Our Leak Detection Process

01

Meter Test

We check your water meter with all fixtures off to confirm whether a leak exists and estimate its size.

02

Pressure Testing

Sections of your plumbing are isolated and pressure-tested to narrow down the location of the leak.

03

Acoustic Detection

Specialized listening equipment detects the sound of water escaping from pressurized pipes through walls, floors, and slabs.

04

Thermal Imaging

Thermal cameras detect temperature changes caused by wet areas, pinpointing leaks behind walls without cutting into them.

Leak Detection FAQ for Seattle Homeowners

How often should Seattle homeowners get leak detection?
Given Seattle's 160+ rain days per year averaging 38 inches, most homeowners benefit from leak detection at least once a year. Year-round moss and algae on roofs and driveways often makes spring or fall the optimal time to schedule service.
What home types in Seattle most need leak detection?
Craftsman bungalows and Mid-century ranches are the most common home types in Seattle and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How do I know if I have a hidden water leak?
Signs include unexplained high water bills, the sound of running water when fixtures are off, warm spots on floors (possible slab leak), water stains on walls or ceilings, and musty odors.
What is a slab leak?
A slab leak is a water or sewer pipe leak located beneath the concrete foundation of your home. They're caused by pipe corrosion, poor installation, or soil movement. Slab leaks are serious and require professional detection.
How accurate is professional leak detection?
Modern acoustic and thermal equipment can locate leaks to within inches. This precision dramatically reduces the amount of excavation or wall opening required to make repairs.
What does leak detection cost?
Leak detection services typically run $150–$400. This cost is usually offset by the savings in repair costs from not cutting open walls or floors in the wrong location.
