Rodent Proofing & Pest Exclusion
in Burke Mountain, BC
Burke Mountain is one of the most recently developed residential areas in Coquitlam, with construction ongoing on the steep slopes of Burke Mountain above the existing Coquitlam community. Homes here are built on terrain that was forestland until recently, on soils that are a mix of shallow glacial till and organic forest soils. The steep topography creates significant drainage challenges, and the cut-and-fill grading required on these lots alters natural drainage patterns in ways that can produce unexpected water intrusion for individual properties.
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 Burke Mountain — What We See Here
Because Burke Mountain development is recent, the crawlspace issues we address here are different from the decades-old moisture damage we encounter in older communities. The challenges are more often about site drainage design — fill areas that have not drained as intended, grading that channels runoff toward foundations, and drainage systems that were adequate under normal conditions but overwhelmed during the heavy storms that are increasingly common in this region. Proactive assessment and drainage correction are the right approach for Burke Mountain homeowners.
