Rodent Proofing & Pest Exclusion
in Port Moody, BC
Port Moody occupies the eastern tip of Burrard Inlet, with residential development largely on the steep slopes rising above the waterfront. This geography creates a very specific drainage situation: water moving downslope through the thin glacially-derived soils reaches the residential areas quickly during heavy rain events, and properties on the lower slopes can experience significant lateral water pressure against uphill foundation walls. The marine proximity adds ambient humidity even on dry days, and the inlet's position means marine fog is a common morning condition through much of the year.
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 Port Moody — What We See Here
Homes in the established College Park and Glenayre neighbourhoods are primarily from the 1960s and 1970s, with crawlspace foundations that have dealt with these conditions for decades. The sloped sites in these areas create natural opportunities for gravity drainage improvements that we can take advantage of — a properly graded perimeter drain routed to daylight on the low side of the property can be very effective here without requiring a sump pump. We assess each site's specific topography to determine whether gravity or mechanical drainage is the right approach.
The newer developments around Newport Village and the inlet waterfront area are generally more modern construction on concrete slabs, so crawlspace work in Port Moody tends to be concentrated in the older hillside neighbourhoods. Heritage-era homes near St. Johns Street and the original townsite occasionally have older construction techniques that need to be understood before any crawlspace intervention is planned.
