Plumbing Leak Detection in Marquette, MI

Hidden leaks cause real damage. Swick finds the source before it becomes a bigger problem.

Not every leak announces itself. Some hide behind walls, beneath slabs, or under crawlspace insulation for months before any visible sign appears. By then, the water damage, mold risk, and structural compromise can far exceed the cost of the original repair. Professional leak detection locates the source before that damage compounds.

Swick Home Services provides leak detection for homes and businesses throughout Marquette and the Upper Peninsula, using diagnostic methods that find leaks without unnecessary demolition or guesswork.

Why Leaks Go Undetected

Hidden leaks share a few common traits: the water pressure holds, no obvious pooling appears, and the problem seems abstract until a bill arrives or a ceiling stain shows up.

Common signs that warrant a leak inspection:

    • A water bill that has increased without a change in usage
  • The sound of running water when all fixtures are off
  • Unexplained drops in water pressure
  • Warm or soft spots on floors, particularly over a slab
  • Mold or mildew odor in spaces that should be dry
  • Discoloration or bubbling on walls, ceilings, or flooring

In the Upper Peninsula, freeze-thaw cycling creates additional pressure on pipes, joints, and supply lines. A micro-fracture that forms in late fall can expand significantly over a winter and become a significant leak by spring. Homes with older copper or galvanized plumbing are particularly vulnerable.

What Leak Detection Involves

Professional leak detection is a diagnostic process, not a repair. The goal is to isolate the source with precision so the repair is targeted rather than exploratory.

Depending on the situation, detection methods may include:

Acoustic Listening Equipment

Picks up the sound signature of pressurized water escaping a pipe, allowing technicians to trace the location through walls, floors, or soil without opening surfaces.

Pressure Testing

Applied to supply lines to identify where a system loses pressure, helping narrow the leak to a specific segment of pipe.

Video Pipe Inspection

Used for drain lines and sewer laterals where camera access can identify cracks, joint failures, or root intrusion that may be introducing water where it shouldn't be.

Thermal Imaging

Detects temperature differentials in walls and floors caused by water migration, useful for identifying leaks inside finished surfaces.

Each method targets a different type of leak. A supply line leak under pressure behaves differently than a slow drain leak or a slab leak, and the detection approach reflects that.

Slab Leaks and Foundation Moisture

A slab leak occurs when a supply or drain line embedded in or running beneath a concrete foundation develops a failure. Because the pipe is inaccessible without cutting, slab leaks are among the most destructive if left unaddressed.

Indicators specific to slab leaks include persistent warm spots on floors, unexplained cracks in flooring or baseboards, and high water bills with no visible source. In some cases, the ground around the foundation may show saturation or heaving.

Early detection limits the repair to a targeted access point. Delayed detection often requires more extensive remediation of flooring, subflooring, and in some cases the structural slab itself.

Leak Detection and Related Services

Leak detection is often the starting point for a broader plumbing repair. Once a leak is located, Swick technicians can proceed with the appropriate repair in the same visit when the scope is clear.

Common follow-on services include:

If the leak has caused water damage that extends beyond plumbing, Swick can coordinate with remediation contractors as part of the restoration process.

Suspect a Leak? Don't Wait.

Water damage gets worse the longer a leak goes unfound. If something feels off — a higher bill, a sound you can't locate, a stain that appeared out of nowhere — it's worth a call. Swick Home Services serves Marquette and the Upper Peninsula with licensed plumbers and the diagnostic equipment to find what's hiding.
