodwater is Category 3 and can hide live wiring.

San Antonio Water Damage FAQ
Local answers about San Antonio water damage and what happens when you call.
Call Now01Is my San Antonio ZIP code covered?
Yes. All 63 residential San Antonio ZIP codes are covered, including King William, Monte Vista, the Medical Center area and Stone Oak. Enter your ZIP in the checker above to confirm, then call and you’ll be routed to a local team that works in your part of the city.
02Who do I call about a water main break or a flooded street?
Contact San Antonio Water System (SAWS) for water main breaks, and report street flooding or drainage problems to San Antonio 311. If water has reached the inside of your home, get to a safe place first, then call DryRoute to reach a restoration team. Never drive through a flooded crossing.
03How do I know if I have a slab leak?
Common signs are a water bill that jumps without explanation, a meter that keeps moving with every tap off, warm or damp spots on the floor, and the sound of running water. A plumber can locate and repair the leak. A restoration team dries and cleans up the damage it caused.
04Do pipes freeze in San Antonio?
Not often, which is why it hurts when they do. The city averages about 5 freezing nights a year, so many outdoor and attic pipes are unprotected. During Winter Storm Uri in February 2021, pipes burst in homes across the city. On hard-freeze nights, cover outdoor faucets and drip indoor ones.
05Does my homeowners policy cover flash flood damage?
Usually not. Water that rises from outside, including flash floods and overflowing creeks, typically needs a separate flood policy through the NFIP or a private insurer. Sudden indoor leaks, like a burst pipe, are usually covered by homeowners insurance. Check your own policy for details. General information, not insurance advice.
06Who will come to my San Antonio home?
A local restoration team that serves your San Antonio ZIP code. They look at the damage, tell you what work is needed and what it will cost before they begin, and then handle it. If anything is unclear, ask before you agree. There is no charge for calling DryRoute.
