Why Entry Point Exclusion Is a Particular Issue in Vancouver
Vancouver's older housing stock generates more entry points than most Canadian cities. Pre-war character homes in East Van, Kits, and Dunbar have wood sill plates, original vent covers with corroding mesh, and utility penetrations that were roughed in decades before rodent exclusion was a building consideration. Each renovation layer adds new openings without necessarily closing old ones.
Rodent-grade exclusion is not cosmetic caulk — it is galvanized metal, hardware cloth, and steel-backed foam installed at gaps that are confirmed to be the actual entry paths, not a general perimeter wipe. The goal is a sealed structure, not a sealed invoice.
What shapes exclusion work in Vancouver:
- Sill plate weathering: Vancouver's annual rainfall accelerates wood deterioration at grade-level sill plates — entry gaps that were caulked five years ago often reopen as the sill softens. Metal replaces what failed permanently.
- Utility penetrations: Gas, cable, and water lines on older East Van and Kits properties often pass through undersized knockout holes with no backfill — a gap around a gas line sleeve is frequently the primary mouse entry point and is easily missed on a non-invasive inspection.
- Lane-side exposure: Laneway-facing walls on ADUs and character homes see more rodent staging than street-facing walls — exclusion plans address both perimeters, not just the obvious front.
What Entry Point Exclusion in Vancouver Involves
We close the gaps that matter — prioritized by size, location, and evidence of use. This is targeted work: a written list of openings, materials used at each, and photographs of before and after. You get a document you can hand to a landlord, strata, or insurer that shows exactly what was sealed and where.
For strata buildings we are explicit about which closures are inside the unit boundary versus what requires common-property access — you are not charged for a partial job that stops at the drywall while the building chase stays open.

Entry Point Exclusion Across Vancouver Neighbourhoods
East Vancouver and Renfrew pre-war blocks have the highest concentration of unaddressed sill plate and lane-side utility gaps — exclusion here usually starts at grade and works up, not across random baseboards.
Kitsilano and Kerrisdale character homes often have three or four past-owner attempts at the same gap — caulk layers over the original opening. Metal goes in over the whole footprint, not another patch on top.
Yaletown and False Creek strata buildings face the common-property boundary question — we scope exactly where our seal ends and where building access is needed so councils have a clear decision point.
Dunbar and Point Grey detached garages and attached garage headers are the most common entry points on larger lots — garage-to-house penetrations and header gaps are on every check list.
Mount Pleasant and Commercial Drive dense mid-rise blocks add shared plumbing wall penetrations — we note which gaps are accessible from the unit and which require adjacent unit or building access.
