Building Envelope Leak Detection in West Vancouver, BC
Where BC weather gets into BC buildings: wall assemblies, window and door interfaces, balconies, parapets, and roof-wall junctions — water entry paths traced to their source with thermal imaging, moisture mapping, and controlled water testing, not guesswork recladding. Serving West Vancouver and the Metro Vancouver since 1999.

West Vancouver context that shapes the work
Property stock: BC's highest-value detached stock — metered water (District leak-adjustment program), estate properties with pools, extensive irrigation, and long private drives.
Ground conditions: Thin rocky soils put most utilities shallow and image crisply; granite below returns nothing, which itself maps where rock starts — useful for excavation planning.
Who calls us in West Vancouver
- Owners with stains that return every storm season
- Strata councils facing envelope-vs-unit disputes
- Buyers of rainscreen-era and pre-rainscreen buildings
- Managers tired of repeat caulking that never holds
The West Vancouver service set
Building Envelope Leak Detection
The ground-based core: trace the path, find the entry.
ViewWindow & Door Leak Detection
The interfaces where most envelope water actually enters.
ViewBalcony & Exterior Leak Detection
Deck membranes, railings, and thresholds — the repeat offenders.
ViewAerial Façade & Envelope Thermal
Full elevations imaged without swing stages.
ViewRoof Leak Detection
Where 'wall leaks' often begin — above them.
ViewThermal Imaging Technology
How the instrument actually reads wet assemblies.
ViewHow the West Vancouver investigation runs
- 1
Symptom mapping
When it leaks (which weather, which wind direction), where it shows, and the assembly's history — the pattern usually narrows the suspect elevation before testing starts.
- 2
Thermal & moisture survey
Interior and exterior imaging plus moisture mapping bound the wet zone and trace it upstream — water travels inside assemblies, and the trail is readable.
- 3
Controlled water testing
Calibrated spray and isolation testing on the suspect interfaces — window by window, joint by joint — until the entry reproduces on demand. Reproduction is proof.
- 4
Entry-point report
The documented path: where water enters, how it travels, what it's wetting — scoped for the right trade, sized to the actual defect instead of the whole elevation.
Why West Vancouver chooses Leak.ca
- Finds the entry point, which is rarely where the stain is
- Controlled water testing proves the path before repairs are priced
- Documentation that separates envelope from plumbing definitively
- Aerial elevation imaging when ladders and stages can't reach
West Vancouver questions, answered
What does West Vancouver weather do to building envelopes?
Metro Vancouver exposure does the testing for free — wind-driven rain finds every unsealed lap and tired gasket, and West Vancouver's storm seasons re-run the experiment yearly. Investigation here leans on exposure history: which elevations face the weather, and which storms produce the symptom.
Which West Vancouver buildings need envelope investigation most?
BC's highest-value detached stock — metered water (District leak-adjustment program), estate properties with pools, extensive irrigation, and long private drives. The pre-rainscreen share of that stock carries the highest stakes — assemblies without drainage cavities hold what they catch — while newer construction mostly presents interface failures: windows, doors, decks, and penetrations. Era points the investigation; testing proves it.
What does building envelope leak detection cost in West Vancouver?
Province-wide pricing — no regional premium for West Vancouver or anywhere in the Metro Vancouver. Single investigations start in the low-to-mid hundreds; larger properties and multi-system files are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes. Mon–Sat, 8am–6pm PT.
The stain is on the ceiling by the window — isn't the window the leak?
Maybe — and maybe the parapet ten metres up, the deck threshold above, or a flashing lap two floors higher. Envelope water travels: down studs, along plates, across membranes, exiting where gravity and openings allow. Repair budgets die when the exit gets treated as the entry. Tracing upstream with imaging and controlled testing is how the actual entry gets found — and why our repairs-from-findings tend to be small and final.
How does controlled water testing work, and why not just wait for rain?
Because rain tests everything at once and proves nothing in particular. Controlled testing isolates: calibrated spray on one interface at a time, in sequence, with the interior monitored — when the leak reproduces, you know the path, not just the symptom. It's the difference between evidence and coincidence, and it's what turns 'reseal everything' into 'fix this flashing'.
