Rodent Proofing & Pest Exclusion
in West Vancouver, BC
West Vancouver occupies some of the most dramatically sloped residential terrain in Canada, with properties in Horseshoe Bay, Cypress Park, and the higher elevations of the British Properties sitting on terrain that in some cases exceeds 30 degrees. Combined with the North Shore's substantial annual precipitation and the thin, quick-draining soils over bedrock, managing water around foundations in West Vancouver requires careful site-specific engineering rather than standard solutions applied uniformly.
Rodents find crawlspaces attractive for the same reasons moisture does well there: it's dark, protected, relatively warm, and — in homes without proper exclusion — easy to get into. Rats (particularly Norway rats, common throughout Surrey and the Fraser Valley) and house mice can squeeze through gaps as small as a quarter-inch. They enter through uncapped foundation vents, gaps around utility penetrations, deteriorated sill plate joints, and even through the condenser lines of HVAC systems if protective screens are missing or corroded.
Our rodent-proofing process starts with a perimeter audit: we walk the exterior of the foundation looking for every possible entry point, then we move inside the crawlspace to identify any gaps that weren't visible from outside. Foundation vents are fitted with heavy-gauge galvanized steel mesh or replaced with sealed covers. Gaps around plumbing and electrical penetrations are packed with stainless steel wool and sealed with caulk or foam. Damaged sill plates are repaired. If the foundation vent openings are large or irregularly shaped, we use pre-formed steel exclusion panels rather than flexible mesh, which rodents can push past over time.

About West Vancouver — What We See Here
The housing stock in West Vancouver ranges from modest post-war homes in Dundarave and Ambleside — many of which have classic 1950s and 1960s crawlspace foundations with the moisture and structural challenges that implies — to very large, high-value custom homes built recently on difficult hillside sites. Both ends of the spectrum require thoughtful crawlspace work, but the implications of getting it wrong differ dramatically. For a modest Ambleside bungalow, a failed encapsulation system means ongoing mold and moisture problems. For a multi-million dollar British Properties estate, it means damage to high-end finishes and systems, and potential liability questions at resale.
We approach West Vancouver crawlspace work with the level of attention to detail that the properties demand. Drainage systems on steep sites must be carefully designed to prevent erosion at discharge points. Structural repairs must account for the additional loads imposed by slope and any retaining walls integrated with the foundation. We work collaboratively with homeowners and, where the project scope warrants it, with structural engineers and landscape architects to ensure drainage systems function as a coordinated whole.
