Rodent Proofing & Pest Exclusion
in Matsqui, BC

Matsqui Prairie is the flat agricultural floodplain west of Abbotsford proper, one of the most productive farming areas in BC and one of the most challenging environments for crawlspace moisture management. The prairie sits essentially at river level, protected from seasonal flooding by the Matsqui dyke system. Within the dyked area, the water table is close to grade through much of the year and can rise to near-surface levels during periods of heavy precipitation or high river levels.

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.
