Entry Point Exclusion in New Westminster
Queens Park century-old crawl vents, heritage sill-plates, and Fraser River pressure

Yes. The Fraser River probes every opening continuously — foam and caulk fail within days under this pressure. Rodent-grade hardware cloth holds. The Fraser is why exclusion is more important here than in inland cities.

Original crawl-space vent mesh deteriorated since the early 1900s, century-old sill-plate settling, failed period-era pipe penetration caulk, and door frame shrinkage gaps from 100 years of wet-dry cycles.

Heritage-appropriate materials are used at entry points in ways that do not alter character-defining exterior elements.

Yes. On Queens Park heritage homes, both types of entry geometry are present and addressed together.

As long as the surface it is anchored to.

Yes. Heritage home audits are a common service — we photograph and document every entry point.

Original period-era pipe penetrations on Queens Park heritage homes require material-matched approach — rigid metal mesh around the pipe and heritage-appropriate patching at the wall penetration. We note when a heritage mason or restoration contractor is needed for the finish layer.

Exclusion sealing at below-grade and grade-level penetration points typically does not require heritage permits. Roofline and soffit work may require consultation with the City of New Westminster heritage officer on fully designated properties. We note when that applies.
