What Causes Water Damage in San Marcos
San Marcos sits at the foot of the Balcones Escarpment, where the Blanco River meets the San Marcos River. Heavy rain upstream can send floodwater into town, and the city’s ZIP code has recorded hundreds of flood insurance claims since 2015.
The Memorial Day floods of May 2015 sent the Blanco River into San Marcos neighborhoods. Creeks and low crossings in town also flood in heavy rain. Floodwater is Category 3 water and needs full cleanup. Flood damage restoration →
Many San Marcos residents rent, often in apartments and duplexes. A leak from an upstairs unit, a failed water heater or an overflowing washer can damage several homes at once. Emergency water removal →
San Marcos averages about 6 freezing nights a year, so pipes in exterior walls and attics are often unprotected. Winter Storm Uri in February 2021 burst pipes across Central Texas. Burst pipe cleanup →
Spring storms can bring hail and strong wind that crack shingles and lift flashing. Leaks show up as ceiling stains, sometimes days after the storm. Ceiling water damage →
Only about 24% of homes in these ZIP codes were built before 1980, so much of the housing is newer. Even newer homes see supply-line, water heater and appliance failures.

Why the First 24–48 Hours Matter in San Marcos
After a flood in San Marcos, warm humid air keeps drywall, insulation and carpet pad wet. Mold can start within 24 to 48 hours, so extraction and drying should begin as early as it is safe.
MC 28% → 12% until materials hit dry targets.When San Marcos 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 Marcos. 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.

Renters and Owners in San Marcos: Check Flood Coverage
- Rising water from the Blanco or San Marcos River needs a separate flood policy through the NFIP or a private insurer.
- Renters can buy NFIP contents coverage for their belongings. The landlord’s policy does not cover them.
- New NFIP policies usually take 30 days to start, so buy before the spring and fall wet seasons.

Tell your landlord or property manager right away, in writing if you can, and take photos. The owner is usually responsible for repairing the building. Your belongings are covered only by your own renters policy, and flood damage to them needs separate flood coverage. If you are asked to arrange cleanup, call DryRoute.
03What should I do when the river is rising?

Twelve inches of moving water can carry away most cars. Return only when officials say it is safe, then call to start cleanup.
04How do I deal with water damage in San Marcos after a flood?
Stay out until power is off and officials say the area is safe. Photograph everything before moving it. Floodwater is contaminated, so soaked drywall, insulation, carpet and pad below the water line usually have to go. A local team extracts the water, cleans and disinfects, and dries the structure before any rebuild.
05What does water damage repair in San Marcos involve?
It starts with finding and stopping the source, then extracting water and removing materials that can’t be saved. Air movers and dehumidifiers dry what remains, with moisture readings taken along the way. Once everything tests dry, drywall, flooring and trim are replaced. Your local team explains each stage and its price first.
