Rodent Proofing & Pest Exclusion
in Ladner, BC

Ladner is the historic heart of Delta municipality, a small town centre surrounded by the flat Fraser River delta farmland that characterizes much of this part of the Lower Mainland. The residential areas of Ladner proper sit on some of the most challenging hydrology in the region — flat ground, high water tables, fine-grained delta soils with poor drainage, and proximity to the river channels and sloughs that lace through the delta. Managing crawlspace moisture in Ladner is as much about mechanical water removal as it is about vapour barriers.

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.
