Signs You Might Have a Hidden Leak
- Your water bill has risen noticeably with no change in usage
- You can hear running water when every fixture is off
- A damp, warped, or discoloured patch on a wall, ceiling, or floor
- A musty or mouldy smell with no visible source
- A consistently damp or unusually green patch of lawn
- The water meter is still moving with everything in the house turned off
How Professional Leak Detection Actually Works
Real leak detection doesn't mean opening up drywall or flooring on a guess. Depending on the situation, it can involve:
- Acoustic listening equipment that picks up the sound of water escaping under pressure through pipe, floor, or wall material
- Thermal and moisture meters that identify temperature and moisture differences consistent with a hidden leak
- A water meter test checking whether the meter still registers usage with everything in the house shut off
- Pressure testing on isolated sections of the system to narrow down where a leak actually is before anyone opens anything up
Common Places Hidden Leaks Show Up in Winnipeg Homes
Under a concrete slab
A slab leak on an underground line can run for a long time before it's obvious above ground.
Behind walls in older homes
Ageing supply lines, especially around bathrooms and kitchens.
At the main water service line
The pipe running from the street connection into the house.
Around a water heater
A slow tank or fitting leak that pools quietly before it's visible.
Underneath a dishwasher or washing machine
A slow supply line or drain hose leak that goes unnoticed for months.

Why Finding It Early Actually Matters
An undetected leak doesn't just waste water and money — sustained moisture leads to mould growth, can weaken framing and subfloor over time, and in a slab leak specifically can affect the foundation. Catching it early is almost always cheaper and less disruptive than waiting until the damage becomes visible.
It's also worth a call to your insurance broker — some policies treat gradual, undetected leaks differently than sudden ones, and having it professionally diagnosed and documented matters if you ever need to make a claim.
What Determines the Cost of Leak Detection
Cost depends mainly on how accessible the suspected area is, how large the property or system is, and whether it's a straightforward single-fixture check or a whole-property investigation with no obvious starting point. A legitimate leak detection service gives you a clear price for the diagnostic step itself, separate from any repair work that follows — you approve each stage before it happens.
