Water Leak Repair Guide

Residential Leak Detection

Residential Water Leak Detection

Homes rarely announce a leak at the point it is happening. Water travels along framing, pipe runs and slab edges, so the wet patch on a ceiling is often metres from the source. We locate and document the origin non-invasively before anything is opened up.

Symptoms we're called for

  • A utility bill that climbs without a matching change in habits
  • A water meter that keeps moving with every fixture closed
  • Staining, bubbling paint or a soft spot on a ceiling, wall or floor
  • A musty smell, persistently high humidity or a warped baseboard
  • Warm spots on a slab floor or a hiss near a wall or cabinet

Property types

  • Single-family homes, townhouses and duplexes
  • Condos and apartments (interior piping and shared assemblies)
  • Homes on slab-on-grade and homes with crawlspaces or basements
  • Pre-purchase and pre-renovation investigations

Methods used

  • Acoustic listening and correlation to hear water escaping under pressure
  • Thermal imaging to find temperature anomalies below finished surfaces
  • Moisture metering and mapping to trace the extent of migration
  • Tracer gas for lines and voids where acoustic access is limited
  • Line tracing and pressure isolation to confirm the leaking run

Limitations, stated plainly

  • Detection locates and documents; we do not perform repairs
  • Concealed fittings behind sealed finishes may require a small access point to confirm
  • Some leaks only present under specific conditions (hot water use, rain, pressure cycles)

What you receive

  • A written report with the located source and the evidence behind it
  • Photographs and thermal/moisture readings annotated on site
  • A moisture map showing how far water has travelled
  • Recommended next steps, including the trade to call if repair is needed

Next steps

  • Send the report to your insurer or adjuster as part of a claim
  • Give the locator's findings to a licensed plumber or restoration contractor
  • Re-test after repair to confirm the source is resolved
