Rodent Proofing & Pest Exclusion
in Silver Valley, BC
Silver Valley is one of Maple Ridge's newest residential communities, carved out of forested hillside on the slopes above the Alouette River valley. Development here has been ongoing since the 1990s and continues today, with the community still adding new streets and neighbourhoods on the upper mountain slopes. The terrain is steep, the soils are a mix of shallow glacial till and more organic forest soils, and rainfall is higher than the valley floor due to the orographic effect of the adjacent mountains.
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 Silver Valley — What We See Here
New development on steep, forested hillsides brings specific crawlspace challenges. Cut-and-fill grading on steep lots creates abrupt changes in soil profile that affect drainage in non-intuitive ways. Fill areas may settle over time, creating drainage depressions adjacent to foundations. The original forest soil, when exposed by grading, can produce significant moisture release into adjacent crawlspaces. We work with Silver Valley homeowners on both older and newer homes to identify and address these site-specific drainage conditions.
