Isolating where the water is going
Supply side or drain side, inside the house or between the meter and the wall. Isolating the section first keeps the search small instead of opening several walls to look.
Leak Detection and Repair
A water bill that jumped, a damp patch with no obvious source, or the sound of water at night. San Marcos Emergency Plumber finds the leak before anything gets cut open, then repairs what is actually broken.

Signs That Need Attention
- A water bill that rose with no change in how you use water
- The meter dial still moving with every fixture closed
- A musty smell in one room, or a patch of carpet that stays damp
- Paint bubbling on a wall, or a baseboard that has swollen
- Grass that stays green over one strip of the yard in August
A simple test at home: close every tap, do not run the dishwasher or the irrigation, then look at the meter. If the small dial is still creeping, water is going somewhere. Note roughly how fast it moves and tell us — a fast spin and a slow creep suggest very different failures.
What the Service Includes
Not every visit needs every item below. San Marcos Emergency Plumber separates the repair you called about from anything optional, and the quote shows both.
Locating without unnecessary damage
Acoustic listening, pressure testing and moisture readings narrow the leak down to a small area. Opening a neat access panel beats demolishing a wall and guessing.
Repair options explained before work starts
Once located, you are told what failed, what the repair involves and whether a section replacement or a reroute is the more sensible answer for that run of pipe.
Your Options
Between the meter and the house is a common and easily missed spot, especially on larger lots out toward the Hill Country where the run from the meter or the well to the building can be long. A leak there shows up on the bill long before it shows up on a wall.
Inside the house, older galvanized supply pipe in the pre-war housing around the older county-seat towns tends to fail from the inside out, so one pinhole usually means others are coming. That is worth knowing before you decide how much pipe to replace.
If the water is under the floor, the job becomes a slab leak repair. If a line has already opened up, go straight to burst pipe repair. Where the damp is around the heater, our repair versus replacement guide helps you decide what to do with the unit, and how it works explains the visit itself.
Leak Detection & Repair Questions
What affects the cost of leak detection?
How much of the system has to be isolated and tested, and how accessible the suspected area is. A single fixture supply is quick; a whole-house test with a slab involved takes longer. San Marcos Emergency Plumber quotes the detection and the repair separately so you can see both.
Can you find a leak without breaking anything?
Locating it, usually yes — listening equipment, pressure isolation and moisture readings do most of the work. Repairing it always needs access somewhere, but knowing the exact spot keeps that access small.
My bill is high but I cannot see any water. Is that possible?
Very. Leaks under a slab, in an irrigation line or between the meter and the house can run for months with nothing visible indoors. San Marcos Emergency Plumber starts at the meter and works inward. See the slab leak warning signs if the floor feels warm anywhere.
