Resolve unexplained water bills, damp spots and recurring stains.
Some leaks don't read as leaks: a water bill that creeps up over months, a stain that returns every spring, a musty smell that never quite goes away. Hidden-source investigation is the methodical work of running every diagnostic in the right order — meter testing, isolation valving, acoustic, thermal, moisture — until the actual source is found. We treat these as engineering problems, not guessing games. When other detection teams have given up, we are typically the next call.
Detect Leaks is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.
We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.
Clients booking hidden source investigation often combine it with Pressurized Line Detection or Slab Leak Location — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.
On the rare jobs where no active leak is present, you receive a documented confirmation report — useful for insurance, real estate and your own peace of mind.
