Water Leak Detection in Vancouver, WA

A hidden leak falls into one of two categories, and each requires a different detection method entirely. A pressurized supply-line leak, water actively being pushed through a pipe under your slab or inside a wall, produces a specific acoustic signature. Sensitive listening equipment placed at accessible points can pick up that sound and triangulate its location through concrete or flooring, often to within inches, without any exploratory digging or demolition.

A drain-line leak is different. Drain lines aren't pressurized, so they don't produce the same detectable sound. Finding a leak or crack in a drain or sewer line means visual inspection with a fiber-optic camera, run through the line itself, watching for the point where water is escaping rather than flowing through.

Getting the method wrong wastes time and money. Running acoustic equipment on a drain line problem finds nothing, since there's no pressure to detect. Running a camera looking for a supply-line leak means potentially missing it entirely if it's not physically inside a drain pipe. Our leak detection specialists determine which type of leak the symptoms point to before choosing equipment.

A meaningful share of Vancouver homes, particularly ranch-style construction common through the 1960s and 1970s in neighborhoods spreading out from the original Bagley Downs and Hazel Dell core, sit on a concrete slab foundation with copper supply lines run directly underneath. Copper pipe from that era is well past the midpoint of its expected service life, and the clay-heavy soil common in Vancouver's upland areas shifts seasonally in a way that stresses buried pipe over decades, making slab leaks a genuine and recurring issue in these specific neighborhoods.

How do you find a leak without tearing up my floor?

Acoustic equipment listens for the specific sound a pressurized leak produces, which pinpoints the location through concrete or flooring without any excavation needed for the detection itself.

What's a slab leak?

A leak in a water supply line running underneath your home's concrete foundation, often first noticed as a warm floor patch, unexplained dampness, or an unusually high water bill.

How much does leak detection cost in Vancouver?

Standard acoustic detection runs $130 to $300. A slab leak detection runs $215 to $400. A drain line camera inspection, when that's the applicable method, runs $145 to $260.

How do I know if I have a hidden leak?

An unexplained rise in your water bill, a moving water meter with everything off, or a persistently damp or warm spot on the floor are the primary indicators worth investigating.

Can I confirm a leak myself with a meter test?

Yes. Turn off every fixture and appliance, note the meter reading, wait 15 to 30 minutes without using water, and check again. Any movement confirms a leak exists somewhere in the system.

What equipment do you use?

Acoustic listening devices for pressurized supply-line leaks, and fiber-optic cameras for drain-line inspection. The method depends on which type of leak the symptoms point to.

Are drain leaks detected differently than supply leaks?

Yes. Supply lines are pressurized and produce an audible sound acoustic equipment can locate. Drain lines aren't pressurized, so they're inspected visually with a camera instead.

Will detection tell me exactly where to dig or open a wall?

Yes. The point of the service is a precisely marked location, so any repair work that follows targets that exact spot rather than an estimated area.

Is leak detection covered by a guarantee?

Yes. If our marked location proves inaccurate, we return to re-diagnose at no additional charge.
