Locate Concealed Leaks Before Opening Walls or Floors

Water staining, damp flooring, musty odors, running-water sounds, or an unexplained increase in water use can point to a concealed leak. The visible symptom doesn’t always reveal the source, especially when water travels through walls, ceilings, concrete, or soil.

We provide non-invasive leak detection services for Redmond homes, businesses, and municipal properties. Our goal is to narrow the source before repair access is created, reducing unnecessary cutting, excavation, or removal of finished materials.

Call (425) 276-6850 to request leak detection for your Redmond property and pinpoint the suspected source before repairs begin.

Professional Leak Detection Without Destruction™

As The Original Leak Specialist™, we bring more than 50 years of industry experience to concealed leak investigations. Our trained technicians use proprietary detection technology and equipment developed to locate leaks without destructive searching as the first step.

We investigate water loss and moisture concerns across pressurized plumbing, drains, slab lines, walls, and underground systems. Each service starts with the reported symptoms and the parts of the property or system most likely to require targeted testing.

Water, Drain, & Sewer Leaks We Locate

Leak symptoms vary by system. A pipe leak may appear as damp drywall or flooring, while a drain or sewer problem may cause staining, odors, or moisture only when a fixture is used.

Our leak detection capabilities include:

Hidden plumbing leaks: Locating concealed water leaks in walls, ceilings, and floors.
Slab and foundation leaks: Narrowing the location of leaks beneath or near concrete and foundation areas.
Drain leak detection: Investigating suspected leaks connected to drainage piping and fixtures.
Sewer line leaks: Examining suspected leakage within sewer lines.
Outdoor leaks: Locating water loss involving irrigation lines and other underground systems.
Pool and spa leaks: Testing water-containing structures and their related plumbing.

Clear Pricing and Respect for Your Property

Our technicians are trained in advanced detection methods and treat each property with care. We arrive on time, complete the project within the stated time frame, and leave the premises clean.

Our Know Before You Go approach provides honest, upfront pricing before work begins. After the investigation, we explain our findings clearly so property owners can discuss the probable repair area and next steps with a contractor.

Signs a Redmond Property May Have a Hidden Leak

A concealed leak may first appear as a higher water bill, recurring moisture, discoloration, musty odors, running-water sounds, or an unexplained wet area near a foundation or yard. Consider arranging an inspection when the source isn’t visible, particularly if:

The water meter records use while fixtures and appliances are off.
Moisture returns after a surface has dried or been cleaned.
Staining appears on a wall or ceiling without a visible plumbing failure.
Warm, damp, or damaged flooring suggests a possible slab line problem.
Odors or moisture appear when a sink, shower, toilet, or appliance drains.
Outdoor soil remains wet without recent rain or irrigation use.

How to Perform a Water Meter Leak Check

The City of Redmond advises property owners to stop all water use, record the meter reading, wait without using water, and check the meter again. Movement of the meter’s flow indicator while no water is being used may signal a leak.

Closing the property’s main shutoff can help narrow the suspected area. If the meter continues to change, the leak may be in the underground water line between the meter and the property. If the meter stops changing, the problem may be within the property’s plumbing. This check can indicate water loss, but it can’t identify the precise location.

How Non-Invasive Leak Detection Works

We begin by reviewing the symptoms, plumbing history, accessible system components, and areas where moisture or water loss has appeared. The testing method depends on whether the suspected problem involves supply piping, drainage, a slab, an underground line, or another system.

Diagnostic methods may include:

Acoustic leak detection: Listening for sound created by water escaping from a pressurized pipe.
Pressure testing: Checking whether an isolated plumbing section maintains pressure.
Moisture measurement: Comparing moisture levels across materials to narrow the affected area.
Thermal imaging: Identifying temperature patterns that may warrant further targeted testing.
Video inspection: Viewing accessible portions of drain or sewer piping from inside the line.

No single method fits every property or leak. We combine relevant observations and measurements to identify the most probable source before creating repair access.

Responsibility for Water Lines in Redmond

According to the City of Redmond, the city is responsible for leaks from the water main through the meter. Leaks between the meter and the property are generally the property owner’s responsibility.

After a leak is confirmed, the property owner may need to coordinate with a detection provider, repair contractor, and water utility. Detection identifies the suspected source and repair area; completing the repair is a separate stage.

Request Leak Detection for Your Redmond Property

We locate suspected leaks in residential, commercial, and municipal properties using targeted, non-invasive diagnostics. Clear findings give you and your repair contractor a more precise starting point without treating visible damage as proof of the source.
