Rodent Proofing & Pest Exclusion
in Langley, BC
Langley encompasses both Langley City — a small, densely developed municipality with established residential neighbourhoods — and the much larger Langley Township, where residential development spans from urban infill near Willowbrook to rural acreage properties in Brookswood, Salmon River, and Aldergrove. Crawlspace conditions across this range are quite diverse. The Willowbrook and Walnut Grove areas have significant numbers of homes built in the late 1980s and 1990s on relatively flat ground with clay subsoils, while the agricultural fringe areas are more variable, with some properties on older farmland with organic soils that are slow to drain.
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 Langley — What We See Here
The Langley City core has housing stock dating back to the early 1960s, with some of the most significant moisture and structural issues we see in the region. Crawlspaces in homes of this era were built with wood posts sitting directly on concrete pads — sometimes directly on soil — and fibreglass batt insulation that was marginal even when installed. After six decades of Pacific Northwest rainfall cycling through these crawlspaces, the moisture damage in original structural wood can be substantial. We often find multiple post replacements needed alongside encapsulation when working in the city core.
Fort Langley and Murrayville present heritage preservation considerations that add complexity to crawlspace work. Older homes in these communities sometimes have original construction methods and materials that require care to work around without damaging historically significant elements. We approach these jobs with that context in mind, matching repair materials to the era of the structure where possible and being conservative with interventions that could affect the character of the building.
