The water heater in the attic is twelve years old. The ceiling under it just told you so.

Hard Edwards Aquifer water eats a tank from the inside, and in San Marcos the tank often sits above a bedroom or in a garage that shares a wall with the den. By the time the stain shows, the insulation and the top of the drywall are already soaked. Call us now and tell us what you see. We hand the call to an independent local water damage provider who works Hays County houses every week.

Shut the tank valve, then look at the rooms you did not expect

If water is still coming, close the cold-water valve on top of the heater, or the house valve in the meter box near the sidewalk. Flip the breaker for any room where water reached a plug. Then stop and think about where it went, not just where it dripped.

A San Marcos house sits on a concrete slab, so water does not fall into a basement. It runs sideways under the laminate, soaks into the bottom of the drywall, and surfaces as a swollen baseboard in the next room. Water from an attic tank follows the top plate of the walls and comes down inside them.

The provider we send you to starts with a moisture meter, not a saw. Every room on the floor below the leak gets a reading, and the readings decide what opens.

Talk to someone now about the water in your San Marcos home

Describe what you walked into, in plain words. We pass the call to an independent local provider who works slab leaks, freeze breaks, attic water heaters, and river flooding across San Marcos and Hays County.

  • Say which rooms are wet and whether water is still coming in.
  • Mention a warm patch on the tile or a water meter that spins with every tap closed.
  • Tell us if the water heater sits in the attic or the garage, and whether the ceiling under it is sagging.
  • Say whether the water came from a pipe inside the house or up from the street, a creek, or the Blanco.
  • Tell us if you are the owner, a tenant, or a landlord with students in the house.
  • Have the address, a gate code if there is one, and a number where you can be reached.
  • Call even if the floor looks dry now and the room just smells like a wet towel.

Six things the crew does in a wet Hays County house, and why each one matters to you

What happens What it means for you
Meter readings on the floor and bottom foot of every wall, including rooms that look fine Water that ran under the slab-edge flooring into the hallway gets found before the laminate buckles
Attic checked above any ceiling stain before the drywall is touched A failed drain pan or a split line is found and stopped instead of painted over
Slab lines traced by sound and pressure before any concrete is cut One opening where the leak is, not three where it is not
Dehumidifiers sized for a Central Texas summer Drywall and cabinet bases reach their dry target instead of stalling at damp for a week
Floodwater from the Blanco or a creek treated as contaminated Carpet, pad, and lower drywall that soaked up silt come out instead of being dried and hidden
Photos and readings dated from the first visit Your adjuster, or your landlord, gets a record instead of your memory

Things to do before the truck pulls into the driveway

Get belongings off the wet floor and open every cabinet door under a wet counter. Lift the corner of the carpet if you can, so air reaches the pad. Photograph each wet room and the ceiling before anything leaves the house. If this is a rental, text the photos to the owner or the manager now, with the time.

Then make the call. Whether this turns out to be extraction, drying, or a hunt for a slab leak is the provider's call, not yours. Say what you see and let the provider sort out the rest.

Why San Marcos houses get wet the way they do

San Marcos sits right on the Balcones Fault. West of I-35 the ground is Edwards limestone and the Hill Country starts in the back yard. East of the interstate it is Blackland Prairie clay that swells in a wet May and shrinks hard in August. The same fault that opened Wonder World Cave also feeds the springs at Spring Lake, and the clay side works the supply lines under the slab with every season.

This is the heart of Flash Flood Alley. On May 24, 2015, the Blanco River went from under 15 feet to a crest of 43.08 feet at San Marcos in a matter of hours and put water through Blanco Gardens, while the Wimberley gauge upstream estimated 44.9 feet. On October 30, 2015, the All Saints flood did it again and closed the I-35 bridge over the Blanco. The city counted 1,558 housing units damaged across the two floods. Then came February 2021, when a week below freezing split attic and exterior-wall lines across every neighborhood in town.

Repairs that touch plumbing, electrical, or framing inside the city go through the City of San Marcos permit desk, and the provider should tell you which parts of the job need one.

Does a Texas homeowners policy pay for any of this?

A tank that let go overnight or a pipe that split in a freeze is the kind of sudden loss many Texas policies respond to. A slab leak that ran for months is often treated as gradual, and some policies pay for the tear-out but not the pipe. River flooding is almost never covered by a homeowners policy at all; that is a separate flood policy. What your policy pays is a question for someone who has read it, and that is not us. The provider documents every room, logs readings from the first hour, and gives you a written scope. Your adjuster reads that and decides.
