Rodent Proofing & Pest Exclusion
in Brentwood, BC

Brentwood is one of Burnaby's most actively developing neighbourhoods, with rapid densification around the Brentwood Town Centre SkyTrain station transforming what were single-family residential streets into a high-rise urban district. Beneath this transformation, however, there remains a significant inventory of older single-family homes on crawlspace foundations in the surrounding streets — homes that were built in the 1960s and 1970s and have not had major crawlspace work since original construction.

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.
