Crawlspace Encapsulation
in Edmonds, BC
Edmonds is one of the lower-elevation neighbourhoods in Burnaby, situated near the border with New Westminster and occupying relatively flat terrain. The soil conditions here are clay-dominant, and drainage to natural outlets is limited by the flat topography. Like many of Burnaby's mid-century residential areas, Edmonds has significant housing stock from the 1950s through the 1970s where crawlspace conditions have deteriorated over the decades.
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 Edmonds — What We See Here
Mold on subfloor framing is particularly common in Edmonds crawlspaces that we inspect. The combination of flat drainage, heavy soils, vented crawlspace design, and decades of Pacific Northwest wet seasons creates ideal conditions for persistent mold establishment. We address this through comprehensive remediation — mechanical removal of colonized material, antimicrobial treatment, encapsulation, and dehumidification — rather than partial measures that allow recurrence.
