Rodent Proofing & Pest Exclusion
in Newton, BC
Newton is one of Surrey's most densely developed neighbourhoods, occupying the low-lying land between the Serpentine and Nicomekl river systems. This positioning gives Newton one of the most challenging crawlspace environments in the entire Lower Mainland: a high seasonal water table, flat terrain with limited gravity drainage, heavy clay soils that retain water for extended periods, and a housing stock heavily weighted toward the 1970s and 1980s when moisture management standards were minimal. Crawlspaces in this area deal with active water challenges that go well beyond the vapour-diffusion problem faced in higher, drier locations.
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 Newton — What We See Here
Sump pump systems are essentially mandatory for any crawlspace solution in the lower-lying parts of Newton. The water table in some blocks rises to within 12 to 18 inches of the crawlspace floor during wet periods, which means any unsealed section of the ground surface will produce active moisture intrusion. We design Newton drainage solutions conservatively — larger sump pits, higher-capacity pumps, and redundant battery backup — because the consequences of a system failure during a heavy rain event in this area are severe and the water rises quickly.
