Find the Source With Leak Detection Without Destruction™

We locate hidden water and sewer leaks in Minneapolis homes, businesses, and municipal properties. Our non-invasive approach identifies failures in pressurized plumbing, slab lines, water service lines, and sewer or drain systems before repair work begins.

Moisture can travel through framing, flooring, concrete, or soil, so a stain or damp area may be far from the actual leak. We use diagnostic testing to narrow the location instead of relying on exploratory demolition.

Finding Leaks Across Different Plumbing Systems

The right diagnostic approach depends on how the affected system carries water or waste. We evaluate the symptoms and plumbing involved before selecting the appropriate testing methods.

Our plumbing diagnostic services include:

Pressurized plumbing leak detection: We locate concealed leaks in supply piping inside walls, beneath floors, and underground.
Slab leak detection: We investigate plumbing beneath concrete slabs without beginning with broad, destructive access.
Sewer and drain leak detection: We assess concealed leaks and other potential failures in sewer and drain lines.
Cause-and-origin investigations: We trace unexplained moisture when the source isn’t visible or confirmed.

In a home, the first clue may be a higher water bill, damp flooring, or the sound of running water. Commercial and municipal properties may have larger, more complex piping networks, but accurate diagnosis remains essential before targeted access and repair can be planned.

Over 40 Years of Non-Invasive Leak Detection

We’ve developed proprietary techniques and equipment for locating hidden plumbing failures. Depending on the system, an assessment may involve pressure or flow checks, acoustic leak detection, thermal imaging, moisture observations, tracing, or sewer camera inspection.

Our Leak Detection Without Destruction™ approach focuses on gathering evidence before finished surfaces are opened. It reflects the standards behind The Original Leak Specialist™: rigorous technician training, clear explanations, respect for the property, and a clean work area after the visit.

Detection and repair are separate decisions. We explain the likely system and leak location so you or your chosen repair contractor can determine the next step.

Signs You May Need Plumbing Leak Detection

A hidden leak may first appear as a change in water use, sound, moisture, temperature, or odor rather than an obvious puddle.

Warning signs to document include:

Unexplained increases in water bills or metered use.
Damp, warped, or unusually warm flooring.
Discoloration on walls or ceilings.
Musty or recurring sewer odors.
Running-water sounds when fixtures aren’t operating.
A water meter leak indicator that continues moving when water isn’t being used.

Before cutting into finished surfaces, check accessible fixtures and note where and when symptoms appear. With faucets, appliances, and other water-using fixtures off, observe the water meter leak indicator. If it moves, check fixtures one at a time to help narrow the issue. Concealed plumbing may still require professional testing.

What to Expect During a Plumbing Leak Assessment

We begin by asking about the property, the symptoms, and when the problem occurs. Those details help us determine whether the source may involve a pressurized line, slab plumbing, a sewer or drain line, or another moisture source.

A diagnostic visit typically involves:

Reviewing the symptoms: We gather details about water use, sounds, odors, visible moisture, and previous observations.
Testing the plumbing: We select non-invasive methods and technology based on the system involved.
Comparing the findings: We evaluate relevant pressure, sound, temperature, flow, moisture, tracing, or camera observations.
Explaining the likely location: We review the findings so you can make an informed repair decision.

The assessment is designed to provide enough location information for targeted access. It doesn’t require you to authorize work from a particular repair provider.

Private Sewer Laterals and City-Owned Sewers in Minneapolis

A sewer odor, backup, wet area, or unexplained drainage issue may originate inside a building, along the private sanitary lateral, or within public infrastructure. The private sanitary lateral connects a property’s plumbing to the city-owned sanitary sewer.

The City of Minneapolis investigates reported sewer overflows, odors, and street issues to determine whether a problem involves the public system or a private lateral. When a blockage or defect is on the private portion, the owner may need a professional drain service. Confirming the location helps clarify responsibility before excavation or repairs are planned.

Plan Your Next Plumbing Step With Clearer Information

Once we identify the likely system and leak location, you can make a more informed decision about targeted access and repair. Our Know Before You Go approach explains pricing before diagnostic work begins.
