Crawlspace Encapsulation
in Matsqui, BC
Matsqui Prairie is the flat agricultural floodplain west of Abbotsford proper, one of the most productive farming areas in BC and one of the most challenging environments for crawlspace moisture management. The prairie sits essentially at river level, protected from seasonal flooding by the Matsqui dyke system. Within the dyked area, the water table is close to grade through much of the year and can rise to near-surface levels during periods of heavy precipitation or high river levels.
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 Matsqui — What We See Here
Residential properties in the Matsqui area are predominantly rural and agricultural-residential, with farmhouses and rural homes on large lots. The crawlspace conditions in these properties reflect their location: high water tables, organic-rich soils with slow drainage, and in some cases a history of actual flooding before dyke improvements were made. We approach Matsqui crawlspace projects with the same robust drainage and pumping specifications we use for other low-lying floodplain communities.
