Rodent Proofing & Pest Exclusion
in Aldergrove, BC
Aldergrove is an agricultural-edge community on the eastern flank of Langley Township, close to the BC-Washington border and the Aldergrove Lake Regional Park. The residential core has a small-town character with housing stock from the 1950s through the 1970s, and the surrounding area transitions quickly to agricultural land and acreage properties. The soils in the Aldergrove area are a mix of silt loam and clay, with drainage characteristics that vary with topography across the community.
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.

About Aldergrove — What We See Here
Rural and semi-rural properties around Aldergrove often have crawlspaces that have had minimal professional attention over their lifetimes. Older farmhouses and rural residences in this community may have the most challenging conditions we encounter: very old structural wood, improvised moisture control measures applied over the decades, and rodent or pest damage that has never been properly addressed. We bring the same thoroughness to rural Aldergrove properties as to suburban homes closer to the Langley core.
