Rodent Proofing & Pest Exclusion
in Lougheed, BC

The Lougheed area of Burnaby spans both sides of the Lougheed Highway as it passes through the municipality, with residential neighbourhoods extending north toward Burnaby Lake and south toward the Brentwood area. Burnaby Lake, while now a regional park, influences the hydrology of the surrounding area — the water table in some residential blocks near the lake is higher than would be expected based on topography alone, and seasonal fluctuations correspond with the lake level.

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.
