“We called on a Sunday because our heater went out during a freeze and they were able to come out the same day. This is a locally owned company and you can tell they care about their customers. They were very up-front and honest, and their prices are very fair. They were able to come out the very next day and replace our system. I would highly recommend this company.”

How much does leak detection cost in San Antonio?
Standard leak detection in San Antonio runs $125 to $350, with most jobs landing near $275. A comprehensive test — including slab leaks, which need acoustic and thermal equipment rather than a visual check — runs $200 to $600 depending on how much of the house has to be ruled out.

Signs of a hidden leak
A water bill that climbs with no change in how you use water is the clearest one. After that: a warm patch on a tile floor, the sound of running water when every fixture is off, a spot of lawn that stays green through an August dry spell, cracking or lifting in flooring, or a musty smell in one room that never quite clears.
Pressure is the subtle one. A shower that has gone weak, or a tap that takes longer to run hot than it used to, often means a supply line is losing water somewhere you cannot see.
What leak detection costs in San Antonio
| SERVICE | SAN ANTONIO RANGE, 2026 | WHAT DRIVES IT |
|---|---|---|
| Standard leak detection | $125 – $350 | Most jobs land near $275. A single suspected line, accessible, located and confirmed. |
| Comprehensive or slab test | $200 – $600 | Acoustic and thermal across more of the house. Cost tracks how much has to be ruled out, not how long it takes to find. |
| The repair itself | Quoted after detection | A line in a wall is a different job from one under six inches of concrete. Both prices given before anything opens. |
Detection and repair are priced separately on purpose — you are not committed to us for the repair because we found the leak, and you will have the number for both before a decision is needed.
Slab leaks and pipe leaks are not the same problem
San Antonio sits on expansive clay. It swells when it rains and shrinks when it does not, and it moves the slab with it — which is why supply lines run through concrete here fail more often than the pipe itself would suggest. Copper in direct contact with slab and with alkaline soil corrodes from the outside in.
A pipe leak in a wall or ceiling is usually cheaper and faster: locate, open, repair, patch. A slab leak means deciding between breaking concrete to reach the line and rerouting the run overhead, and the right answer depends on where the leak sits and what is above it. We price both before anything is opened, so the choice is yours rather than ours.
How we find a leak without opening walls
Isolate
We shut off fixtures in sequence and watch the meter to establish that water is genuinely moving when nothing is running, and roughly how much.
Listen and image
Acoustic equipment picks up the sound of water escaping a pressurized line through concrete or drywall. Thermal imaging shows the temperature difference a hot-water leak leaves behind. Between them, most leaks get located to within a small area without cutting anything.
Confirm, then quote
We verify the location before opening anything, and you get a written price for the repair before the first cut. Guessing wrong is what turns a leak into two repairs.

Frequently Asked Questions
How much does leak detection cost in San Antonio?
Standard detection runs $125 to $350, with most jobs around $275. A comprehensive test including slab leaks runs $200 to $600, depending on how much of the house needs ruling out and what equipment the job takes.
Can you find a leak without cutting into my walls?
That is the point of the equipment. Acoustic listening devices and thermal imaging locate most leaks through concrete and drywall without opening anything. We confirm the location before the first cut, so when something does get opened it is the right spot.
Does homeowners insurance cover a slab leak?
Policies differ, and we are plumbers rather than adjusters — so check with your carrier. The pattern most San Antonio homeowners run into is that resulting water damage is often covered while the pipe repair and the concrete work to reach it frequently are not. What helps a claim is documentation: a dated detection report, photos before anything is opened, and an itemized invoice. We provide all three whether you file or not.
How do I know if it’s a slab leak or a pipe leak?
Warm spots on the floor, unexplained damp at the base of a wall, and the sound of water with everything off point toward a slab leak. A ceiling stain or damp drywall points to a supply or drain line in the structure. Detection settles it — and the two need genuinely different repairs, so it is worth knowing before anyone quotes.
How fast can you come out for a leak in San Antonio?
A leak actively losing water gets treated as urgent, and there is cover around the clock for it. Damage compounds while you decide, so the call is worth making before you have settled on a plan.
