Hidden leaks found without tearing into your walls. Acoustic sensors, thermal cameras, and pressure testing pinpoint the source — then we fix it before the damage spreads.

Non-Invasive Detection Same-Day Repair Slab Leak Specialists

Call (425) 285-8696 Contact Us

Pro Kirkland Plumber uses non-invasive leak detection technology — acoustic listening equipment, thermal imaging cameras, and pressure isolation testing — to find hidden water leaks in walls, under slabs, in ceilings, and underground. Once located, our plumbers repair the leak the same day in most cases. Early detection prevents the water damage, mold growth, and structural deterioration that follow an unaddressed leak.

The Problem

Why Hidden Leaks Cause So Much Damage

A pinhole leak in a copper supply line behind drywall can run for weeks before you see a stain. In that time, the moisture saturates framing, promotes mold growth (which can colonize in 24 to 48 hours in the Pacific Northwest's humidity), and damages subfloor or ceiling materials. Slab leaks — where the supply line runs under or through the concrete foundation — are even harder to detect. You might notice a warm spot on the floor, hear running water when nothing's on, or see an unexplained spike in your water bill. Kirkland homes built in the 1960s through 1980s with copper supply lines are particularly susceptible to pinhole leaks caused by water chemistry, while homes with polybutylene (poly-B) lines can develop failures at any connection point.

Our Solution

How We Find and Fix Hidden Leaks Across Kirkland

We don't guess where the leak is and start cutting holes. Our detection process uses three complementary technologies: acoustic listening devices that amplify the sound of pressurized water escaping through a crack or hole; thermal cameras that reveal temperature differences behind walls and under floors caused by moisture; and pressure isolation tests that narrow the leak to a specific pipe section. Once we pinpoint the location, we make the minimum necessary opening to access and repair the leak — patch the pipe, replace the fitting, or reroute the section if the pipe material is failing systemically.

How It Works

How Leak Detection Works

Review Symptoms and History

You describe what you're seeing — water stain, high bill, damp spot, sound of running water. We ask about your home's age, pipe material, and any previous plumbing work.

Pressure Test the System

We shut off all fixtures and watch the meter. If it moves, water is escaping somewhere. We then isolate sections to narrow down which line has the leak.

Acoustic and Thermal Scanning

We listen for the leak with acoustic amplification and scan walls, floors, and ceilings with thermal imaging to find moisture concentrations without opening anything up.

Pinpoint and Access

Once located, we make the smallest possible opening to expose the leak. No unnecessary demolition — just targeted access.

Repair and Restore

The pipe is repaired or replaced, the system is pressure-tested to confirm the fix, and we clean up. Drywall or flooring repair is coordinated if needed.

Warning Signs

Signs You Have a Hidden Leak

Water bill increased significantly without a change in usage — even a small hidden leak can waste thousands of gallons per month
Damp or discolored spot on a wall, ceiling, or floor that doesn't dry out
Sound of running water when all fixtures are off — pressurized water escaping through a crack
Warm spot on a floor (slab leak in a hot water line) or unexplained puddle near the foundation
Musty or moldy smell in a room without an obvious moisture source
Water meter spinning when nothing in the house is running

Common Questions

Leak Detection Questions From Kirkland Homeowners

We use acoustic listening equipment to hear pressurized water escaping, thermal cameras to see moisture through walls and floors, and pressure tests to isolate which pipe is leaking. This combination pinpoints most leaks within a few inches without cutting into anything.

A professional leak detection visit typically runs $200 to $500 depending on the complexity. The repair cost is separate and depends on the leak location and pipe material. We quote everything before starting work.

Yes. Slab leaks are one of the most common reasons we're called. Acoustic equipment is especially effective for slab leaks because the sound travels through the concrete. We can locate the leak without jackhammering exploratory holes.

Yes — in the Pacific Northwest's humidity, mold can begin growing within 24 to 48 hours of sustained moisture. The sooner a leak is found and fixed, the less likely you'll need mold remediation. We can connect you with a trusted remediation contractor if needed.
