10 long-form pillar guides
Everything you need to know about every major leak type.
Comprehensive guides for property owners, building managers, and trades. Each guide covers the symptoms, the diagnostic process, the technologies, the costs, and 10+ FAQs — written by 25-year detection experts at Leak.ca.
Slab Leak Detection
Slab leaks are water leaks inside the plumbing lines beneath a concrete floor.
Underground Service Line Leak Detection
Your underground water service line is the buried pipe running from the city water main under the street, up to the main shut-off valve inside your home.
Strata Inter-Unit Leak Detection
When water shows up in one unit from a leak somewhere above, the most important question isn't 'how do we fix it' — it's 'who's responsible'.
Hidden Water Leak Detection
Hidden water leaks — behind walls, above ceilings, under floors, behind appliances — are the most common source of insurance claims and the most common reason homeowners call us.
Roof Leak Detection
Where water shows up on your ceiling is almost never where it entered the roof.
Pool & Spa Leak Detection
Pool and spa leaks are notoriously hard to diagnose — water disappears, and the question is whether it's the shell, a fitting, the plumbing, or the equipment pad.
Commercial Leak Detection
Commercial leaks cost more than the leak itself — they cost tenant downtime, business interruption, insurance deductibles, and reputation.
Ground Penetrating Radar (GPR)
GPR uses radar pulses to image subsurface features — buried pipes, voids, rebar, tanks, soil layers — without disturbing the surface.
Thermal Imaging Leak Detection
Infrared thermal imaging detects the temperature differential caused by water moisture in walls, ceilings, floors, slabs, and façades.
Buried Oil Tank (UST) Detection
Undisclosed buried oil tanks on BC properties — typically heating-oil tanks installed in the 1940s–1960s and abandoned in place when homes converted to gas — are a major environmental liability and a routine real-estate deal-killer.
