The signs

Leaks announce themselves.

You just have to know what to listen for. Any one of these is worth a call.

01 A climbing water bill Usage that creeps up month over month with no change in habits — the most common first sign.
02 A meter that won't stop Everything off, meter still spinning — water is going somewhere. That's a diagnosis, not a mystery.
03 Warm spots on the floor A hot-side slab leak warms the concrete above it — often paired with a water heater that never rests.
04 Running water you can hear A hiss or flow sound in the walls or floor with every fixture off.
05 Pressure that dropped Low or falling pressure for no reason — sometimes a leak, sometimes a failing component. We find which.
02 · How we find it

Found before anything gets opened up.

Nobody should jackhammer a slab on a hunch. We isolate the system from the meter inward — pressure testing, meter observation, and targeted diagnosis — until the leak is pinned to its source. Then you see what we found, what it takes to fix, and what it costs. Before any repair starts.

+How do I know if I have a slab leak?

A climbing bill, a meter that spins with everything off, warm floor spots, running-water sounds, or a water heater that never rests. Any one of these is worth a diagnosis call.

+How do you find a hidden leak?

We isolate the system from the meter inward — pressure testing, meter observation, targeted diagnosis — until the leak is pinned to its source. Nothing gets opened up on a hunch.

+Is a slab leak an emergency?

It shouldn't wait. Water under a slab erodes soil and can damage the foundation — and you're paying for every gallon in the meantime. Call and we'll get eyes on it quickly.

+Will insurance cover it?

Many Texas homeowner policies cover access and water damage from sudden leaks — usually not the pipe repair itself. We document the diagnosis and repair thoroughly so you have what your adjuster needs.
