Not every hidden leak is under the slab. In Godfrey 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 Godfrey detection visit.

How leak detection works

Slab leaks have a specific anatomy worth understanding. Water lines run beneath or within the concrete slab that forms the home’s floor and foundation. Where the pipe passes through the slab edge or changes direction, stress concentrates, and Metro East & Southern Illinois soil movement adds cyclic flexing that work-hardens copper until a pinhole opens. Hot lines fail first and most noticeably: the escaping hot water warms the slab above it, creating the classic warm floor spot, and it also accelerates the corrosion that opened the pinhole. Cold-line slab leaks are sneakier, showing only as a bill spike or damp flooring. Detection distinguishes them fast, because a warm signature on thermal imaging points straight at the hot line, cutting the search area dramatically.

Signs you need leak detection in Godfrey

• A water meter that moves with everything in the house turned off.
• Mildew smells or mold growth on a ground-floor wall.
• Low water pressure that appeared gradually across the house.
• A depression forms in the yard over the buried line.
• Orange stains appear in toilet bowls and sinks.

What’s included

• Same-week detection appointments in Godfrey in most cases
• Honest answer when the evidence says there is no leak
• Second-opinion detection before you authorize slab work
• Reroute-versus-repair comparison with real numbers
• Restoration plan for the opening: concrete, tile, drywall

Metro East & Southern Illinois: how local conditions affect leak detection

Hidden leaks in Godfrey homes announce themselves through the water bill, the sound of running water with everything off, or damp spots where none should be. Mine subsidence can shear a buried service and open a leak with no surface evidence at all — the water drains into the shifted ground instead of pooling. Detection starts with isolation: pressure-testing sections of the system to prove which run is losing water before any excavation begins.

Acoustic and electronic methods do the pinpointing. Listening equipment picks up the hiss of pressurized water escaping; on buried services, correlators triangulate the leak between two contact points. In Godfrey mine country, the locate has to account for shifted ground — the pipe may not be where the original plans say it is, so the trace follows the actual pipe, not the assumed path. Non-invasive location turns a leak from a guessing excavation into a targeted dig.

Once located, the decision is reroute versus repair — with mine awareness built in. A single accessible split gets repaired; a run crossing active subsidence gets rerouted around the movement zone or replaced with flexible-coupled pipe bedded to tolerate the next shift. In Godfrey homes with aging galvanized systems, one pinhole leak is often the first of many, so pressure-testing the rest of the run tells the honest story. Every detection visit ends with the whole system holding pressure on the gauge.

What affects the cost of leak detection in Godfrey

What the leak has already damaged affects the total. A leak caught from a bill spike may need only the pipe repair. One that has been running for months can mean mold remediation, damaged flooring, or compromised sub-slab soil, which are separate trades with separate costs. Our detection report documents visible damage honestly so you can plan, and we coordinate with the repair crew to keep the plumbing scope tight and clear. In Godfrey, early detection is genuinely the difference between a plumbing bill and a construction project.

• Extent of secondary damage: mold, flooring, finishes
• How long the leak has been active
• Whether soil under the slab needs attention
• Plumbing scope kept separate from restoration scope

Common questions

How do you find a leak under concrete?

Acoustic sensors, thermal imaging, and pressure tests triangulate the spot. We open concrete only where the leak actually is, and the opening is small and targeted.

Is a slab leak an emergency?

It can wait days, not months. Unchecked leaks erode soil under the slab and invite foundation trouble, so this week beats next month.

What does leak detection cost?

The detection visit is flat-rate and includes the full investigation plus a written report. The repair is quoted separately once we know what and where the problem is.

Can you detect leaks in walls too?

Yes. Moisture mapping and thermal imaging trace wall and ceiling leaks to their source, and we open surgically once, in the right place.

How do I fix iron-stained fixtures?

In Godfrey, dissolved iron in well water oxidizes into orange stains. A water test measures the level, then oxidation and filtration at the entry point remove the iron before it reaches fixtures — cleaning the stains without treatment just resets the clock.
