Crawlspace Encapsulation
in Bridgeview, BC

Bridgeview is a mixed residential and light-industrial neighbourhood in north Surrey, sitting adjacent to the Alex Fraser Bridge approach and close to the Fraser River. The area occupies low-lying ground with a water table profile similar to Newton and parts of Richmond — close to grade through the wet season and subject to periodic flooding during major rain events or high freshet years. Many of the residential homes in Bridgeview are older properties on larger lots, some dating from the 1950s and 1960s, with crawlspaces that have had decades of exposure to these demanding conditions.

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.
