Crawlspace Encapsulation
in West Vancouver, BC
West Vancouver occupies some of the most dramatically sloped residential terrain in Canada, with properties in Horseshoe Bay, Cypress Park, and the higher elevations of the British Properties sitting on terrain that in some cases exceeds 30 degrees. Combined with the North Shore's substantial annual precipitation and the thin, quick-draining soils over bedrock, managing water around foundations in West Vancouver requires careful site-specific engineering rather than standard solutions applied uniformly.
Crawlspace encapsulation is one of the most effective investments a homeowner in Surrey or the broader Lower Mainland can make. The process involves covering the crawlspace floor and walls with a continuous, heavy-duty polyethylene vapor barrier — typically 12-mil or 20-mil reinforced poly — then sealing every seam, penetration, and vent opening with industrial-grade tape and adhesive. The result is a fully conditioned environment that is physically isolated from ground moisture and the damp Pacific Northwest soil beneath your home.
The installation process begins with a thorough cleanup — removing old fiberglass batt insulation (which absorbs moisture and harbors mold), clearing any debris, and treating visible mold colonies. Technicians then install the vapor barrier across the ground, lapping it up the walls and piers, and sealing it to the stem wall with adhesive and mechanical fasteners. All vents are closed and sealed from the inside. Depending on the space, we may also install a commercial-grade dehumidifier calibrated to maintain relative humidity around 50 to 55 percent throughout the year.

About West Vancouver — What We See Here
The housing stock in West Vancouver ranges from modest post-war homes in Dundarave and Ambleside — many of which have classic 1950s and 1960s crawlspace foundations with the moisture and structural challenges that implies — to very large, high-value custom homes built recently on difficult hillside sites. Both ends of the spectrum require thoughtful crawlspace work, but the implications of getting it wrong differ dramatically. For a modest Ambleside bungalow, a failed encapsulation system means ongoing mold and moisture problems. For a multi-million dollar British Properties estate, it means damage to high-end finishes and systems, and potential liability questions at resale.
We approach West Vancouver crawlspace work with the level of attention to detail that the properties demand. Drainage systems on steep sites must be carefully designed to prevent erosion at discharge points. Structural repairs must account for the additional loads imposed by slope and any retaining walls integrated with the foundation. We work collaboratively with homeowners and, where the project scope warrants it, with structural engineers and landscape architects to ensure drainage systems function as a coordinated whole.
