Water Leak Detection in Duncan
Commercial and government water leak detection in Duncan. Non-invasive methods, insurance-ready reports, no detection no charge.
Why Duncan commercial property managers call AnyLeak
Duncan’s commercial core, Cowichan Valley wineries, and First Nations administrative facilities present diverse leak detection scenarios. Combined with the realities of BC’s climate — wet winters, freeze-thaw cycles, salt air on the coast, dry summers inland — leaks in Duncan can develop in places they wouldn’t elsewhere.
AnyLeak has located leaks across British Columbia since 1999. We deploy acoustic detection, thermal imaging, electronic tracer gas, underground GPR, drone inspection, and pressure and tracer gas — whichever combination matches what you’re dealing with.

Thermal ImagingInfrared cameras reveal moisture and temperature anomalies invisible to the eye.
Electronic / Tracer GasRadiant heat, pool/spa, roof membrane, depressurized lines.
Underground (GPR)Buried mainlines and irrigation without trenching the property.
Drone InspectionAerial thermal scans for large roofs and facilities.
Pressure & Tracer GasCombined method for complex multi-zone systems.
Common commercial leak scenarios in Duncan
- Unexplained water bills that won’t drop even with no apparent usage.
- Damp spots, warm spots, or warped flooring on slab-on-grade properties.
- Persistent moisture at the base of an interior wall or behind cladding.
- Pressure loss on irrigation mainlines without visible surface water.
- Pool, spa, or hot tub losing water beyond evaporation.
- Hot-water recirculation loop pressure loss in larger Duncan properties.
- Roof or building envelope moisture intrusion after heavy rain.

A Closer Look at This Service
The cost of finding a leak is small compared to the cost of the damage it causes. A month of undetected leaking can wet insulation, rot framing, wash soil, and attract mould in the time it takes to book an inspection.
A city’s building code, its typical construction era, and its soil behaviour all leave their fingerprints on the leaks it produces. Reading those fingerprints is what makes an investigation accurate on the first visit.
The technician works methodically through the checklist, explaining each step as it happens. Questions are welcome at every stage, and the approach is adjusted when the evidence points in a new direction.
How the Investigation Is Delivered
Every investigation follows the same disciplined sequence: consultation, survey, testing, cross-verification, marking, and documentation. The sequence is deliberate, and each step builds on the last.
- Step 1: Consultation to understand the situation and the history
- Step 2: Site survey and indicator mapping
- Step 3: Testing of the suspected systems with matched methods
- Step 4: Cross-verification of the finding
- Step 5: Marking and documentation
- Step 6: Written, dated report
The third mistake is assuming the leak is in the same room as the stain. Water travels along structure for surprising distances, and the visible stain is almost never the source. The investigation traces the path before any repair is planned.
What This Costs
Every property is different, which is why pricing follows the investigation plan rather than a menu. The free consultation defines the scope, and the fixed quote follows it. What you are quoted is what you pay.

Insurance and Documentation
For BC policyholders, the practical value is speed: the claim starts with the report already in hand, instead of weeks of back-and-forth while the insurer tries to establish what happened.

What the Report Includes
You keep the report. It documents the finding, the condition at the time of the investigation, and the guidance for the repair, which is useful for warranty, insurance, and future reference.
Reports are dated and structured so that any licensed contractor can take the marked location and proceed directly to the repair. They are also accepted by insurers, engineers, property managers, and, when needed, in dispute processes.
When to Call
Call when the indicator is persistent, when it repeats after a repair, or when it is accompanied by a second indicator. A single passing event can be a coincidence; a pattern is a leak.
Call before the damage becomes visible if the meter is moving with everything off. That reading is the earliest and cheapest moment to act, and acting early is what makes the repair small.
How to Prepare the Property
The best preparation is information: when the issue started, what changed around that time, what the weather did, and what has already been tried. That history is often more valuable than any instrument.
Nothing else needs to be done. The investigation does not require demolition, preparation of the systems, or any work on your part beyond access. Showing up with the history is the whole preparation.
Common Questions
Is this service non-invasive?
Yes. Every method used works from the surface and leaves no marks. Nothing is cut, dug, or permanently marked during the investigation.
How accurate is the location?
With cross-verified methods, locations are typically within a metre or less, and slab locations within inches.
Is the report useful for insurance?
Yes. The report documents the cause, the extent, the methods used, and the readings, structured for claims and engineering review.
How long does an investigation take?
Most property-level investigations complete within a day, and the written report follows within one to two business days.
Do you repair leaks?
No. Detection and documentation are the service. The report guides the repair contractor to the exact location.
What does this cost?
The quote is fixed before work begins, based on the scope defined in the free consultation. What you are quoted is what you pay.
Call (604) 269-5325 or email info@anyleak.ca for a free consultation. The report is dated, documented, and written to the standard insurers and engineers expect.
