Leak Detection in Toronto: How to Spot Hidden Water Problems
Not every leak is visible. Hidden water loss can show up through damp areas, staining, unexplained sounds, changes in water use, or recurring moisture where no obvious source is present.

Signs worth investigating
Watch for staining that grows, musty odours, damp flooring or drywall, water sounds when fixtures are off, or repeated moisture around the same area. A sudden unexplained change in water use can also justify investigation.
Document before the visit
Take photos, note when the signs appear, and record whether they change with rain, appliance use, or specific fixtures. That timeline can help narrow the likely source.
Ask about diagnostic scope
Confirm what testing is included and whether the provider uses non-destructive methods before opening walls or ceilings. If repair work is separate from diagnosis, ask how the next step will be quoted.
