Rodent Proofing & Pest Exclusion
in Coquitlam Center, BC
The Coquitlam Centre area — surrounding the regional shopping mall and extending into the adjacent residential streets — has a mix of housing types from the 1970s and 1980s that represent the period when this part of Coquitlam transitioned from low-density suburban to more urban character. Single-family homes on crawlspace foundations from this era are common in the streets surrounding the commercial core.
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 Coquitlam Center — What We See Here
The soil conditions in central Coquitlam are predominantly clay-loam, similar to other mid-slope communities in the Tri-Cities area. Drainage is better than in the flatland communities to the south but still prone to surface water accumulation after heavy rain events. We work regularly in this area on encapsulation and mold remediation projects for homes that have accumulated moisture damage over the decades of their existence.
