Why Crawl Space Treatment Is Relevant in Coquitlam
Coquitlam's Maillardville, Cape Horn, and South Coquitlam are the primary crawl-space treatment areas in the Tri-Cities. These neighbourhoods have 1940s to 1970s wood-frame homes where original crawl-space construction meets decades of BC wet winters — moisture accumulates in sub-floor framing, vapour barriers have long since deteriorated, and pest activity in the resulting conditions goes undetected until a problem surfaces above the floor.
The Coquitlam River's proximity to Maillardville and central Coquitlam amplifies external rodent pressure on crawl-space properties. Norway rat runs along perimeter framing in Maillardville crawl spaces are a consistent finding — the river corridor connects the external population directly to these crawl-space staging areas.
Cape Horn's hillside properties carry an additional challenge: downslope moisture migration creates persistently elevated humidity in crawl spaces on the lower foundation side, and the original vapour barriers in 1960s construction have absorbed 60 years of BC wet-season moisture.
What makes crawl-space treatment a priority in Coquitlam:
- Maillardville older crawl-space homes near the Coquitlam River: Original construction with deteriorated vapour barriers and active Norway rat corridor pressure creates the most consistent crawl-space treatment scenario in the Tri-Cities.
- Cape Horn hillside downslope moisture: Moisture migration against the downslope foundation side on older Cape Horn homes keeps crawl spaces elevated in humidity long after wet season ends.
- Original inadequate vapour barriers: 1940s to 1970s crawl-space construction in Coquitlam's older neighbourhoods frequently has no effective vapour barrier after decades of weathering.
