Rodent Proofing & Pest Exclusion
in Clayton Heights, BC

Clayton Heights is one of Surrey's newest residential communities, developed primarily in the 2000s and 2010s on land that was previously agricultural. The neighbourhood is characterized by high-density residential development — townhouses, rowhouses, and single-family homes on relatively small lots — with modern construction standards that include better vapour control than older housing stock. Even so, the agricultural origins of the land mean that soil conditions can be challenging: organic-rich farm soils, high water tables in low-lying sections, and drainage infrastructure that is still maturing as the community develops.

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.
