Written Reports

A slab leak losing a single gallon per hour moves more than 8,700 gallons of water in a year — almost all of it into the soil under your foundation. That's not a number we invented; it's straightforward arithmetic on what a pinhole-sized breach in a pressurized line actually does over time. And it's why slab leak work isn't something a general plumber should approach with a stethoscope and a guess.

Carlos Plumbing Service has handled slab leak detection in Austin homes for three generations of family ownership. We've watched the equipment improve, the methods refine, and the diagnostic precision get to a point where opening drywall on the wrong wall is no longer a tolerable mistake.

SLAB LEAK SPECIALISTS

Our Slab Leak Detection & Repair Services in Austin

Electronic Slab Leak Detection (Acoustic Method)

Isolates the exact sound signature of escaping water. We narrow the leak to a small working radius — often a single tile — saving you time and money on repair access.

Thermal Imaging for Hot-Water Slab Leaks

Detects temperature differentials on the slab surface. Used as a cross-check with acoustic detection for maximum accuracy on hot-water lines — the most common type in Austin.

Pressure Testing & Line Isolation

We isolate hot/cold lines and branches to confirm exactly where the loss is occurring. This eliminates guesswork and provides the foundation for an accurate repair quote.

Spot Repair Service

Once located, we open a minimal section, replace the failed pipe segment, pressure test, and restore the floor. Ideal when the rest of the line is sound.

Pipe Rerouting & Bypass

For repeat leaks on the same line, we reroute through walls or attic, abandoning the problematic slab section for a permanent solution.

Slab Leak Detection & Repair in Austin: Our Process

  1. 1. Initial assessment — Visual inspection and history review.
  2. 2. Meter test — Confirms and quantifies water loss.
  3. 3. Pressure isolation — Identifies hot/cold side and branches.
  4. 4. Acoustic detection — Pinpoints leak location.
  5. 5. Thermal cross-check — For hot-water leaks.
  6. 6. Written findings — You review data before the quote.
  7. 7. Repair scoping — Spot repair, reroute, or referral.
  8. 8. Execution — Defined scope, timeline, and cost.

This sequence takes 90 minutes to three hours for diagnostics. We charge a flat diagnostic fee (credited toward repair) and provide full transparency.

The Equipment That Makes the Difference

  • Acoustic ground microphones with multi-band filtering
  • Thermal imaging cameras for sub-surface mapping
  • Tracer gas detection equipment
  • Inline pressure recorders
  • Borescope cameras & precision concrete cutting tools

Accuracy comes from professional equipment — not guesswork. We minimize disruption by opening only what is necessary.

Why Three Plumbers Can Quote Three Different Numbers for the Same Slab Leak

The variance isn’t necessarily dishonesty. It’s diagnostic precision — or the lack of it.

A plumber who hasn’t precisely located the leak is pricing for an area... A plumber who has located the leak within an 18-inch radius is pricing for a known-scope repair...

The question to ask any plumber isn’t “what does it cost?” It’s “where exactly is the leak?”
