Rodent Proofing & Pest Exclusion
in Abbotsford, BC

Abbotsford is the largest city in the Fraser Valley and the primary agricultural hub of the region. It straddles the transition between the flat Fraser River plain — the Matsqui Prairie — and the upland areas around Sumas Mountain and Vedder Mountain. This topographic divide produces very different crawlspace challenges in different parts of the city. Homes in the Clearbrook and Matsqui Prairie areas sit on some of the flattest, lowest, and most water-retentive agricultural soils in the region; the 2021 atmospheric river event that caused catastrophic flooding in the Abbotsford area demonstrated vividly how quickly these flat, low-lying areas can be overwhelmed by water.

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.
