Rodent Proofing & Pest Exclusion
in White Rock, BC

White Rock sits at the southwestern corner of the Lower Mainland, where the Semiahmoo Peninsula slopes down to the Strait of Georgia. The combination of proximity to saltwater, predominantly west- and south-facing exposure to Pacific weather systems, and the relatively older residential development on the hillside above the waterfront creates a distinct set of crawlspace challenges. Salt-laden air accelerates the corrosion of metal fasteners, vents, and drainage components. Soils on the steeper hillside sections drain quickly but can experience significant seasonal movement, while properties closer to sea level deal with a very shallow water table during wet periods.

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.
