Not every hidden leak is under the slab. In Thomson we also trace leaks inside walls, where a slow supply-line drip soaks insulation and framing; under yards, where the service line from the meter runs; and in pools and irrigation, which can masquerade as house leaks on the water bill. Our Leak & Slab Detection covers the whole property: we isolate zones with pressure tests to learn which part of the system is losing water, then narrow it with acoustic and thermal tools until the location is certain.

Ask for the full report in writing: what was tested, what the readings showed, where the leak is marked, and what the repair options and prices are. You will need it for the repair decision, for insurance, and for your records if the home is ever sold. We provide it as standard on every Thomson detection visit.

How leak detection works

Yard service-line leaks, between the meter and the house, have their own tells: a perpetually green or soggy strip, a meter that spins with the house shutoff closed, the sound of running water at the meter box. Detection here combines the meter isolation test, acoustic listening along the line’s path, and sometimes tracer gas: the line is filled with a safe hydrogen-nitrogen mix, and a sniffer at the surface finds where it escapes. Because East Georgia soils shift with moisture, service lines here fail at joints and where they enter the foundation, and the locator marks both the leak and the line’s path so the repair trench is exactly as long as it needs to be.

Signs you need leak detection in Thomson

• Cracks appearing in floors, walls, or tile.
• Damp, warped, or discolored flooring with no visible source.
• A water meter that moves with everything in the house turned off.
• Drains gurgle when the washing machine or dishwasher discharges.
• The same drain clogs again within months of a professional clearing.

What’s included

• Non-invasive detection first, always
• Fixture and irrigation elimination before buried-leak hunting
• Thermal and acoustic cross-confirmation of the location
• Marked repair point, so openings are small and targeted
• Pressure test after repair to prove the fix held

East Georgia: how local conditions affect leak detection

Inland from the Sandhills, the red clay beneath Thomson swells with every wet spell and shrinks with every dry one, and the copper supply lines buried under slab foundations ride that movement year after year. The stress concentrates where the pipe passes through the slab edge or turns at a fitting — the points that cannot flex — until a joint weeps or a pinhole opens in the thinned copper. Because the leak sits under concrete, it travels before it shows: wicking up through the slab, running along the pipe trench, or feeding the clay where it pools unseen.

The sandy soils nearer Thomson’s Sandhills country fail differently: they wash away. Tropical-system downpours drive water through fast-draining sand along buried supply lines, eroding the bedding that supports the pipe until a section spans a void and sags under its own weight plus the soil above it. That sag stresses every joint in the span, and the eventual leak opens where the stress peaked. Either sign in a Thomson yard is worth a pressure test of the supply line before the void grows.

Finding the leak in a Thomson home starts with proving it exists: the main valve shut, all fixtures off, and the meter watched — movement means water is leaving the system somewhere it should not. Acoustic listening equipment then maps the leak’s sound through soil and concrete, with the loudest point marking the break to within inches; on hot lines, thermal imaging reads the warm signature the leak paints on the slab. For Thomson homes, that choice between repair and reroute is where an accurate location pays for itself.

What affects the cost of leak detection in Thomson

Access drives labor on leak repairs more than the pipe itself. A leak under an open garage slab is straightforward; the same leak under a finished kitchen with stone tile means careful removal, protection, and restoration of expensive finishes. Wall leaks behind tile showers or built-ins take similar care. We price the access honestly: the protection, the surgical opening, and the restoration to a paint-ready or tile-ready state. The pipe repair in the middle is often the quickest part of the job.

• What sits above the leak: flooring type and finishes
• Protection and dust control during the work
• Surgical opening size versus exploratory demolition
• Restoration to finished condition

Common questions

What is the warm spot on my floor?

Almost always a hot-water slab leak: escaping hot water warms the concrete above it. Thermal imaging confirms it in minutes.

Should I repair or reroute a slab leak?

A first pinhole in a sound line: spot repair. Multiple prior repairs or aggressive water eating the pipe: reroute overhead and abandon the buried run. We quote both.

Will my insurance cover this?

Sudden water damage is typically treated differently from long-term seepage, which is why prompt detection and documentation matter. Our written report is formatted for filing.

How long does detection take?

Most Thomson homes are diagnosed in a single visit. Pressure isolation narrows the zone quickly, and acoustic pinpointing usually follows within the same appointment.

Why does the same drain keep clogging in my Thomson home?

A clog that returns after every clearing is a symptom, not the disease — clearing removes the blockage but leaves the cause. In Thomson the usual structural causes are a belly where the lateral sagged in settling sand, a mat of pine roots growing through a loose joint, or cast-iron pipe scaled so narrow that normal waste cannot pass.
