Slab Leak Water Damage in New Braunfels, TX
There is one stripe of tile in the hallway that feels warm under bare feet, and the water bill from New Braunfels Utilities doubled with nobody filling a pool. The baseboard at the end of that hall has started to lift. Nothing is dripping anywhere. In a slab house, that is a hot-water line leaking under the concrete. This site routes you to an independent local provider who handles slab leaks and the damage they cause in New Braunfels and across Comal County.
Finding the line under the concrete, then dealing with what it soaked
A slab leak has no puddle to follow, so the crew starts with the meter: with every fixture closed, the dial still turns. Then they shut the water heater valve to learn whether it is the hot side, walk the floor with a thermal camera to find the warm trail, and use acoustic listening gear and a pressure test to pin the spot. The plumber opens one section of slab, or reroutes the line through the attic and abandons the old one in place.
While that happens, the water-damage side of the job begins. The floor over the leak and the walls around it are metered, because the water has been spreading under the tile and into the drywall for as long as the leak has run.
Steps to take while the leak is still under the floor
Turn off the water heater's cold supply if the floor is warm; that stops the hot side and often slows the leak. If the meter still spins with the heater off, close the main at the curb. Do not pull up tile yourself; the pattern of damp under it is the evidence the plumber uses. Photograph the lifted baseboards, the warm stripe, and the meter reading. Keep a copy of the high water bill. Then call and say what you found.
What a slow leak under the slab does to the rooms above it
Weeks of warm water under a floor loosens tile from its mortar, swells laminate, and feeds moisture up the drywall from the bottom. The baseboard lifts, the paint bubbles at the floor line, and the room smells faintly damp. In a bad case, the clay under the slab softens and the floor develops a hump or a dip. Once the line is fixed, structural drying pulls the moisture back out of the slab and the walls, and the readings decide which drywall and flooring stay. Long-running slab leaks are the ones most likely to grow mold inside a wall, so the drying has to be finished, not just started.
If the leak turned out to be in a wall or the attic rather than under the floor, the work is leak detection followed by the same drying.
Limestone to the west, clay to the east, and copper in between
The Balcones Fault Zone runs under New Braunfels, and it splits the county's soils. West and north, from Vintage Oaks and Bulverde to Canyon Lake, houses sit on Edwards and Glen Rose limestone that is honeycombed with caves and shifts along fractures. East of I-35, from Creekside out to Marion and Seguin, the Blackland clay swells after a wet spring and shrinks hard in a summer like 2011 or 2022. Both soils move post-tensioned and conventional slabs enough to stress copper, and the hard aquifer water scales and pits the inside of the pipe at the same time.
Houses built from the late 1970s through the 1990s, in Oak Run, Hidden Valley, and the older parts of Garden Ridge, are the ones with copper under the slab and are the most frequent slab-leak calls. Newer subdivisions in Veramendi and Mayfair run PEX, which flexes better, but the fittings under the slab still fail.
Slab leak coverage varies more than any other water loss. Many Texas policies pay to tear out and repair the damage but not to fix the pipe, and some exclude slab leaks entirely or cap them. Only your adjuster can say, and this site makes no promise. The provider's readings and photos are what the claim rests on.
Calling about a warm floor or a spinning meter
Say where the warm spot is, whether the meter turns with everything off, and how long the bill has been high. Mention lifted baseboards or loose tile. Have the address and a callback number. Call (830) 356-7502.
