Residential Leak Detection in St. Louis

Hidden water leaks rarely stay small. What starts behind a wall or under a slab can quietly lead to warped flooring, mold growth, foundation stress, and rising water bills.

Our role is to eliminate guesswork. We focus on confirming whether a leak exists, identifying the exact source, and giving you clear findings so repairs can be planned accurately.

If you’re seeing warning signs or your water usage doesn’t make sense, call (314) 400-7201 to schedule a residential leak detection evaluation and protect your home from further damage.

How Residential Leak Detection Works

Finding the Leak Before Opening Walls

Effective leak detection starts with verification and isolation. Rather than cutting into drywall or flooring to “see what’s wet,” we narrow down whether the issue is in supply plumbing, drain lines, slab piping, pools, or exterior systems. This step-by-step diagnostic process prevents costly trial-and-error repairs.

Technology-Driven, Non-Invasive Methods

Our technicians use specialized tools designed to trace water movement and pressure behavior behind finished surfaces. Once the leak location is identified, we document the findings so your plumber or contractor can make a focused repair with minimal disruption.

Non-Invasive Leak Detection Methods Explained

Acoustic Leak Detection

Acoustic equipment detects the sound frequency created when pressurized water escapes a pipe. This method is highly effective for supply lines behind walls, under flooring, and beneath slabs when conditions allow clear sound transmission.

Infrared (Thermal) Imaging

Thermal imaging helps identify temperature differences caused by hot water leaks or moisture evaporation. It’s commonly used to map affected areas and guide more precise testing rather than serving as a standalone solution.

Tracer Gas Testing

For hard-to-locate leaks, tracer gas can be introduced into an empty line. Sensitive sensors detect where the gas escapes, making this method useful when background noise or pipe material limits acoustic accuracy.

Signs You May Need Residential Leak Detection

Common Warning Signals

• Unexplained increases in your water bill

• Sounds of running water when fixtures are off

• Warm spots on floors or damp areas that don’t dry

• Water stains, bubbling paint, or soft drywall

• Musty odors or recurring mold

• Cracks in flooring or slab foundations

When to Call a Professional

If two or more of these symptoms appear, or your water meter shows continuous usage with everything off, it’s time to stop guessing and schedule professional leak detection.

Slab Leak Detection for St. Louis Homes

What Causes Slab Leaks

Slab leaks often result from pipe corrosion, soil movement, abrasion, or aging materials. Seasonal temperature changes in the St. Louis area can add stress to plumbing beneath concrete foundations.

How Slab Leaks Are Diagnosed

Diagnosis typically includes plumbing isolation, pressure evaluation, and acoustic testing, sometimes supported by thermal imaging. The goal is to pinpoint the leak location so concrete removal is limited to only what’s necessary.

Pool and Irrigation Leak Detection

Pool Leaks vs. Evaporation

Some water loss is normal, but consistent drops beyond evaporation often indicate a plumbing or structural issue. Professional pool leak detection verifies the cause before costly deck removal or repeated repairs.

Irrigation and Sprinkler Line Leaks

Underground irrigation leaks can waste water without obvious surface signs. Professional detection locates the exact break so repairs can be targeted without trenching large areas of your yard.

What to Do Before Scheduling Leak Detection

Helpful Steps for Homeowners

• Locate and test your main water shutoff

• Perform a water meter test with all fixtures off

• Note when symptoms occur (overnight, hot water use, pool running)

• Document visible moisture or damage

This information helps speed up diagnosis and improves accuracy during the inspection.

Leak Detection vs. Leak Repair

Leak detection is a diagnostic service focused on locating and documenting the source of water loss. Repairs—such as plumbing work, excavation, or restoration—are typically handled by licensed plumbers or contractors. Separating detection from repair ensures fixes are based on verified information, not assumptions.
