Building Envelope Water Penetration Testing in British Columbia
When a tower leaks at a window, a curtain wall, or a balcony slab, the cause is usually a specific failed detail — and proving which one requires controlled field water testing, not guesswork. Building envelope water penetration testing replicates wind-driven rain on the assembly to find exactly where, and why, water enters.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Envelope water penetration testing applies controlled water (and, where needed, air pressure) to a window, curtain wall, facade, balcony or deck assembly following recognized field methods, while the interior is observed for entry. It isolates the failing detail — a gasket, sealant joint, flashing or membrane — so envelope consultants, engineers and strata councils can specify a targeted repair rather than a costly blanket re-clad.
- Failed window and curtain-wall gaskets, sealants and drainage
- Curtain-wall and facade joint and transition failures
- Balcony, deck and threshold membrane and flashing defects
- Wind-driven rain entry at penetrations and transitions
Why It Matters
Proves the exact failing detail for a targeted repair
Supports envelope consultant, warranty and litigation documentation
Avoids blanket re-cladding to chase a single entry point
Building Envelope Water Penetration Testing — FAQ
Controlled field water testing replicates wind-driven rain on the assembly — by calibrated spray and, where required, an air-pressure chamber — while the interior is observed for entry. This isolates the specific failed gasket, joint, flashing or membrane so the repair targets the real source.
A stain shows where water surfaces, not where it enters — and envelope water can travel far inside the assembly. Controlled testing reproduces the leak on demand and pinpoints the failing detail, which is the defensible basis for a consultant's repair specification.
