BC Slab Leak Detection: Complete Guide for Homeowners & Strata
Complete guide to slab leak detection in BC. How to identify slab leaks, detection methods, costs, and solutions.
A slab leak is a leak in a pipe within or beneath a concrete foundation. It is one of the most challenging leak scenarios. The pipe is hidden in concrete, water can migrate laterally, and detection requires specialized equipment. Common in townhouse and apartment complexes from 1970s-1990s.
Indicators: warm spots on concrete floors (hot water leak), running water sound when off, unexplained bill increase, buckling hardwood or laminate over slab, water at baseboards, musty odours, cracks in tile, meter running when off.
Detection methods: Thermal imaging is primary — hot water leaks create distinct temperature patterns in infrared. Acoustic detection locates sounds of escaping water within the slab. Tracer gas confirms when other methods are inconclusive.
Cost: $600-$1,500 for basic investigation, $1,000-$2,500 for comprehensive multi-technology investigation. Most insurance covers slab leak detection.
