Crawl Space Treatment in Langley
Fort Langley heritage crawl spaces, ALR corridor rat pressure, Brookswood moisture

In an uninspected Fort Langley heritage crawl space from the 1930s, typical findings: no or deteriorated original vapour barrier, Norway rat runs from the Fraser River corridor, carpenter ant frass, and moisture levels above modern standards.

Yes — Brookswood homes adjacent to ALR agricultural land carry moisture from BC wet winters and above-average agricultural valley humidity.

Yes — ALR-adjacent acreage crawl spaces face agricultural rat pressure and require rodent-grade exclusion sealing from inside as well as the perimeter.

Pest treatment and vapour barrier work are separate line items. Both are often needed on older Langley homes.

Yes. Renovation is the best time.

Yes. Agricultural valley humidity keeps crawl-space conditions more persistently moist than in purely urban Metro Vancouver areas.

Common in Fort Langley and Brookswood homes — we treat both when both are present.

Through existing hatches. Heritage construction sometimes has unusual hatch locations from the original building era.
